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.
If f(x)=-3x+3, then f^-1 (x)=____
Please help
Answers
Answer:
y = (-x/3) +1 or y = (-1/3 * x) + 1
Step-by-step explanation:
For the inverse of a function, you invert the y and x positions.
In your case:
y = -3x+3
The inverted function is:
x = -3y+3
When you solve this for y, you get:
-3y = x-3
y = -x/3 +1

Sarah works for a maximum of 40 hours per week. She needs to make at least $400 in order to cover her expenses. Her office job pays
$12 per hour and her babysitting job pays $10 per hour.
Which system of inequalities can be used to determine the number of hours she should spend working in office (x) and the number of
hours she should spend babysitting (/) to cover her expenses?
Answers
Answer:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0
Step-by-step explanation:
System of Inequalities
In order to model the situation stated in the problem, we'll call the following variables:
x = number of hours Sarah spends in the office
y = number of hours Sarah spends babysitting
She works for a maximum of 40 hours per week. This condition leads us to the inequality:
x + y ≤ 40
Her office job pays $12 per hour and her babysitting job pays $10 per hour.
She needs to make at least $400 per week in order to cover her expenses, thus:
10x + 12 y ≥ 400
Two obvious conditions could be added to the set of inequalities:
x ≥ 0
y ≥ 0
The system of inequalities is:
x + y ≤ 40
10x + 12 y ≥ 400
x ≥ 0
y ≥ 0

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

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
