x= c-by/a <------ divide by a

Step-by-step explanation:

-3^2 / 9^6

-3^2 / 3^2

(9 divided by 3 = 3 and 6 divided by 3 = 2)

It would now be -1 because a negative divided by a positive gives a negative.

Answer:

the answer is c

Step-by-step explanation:

The x values get larger when you move (x, y) to right side. Therefore, option A is the correct answer.

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Here,

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When you move the ordered pair (x, y) to right, x value gets increased.

Therefore, option A is the correct answer.

It's the only line with a curve.

I believe it's negative thirty six or -36

The slope of lien is 3/4

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as

m = Δy/Δx

where, m is the slope

Note that tan θ = Δy/Δx

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane. Calculating the slope of a line is similar to finding the slope between two different points. In general, to find the slope of a line, we need to have the values of any two different coordinates on the line.

According to given graph,

Take the co-ordinate (1, 6) and (5, 9)

slope= 9- 6/ 5-1

m=  3/4

Answer:

The required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Step-by-step explanation:

In this question we need to find the equation of the graph in factored form.

The factored form will be: [tex]f(x)=a(x-r_1)(x-r_2)..[/tex]

where a is y-intercept and r₁, r₂ are x-intercepts

X-intercepts

When y=0, the values of x axis are known as x-intercepts

Y-intercepts

When x=0, the values of y-axis are known as y-intercepts.

Looking at the graph finding x-intercepts

When y=0 x=-2 and 1

So, we have

r₁ = -2

r₂ = 1

Looking at the graph finding y-intercepts

When x=0, y=-4

So, a = -4

Putting values in the formula we will get:

[tex]f(x)=a(x-r_1)(x-r_2)\\f(x)=-4(x-(-2))(x-1)\\f(x)=-4(x+2)(x-1)[/tex]

So, the required equation in factored form is: [tex]\mathbf{y=-4(x+2)(x-1)}[/tex]

Answer:

18

Step-by-step explanation:

Solve the separate part of the equation first

6(4) 6(-2) would equal 24-12

Add it back in to get: 10 - 4 + 24 - 12

-4-12 and 10+24 are the like terms so

10+24 = 34 and -4-12 = -16

Equation in the end: 34-16

Simplify that to: 34-16 = 18

Answer:

3 cupcakes

Step-by-step explanation:

to figure it out you could've done 15*0.20

use that equation for future percentage problems

amount x percentage in the form of a decimal

First, find the discount by finding 10% of $14.58. To do this, convert 0% into a decimal and multiply by $14.58.

14.58 x 0.1 = 1.458.

Since this a sale price, how much he is getting off, subtract from the total.

14.58 - 1.458 = 13.122.

We still have to find the sales tax. Solving is similar to finding the discount.

13.122 x 0.0825 = 1.082565.

Now, since it is a tax, add to the total.

13.122 + 1.082565 = 14.204565

Round to the nearest hundredth, and you have $14.20.

The sale price with after tax is $14.20.
