Hello :
<span>3x-y=4 .....(1)
-9x+3y=-12 ....(2)
by (1) : y = 3x-4
in (1) : -9x +3(3x-4) = -12
-12=-12
infinity solution : ( x , 3x-4) x in R</span>
Which expression is it that you're talking about?
Answer:
a) 90(1 + 0.01r)⁶
b) $113.22
Step-by-step explanation:
90 (1 + r/100)⁶
90(1 + 0.01r)⁶
r = 3.9
90(1 + 3.9/100)⁶
113.2232964
Answer:
Yes
Step-by-step explanation:
it is the same answer for both if you solve it. it is y=2/3,−4. the , is to mean or.
If two angles are complementary, it means their angle measures add to 90
Hope this helps
