Answer:

x = 10

Step-by-step explanation:

Same as your previous question, you get x-intercept when y = 0

-2x +5y = - 20

-2x +5(0) = - 20

-2x = - 20

x = 10

Step-by-step explanation:

(X1,Y1) = (-2,2)

(X2,Y2) = (0,1)

• Find slope.

m = (Y2 - Y1)/(X2 - X1)

m = (1 - 2)/(0 - (-2))

m = -1/2

The answer is C.

Please please help!

Dimas [21]

Answer:

Step-by-step explanation:

Calculate the distance (d) using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (- 3, 9) and (x₂, y₂ ) = (3, 1)

d = $\sqrt{(3+3)^2+(1-9)^2}$

= $\sqrt{6^2+(-8)^2}$

= $\sqrt{36+64}$

$\sqrt{100}$ = 10 → C

Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using

klio [65]

Answer:

f(x) = - 3x + 4

Step-by-step explanation:

Note that y = f(x)

Given

9x + 3y = 12 ← Rearrange making y the subject

Subtract 9x from both sides

3y = - 9x + 12 ( divide all term by 3 )

y = - 3x + 4, thus

f(x) = - 3x + 4

What is the volume in cubic feet of a greenhouse that is 50 feet long, 25 feet wide, and 12 feet high?

Alexandra [31]

To find volume you just multiply the length, width, and height, so 15,000 cubic feet.
