F (x) = 3x + 7
F (-4) =
F (2) =
Answer:
f(-4)=3(-4)+7=0
f(2)=3(2)+7=13
Answer:
Step-by-step explanation:
f(x) = 3 x+7
f(x) = 3 x + 7
f(-4) = 3*-4 + 7
f(-4) = -12 + 7
f(-4) = -5
f(x) = 3 x + 7
f(2) = 3*2+7
f(2) = 6 + 7
f(2) = 13.
:f(-4) =-5 , f(2) =13

Maria started her savings account with $105. she adds $10 to it each month, including the first month. Jana Rae started her account with $0 she adds $25 to it each month. after how many months will the girls have the same amount in their accounts? how much will they have?
Answer:
After 7 months, the girls will have the same amount in their accounts. They will have 175.
Step-by-step explanation:
Maria:
Starts with $105
Adds $10 each month
Jana Rae:
Starts with $0
Adds $25 each month
Set up an equation for both Maria and Jana.
m will represent the number of months.
Maria: 105 + 10m
Jana: 0 + 25m
You can do guess and check.
Let’s say m is equal to 6.
Subsitute m with 6 for both equations and check if they both end up having the same answer.
Maria: 105 + 10(6) = 165
Jana: 0 + 25(6) = 150
Is 165 and 150 equivalent? No
Let’s try m = 7 and do that same thing.
Maria: 105 + 10(7) = 175
Jana: 0 + 25(7) = 175
Now is the answer equal? Yes
So therefore, after 7 months, the girls will have the same amount in their accounts. They will have 175.

Rewrite the equation in Ax+By=C form.
Use integers for A, B, and C.
y+ 6 = 5(x-3)
Answer:
5x - y = 21
Step-by-step explanation:
Given the linear equation in point-slope form, y + 6 = 5(x - 3):
In order to transform the given equation into its standard form, Ax + By = C, start by distributing 5 into the parenthesis:
y + 6 = 5(x - 3)
y + 6 = 5x - 15
Subtract 5x from both sides:
- 5x + y + 6 = 5x - 5x - 15
- 5x + y + 6 = - 15
Subtract 6 from both sides:
- 5x + y + 6 - 6 = - 15 - 6
- 5x + y = - 21
Divide both sides by -1:
[tex]\frac{-5x + y}{-1} = \frac{-21}{-1}[/tex]
5x - y = 21
Amir is making pizza dough using a base recipe. For each cup of water, Amir needs to use 2 2/3
cups of flour. For each cup of flour he uses, Amir needs to use 1 1/2
tablespoons of olive oil. If he uses 4 cups of water, how many tablespoons of olive oil will he need?
4 cups of water would need 16 tablespoons of olive oil.
Each cup of water uses 2 2/3 cups of flour, while each cup of flour he uses, Amir needs to use 1 1/2 tablespoons of olive oil. Hence for 4 cups of water:
4 cups of water = 2 2/3 cups of flour × 4 cups = 32/3 cups of flour
32/3 cups of flour = 1 1/2 tablespoons of olive oil * 32/3 = 16 tablespoons of olive oil
4 cups of water would need 16 tablespoons of olive oil.

If AM = x + 8 and MB= 6x – 2, find MB.
Answer:
10
Step-by-step explanation:
Firstly, AM=x+8
or, A=x+8-M......eqn (i)
MB=6x-2
or, B=6x-2-M......eqn (ii)
Now,
from eqn (i) and (ii)
x+8-M=6x-2-M
or, 8+2=6x-x-M+M
or, 10=5x
or, 10÷5=x
therefore, x=2
Again,
MB=6x-2
=6×2-2
=12-2
=10

Joe overheard his father complaining about having to pay $300 in interest in just one year. The simple annual interest rate was 16%. How much money did Joe’s father borrow?
Answer:
$1,875
Step-by-step explanation:
Interest = Principal x Rate x Time
Principal = amount of money borrowed
I = $300
r = 16% or .16
t = 1 (year)
300 = .16P
300/.16 = P
P = $1,875
The difference between 13 and a number is 4 more than twice the number
Answer: 3
Step-by-step explanation:
Let the number be 'a'.
Since the difference between 13 and a number is 4 more than twice the number, then 13 - a = 2a + 4
⇒ 13 - a = 2a + 4
2a + a = 13 - 4
3 a = 9
a = 3
∴ the number is 3Find the slope on the graph shown

8 x 2.90 = 23.20
8 hours of work will get an employee $23.20
If they worked 8 hours daily in a week:
7 x 23.20 = 162.40
Working 8 hours every day in a week will get them $162.4
