To get 20% higher than 30 you would write 20% as a decimal add 1 and multiply:
(1+.2)*30
1.2*30 = 36
You can write three equations in the numbers of nickels (n), dime (d), and quarters (q).
n + d + q = 23 . . . . . . . there are 23 coins total
0n +d -q = 2 . . . . . . . . .there are 2 more dimes than quarters
5n +10d +25q = 250 . .the total value is $2.50
The collection includes 11 nickels, 7 dimes, and 5 quarters.
_____
I used the matrix function of my calculator to solve these equations. You can find q by subtracting from the last equation five times the sum of the first two equations.
(5n +10d +25q) -5((n +d +q) +(d -q)) = (250) -5(23 +2)
25q = 125 . . . . . . . simplify
q = 5
From the second equation,
d = q +2 = 7
And from the first,
n = 23 -5 -7 = 11

Draw a line through the x axis at x=3 and shade in everything to the left of x=3. That is your graph.
Answer:
(x - 8)² + (y - 1)² = 36
None of the above
Step-by-step explanation:
Equation of a circle:
(x - h)² + (y - k)² = r²
(x - 8)² + (y - 1)² = 6²
(x - 8)² + (y - 1)² = 36
