f() = -8
Answer:
f(1) = -8
Step-by-step explanation:
Apparently, you want the argument of the function such that the function value is -8. Fill in the given information and solve for x:
-8 = -7x -1
-7 = -7x . . . . add 1
1 = x . . . . . . . divide by -7
Now, you know that ...
f(1) = -8
y = x + 1/5
y = 1/5x
y = 5x
Answer:
y = 1/5x
Step-by-step explanation:
quickly enter 0 1 2 3 4 5 for x
see what you get for y
for y = 1/5x you get the SAME number whenever you do y divided by x
x y

The equation that represents a proportional relationship with a constant of proportionality equal to 1/5 is:
y = 1/5x
A proportional relationship between two variables x and y can be written as:
y = kx
Where k is the constant of proportionality.
If k = 1/5, then the equation becomes:
y = (1/5)x
Which is the same as:
y = 1/5x
So out of the given options, y = 1/5x is the only equation that represents a proportional relationship with a constant of proportionality equal to 1/5.
The other equations have different constants of proportionality:
- y = x - 1/5 -> k = 1
- y = x + 1/5 -> k = 1
- y = 5x -> k = 5
Therefore, y = 1/5x is the correct equation with a constant of proportionality equal to 1/5.
Answer:
$74.68
Step-by-step explanation:
Convert the percent to a decimal.
4% = 0.04
Multiply his income by the percentage to find the tax.
$1,867 × 0.04 = $74.68
He can expect to pay $74.68.

Answer:
The correct option is b.
Step-by-step explanation:
It is given that the school bus has 25 seats, with 5 rows of 5 seats.
The number of students from the first grade is 15 and the number students from the second grade is 5.
The formula to arrange r items in n places is
The number of seats in first row is 5 and the number students from the second grade is 5. So, the total number of arrangement is
The number of seats except first row is 20 and the number students from the first grade is 15. So, the total number of arrangement is
The total number of ways the students can be seated if all of the second-grade students occupy the first row is
Therefore the correct option is b.
