Answer:

  y = 1/2x -3

Step-by-step explanation:

  -1/(-2) = 1/2

The only answer choice with a slope of 1/2 is ...

  y = 1/2x -3

What is the area of the trapezoid?<br><br> B1=12<br> B2=6<br> H=4
Oliga [24]
The formula for the area of a trapezoid is 1/2 (b1 + b2) h
So, take your b1 and b2, 12 and 6, and add them together. You get 18.
Divide this by 2, and you get 9.
Now, multiply 9 by your height, which is 4.
9 x 4 = 36.
The area of the trapezoid is 36 square inches.

In the figure above AB = 4x + 6 and BC = 7x + 15. If AC = 120, find the length of segment AB.
Mrac [35]

Answer:

x = 9

Step-by-step explanation:

AB = 4x + 6 and BC = 7x + 15  AC is the sum of AB and BC

so 4x + 6 + 7x + 15 = 120 add like terms

11x + 21 = 120 subtract 21 from both sides

11x = 99 divide both sides by 11

x = 9
