Answer:
x = a(c - b)
General Formulas and Concepts:
<u>Pre-Algebra</u>
Step-by-step explanation:
<u>Step 1: Define Equation</u>
x/a + b = c
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract <em>b</em> on both sides: x/a = c - b
- Multiply <em>a</em> on both sides: x = a(c - b)
Hey there!
No, the graph is not a function because it has two of the same inputs, (7, -6) and (7, -7).
It also can't be a linear function because the graphs are not pointed to form a straight line.
Hope this helps!
Have a great day!
Y varies directly as x: y=kx, k is a constant.
when x=7, y=21, so we know k=3
therefore, the equation is y=3x
When you multiply powers inside the parenthesis, you add them.
3+5=8
(5^8)^5
When powers are outside the parenthesis, you multiply them.
5*8= 50
5^40
Remember: you keep the constant the same. (5)
“D” is the answer.
I hope this helps!

Answer:
$127.75
500 quarters equals $125.00 (500 x 0.25 = 125)
25 dimes equals $2.50 (25 x 0.10 = 2.50)
25 pennies equals $0.25 (25 x 0.01 = 0.25)
