Hello
Answer:
The correct answer is B
Step-by-step explanation:
You just use the Distribuatd property to solve
You multiply 10 to all the varibles inside the parthense
Becasued y is equal to 7 you would do 10x7=70
then 10x8=80
and 70+80=150
and the answer says the primeter is 150 when y=7
Hope this helps

The simple formula for velocity is v=d/t. Velocity equals distance divided by time. 360 miles divided by 180 minutes. 360/180=2. The car travels at 2 miles per MINUTE.
Now, to change to miles per HOUR. There are 60 minutes in an hour, so 2*60=120 miles per hour.
Answer: 120 mph
Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5
The given function is:
f(x) = ax - 5
If f(4) = 15, then x = 4
Substitute x = 4 into f(x) = ax - 5
f(4) = a(4) - 5
15 = 4a - 5
Solve for a by adding 5 to both sides
15 + 5 = 4a - 5 + 5
20 = 4a
Divide both sides by 4
4a/4 = 20/4
a = 5
Given that f(x) = ax – 5 and f(4) = 15, then the value of a is 5

It doesn’t represent a function, since in a function- the x values can’t repeat,
In (-13,4) and (-13,9) the x values are the same.
The corresponding range of the domain is (11, -4, -29)
<h3>How to determine the range?</h3>
The function is given as:
5x + y = 1
Make y the subject
y = 1 - 5x
The domain is given as:
(-2,1,6)
Substitute these values in y = 1 - 5x
y = 1 - 5(-2) = 11
y = 1 - 5(1) = -4
y = 1 - 5(6) = -29
Hence, the corresponding range of the domain is (11, -4, -29)
