Using substitution:
13(y+6)-6y=22
13y+78-6y=22
7y+78=22
/// -78 -78
7y=-56
÷7 ÷7
y=-8
x=y+6
x=-8+6
x=-2
So, x equals -2 and y equals -8.
Determine the base of right triangle by using pythagoras theorem.
Determine the area of base of figure.
Determine the volume of the figure.

Answer:
- Step 3.
- not switch the variables.
Step-by-step explanation:
Tom wanted to find the inverse of f(x)= 4x - 2 using the steps in the attached image.
Tom's first mistake was in Step 3.
To correct the mistake, he should not switch the variables.
The correct procedure is:
Step 1
: Given
f(x) = 4x - 2
Step 2
: Change f(x) to y
y = 4x - 2
Step 3
: Add 2 to both sides
Step 4: Divide each side by 4
Step 5: Change x to
Answer:
The median would change the most
Step-by-step explanation:
The mode will not change, because the only duplicate number is 20
The mean will change from 53.22 to 55.2 when you put 73 into the set
and the median will change from 67 to 70 when you put 73 into it
