Solve for x
6x+5y=-15
subtract 6x from both sides
5y=-6x-15
divide both sides by 5
y=-6/5x-3
First, let's find the X Intercept
You are going to have to set y to 0
-8x + 4(0) = 24
Any time you multiple a number by 0, the answer is 0
-8x (+ 0) = 24
Now we are going to divide each side by -8
-8x/-8 = 24/-8
x = -3
Now let's find the Y Intercept
You are going to have to set x to 0 like we did with the first one
(-8(0)) + 4y = 24
4y/4 = 24/4
y = 6
Your intercept is (-3,6)
Answer:
{7, 8, 9, 10}
Step-by-step explanation:
Having worked 4 hours babysitting, Zoé has already earned 4×$7 = $28, so only needs to earn $130 -28 = $102 more.
At $15 per hour, it takes her $102/$15 = 6.8 hours to earn that amount. In order to keep her total hours to a maximum of 14, Zoé cannot work any table-clearing hours more than 14 -4 = 10. The possible solutions for Zoé's hours doing table clearing are ...
{7, 8, 9, 10} . . . . hours
_____
We have assumed Zoé must work whole numbers of hours.
Circumference of a circle =
They are all multiplied by each other
r = radius
we know our radius is 40
and...
= 3.14
so we would use this expression 3.14 x 40 x 2 As a added bonus ill solve it for you :P
3.14 x 40 x 2 = 251.2
The circumference of this ice skating rink is 251.2 feet
Answer:
J. P+7 less than or equal to 50
Step-by-step explanation:
You don't even need to look at the left side of the equation. There is a maximum of $50 you can spend so you can spend $50 or less than $50
