Answer:
Oh Hi There!
Here’s ur answer!
These are the following steps to solve by substitution :-
1] Step One→ Solve one equation for either x or y.
2] Step Two→ Substitute the expression from step one into the 2nd equation.
3] Step Three→ Solve the second equation for the given variable.
4] Step Four→ Plug you solution back into the first equation.
5] Step Five→ Write your solution as a point.

Answer:
132
Step-by-step explanation:
Find Radius (r)
42/2 = 21
Plug 21 into Circumference Equation
2πr (In this case, π is 22/7)
Simplify
42 (22/7)
<u>132</u>
Answer:
y = 1/3x + 8
Step-by-step explanation:
*perpendicular means the reciprocal slope of the given line
m = 1/3
y = 1/3x + b
*plug in points with the point-slope equation
10 = 1/3(6) + b
10 = 2 + b
b = 8
*now plug everything into the equation
y = 1/3x + 8
24 + 3x = 3x + 3(7 - 1)
Eliminate the parentheses: 24 + 3x = 3x + 3(6)
24 + 3x = 3x + 18
Subtract 3x from each side: <em>24 = 18</em>
Look at that for a second. Can ANY value of 'x' make 24 equal to 18 ?
I don't think so.
There's NO number that makes the equation a true statement.
That's just another way to say: "The equation has NO solution."
