Answer:
C. x = -1 ; x ~8.1
Step-by-step explanation:
First we graph 
Here we have x+2 under the square root. x+2>=0, x>=-2
So we take some x values greater than -2 and find out f(x) to make a table for graphing
x f(x)
-2 
-1 -4
2 -5
Graph it and extent the graph
Now we graph 
Given equation is in the form of g(x) = a|x-h| + k
where (h,k) is the vertex
here h= 3 and k = 4, so vertex is (3,4)
Now make a table, pick some numbers for x less than and greater than vertex
x y
-1 
0 
3 4
6 -2
Both graphs are attached below
The graph of f(x) and g(x) interests at x= -1 and x=8.1

Answer:a) 9 x t
b) x - 1/2c
c) m + 7.1
Step-by-step explanation:
STEP 1
Giving the algebraic expression becomes
A- The product of 9 and a number t. = 9 X t
B. The difference of a number x and 1/2 c= x - 1/2 c
C. The sum of a number m and 7.1 = m + 7.1
Step 2
The answers are
a) 9 x t
b) x - 1/2c
c) m + 7.1
Answer:
Step-by-step explanation:
y = total cost of gas
x = gallons of gas
(a)
y = 1.60x
(b)
y = 1.60x
32.00 = 1.60x
32.00 / 1.60 = 1.60x / 1.60
32.00 / 1.60 = x
20 = x
x = 20
Trevor bought 20 gallons of gas.
Answer:
- 85 flashlights
- 17 sleeping bags
Step-by-step explanation:
One group of 5 flashlights and 1 sleeping bag will cost ...
$12×5 +45 = $105
The total cost of the order is $1785/$105 = 17 times that amount, so there were ...
17 sleeping bags ordered
17×5 = 85 flashlights ordered
