Answer:
2.5 or 250.
Step-by-step explanation:
Answer:
To make it trinomial it has to be ax²+bx+c
Using elimination method to find y
3x - 4y = -15 (multiply 4)
4x + 3y = 5 (multiply 3)
------------------------------------
12x - 16y = -60
12x + 9y = 15
--------------------- - (substract)
-25y = -75
y = 3
Using subtitution method to find x
3x - 4y = -15
3x - 4(3) = -15
3x - 12 = -15
3x = -3
x = -1
The solution (-1,3)
Yes it makes since both answers come out to 2.236
Answer:
w = -16
Step-by-step explanation:
w + (-2) = -18
-18 - (-2) = w = -16
w= -16
Check your work:
-16 + (-2) = -18
