Answer:
Step-by-step explanation:
First you need to do 5x5=25
Answer:
b(-10)= -6
Step-by-step explanation:
b(x)= |x+4|
b(-10)= |-10+4|
b(-10)= -6
|6x + 5| = 7 · 3
|6x + 5| = 21
6x + 5 = 21 (1st equation)
-6x + 5 = 21
(1st equation)
6x = 21 - 5
6x = 16
x = 8/3
(2nd equation)
-6x - 5 = 21
-6x = 21 + 5
-6x = 26
x = -13/3
so all of the solutions are;
x = -13/3, 8/3
Answer:
(x + 12) / 4
Explanation:
This was the way I was taught, hopefully it helps you.
y = 4x - 12
x = 4y - 12
x + 12 = 4y
(x + 12) / 4 = y
Answer:
y=5x+50
Step-by-step explanation:
Y= how much money in your account.
you use the formula y=mx+b to show a steady slope.
B is the Y-intercept or where your data starts.
In this case it would be $50.
You then add or deposit 5 dollars each week.
X=# of weeks.
Y = 5x + 50
You have $50, and for x amount of weeks you deposit $5
