Answer:
Step-by-step explanation:
You cannot add these because they are not like. IF you have a value for x, then the expression could be evaluated at the x value, but you can't add them.
Answer:
Graph is option A
Step-by-step explanation:
3x + 5y = –15
To graph the equation , we need to get y alone

Subtract 3x on both sides

Divide whole equation by 5

To graph this equation , we need to make a table
Plug in some number for x and find out y
x 
0 -3
-5 0
Two points on the graph is (-5,0) and (0,-3)
Graph is option A
Answer:
D
Step-by-step explanation:
x/(x²+3x+2) - 1/[(x+2)(x+1)]
x² + 3x + 2 = x² + 2x + x + 2
= x(x + 2) + (x + 2)
= (x + 2)(x + 1)
= x/[(x+2)(x+1)] - 1/[(x+2)(x+1)]
= (x-1)/[(x+2)(x+1)]
= (x-1)/(x²+3x+2)
Answer:
65 cents
Step-by-step explanation:
divide 10 by 2.25 to get the factor. Next divide 2.9 by that to get your answer. 10/2.25 = 4 4/9. 2.9/ 4 4/9 = 0.6525 --> 0.65
Is that area if so the answer is 12
