A parallel line will have the same slope, which is -4. So the answer so far cannot be A or B.
Put x=-1 in each of C and D and we get y=2 for C and y=1 for D. Since the point is (-1,2) the answer is C.
It’s gotta be C since the “b” term in the equation shows the y intercept; -3 is less than the rest. Don’t listen to the other guy commenting here!
Answer:
$160
Step-by-step explanation:
I = 800 * 5 * 4% (I multiply the time and principal first, so I already have the wholes covered.)
I = 4,000 * 4% (now to convert 4% and 4000 into fractions.)
I = 4000/1 * 1/25 (Cross cancel if needed. GCF is 25.)
I = 160/1 * 1/1 (Just remove 1/1)
I = $160 (There's your answer!)
Multiplying the first equation and multiplying it by -8/3 (to get rid of the x), we get -8y/9+7y= -64+8=-56. Therefore, -56/(-8/9+7)=y and 8- 7(-56/(-8/9+7))=x by plugging it into the second equation
