We have from Thales theorem that because the 2 triangles are similar, JM/JK=JN/JL. We have that JN=x, JL=x+24 and that JM=7 and JK=28. Substituting, we get:
x/(x+24)=7/28.
Hence, x/(x+24)=1/4. This leads to 4x=x+24, 3x=24, x=8. We have solved for x=JN and this is equal to 8.

Answer:

B)Only one graph intersects the y-axis above y=0

Both functions are in y=mx+b. The y-intercept  is b.

f(x) has the y-intercept 3. It intersects above y=0.

g(x) has the y-intercept -4. It intersects below y=0.

This means B is correct.

Solve the system below, choose the x and y answers from the list below.
Bumek [7]

Answer:

y=2, x=-1

Step-by-step explanation:

We can add the two equations together to eliminate x:

6x+5y+(-6x)+7y=4+20

12y=24

y=2

We plug y into the first equation and get

6x+5(2)=4

6x+10=4

6x=-6

x=-1
