Answer:solve for x
-3x+5y=-15
Add -5y to both sides
-3x+5y+-5y=-15+-5y
-3x=-5y-15
Divide both sides by -3
-3x/-3=-5y-15/-3
x= 5/3 y +5
I hope that's help!

Answer:
The domain for graph 1 is all real numbers, the range is y >= 0.
The domain for graph 2 is x >= 0, the range is y >= 0
Step-by-step explanation:
Graph 1: The x values are infinite for the graph, the y values will always be above zero and continue to be infinite.
Graph 2: The x values start at 0 and go to the right for infinity, the y values start at 0 and continue to infinity.
f(-1) = -11 and f(3) = -3 . these functions are true .
What does a math function mean?
- A relationship between a group of inputs and one output each is referred to as a function.
- A function is an association between inputs in which each input is connected to precisely one output.
- A domain, codomain, or range exists for every function. f(x), where x is the input, is a common way to refer to a function.
- In mathematics, a function is an expression, rule, or law that establishes the relationship between two variables (the dependent variable).
given function f(x) = 2x - 9
f(-1) = -11 ⇒ x = -1 put in function
f( -1 ) = 2 * -1 - 9 ⇒ - 11
f(2) = 5 ⇒ x = 2 put in function
f( 2 ) = 2 * 5 - 9 = 1
f(3) = -3 ⇒ x = 3 put in function
f ( 3 ) = 2 * 3 - 9 = -3
f(-3) = 15 ⇒ x = -3 put in function
f( -3) = 2 * -3 - 9 = - 15

Answer:
(a) Equations for both
--- lifeguard
--- camp counselor
(b) Total pay for 5 days
Lifeguard pays $800
Camp counselor pays $375
(c) Which pays more
Lifeguard job pays more
Step-by-step explanation:
Let
Given
Lifeguard job
Camp counselor job
Solving (a): The equation for both
The total pay for each job is calculated as:
Total Pay = Signing Bonus + Rate * Hours
So, we have:
Lifeguard
Camp counselor
Solving (b): Total pay for 5 days
First, we calculate the total hours worked in 5 days
So, the pay for each is:
--- Lifeguard
--- camp counselor
Solving (c): Which job pays more
By comparing the solution in (b)
<em>Hence, lifeguard job pays more</em>

Step-by-step explanation:
<u>You need to find the difference:</u>
- 17.50x + 25 - (8.50x + 3) =
- 17.50x - 8.50x + 25 - 3 =
- 9x + 22
Correct one is B
