Step-by-step explanation:
Step 1: Define
9m - m + 3 = -2(m + 1)
Step 2: Solve for m
Combine like terms: 8m + 3 = -2(m + 1)Distribute -2: 8m + 3 = -2m - 2Add 2m on both sides: 10m + 3 = -2Isolate m term: 10m = -5Isolate m: m = -1/2Gemma earns $575 a week plus $180 commission for each car she sells. She earned
$1835 last week. How many cars did she sell?
O She sold 6 cars.
O She sold 7 cars.
O She sold 8 cars.
O She sold 9 cars.
Answer:
7 cars
Step-by-step explanation:
Gemma earns $575 a week plus $180 in commission for each car sold
She earned $1835 last week
Therefore the amount of cars sold can be calculated as follows
= $575 + $180(7)
= $575 + $1260
= $1835

The inverse of function of f(x) will be p(x) = 7x – 2. Then the correct option is B.
What is inverse of a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
Let the function will be
f: X → Y
Then the inverse function will be
f⁻¹: Y → X
The function is given below.
f(x) = (x + 2) / 7
Substitute p(x) in place of x and x in place of f(x). Then the equation of the inverse function will be
x = [p(x) + 2] / 7
Solve the equation for p(x), then the equation of the inverse function will be
p(x) + 2 = 7x
p(x) = 7x – 2
Thus, the inverse of function of f(x) will be p(x) = 7x – 2.
Then the correct option is B.

HEB sells mangos for $2.50 each. Costco Sells them for $1.75 each but has a
membership fee of $50. How many mangos would you need to buy to have the 2 costs
equal each other?
Answer:
$20.833
Step-by-step explanation:
HEB:
Total cost = 2.50m
Costco:
Total cost = 50 + 1.75m
Where,
m = number of mangoes
HEB = Costco
2.50m = 50 + 1.75m
2.50m - 1.75m = 50
O.75m = 50
m = 50 / 0.75
= $20.833

Simplify by using the distributive property, then combining like terms: 3(8n - 1) - 17n
Answer:
7n - 3Step-by-step explanation:
3(8n - 1) - 17n
24n - 3 - 17n
7n - 3
Start by multiplying 3 to both values in the parenthesis.
3(8n - 1) - 17n > 8n(3) - 1(3) - 17n > 24n - 3 - 17n
Next, combine like terms.
24n - 3 - 17n > 24n - 17n - 3 > 24n - 17n - 3 > 7n - 3
Because of the variable, n, you cannot simplify any further. This means your final answer is 7n - 3 :)

Choose a method (Elimination or Substitution) to solve the system of equations. Solve and explain your process.
Answer:
(x , y) = (1/22 , 4/11)
Step-by-step explanation:
{2x - 3y = -1
{15x (-2x) + y = -1 you write as a system of equations and then you simplify the expression which would be
{2x - 3y = -1
{- 30x + y = -1 and then you multiple both sides by 15 30x - 45y = 15 { -30x +y = -1 then you divide noth sides of the equation and then you substitute the vaul of y then you solve the equation check the solution nd then get your answer
