Wanda is a cake designer with a specialty in rectangular silk screen photo cakes. For every cake that she makes, the width of the cake is 4 inches more than the width of the photo in the center of the cake, and the length of every cake is two times its width. The area of the cake Wanda is currently working on is at least 254 square inches. If x represents the width of the photo, which inequality represents this situation? A) 8x^2+64x+128 ≥ 254 B) x^2+8x+16 ≥ 254 C) 2x^2+16x+32 ≥ 254 D)X^2+4x ≥ 254

answer: b.

step-by-step explanation:

it is b. cause the equations are put in the right category

to plot points   for x just start at the origin (middle) and go to the left however many times it say(if the number is a positive) if the number is a negative then go right however many times it says if it is 0 go nowhere

now keep you pencil there and go up however many times it says on y(if it is positive) if it is negative then go down however many times it says. if it says 0 go nowhere.

you have just plotted a point! now when you finish plotting all of them connect them with a ruler

plot each point as (-3, 7), (0,4), (3,1), (8,-4)   in the parenthesis on the left of the comma is x and the right is y.

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1
