Answers

Answer 1

Answer:

y=2x-13

Step-by-step explanation:

According to y- y1= m( x-x1),

y-(-5)= 2 ( x-4)

So, y=2x -13

Answer 2

Step-by-step explanation:

y - 5 = 2

x - 4

y - 5 = 2x - 8

y = 2x - 8 + 5

y = 2x - 3

Answer:

NO

Step-by-step explanation:

Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if: y=kx. for some constant k . This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

also if it would be the same it would be (0,0) then (2,4) and finally (3,6) now that it would be a constant one.

5^(2x-1)+5^(x+1)=250
how do you solve?
thank you

Answers

Answer:

x = 2

Step-by-step explanation:

Exponential Equations

Solve:

[tex]5^{2x-1}+5^{x+1}=250[/tex]

Separate each exponential:

[tex]5^{2x}5^{-1}+5^{x}5^{1}=250[/tex]

Operating:

[tex]\displaystyle \frac{5^{2x}}{5}+5^{x}5=250[/tex]

Multiplying by 5:

[tex]5^{2x}+25\cdot5^x=1250[/tex]

Rearranging:

[tex]5^{2x}+25\cdot5^x-1250=0[/tex]

Recall that:

[tex]5^{2x}=(5^{x})^2[/tex]

[tex](5^{x})^2+25\cdot5^x-1250=0[/tex]

Calling

[tex]y=5^{x}:[/tex]

[tex]y^2+25y-1250=0[/tex]

Factoring:

[tex](y-25)(y+50)=0[/tex]

There are two possible solutions:

y=25

y=-50

Since

[tex]y=5^{x}[/tex]

y cannot be negative, thus:

[tex]5^{x}=25=5^2[/tex]

The solution is:

x = 2

Find the X- and y-intercepts of the graph of the equation y = 36 - 6x

Answers

Step-by-step explanation:

The x int- is -6x and the y int- is 36

Answer:

X intercept: (6,0)

Y intercept: (0, 36)

Step-by-step explanation:

X intercept: When y = 0

0 = 36 - 6x

-36 = -6x, x = 6

X intercept: (6, 0)

Y intercept: When x = 0

y = 36 - 6(0)

y = 36 - 0, y = 36

Y intercept: (0, 36)

Find the principal invested if $549 interest was earned in 8 years at an interest rate of 9%

Answers

The value of the principal invested is $762. 5

How to determine the principal amount

The formula for calculating simple interest is expressed as;

I = PRT/100

Such that the parameters of the formula are represented as;

I is the simple interest.P is the principal amount.R is the rate of the interest.T is the time in years taken.

Now, substitute the values into the equation, we have;

$549 = P × 9 × 8/100

Multiply the values

$549 = 72P/100

cross multiply the values

$549 × 100 = 72P

Multiply the values

72P = 54900

Divide both sides by the coefficient of P

P = $762. 5

Which statement about the zeros of the graphed function is true?

Answers

Answer:

A. The function has three distinct real zeros.

Step-by-step explanation:

The correct option is that the function has 3 distinct real zeros.

For a quadratic graph, the point where the curves intersect the x-axis is the x-intercept of the graph.

The zeros of the graph are the point where the curves touches the x-axis. From the given graph, we can see that the curve cuts the x-axis at three points at, x = 1, x = 4 and x = 6.

Since the values are real and distinct, hence the correct option is that the function has 3 distinct real zeros.

At the Foremost State Bank the average savings account balance in 2012 was $1900. A random sample of 45 savings account balanes for 2013 yielded a mean of $1000 with a standard deviation of $225. At the α = 0.01 significance level test the claim that the mean savings account balance in 2013 is different from the mean savings account balance in 2012.

Answers

Answer:

The calculated  |t| = |-26.517|=26.517 > 2.326 at 0.01 level of significance

Null hypothesis is rejected at 0.01 level of significance

There is difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012

Step-by-step explanation:

Step(i):-

Mean of the Population = 1900

Given random sample size 'n' =  45

Mean of the sample x⁻ = 1000

Standard deviation of the sample = 225

Null Hypothesis:-

There is no difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012.

Alternative Hypothesis :-

There is difference between mean savings account balance in 2013 is different from the mean savings account balance in 2012

Step(ii):-

Test statistic

        [tex]t = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]

        [tex]t = \frac{1000-1900 }{\frac{225}{\sqrt{45} } }[/tex]

       t = -900 /33.54 = -26.517

      |t| = |-26.517|=26.517

Degrees of freedom

                       γ = n-1 = 45-1 =44

t₍₀.₀₁ , ₄₄₎ = 2.326

The calculated  |t| = |-26.517|=26.517 > 2.326 at 0.01 level of significance

Null hypothesis is rejected at 0.01 level of significance

Can you determine the function an equation
, the slope and y intercept I would hope you can thanks luv

Answers

Answer:

Slope = 3

y intercept = 35

Step-by-step explanation:

Given

x = time

y = letters that can not be scanned

Also, we have:

[tex](x_1,y_1) = (15,80)[/tex]

[tex](x_2,y_2) = (45,170)[/tex]

The slope is calculated as follows:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{170-80}{45-15}[/tex]

[tex]m = \frac{90}{30}[/tex]

[tex]m = 3[/tex]

To calculate the y intercept, we need to determine the linear equation using:

[tex]y - y_1= m(x-x_1)[/tex]

Substitute values for x1, y1 and m

[tex]y - 80 = 3(x - 15)[/tex]

Open bracket

[tex]y - 80 = 3x - 45[/tex]

Make y the subject

[tex]y = 3x - 45+80[/tex]

[tex]y = 3x +35[/tex]

An equation has the general form:

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

Where

[tex]b= y\ intercept[/tex]

By comparison:

[tex]b = 35[/tex]
