Answer:
C.
x > 22
Step-by-step explanation:
Deena has already taken 126 calls
She takes 7 calls per hour ( think slope)
y = mx+b
y = 7x+126
She needs to take at least 280 calls. So what she does must be greater than 280
280 <7x+126
We need to isolate x. The first step is to subtract 126 from each side
280-126 < 7x + 126 -126
154 < 7x
Next, we divide by 7 on each side
154/7 < 7x/7
22 < x
Answer:
a) y> -5x+3
is what represents the shaded area
You'll have to start off by finding the variables. Ex:
3(x + 3) - 2(x + 3)
As you can see here, the two similar variables are x. By using the distributive property, you will get this:
3x + 9 - 2x + 6
Next, you'll want to subtract the two variables, since 2x has a - in front of it:
1x + 9 + 6
or
x + 9 + 6
Then, you want to add the two numbers without the variable:
x + 15
Your answer is x + 15.
Hopefully that helped! :)
