Answer:
21
Step-by-step explanation:
Plug in 3 for m in the equation:
n=10x3-9
n=30-9
n=21
Answer:
Step-by-step explanation: Step 1: Simplify both sides of the equation.
3(y+8)=36
(3)(y)+(3)(8)=36(Distribute)
3y+24=36
Step 2: Subtract 24 from both sides.
3y+24−24=36−24
3y=12
Step 3: Divide both sides by 3.
3y/3=12/3
y=4
3x - 1 = 3x -1 because it's reflecting itself
Answer:
18 - (-12)
Step-by-step explanation:
Final temp. - Initial temp. = the change in temperature
By -12, we're indicating that is below zero (which is obvious) meaning that it is not in the "normal" scale nor in the imaginary scale of numbers. So, we can operate the following...
18 - (-12) = 30
So the temperature changed by 30 values or the temperature increased by 30 values, because the number is positive.
It's a flat horizontal line so the slope is 0
Slope = rise/run = 0/run = 0
The "run" can be any number you want as long as it's not 0.
