Answer:
(g · h)(5) = -50
Step-by-step explanation:
Step 1: Define
h(x) = x - 7
g(x) = x²
Step 2: Find (g · h)(x)
(g · h)(x) = x²(x - 7)
(g · h)(x) = x³ - 7x²
Step 3: Find (g · h)(5)
(g · h)(5) = 5³ - 7(5)²
(g · h)(5) = 125 - 7(25)
(g · h)(5) = 125 - 175
(g · h)(5) = -50
Answer:
3. 8.60 units
Step-by-step explanation:
Distance from point M(-2, 4) to point N(5, -1) can be calculated using the distance formula, 
M(-2, 4) => (x1, y1)
N(5, -1) => (x2, y2)
Plug in the values into the formula





Here,
Two squares are given i.e.a and b
By the question,
a = (1/9)* b
or, b= 9*a-----------i
and a = b - 2
or, b= a + 2 -------- ii
equating eqn i and ii.
We get,
9a = a+2
or, 9a-a=2
or, 8a = 2
or, a = 1/4
answer = 1/4
Answer:
The inequality that can be used to find the number of balls he bought is: 
Solving the inequality gives us:
. He bought more than 36 balls.
Step-by-step explanation:
In order to solve this problem we first need to find the cost of each ball, because the number of balls he bought, n, multiplied by the cost of each ball must be more than $ 24. If a can with 3 tennis balls costs $ 2, then the cost of each ball is given by the division of the total cost of the can by the number of balls. We have:

Each ball costs
, then the inequality that can be used to find the number of balls he bought must be:

Solving for "n", gives us:

Answer:
A. $58.50, B. $80
Step-by-step explanation:
mark up percentage
x 100
30 x 45 = 100SP - 4500
5850 = 100SP
Store Price > therefore, $ 58.50
A. $58.50
<em>Actual Price :</em>
130 AP = 10400 - 100AP
AP > $80
B. $80
