The answer is 9 because 9x9=81. Hope this helps!
Answer:
$420/5
$85 a day is Jesse's daily wage
Step-by-step explanation:
1. Subtract 15 to the other side (5x^2 = 36)
2.Square root both sides to remove the squared of 5x^2 (sqrt(5x^2) = sqrt(36) simplified to 5x = 6)
3. divide by 5 to get x = 6/5
Final result is 6/5
We will use a method of substitution.
y = 5/2 x + 2
2 y = 5 x + 4 ⇒ 2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0 ⇒ x, y ∈ R
Answer: D)
This system has infinitely many solutions.
Answer:
x = -1
Step-by-step explanation:
Subtract 3 from both sides:
6x = 2x - 4
Subtract 2x from both sides:
4x = -4
Divide both sides by 4:
x = -1
(by the way, this is an equation, not an inequality - equations use =, inequalities use < > ≤ ≥)
