Remember you can do anything to an eqution as long as you do it to both sides
easy
first one
flat rate+variable rate=amount paid
flat rate=35
variable=15 times hours, so if h=hours then
and amount paied is 95
35+15h=95 is da equation
if we solve
mins 35 both sides and divide both sides by 15
h=4
2nd one
add 5 to both sides and times 4 both sides
c/4=9
c=36
3rd photo
add 6 to both sides
y+6-6≥12+6
y+0≥18
y≥18
(2x² + 6x + 10) + (4x² + 2x + 3)
Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-
= 2x^2 + 4x^2 + 6x + 2x + 10 + 3
= 6x^2 + 8x + 13 answer
Answer:
b^20/a^12
Step-by-step explanation:
b to the power of 20 over a to the power of 12
They can be equal if the absolute value of b is 1.
