The fourth answer is correct.

Whatever numbers you fill in (for x and y), in this formula, it is only correct when their sum is 4. Therefore the graph x + y = 4 is a line joining the points whose x and y coordinates add up to 4. The fourth answer is correct.

You can put the equation into standard form by subtracting x on both sides to get:

y = -x + 4

This graph has a negative 1 slope and is translated 4 units above the origin. Because the slope is -1, it will intercept the x - axis at 4 units and intercept the y - axis at 4 units as well.

The correct answer is D) It is a line joining the points whose x and y coordinates add up to 4

-3x = -3 because you would multiply one of the equations by -1 to eliminate y.

Answer:

x = 20

Length = 20ft

Width = 12ft

Step-by-step explanation:

A = 240

x^2 - 8x = 240

x^2 - 8x - 240 = 0

x^2 - 20x + 12x - 240 = 0

x(x-20) + 12(x-20) = 0

(x+12)(x-20) = 0

x = 20

x = -12 (which we discard since x is a length)

So the dimensions are 20ft and 20-8 = 12ft
