Answer:
15
Step-by-step explanation:
(g o h)(0) = g of h of 0 = g (h(0))
1. Find h(0)
h(0) = 0^2 - 5 which equals -5
2. Find g(-5)
g(-5) = -3 • -5 which equals 15
Answer: 15
Answer:
y = - 6
Step-by-step explanation:
Given
+ 9 = 6 ( subtract 9 from both sides )
= - 3 ( multiply both sides by 2 to clear the fraction )
y = - 6
Answer:
13b - 19
Step-by-step explanation:
Because 6b and 7b are like terms so we add them. And 19 is not a like term so we connot add them.
Answer:
x = 6
Step-by-step explanation:
Given
3x - 17 + 2x = 13 ← simplify left side
5x - 17 = 13 ( add 17 to both sides )
5x = 30 ( divide both sides by 5 )
x = 6
Try this solution:
according to the condition ∠1+∠2=180, it means that
74-x+86-2x=180, ⇒ x= -20/3
answer: -20/3
