Which equation best represents the line that is parallel to 3x -4y=7 and passes through the point (-4,-2)? Select two options.
katovenus [111]

Answer:

The equation that best represents the line that is parallel to 3x - 4y = 7 and passes through the point (-4, -2)  is y = 3/4x + 1.

Step-by-step explanation:

3x - 4y = 7 and (-4, -2)

First, solve for y in the equation:

3x - 4y = 7

-4y = -3x + 7

4y = 3x - 7

y = 3/4x - 7/4

m = 3/4 (This will be the slope of the parallel line.) and (-4, -2)

Use the point-slope equation to find the equation that will best represent a parallel line:

y − y1 = m(x − x1)

y - -2 = 3/4(x - -4)

y + 2 = 3/4x + 3 (the 4s cancel out)

(3/4 x 4/1 = 3)

y = 3/4x + 1

The graph that I attached is what these two equations would look like graphed. I am not sure what you mean by two options, I'm sorry!

Lilit [14]

Answer:

x^2 -81

Step-by-step explanation:

(x+9)(x-9)

FOIL

first x*x = x^2

outer -9x

inner 9x

last -9*9 = -81

Add them together

x^2 -9x+9x -81

Combine like terms

x^2 -81

The hypotenuse of a right triangle is 37 millimeters long. One leg of the right triangle is 12 millimeters long. What is the len
Anna35 [415]
For a right triangle. if the legs are length a and b and hypotonse is c then
a²+b²=c²

given
a lig is 12
hypotonse is 37

a=12
c=37

12²+b²=37²
144+b²=1369
minus 144 both sides
b^2=1225
sqrt both sides
b=35


the other leg is 35 mm
