If you need more help or info let me know in the comments section!
4x + 2y = 20
3x - y = 10
Multiplying second equation by 2.
6x - 2y = 20
Adding to the first,
10x = 40
x = 4
y = 3x - 10 = 3(4) - 10 = 2
Answer: (4, 2)
Check:
4(4) + 2(2) = 16+4 = 20, good
3(4) - 2 = 12 - 2 = 10, good

Answer:
Step-by-step explanation:
-16x^2 + 32x + 2 = 0
Using the quadratic formula:
x = [-32 +/- sqrt((32^2 - 4*-16*2) / (2*-16)
= 1 +/- sqrt (1152)/(-32)
= -0.06, 2.06.
Answer:
A. 143% B. 70%
Step-by-step explanation:
A. 100/70= 1.4286
