5(5a+3)=14a-29
5(5a)+5(3)=14a-29
25a+15=14a-29
-14a -14a
11a+15=-29
-15 -15
11a=-44
11a/11=-44/11
a=-4

5(5a+3)=14a-29 -- expand brackets
25a+15=14a-29 -- subtract 15 and subtract 14a from both sides
11a=-44 -- divide by 11

a=-4

Choose the equation that satisfies the data in the table.

Zanzabum

Answer:

B. y = $\frac{2}{15} X + 2$

Step-by-step explanation:

I. Given x = 15 and y = 4

4 = $\frac{2}{15}(15) + 2$

4 = 2+2

4 = 4 true

II. Give x = 0 and y = 2

2 = $\frac{2}{15}(0) + 2$

2 = 0 + 2

2 = 2 true

III. Given x = -15 and y = 0

0 = $\frac{2}{15}(-15) + 2$

0 = -2 + 2

0 = 0 true

Good luck.
