Answer:

y = 3x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 12x - 4y = - 8 into this form

Subtract 12x from both sides

- 4y = - 12x - 8 ( divide all terms by - 4 )

y = 3x + 2 ← in slope- intercept form

Hey there!

Isolate the y variable by subtracting 12x in both sides:

-4y = -12x - 8

To solve for y divide -4 in both sides

y = 3x + 2

Our answer would be <u>y = 3x + 2</u>

△HFM ~ △PST

MissTica

Answer:

The perimeter of △HFM is 50.75 units

Step-by-step explanation:

The picture of the question in the attached figure

In this problem

Triangles HFM and PST are similar

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional, and this ratio is called the scale factor

step 1

Find the scale factor

Let

z ----> the scale factor

$z=\frac{HF}{PS}$

substitute the given values

$z=\frac{14}{8}=1.75$

step 2

Find the perimeter of triangle PST

$P=8+9+12=29\ units$

step 3

Find the perimeter of triangle HFM

we know that

If two figures are similar, then the ratio of its perimeters is equal to the scale factor

The perimeter of triangle HFM is equal to the perimeter of triangle PST multiplied by the scale factor

$29(1.75)=50.75\ units$

Ber [7]

Answer:

A-B=x^2-x+1

Step-by-step explanation:

A-B=3x^2+5x-6+(-2x^2-6x+7)

=3x^2+5x-6-2x^2-6x+7

=x^2-x+1
