Answer:
Ummm, so the answer is A. (-3,-2)
StepByStep Solution:
5x + 7(x+1) =-29
5x+7x+7=-29
12x=-36
x=-3
y=-3+1
y=-2
Answer:
Step-by-step explanation:
You do what's in the innermost brackets first, unless you have an unknown variable.
Answer:
x = 20
Step-by-step explanation:
19 < x < 25
x had to be higher than 19 but lower than 25
18 cant be the answer because it is less than 19
27 cant be the answer because it is higher than 25
that leaves 20, which is the right answer
19 < 20 < 25
4x - 5y = -15
y = -3x + 22
Plug in your y= equation into the y variable in the other equation
4x - 5 (y) = -15
^^
y = (-3x + 22) = -15
4x - 5 (-3x + 22) = -15
Distribute
4x + 15x - 110 = -15
Combine like terms and add 110 over to -15
19x = 95
Then, divide the whole equation by 19
x = 5
Then, plug in your x into your y= equation
y = -3 (5) + 22
y = -15 + 22
y = 7
<em><u>x = 5</u></em>
<em><u>y = 7</u></em>
<em><u>(5, 7)</u></em>
-110x+40
You need to use the distributive property for this problem
You multiply 22x times -5 (which is -110x) and -8 times -5 (which is 40) to get -110x+40
