Answer:
17 , 65
Step-by-step explanation:
x+ y = 82
y = 4x - 3
=====================
Put the second equation into the first.
x + 4x - 3 = 82
5x = 85
x = 85/5
x = 17
17 + y = 82
x = 82 - 17
x = 65
If y = 9x - 7, which of the following sets represents possible inputs and outputs of the
function, represented as ordered pairs?
{(7,9), (8, 10), (9, 11)}
{(0, -7), (1, 2), (-1, -16)}
{(1,9), (2,7), (3, 16)}
{(-7,0), (2, 1), (-16, -1)}
The answer is b {(0,-7), (1,2), (-1,-16)}
A) 2√3
B)3√3
C)5√2
Because radicals multiply like rational numbers
The answer is m=6. I used cross multiplication to effectively solve this question.
Answer:
D
Step-by-step explanation:
the percentage increase is found using
percent increase = 
× 100%
increase = 166 - 135 = 31, hence
percent increase = 
× 100% = 22.96 ≈ 23% → D
