Answer:
6
Step-by-step explanation:
Put the given point into the equation and solve for a.
f(-2) = a(-2 +3)² -4 = a -4 = 2
a = 6 . . . . . add 4
The a-value in the equation is 6.
Answer:
Step-by-step explanation:
1/3(x+6)=12
x+6=12/(1/3)
x+6=(12/1)(3/1)
x+6=36/1
x+6=36
x=36-6
x=30
Answer: 30
--------------------
12(x+1/6)=8
x+1/6=8/12
x=8/12-1/6
x=8/12-2/12
x=6/12
simplify
x=1/2
Answer: 1/2
------------------
-3(x+2)=-18
x+2=-18/-3
x+2=6
x=6-2
x=4
Answer: 4
-----------------
-3(x-2)=21
x-2=21/-3
x-2=-7
x=-7+2
x=-5
Answer: -5
-------------------
-5(4-x)=-40
4-x=-40/-5
4-x=8
x=4-8
x=-4
Answer: -4
------------------
1/4(6-x)=1/4
6-x=(1/4)/(1/4)
6-x=1
x=6-1
x=5
Answer: 5
Answer:
1001.
Step-by-step explanation:
1. if B=11*13; h=7, then
2. V=11*13*7=1001.
Answer:a
Step-by-step explanation:
a
Answer:
First rationalize the surd
(√3 +√2)(√3 - √2)/(√3 - √2)(√3 -√2)
The final answer will be 5 + 2√6
So x = 5 + 2√6
I) x + 1/x
5 + 2√6 + 1/5 + 2√6
Find the LCM
The final answer will be 10
ii) x² +1/x²
(5 + 2√6)² + 1/(5 +2√6)²
= 49 + 20√6 + 1/49 + 20√6
Find the LCM
The final answer will be 98
For i) x = 10
ii) x = 98
Hope this helps.
