Answer:
y=4x+8
Step-by-step explanation:
Joel = j, Mark = m, Sandra = s
j + m + s = 120
m = 3j
j = 1/2 s --> s = 2j
plug in (substitute) each letter to make it in terms of only j: j + m + s = 120
j + 3j + 2j = 120
6j = 120
6j/6 = 120/6
j = 20
now plug in for the j & s equation:
s = 2j = 2(20) = 40
Therefore Sandra has 40 coins!
To make it simple make them all the same fraction
6/24 to trim 4/24 to style and she wants to work for 80/24 hours for 5 days
if each appointment she wants to take 6/24 to trim and 4/24 to style then every appointment will take 10/24 of an hour.
she wants to do 80/24 so she can do 8 appointments a day if each take 10/24
8 appointments a day 5 days a week
8x5= 40
Answer. 17<18
The sum of 3x + 14 equals 17x.
The difference between 20 - 2x equals 18x.
Therefore the equation is not equal to each other.
Answer:
The value of g(f(1)) is 84/5
Step-by-step explanation:
To find the answer to a composite function, start with the function on the inside, which is f(1). So, we input 1 into the f(x) equation and evaluate.
f(x) = 6x + 2
f(1) = 6(1) + 2
f(1) = 6 + 2
f(1) = 8
Now that we have the answer of 8, we can input that in for x in the outside function, which is g(x).
g(x) = 2x + 4/5
g(8) = 2(8) + 4/5
g(8) = 16 + 4/5
g(8) = 84/5
