First in order to solve you need to get rid of the fraction. You can do so by multiplying to entire equation by the denominator like so...
5(5r - 1/5) = (4/5)5
25r - 1 = 4
Then to isolate the variable you need to add 1 to both sides.
25r = 5
Then you divide.
r = 5/25
Simplify.
r = 1/5

Answer: You have to use the distributive property of multiplication. You're answer would be 21x+6y.
Step-by-step explanation: 3(7x+2y) You have to take each individual number in the parentheses by three. That will get you 21x+6y.
Answer:
{ - 33, - 23, 2, 12 }
Step-by-step explanation:
Given
f(x) = 5x - 13 with domain { - 4, - 2, 3, 5 }
To obtain the range substitute the values of x from the domain into f(x)
f(- 4) = 5(- 4) - 13 = - 20 - 13 = - 33
f(- 2) = 5(- 2) - 13 = - 10 - 13 = - 23
f(3) = 5(3) - 13 = 15 - 13 = 2
f(5) = 5(5) - 13 = 25 - 13 = 12
Range is { - 33, - 23, 2, 12 }
Answer: YES
Plug in the numbers in your head.
y=3(10)+7
y=30+7
y=37 which is the y intercept
