Answer:
C. No solution
Step-by-step explanation:
Eliminate the y terms by multiplying by 28 and 4
28(-9x-4y=1)
4(63x+28y=-6)
This forms
-252x-112y=28
252x+112y=-24----------------------add the y terms to eliminate them
-252x+252x=28+-24
0=4--------------------------x terms also eliminated
No solution
Answer:
Hi there!
Your answer is:
88,000
Step-by-step explanation:
88457
The bolded is the thousands place
8<u>8</u>457
457 is <u>less</u><u> </u><u>than</u> 500, so it's rounded down
88,000
Hope this helps
Okay, so you what you would is solve one equation for Y=mx+b and then substitute this equation for Y so the answer would be Y=-3/2x + 20
And then you would do 2x-3(-3/2x+20)=-11 and you solve it for x
But to get y you would substitute what you got for x into ether equations.
Answer:
Step-by-step explanation:
9(x + 1) = 25 + x
9x + 9 = 25 + x
Bringing like terms on one side
9x - x = 25 - 9
8x = 16
x = 16/8 = 2
