Answer:
Can you like put up a pic or the equation pls??..
Step-by-step explanation:
Answer:
y = -3x+8
Step-by-step explanation:
We can use the slope intercept form of an equation
y = mx+b where m is the slope and b is the y intercept
y = -3x+b
Substitute the point into the equation
-1 = -3(3)+b
-1 = -9+b
Add 9 to each side
-1+9 = -9+9+b
8 =b
y = -3x+8
Assuming that I am properly understand your question, all you have to do is get the initial values for each individual and add their savings monthly.
Starting
Josie: 80
Addie: 60
One month
Josie: 110
Addie: 100
Two months
Josie: 140
Addie: 140
So two months would be the answer.
You could also do...
x = months
80 + 30x = 60 + 40x
20 + 30x = 40x
20 = 10x (Divide by ten on both sides)
2 = x
2 Months
Answer:
PM = 26.1
Step-by-step explanation:
If they are both similar shapes, each side must be scaled up to the same factor. To find the missing side length, you must know that the side lengths are multiplied by the exact same number. Knowing this, you can set the ratio of the side lengths equal to each other and then cross-multiply to find the missing side length.
<----- Ratio
<----- Insert side lengths
15x = 392 <----- Cross multiply
x = 26.1 <----- Divide both sides by 15
