Write the given equation in slope-intercept form -10x + 2y = 12

Answers

Answer:

x-intercept- (-1.2,0)

y-intercept- (0,6)

Step-by-step explanation:

To find the slope-intercept form, we have to find x and y.

First, find x. Get rid of the 2y, and the equation will look like this.

-10x=12

Now, divide both sides by -10.

12/-10=-1.2

The x-intercept would be (-1.2,0)

To find the y-intercept form, do the same thing.

Get rid of the -10x.

2y=12

Divide by 2 on both sides.

y=6

The y-intercept form would be (0,6)

Hope this helps! :D

is 26 and 65 relatively prime

Answers

No. 26 and 65 both have a common factor of 13, since 26 = 2•13 and 65 = 5•13, so GCD(26, 65) = 13 ≠ 1.

We can also arrive at this using Euclid's algorithm.

65 = 58 + 7 = 2•26 + 13

26 = 2•13 + 0

Since the last remainder is zero, the previous remainder is the GCD.

Using the inverse operations, the value of h is 54.

How to use inverse operation to solve equation?

An inverse operation can be defined as the operation that undoes what was done by the previous operation.

Therefore, the inverse operation of multiplication is division.

The equation is as follows:

19 = (h/3) - 8

Hence,

add 8 to both sides of the equation

19 = (h/3) - 8

19 + 8 = (h/3) - 8 + 8

27 = h / 3

Multiply both sides of the equation by 3

27 = h / 3

27 × 3 = h / 3 × 3

h = 54

Therefore,

h = 3

write a function to describe the following scenario. Billy wants to order business cards. there is a $20 minimum charge regardless of how many cards are purchased. on top of that, there is a charge of $0.06 per card

Answers

The function to describe the following scenario is f(x) = 0.06x + 20 if there is a $20 minimum charge.

What is a function?

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

Let x be the number of cards:

The total cost for the card is f(x)

Then f(x) can be framed as:

f(x) = 20 + 0.06x

f(x) = 0.06x + 20

Thus, the function to describe the following scenario is f(x) = 0.06x + 20 if there is a $20 minimum charge.

What is slope in plain English?

Slope and slant both refer to an elevation away from a surface or line that is generally straight and used as a reference. Slope is the verb form for an oblique vertical incline: Here, the land abruptly slopes either upward or downhill.The slope-intercept form of an equation is used to represent each time the equation of a line is stated as y = mx + b. M represents the line's slope. Additionally, the y-intercept is at a position where b is the b. (0, b). The slope and y-intercept of the equation y = 3x - 7 are, for instance, 3 and 0, respectively.

The slope of a line passing through points ( x₁ , y₁ ) ( x₂ , y₂ ) is defined as

m = y₂ - y₁/x₂ - x₁

if the x coordinates are not equal. The slope is not defined if the x

coordinates are equal because that would require dividing by zero.

here ,

( x₁ , y₁ ) = (0, 5)

( x₂ , y₂ ) = ( -12 , 2 )

m = y₂ - y₁/x₂ - x₁

m = 2 - 5/-12 - 0

m = -3/-12

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

⇒72a⁹b³-18a⁷b⁵=0 ------(1)

We have to factor in the expression,

⇒72a⁹b³-18a⁷b⁵=0

Take 18a⁷b³ as common,

⇒18a⁷b³(4a²-a²b²)=0

⇒18a⁷b³=0

⇒(4a²-a²b²)=0

⇒4a² = a²b²

⇒b²=4

⇒b=±2

Substitute the value of b in equation 1 we get,

The correct description of the graph of the inequality is:

"number line with open circle on point negative 2.2 and arrow shaded to the left"

Which graph represents the solution set of the inequality?

Here we have the inequality:

p - 3.6 < -5.8

First, we need to solve this, to do so we need to isolate the variable p in one of the sides of the inequality, we will get:

p < - 5.8 + 3.6

p < -2.2

So p is strictly smaller than -2.2, then we will have an open circle at the number -2.2 and a line or arrow that extends to the left.

So the correct option is:

"number line with open circle on point negative 2.2 and arrow shaded to the left"

The answers to all the equations are:

What do we mean by equations?The equals sign is used in mathematical equations to indicate that two expressions are equal.A mathematical statement that uses the word "equal to" between two expressions with the same value is called an equation.Using 3x + 5 as an example equals 15.Equations come in a wide variety of forms, including linear, quadratic, cubic, and others.Point-slope, standard, and slope-intercept equations are the three main types of linear equations.

So, f(x):

(A) f(x) = x + 3 when f(4)

f(x) = x + 3f(x) = 4 + 7f(x) = 7

(B) f(x) = 2x - 9 when f(5)

f(x) = 2x - 9f(x) = 2(5) - 9f(x) = 10 - 9f(x) = 1

f(x) = -6x + 2f(x) = -6(-3) + 2f(x) = 18 + 2f(x) = 20

Therefore, the answers to all the equations are:

(A) f(x) = x + 3 when f(4) ⇒ f(x) = 7(B) f(x) = 2x - 9 when f(5) ⇒ f(x) = 1(C) f(x) = -6x + 2 when f(-3) ⇒ f(x) = 20

A Type I error occurs in hypothesis testing when one is rejects the null hypothesis and the null hypothesis is true.

To reject the null hypothesis, statisticians conduct hypothesis testing. However, the process is always accompanied by the possibility of making a mistake. These are referred to as hypothesis testing errors.

Type I and Type II errors are the two mutually exclusive errors in hypothesis testing. Type II errors occur when a statistician fails to reject a false null hypothesis, whereas Type I errors occur when a statistician correctly rejects a genuine null hypothesis. So, c is the right response.

A quantity with an initial value of 200 grows continuously at a rate of 55% per day.

Answers

The value of the quantity after 420 minutes is 1.739

How to calculate the amount of the quantity?

In mathematics, the amount of the quantity can be measured with the help of the exponential function by using its standard equation. But the measured quantity should grow continuously.

According to the question, the growth of the quantity is growing continuously which illustrate the exponential function.

The given parameters are:

Initial value, a = 200; Rate, r = 55%

An exponential growth function is represented as:

y = a(1 + r)^x

Substitute the value in the equation

y = 200(1 + 55%)^x

After 1.55 minutes, x = 7 * 60

So, we have:

y = 200(1 + 55%)^(7 * 60)

Evaluate the expression

y = 1.739

Hence, the value of the quantity after 420 minutes is 1.739

The graph represents the inequality:

[tex]x<-3[/tex]

The reason we used strictly less than (<) is that the circle is not shaded. Therefore, the correct inequality has to be either the first or last.

We will simplify the inequalities to see which one is equivalent.

First Inequality:

[tex]5(4x+3)<10(2x+1)+7[/tex]

Expanding the brackets using the distributive property, we have:

[tex]\begin{gathered} 20x+15<20x+10+7_{} \\ 20x+15<20x+17 \end{gathered}[/tex]

Subtracting 20x from both sides, we have:

This is not the inequality.

Last Inequality:

Subtract 5x from both sides:

[tex]\begin{gathered} 3x+10-5x>5x+16-5x \\ -2x+10>16 \end{gathered}[/tex]

Subtract 10 from both sides:

[tex]\begin{gathered} -2x+10-10>16-10 \\ -2x>6 \end{gathered}[/tex]

Divide both sides by -2. Dividing by a negative number will reverse the sign:

[tex]\begin{gathered} \frac{-2x}{-2}>\frac{6}{-2} \\ x<-3 \end{gathered}[/tex]

Hence, this is the inequality.
