Question

1. Which ordered pair is a solution of the equation
y = −11x + 4?
a. (0, -7)
b. (-1, -7)
c. (1, -7)
d. (2, 26)
MY ANSWER: C
Because (X,Y)
so -11x = -11 * 1 = -11
-11 + 4 = -7


2. A plumber charges $65 per hour to fix a leak. What
is an equation that relates the total cost of a leak
repair c to the number of hours, h, it takes the
plumber to fix the leak?

MY ANSWER: c = 65h
In this equation, c represents the total cost. 65 is the price charged per hour to fix a leak. So, if I were to say it took a plumber two hours to fix a leak then my equation would be:

c = 65(2)
c = 130

Thus, the cost is $130.



3. Solve for x:
3(2x − 5) = 4x + 33

6x - 15 = 4x + 33. That will be your equation after distributing 3 through the parenthesis. Then, from there combine like terms. Add 15 to the other side. 6x = 4x + 48. Then, move 4x to the other side by subtracting it from both sides. Now, your equation will be 2x = 48. Solve for x by dividing two on both sides. x = 24.

X = 24



4. Solve for x (literal equations):
c = b – bx

MY ANSWER: c = b - bx

c = b(1-x)

c/b = 1 - x

c/b - 1 = -x

-c/b + 1 = x

This equation is read as: negative c over b plus 1 equals x

Answer 1

all correct.

Answer 2

Thank You, for these problems. I am in online school and the work is difficult sometimes. But I do have 1 question; are those options for number 4, or are they the work???


Thank You So Much,

Answer 3

Is x = 1 a solution for
the equation:
- 11x
- 4>-15
