A. (f-g)(x) = -5^x + 3x -2
B. (f-g)(x) =5^x -3x+2
C. (f-g)(x) = -2x-2
D. (f-g)(x) = -5^x-3x-6

Answer 1

Answer:

  A.  (f-g)(x) = -5^x +3x -2

Step-by-step explanation:

The only terms that can be combined are the constants.

  (f -g)(x) = f(x) -g(x)

  (f -g)(x) = (-5^x -4) -(-3x -2) = -5^x -4 +3x +2

  (f -g)(x) = -5x^4 +3x -2 . . . . . matches A

what is the growth factor of y=1.5(0.5)^x ?

Answers

Answer:

Growth factor = 5

Step-by-step explanation:

Given

[tex]y = 1.5(0.5)^x[/tex]

Required

Determine the growth factor

An exponential function is represented as: [tex]y = ab^x[/tex]

Where b is the growth factor

By comparing: [tex]y = ab^x[/tex] to [tex]y = 1.5(0.5)^x[/tex]

[tex]b = 0.5[/tex]

Hence, the growth factor is 5

Isaiah's regular hourly rate is $12.50. When he works overtime he receives an hourly rate of 1½times his
regular hourly rate. What is Isaiah's hourly overtime rate?

Answers

$18.25 is the hourly rate because half of $12.50 is $6.25 and if you add that you will get the hourly range which is $18.25.So 18.25 is 1 and 1/2 of $12.50.

Jinan has $25 dollars to spend on drinks for
the class party. A case of drinks cost $2.50.
Create an inequality to represent the
relationship between the amount of money
Jinan has and how many cases of drinks she
can buy.

Answers

Answer:

$2.50X > $25

Step-by-step explanation:

the cost times the unknown will be less or equal to$25

The inequality function to  represent the relationship between the amount of money should be considered as the $2.50X > $25.

Calculation of the inequality function:

Since

Jinan has $25 dollars to spend on drinks for the class party.

And, A case of drinks cost $2.50.

So here the inequality function should be $2.50X > $25

Here the cost should be less or equivalent to 25.

Students in the fifth-grade class bought 28 yards of fabric to make pennants for a pep rally.
Each pennant requires 13 yard of fabric.
If the students have already made 35 pennants from the fabric, how many more pennants can they still make?
A. 63 pennants
B. 49 pennants
C. 21 pennants
D. 7 pennants

Answers

Answer:

C. 21 pennants

Step-by-step explanation:

35-28=7

7 divided by 1/3= 21/1 or 21

The number of pennants that can be made is given by equation A = 49 pennants

What do you mean by an Equation?

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of pennants required be represented as A

The amount of fabric bought by students = 28 yards

The amount of fabric required by each pennant = 1/3 yards

The total number of pennants made by students = 35 pennants

So , the number of pennants that can be made is N

N ( 1 / 3 ) = 28 be equation (1)

Multiply by 3 on both sides , we get

N = 84 pennants

So , the remaining number of pennants A = N - number of pennants made by students

On simplifying the equation , we get

The remaining number of pennants A = 84 - 45

The remaining number of pennants A = 49 pennants

Hence , the number of pennants is 49

David wants to donate $400 to a charity. He has already saved $125. He earns $9 each day at his after-school job. What is the least number of days that David must work to earn $400?

Answers

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.
