Answer:
A. x=2, y = 7.
B. (2, 7).
Step-by-step explanation:
A. You can eliminate y by subtracting the equations:
y = 8x - 9
y = 4x - 1 Subtract:
0 = 4x - 8
4x = 8
x = 8/4 = 2.
Now substitute for x in the first equation:
y = 8(2) - 9 = 7.
Check in the second equation:
y = 4x - 1
7 = 4(2) - 1 = 7. Check is OK.
B. On the graph they will intersect at the point (2, 7).
They will intersect here because the values x=2 and y=7 satisfy both the 2 equations.
44 fl oz there are 2000 pounds in a tone for x amount of supplement… ( supplement volume)/(weight in pounds) = x/(5.5*2000)=1/250 multiplied by 11000
x=11000/250=44 fl
R - 5 1/6 = 10
r - 31/6 = 10
+ 31/6 +31/6
r = 91/6
So, r = 91/6.
And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.
8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
+7 +7
8x = 21
x = 21/8
So, the answer is 21/8
