Answer:

Richie should add the number 36 to both sides.

Step-by-step explanation:

To complete the square, you need to divide <em>b</em> by 2, square it, then add it to both sides. In this case, you'd do this:

12/2=6

6^2=36

TRANSPORTATION The cost of riding in a cab is $3.00 plus $0.75 per mile. The equation that represents this relation is y=0.75x+3
Amanda [17]

Answer:

f(17) = $15.75

The amount it takes for a trip of 17 miles is $15.75

Step-by-step explanation:

Here, we want to calculate f(17)

The equation is given as;

y = 0.75x + 3

For f(17), substitute x for 17

y = 0.75(17) + 3

y = 12.75 + 3

y = $15.75

What f(17) means is that the ride was for 17 miles

$15.75 is for a trip of 17 miles

Solve for x, with variables on both sides of equation. (Note: x is the same thing as 1x) You must show your work!
bagirrra123 [75]
Hello! We already have the equation set up, which is 9x = x + 4. Let's solve for x. Subtract x from both sides to get each side by itself x - x cancels out. 9x - x is 8x. That leaves 8x = 4. Now, divide each side by 8 to isolate the x. 8x/8 cancels out. 4/8 is 4/8 or 1/2 in cimplest form. Let's plug this value in and see if it works. 9 * 1/2 is 4 1/2. 1/2 + 4 is 4 1/2. 4 1/2 = 4 1/2. There. x = 1/2.
