Answer:
= 18
Step-by-step explanation:
= 
Cross multiply
5 * c = 30 * 3
5c = 90
Divide both sides by 5
c = 90/5
c = 18
Answer:
No solutions
Step-by-step explanation:
4(x + 3) - 4 = 8x + 10 - 4x
4x + 12 - 4 = 8x + 10 - 4x
4x + 8 = 4x + 10
4x = 4x + 2
0 ≠ 2
Best of Luck!

Answer:</h3>
- d. The y-intercept is 1 space higher.
- a. 9 to the power of -1/2
<h3>
Step-by-step explanation:</h3>
1. Changing f(x) to f(x) + 1 adds 1 to every output value of the function, moving that value "1 space higher". This is true for the y-intercept, too.
___
2. The rules of exponents apply:
- a^b · a^c = a^(b+c)
- 1/a^b = a^-b
You apparently want to simplify ...
... 9^(1/4) × 9^(1/2) / 9^(5/4)
... = 9^(1/4 + 1/2 - 5/4)
... = 9^((1+2-5)/4)
... = 9^(-2/4) = 9^(-1/2)
Answer:
$283
Step-by-step explanation:
Let,
x - for $2 notes
x + 16 - for $5 notes
EQUATION:
(x) + (x + 16) = 74
2x = 74 - 16
2x = 58
x = 29
SUBSTITUTE
x = 29 pieces of $2 notes
x + 16 = 29 + 16 = 45 pieces of $5 notes
TOTAL VALUE IS:
(29 x $2) + (45 x $5) = $283
Answer:
x = 94
Step-by-step explanation:
(86 + x)/2 = 90
86 + x = 180
x = 94
