Answer:
x = 0
Step-by-step explanation:
To solve this equation you would need to get x by itself on one side
1/2 (x+4)^2 - 5 = 3
1.) add 5 to both sides
1/2 (x+4)^2 = 8
2.) divide each side by 1/2
(x+4)^2 = 16
3.) find the square root of both sides
(x+4) = 4
4.) subtract 4 from both sides
x = 0
The app "Photomath" is a great way to solve problems like these and it gives a step by step explanation that might be easier to understand than mine :)
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8
Answer:
= 100
Step-by-step explanation:
The number of visitors is modeled by the expression 
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,

At m = -2, the value of the above expression is equal to 100.
Answer:
$700
