Answer:
f ( -2 ) = 30
g ( -2 ) = 3
Step-by-step explanation:
when it says f(x) and then has f(-2) - you fill in all x's in the equation with -2.. like this:
f(x) = -7(-2-2) +2 g(x) = 2(-2)^2 -5
f(x) = -7(-4) +2 g(x) = 2(4) -5
f(x) = 28 + 2 g(x) = 8 - 5
f(x) = 30 g(x) = 3
hope this helps!!

The statement which is true for the provided reason is the equation 3.5|6x – 2| = 3.5 has one solution.
<h3>How to find one solution of equation?</h3>
If the equation is given a unique and single value of variable after solving then the equation is said one solution equation. Such equation gives exactly one solution.
The three types of solution of an equation are-
- One solution-When the provides the singe value of the given variable, we get one or unique solution.
- No solution-When the graph of equations is equal than it provides the no solution. When the value, does not equate for the expression, then the expression has no solution.
- Infinite many solution-For the same line, the equation has the infinite many solutions.
The first equation given in the problem is,
This equation has one solution. This in not correct option.
The second equation given in the problem is,
This equation has one solution. This in correct option.
Hence, the statement which is true for the provided reason is the equation 3.5|6x – 2| = 3.5 has one solution.

Answer:
B
Step-by-step explanation:
Let x = every day he rented the kayak
Since the store charges $60 for each day, multiply x by 60 like this: 60x
They also have $25 on top of that; 60x + 25
This all has to equal $325; 60x + 25 = 325
To solve for x, subtract 25 from both sides
60x + 25 = 325
- 25 - 25
60x = 300
Divide both sides by 60
60x/60 = 300/60
x = 5
This means Tobias rented the kayak for 5 days
Answer:
10 km/h
Step-by-step explanation:
I'm not really sure about this but no ones answering your question and I wanna help.
So basically to calculate the average speed you need to divide the distance travelled by time taken
But you do not have the distance traveled. But it is mentioned that it takes u 30 minutes to walk from home to school when walking at 5 km/h so to find the distance all you have to do is... 30 x 5 = 150 km
Now that we have the time and distance all we have to do is find the average speed.
Average Speed = distance ÷ time
So 150 ÷ 15 = 10 km/h
