arrange the systems of equations that have a single solution in increasing order of the x-values in their solutions.
2x + y = 10
x − 3y = -2
x + 2y = 5
2x + y = 4
5x + y = 33
x = 18 − 4y
y = 13 − 2x
8x + 4y = 52
x + 3y = 5
6x − y = 11
2x + y = 10
-6x − 3y = -2
y = 10 + x
2x + 3y = 45

f(x)=2/3x-8, which give g(x) the greatest value.

step-by-step explanation:

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
