Answer:
x = 3
Step-by-step explanation:
The smaller triangle and larger one are similar, so corresponding sides are proportional.
8/4 = (8 +(x -1))/5
10 = x +7 . . . . . . . . . multiply by 5 and simplify
3 = x . . . . . . . . . subtract 7

<em>Alternate solution</em>
The short segments are also proportional:
(x -1)/(5 -4) = 8/4
x -1 = 2 . . . . simplify
x = 3 . . . . . . add 1
Answer:
-7
Step-by-step explanation:
6x - 5 = -47 subtract 5 from both sides so the x is alone
6x = -42 divide by 6 so you can find what x equals
x= -7
First, you will plot the point.
So, your first point will be (0,3) since that is the y intercept.
The next point would be (1,6)
Then (2,9)
Now, lets get the left
Another point would be (-1,0)
Then (-2,-3)
Now that you have those points, plot them, and draw a line
All you need to do to answer this equation is to continually add 3/4 until you get 9 1/2 or as close as you can get without going over. In this case if you keep on adding 3/4 you will get only up to 9 because you cant go over your value of 9 1/2. Your answer is D.
