Answer:
10???
Step-by-step explanation:
<8 ,
<7 and <8 form a linear pair
For this case, we observe that the dispersion diagram has a behavior similar to a straight line.
we observe that as the values of x increase, the values of y decrease.
Therefore, the line is of negative slope.
Answer:
Linear
option C
Answer:
x = 24
Step-by-step explanation:
The triangle is split into two similar triangles. They have the same shape but not the same size. To solve, write a proportion.

Cross multiply to solve for x.
56(x+4) = 44.8(35)
56x + 224 = 1,568
56x = 1,344
x= 24
-20+1= -19
-19/2= -9.5
Check:
-9.5x2= -19
-19-1= -20
