Answer:

y=4x-5

Step-by-step explanation:

Slope-intercept form is y=mx+b where m is the slope and b is the y intercept.

Plug in what you know to solve for b.

3 = 4(2) + b

3 = 8 + b

3-8 = b

b = -5

now put b and m back into the slope- int form.

y = 4x-5

Y = 4x - 5, the y intercept is -5

Two Dimensional Nets and Surface Area - Quiz - Level

Virty [35]

Answer:

$18\ ft^2$

Step-by-step explanation:

The complete question in the attached figure

we know that

The surface area of a cube is equal to the area of its 6 squares faces

The area of one square face is equal to

$A=b^2$

where

b is the length side of the square

we have

$b=1\ ft$

substitute

$A=(1)^2=1\ ft^2$ ---> area of one square face

Find the surface area of three cubes

Multiply the area of one square face by 6 (one cube has 6 faces) and then multiply the result by 3 (3 cubes)

$SA=3[6(1)]=18\ ft^2$
