8X squared +4x-112=0

Answers

Answer 1

8x² + 4x - 112 = 0

To solve this equation, we can use the quadratic formula, as follows:

[tex]\begin{gathered} x_{1,2}=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ x_{1,2}=\frac{-4\pm\sqrt[]{4^2-4\cdot8\cdot(-112)}}{2\cdot8} \\ x_{1,2}=\frac{-4\pm\sqrt[]{16+3584^{}}}{16} \\ x_{1,2}=\frac{-4\pm\sqrt[]{3600^{}}}{16} \\ x_1=\frac{-4+60}{16}=3.5 \\ x_2=\frac{-4-60}{16}=-4 \end{gathered}[/tex]

Answers

The quadratic function is expressed as

f(x) = - x^2 + 10x - 22

The y intercept is the value of y or f(x) when x = 0

Thus, to find the y intercept, we would substitute x = 0 into the function. Thus, we have

f(0) = - 0^2 + 10 * 0 - 22

f(0) = 0 + 0 - 22

f(0) = - 22

Thus, the y intercept of the function f is (0, - 22)

Water :60 ounces

Salt solution:60 ounces

Explanation

Step 1

set the equations

Let x represent the amoun of water forthe solution

let y represents the amount of solution ( 40% salt)

so

a)the scientific mixes water with the solution to obtain 120 ounces, so

[tex]x+y=120\Rightarrow equation\left(1\right)[/tex]

b)the mixture is 20% salt

so

salt fromwater+salt from solution( 40%) = salt in the solution (20%)

so

[tex]\begin{gathered} 0+0.4y=120*0.2 \\ 0.4y=24 \\ divide\text{ both sides by 0.4} \\ \frac{0.4y}{0.4}=\frac{24}{0.4} \\ y=60 \end{gathered}[/tex]

hence, the amount of salt solution is 60 ounces

,now to find x, replace the y value in equation (1)

[tex]\begin{gathered} x+y=120\Rightarrow equation\left(1\right) \\ x+60=120 \\ subtract\text{ 60 in both sides} \\ x+60-60=120-60 \\ x=60 \end{gathered}[/tex]

so, water : 60 ounces

therefore, the answer is

Water :60 ounces

Salt solution:60 ounces

Answers

Given the function below,

[tex]f(x)=\frac{x+2}{x^4-2x^3-x^2+2x}[/tex]

Let us now factorize the denominator

[tex]x^4-2x^3-x^2+2x[/tex]

First of all, let us factorize x out from the denominator.

[tex]\begin{gathered} x(\frac{x^4}{x}-\frac{2x^3}{x}-\frac{x^2}{x}+\frac{2x}{x}) \\ x(x^3-2x^2-x+2) \end{gathered}[/tex]

Therefore, x is a factor of the denominator.

Let us now factorize the remainder

[tex]x^3-2x^2-x+2[/tex]

Let us substitute x = 1 into the function to confirm if it is a factor.

[tex]\begin{gathered} x=1 \\ 1^3-2(1)^2-(1)+2 \\ 1-2-1+2=1+2-1-2=3-3=0 \end{gathered}[/tex]

Therefore, (x - 1) is a factor.

Let us now divide the function by (x - 1)

[tex]\frac{x^3-2x^2-x+2}{x-1}=\frac{\left(x-2\right)\left(x+1\right)\left(x-1\right)}{x-1}=(x-2)(x+1)[/tex]

Hence, the factors of the denominator are,

[tex]x(x-1)(x+1)(x-2)[/tex]

Therefore,

[tex]f(x)=\frac{x+2}{x(x-1)(x+1)(x-2)}[/tex]

Now, looking at both the numerator and the denominator, we can observe that there is no common factor between the numerator and the denominator.

Hence, there is no removable discontinuity.

Julieta has p pennies and n nickels.

He has at most $1 worth of coins altogether.

What is a Inequality :

Inequality, a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers or algebraic expressions.

Since p time = $0.1

So n times = $(0.1)n

Since p quarter = $0.25

So n quarters = $(0.25)n

Total of p times and n quarters = $[(0.1)p + (0.25)n]

This total answer has a minimum of $1 worth of mins all to get he.

So,

$[(0.1p + 0.25n)] ≤ 1

Answers

We are given the following line equation:

We are asked to determine the x and y-intercepts of the line. To do that, we will convert the given equation into the following form:

[tex]\frac{x}{a}+\frac{y}{b}=1[/tex]

Written in that form the value of "a" is the x-intercept and the value of "b" is the y-intercept. Therefore, we need to divide the given equation by 20 in order to get a 1 on the right side:

[tex]\frac{4x}{20}+\frac{5y}{20}=\frac{20}{20}[/tex]

Simplifying we get:

Answers

When two equation are parallel it means they have the same slope.

You have the equation:

[tex]y=-\frac{1}{2}x+6[/tex]

You can identify the slope(m) as the number next to the x in equation that follow the next form:

[tex]y=mx+b[/tex]

Then, the equation parallel to the given equation has an slope of:

m= - 1/2

Now, if we have a point of the equation we can find the value of the b (y-intercept) in the slope - intercept form of a lineal equation:

[tex]y=mx+b[/tex]

The given point is ( -4 , 2)

You have the next values:

m= - 1/2

y= 2

x= -4

Then we substitute that values:

[tex]2=-\frac{1}{2}(-4)+b[/tex]

And clear the b:

[tex]2=\frac{4}{2}+b[/tex][tex]2=2+b[/tex][tex]2-2=2-2+b[/tex][tex]0=b[/tex]

Now, we get the value of the slope (m= - 1/2) and the y-intercept (b=0)

Sumalee spent $42 on 2 rose bushes and 8 bunches of ornamental grass.What is the cost of one rose bush and the cost of one bunch of ornamental grass?#2

Answers

Let 'x' and 'y' be the cost of one rose bush and one bunch of ornamental grass.

Given that Castel paid $69 for 5 rose bushes and 8 bunches of grass,

[tex]5x+8y=69\ldots(1)[/tex]

Also, given that Sumalee paid $42 for 2 rose bushed and 8 bunches of grass,

[tex]2x+8y=42\ldots(2)[/tex]

Now that we have two equations and two variables. These can be solved using the Elimination Method.

Subtract equation (2) from (1) as follows,

[tex]\begin{gathered} (5x+8y)-(2x+8y)=69-42 \\ 5x+8y-2x-8y=27 \\ 3x+0=27 \\ x=\frac{27}{3} \\ x=9 \end{gathered}[/tex]

Substitute this value in (1) and obtain the corresponding y-value,

[tex]\begin{gathered} 5(9)+8y=69 \\ 45+8y=69 \\ 8y=69-45 \\ y=\frac{69-45}{8} \\ y=3 \end{gathered}[/tex]

So the simultaneous solution is obtained as,

[tex]\begin{gathered} x=9 \\ y=3 \end{gathered}[/tex]

Thus, the cost of one rose bush is $9 and the cost of one bunch of ornamental grass is $3.

Find the points on

Answers

Answer:

(-5, 101) or (1, -7)

Step-by-step explanation:

The gradient of a function is zero when its first differential is zero

Taking first derivative of y = x³ + 6x² - 15x + 1

we get
[tex]\dfrac{dy}{dx} = \dfrac{d}{dx}(x^3+6x^2-15x\:+\:1)[/tex]

[tex]= \dfrac{d}{dx}(x^3)+ \dfrac{d}{dx}(6x^2) - \dfrac{d}{dx}(15x)\:+\: \dfrac{d}{dx}(1)\\\\[/tex]

[tex]= 3x^2 + 2(6x) - 15 + 0\\\\\\= 3x^2 + 12x - 15x\\[/tex]

Set this first differential to 0, find the solution set for x

[tex]3x^2 + 12x - 15x =0[/tex]

This is a quadratic equation which will have 2 solutions for x.

First divide throughout by 3
[tex]= > x^2 + 4x - 5 = 0[/tex]

Factor the term:
[tex]= > x^2 + 4x - 5 = 0\\\\== > (x -1)(x + 5) = 0\\== > x - 1 =0 \text { or } x + 5 =0\\\\[/tex]

This means x = 1 or x = -5 is the solution set

To find the y value corresponding to these values of x, plug in each of these x values in the original equation and solve for y

Plug in x = 1 into equation x³ + 6x² - 15x + 1

=> 1³ + 6(1)² - 15(1) + 1

=> 1 + 6 - 15 + 1

=> -7

So one point is (1, -7)

Looking at the choices we can eliminate the first and  last choices

Looking at choices 2 and 3 we see that only one of them has x = -5 which is the other solution value. This is the second choice

So the correct answer is second choice
(-5, 101) or (1, -7)

Answers

To find the probability between two z-scores on a normal distribution, we can use a z-score table.

So, if we want the probability between 1.98 and -1.15, we need to do the following:

[tex]P(-1.15However, usually z-score tables go only from z = 0 and above, so we need a way to consult the negative z.

Since the normal distribution in symmetric around z = 0, we have that:

[tex]P(z<-1.15)=P(z>1.15)[/tex]

And since the whole distribution give a 100% probability, or an area of 1, we have that:

[tex]\begin{gathered} P(z<1.15)+P(z>1.15)=1 \\ P(z>1.15)=1-P\mleft(z<1.15\mright) \end{gathered}[/tex]

So, in the end, we have:

[tex]\begin{gathered} P(-1.151.15) \\ P(-1.15So, we can consult the values for the probabilities of z < 1.98 and z < 1.15 on the z-score table:[tex]\begin{gathered} P(z<1.98)\approx0.9761 \\ P(z<1.15)\approx0.8749 \end{gathered}[/tex]

So, the total probability is:

[tex]\begin{gathered} P(-1.15So, the probability is approximately 0.8510.

Make a table and a graph of y = 4x - 2.

Answers

To make the table first replace the given values ​​of x in the equation, operate, and with it, you get their corresponding coordinates in y. Then you have

If x = -2

[tex]\begin{gathered} y=4x-2 \\ y=4(-2)-2 \\ y=-8-2 \\ y=-10 \\ \text{Then you have the ordered pair (-2,-10)} \end{gathered}[/tex]

If x = -1

[tex]\begin{gathered} y=4x-2 \\ y=4(-1)-2 \\ y=-4-2 \\ y=-6 \\ \text{Then you have the ordered pair (-1,-6)} \end{gathered}[/tex]

If x = 0

[tex]\begin{gathered} y=4x-2 \\ y=4(0)-2 \\ y=0-2 \\ y=-2 \\ \text{Then you have the ordered pair (0,-2)} \end{gathered}[/tex]

If x = 1

[tex]\begin{gathered} y=4x-2 \\ y=4(1)-2 \\ y=4-2 \\ y=2 \\ \text{Then you have the ordered pair (1,2)} \end{gathered}[/tex]

If x = 2

[tex]\begin{gathered} y=4x-2 \\ y=4(2)-2 \\ y=8-2 \\ y=6 \\ \text{Then you have the ordered pair (2,6)} \end{gathered}[/tex]

Finally, the table of the equation

and its corresponding graph will be

Therefore, the correct answer is option A.

Write an equation of the line passing through (4,-2) that is parallel to the line -3x minus 4y =5

Answers

Answer:

Step-by-step explanation:

y=4x3

Answer:

Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.

First, rearrange -3x - 4y = 5 into y = mx + c form.

-3x - 4y = 5

-4y = 3x + 5

y = -3/4x - 5/4

Since parallel lines have the same gradient, equation of line is y = -3/4x + c.

Substitute (4,-2) into the equation to find c.

-2 = -3/4(4) + c

c = 1

Hence, equation of line is y = -3/4x + 1.
