Answer:
x = 0
Step-by-step explanation:
Step 1: Write equation
9x - 7 = -7
Step 2: Solve for <em>x</em>
- Add 7 to both sides: 9x = 0
- Divide both sides by 9: x = 0
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
9(0) - 7 = -7
0 - 7 = -7
-7 = -7
Answer:
14+6x=13, or further 1+6x=0
Step-by-step explanation:
2+3(2x+4)=13,
Distribute the 3 into the parenthesis:
2+6x+12=13
Now combine like terms: 14+6x=13.
You can also write this as 1+6x=0 by subtracting 13 to the left, though it might not be necessary.

Answer:
B. 585
Step-by-step explanation:
A graph of the scatter plot and line of best fit is attached.
The temperature in this problem will be the independent variable, or x. This is because we are assuming that the number of ice cream cones sold depends on the temperature; this means the number of ice cream cones will be the dependent variable, or y.
This means in our graphing calculator, we will enter temperature in the first list and the number of cones in the second.
After drawing the scatter plot, we run the linear regression; we get the values for a and b in our equation, y = ax+b:
a = 5.08
b = 46.59
This gives us the equation y = 5.08x + 46.59.
Entering our temperature, 106, in for x gives us
y = 5.08(106) + 46.59 = 585.07 ≈ 585
