2ax-15=2(x+5)+5(x-1)

1 answer:

5 0

Perform the indicated multiplication:

2ax - 15 = 2x + 10 + 5x - 5

Group x terms together: 7x - 2ax = 5 - 15
x(7-2a) = - 10
-10
x = ----------
7-2a

Here, a cannot be 3.5, because the denominator 7-2a would be zero.

I need with these problems

ch4aika [34]

Answer:

1. $\frac{5}{6}$

3. $\frac{7}{0}$ (undefined slope)

5. $-\frac{7}{4}$

7. $24$

Step-by-step explanation:

slope (m)

rate of change (r)

1. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{8-3}{13-7} =\frac{5}{6}$

3. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{4-(-3)}{9-9} =\frac{7}{0}$ (undefined slope)

5. m = $\frac{y_2-y_1}{x_2-x_1}=\frac{-1-6}{0-(-4)} =\frac{-7}{4}=-\frac{7}{4}$

7. r = $\frac{f(b)-f(a)}{b-a}=\frac{24-0}{1-0}=\frac{24}{1}=24$

Hope this helps!
