Since this scuba diver descends below the surface of a lake at a rate of 12 feet per minute, an integer which represents the depth of the diver after four (4) minutes is 48 feet.
What is the rate of change?The rate of change can be defined as a type of function that describes the average rate at which a quantity decreases or increases with respect to another quantity.
Mathematically, the rate of change for the depth covered by this scuba can be calculated by using this formula;
Rate of change = Depth/time
Making depth the subject of formula, we have:
Depth = Rate of change × time
Substituting the given parameters into the formula, we have;
Depth = 12 × 4
Depth = 48 feet.

For Items 16-28, determine whether each function is
even, odd, or neither.
f(x) = -x + 2x + 5
f(x) = x + 8x
f(x) = -7x² + 5
f(x) = 5x + 3x? – 7x + 1
Answer:
f(x) = -x + 2x + 5
is odd since f(x) = -5
f(x) = x + 8x
is neither because f(x) = 0
f(x) = -7x² + 5
is odd since f(x) = √5/7
f(x) = 5x + 3x? – 7x + 1
is odd

Add the fractions
4/5 +1/3
The LCD is 15
12/15 + 5/15
17/15
Simplify
17/15 = 1 2/15
1 is a while number so, add it to the other whole number

Chad has a bag with 2 mint sticks, 11 jelly treats, and 7 fruit tart chews. If he eats one piece every 4 minutes, what is the probability his first two pieces will be a jelly treat and a mint stick and represent as a percent to the nearest tenth if necessary?
Answer:
first you add all the candies together to get 20 in the bag
2+11+7=20
jelly treat:
now we divide 11 by 20 to get a decimal
11/20= .55
multiply .55 by 100 to change it to a percentage
.55*100=55
first part of answer: He has a 55% chance of getting a jelly treat
mint stick:
divide 2 by 20 to get a decimal
2/20=.1
change .1 to a percent by multiplying by 100
.1*100=10
second part of answer: he has a 10% chance of getting a mint stick

In the figure, angle E measures 54° and angle G measures 29°. What is the measurement of angle H?
A.
25°
B.
34°
C.
97°
D.
126°
Answer:
H=97 degrees or choice "C"
Step-by-step explanation:
Assuming this is a triangle:
All triangles contain 180 degrees, so:
180=E+G+H, or H=180-E-G
H=180-54-29
H=97
H=97 degrees or choice "C"

find the additive inverse of-9x+3
Answer:
9x − 3
Step-by-step explanation:
−9x + 3 = −1(−9x + 3) Multiply the expression by −1.
−1(−9x) + −1(3) Distributive Property
9x − 3 Simplify.
The additive inverse of the given expression is 9x-3.
The given expression is -9x+3.
What is additive inverse?The additive inverse of a number is its opposite number. If a number is added to its additive inverse, the sum of both the numbers becomes zero. The simple rule is to change the positive number to a negative number and vice versa.
The additive inverse of the expression is -(expression).
Now, -(-9x+3)
= 9x-3
Therefore, the additive inverse of the given expression is 9x-3.

Complete and solve the equation that can be solved to find the number of hours for which the total cost
will be the same for the two services. In your equation, use x to represent the number of hours of dog
sitting
The equation is
The total cost will be the same for the two services at
hours.
Answer: both services will cost the same if it is for 3 hours service.
Step-by-step explanation: Hope this helps.
Define x: Let x be the number of hours
Derrick Dogs sitting:
Fixed charged=$12
Hourly change=$5
Total charge=12+5x
Darlene dog sitting:
Fixed charged=$18
Hourly change=$3
Total charge= 18+3x
Find the total number of hours so that both cost are the same:
12 + 5x = 18 + 3x
5x - 3x = 18 - 12
2x = 6
x = 3
