G=gas
w=bottle of water
8g + 2w = 29
12g + 4w = 45
I'm going to use elimination to cancel out the variable w by multiplying the first equation by -2.
-16g - 4w = -58
12g + 4w = 45
-4g = -13
/-4 /-4
g = 3.25
Now plug it into an equation, any equation.
8 (3.25) + 2w = 29
26 +2w=29
w=1.5
Now to check, plug it into both equations if you want.
12 (3.25) + 4 (1.5)=45
39 + 6=45
One bottle of water is $1.50, while one gallon of gas is $3.25.
Answer:
-7/5
Step-by-step explanation:
3(x + 1) + 2 (x + 2) >0
(3x + 3) + (2x + 2 * 2) >0
(3x + 3) + (2x + 4) >0
= -7/5
I think the answer is C

Answer:
A, C, F, G, I
Step-by-step explanation:
A relation is "odd" if it is symmetrical about the <em>origin</em>. That is, f(-x) = -f(x). Here are the symmetries of the graphs shown:
A: origin
B: y-axis
C: origin, and x- and y-axes
D: x-axis
E: no symmetry
F: origin
G: origin, and x- and y-axes
H: x-axis
I: origin, and x- and y-axes
