Answer:
D
Step-by-step explanation:
Lets start by figuring out the vertex. From looking at the picture, you can tell that the vertex (the place where the line thingy stops going down and starts going up) is (-3 , -1).
Now, these equations are set up like this: y2 = h*(x2 - x1) + y1
(-3 , -1) is the same thing as saying (x1 , y1)
So, this rules out A, B, and C
Therefore, your answer is D! :D
The area is the sum of the areas of the rectangle and triangles,
.. Area = (6 in)*(4 in +8 in) = 72 in^2
(Together, the two triangles make a rectangle 6 in high by 4 in wide.)
Answer:
Step-by-step explanation:
Solve For X.
3x(x+42)
Ans:
3x(x+42)
Use the distributive property to multiply 3x by x+42.
<span>In a system of linear equations we should first try to eliminate one variable. Like this:2a+2x=18........................(1)a+3x=17........................(2)Multiply equation (2) with 2:2a+6x=34....................(3)Subtract 1) and (3):-4x=-16x=4Substitute in 1) or 2) to get 'a' value:a=5Therefore the solution is x=4 and a=5...................(Answer)</span>
