D) x=-3, y=-7
Step-by-step explanation:
9x - 7y = 22
x + 3y= -24
x= -24-3y
9(-24-3y)-7y=22
-216-27y-7y=22
-34y=22+216
-34y=238
y=238/(-34)
x=-24-3y
y=-7
x=-24-3*(-7)
x=-24+21
x=-3
(x,y)=(-3,-7)
i think it's either c or d
step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.
