3(4a+7)=5(2a+4)+1 What is it?
hichkok12 [17]

Answer:

a = 0

Step-by-step explanation:

3(4a+7)=5(2a+4)+1     Distribute 3 through the parentheses

                 - >                         12a + 21 = 5(2a + 4) +1

5(2a + 4) +1   -->  10a + 20 + 1

12a + 21 = 10a + 20 + 1  -->    12a + 21 = 10a + 21   -->      12a = 10a

                                                     12a - 10a = 0   -->    2a = 0

Divide both sides of the equation by 2      -->     a = 0

A line with a slope of -7 passes through the points (u,0) and (8,-7) what is the value of u?
laila [671]

Answer:

u = 7

Step-by-step explanation:

Using the slope intercept formula:

\frac{y2 - y1}{x2 - x1}  = slope

Substitute our values from the points and the known slope:

\frac{-7 - 0}{8 - u} = -7

Now we multiply both sides by (8 - u) to isolate the x:

(8-u) x \frac{-7}{8 - u} = -7 (8 - u)

Next we add 56 to both sides:

-7 = -56 + 7u

Finish off by dividing both sides by 7:

7u = 49

u = 7
