Answer:
x=5
Step-by-step explanation:
If the equation is:
3(x+1)=7(x-2) -3
Solution:
Multiply (x+1) by 3 and (x-2) by 7
3x+3 = 7x-14 -3
3x+3 = 7x -17
Now combine the like terms:
3+17 = 7x-3x
20 = 4x
Now divide both the terms by 4
20/4 = 4x/4
5 = x
You can write it as x=5
Thus the value of x is 5 ....
Answer:
For y=3x-4
x is -3 |||| y is -13
x is 0 |||| y is -4
x is 1 |||| y is -1
x is 3 |||| y is 5
x is 6 |||| y is 14
For y=-2x+11
x is -3 |||| y is 17
x is 0 |||| y is 11
x is 1 |||| y is 9
x is 3 |||| y is 5
x is 6 |||| y is -1
Step-by-step explanation:
So basically, you just substitute the x in the equations with the number on the left side.
Hope this makes sense! And I hope I wasn't too late!
If he is only buying one of each, then his total cost from each store would be:
John's: $23.89 + $15.67 + $9.99 = $49.55
Sam's: $21.35 + $12.45 + $12.99 = $46.79
So, Sam's has the better deal (proof above).
If he has 3 twenty dollar bills, then he has $60.
His change would be:
$60 - $46.79 = $13.21
If he bought two pants from Sam's (the store with the better deal), then his total would be:

(2)($21.35) + $12.45 + $12.99 = $68.14</span>

A is the correct answer. Hope this helps!
Answer:
A
Step-by-step explanation:
It will be -x^2 because the parabola if facing downward. It is -4 because -4 is the y intercept.
