Answer:
2
Step-by-step explanation:
We take the equation
and substitute the values for each individual variable in the problem. It looks like this:
Now we can solve the equation.
When solved, it equals 2.
Answer:
its B
Step-by-step explanation:
Answer:
The correct answer is x = 3 and y = 2.
Step-by-step explanation:
There are many ways to solve systems of equations like this, but I'm going to use substitution. This means taking the value of y given by the second equation and plugging it into the first equation. This is modeled below:
2x - y = 4
2x - (-2x+8) = 4
Now, we can simplify the left side of the equation.
2x + 2x - 8 = 4
4x - 8 = 4
We should add 8 to both sides as the next step.
4x = 12
Now we can divide by 4.
x = 3
To solve for y, we can substitute this value found for x back into either one of our original equations.
y = -2x + 8
y = (-2*3) + 8
y = -6 + 8
y = 2
Therefore, the correct answer is x = 3 and y = 2.

Answer:
562.5ml
Step-by-step explanation:
using percentage multipliers you just have to do:
add 0.25 to 1 because that will make 125%
then multiply it by 450ml
450ml x 1.25 = 562.5ml
Answer:
Slope is 2/-1 the equation would be y=2/-1x+4
Step-by-step explanation:
Use the formula of y2-y1/x2-x1 to find the slope
Plot the two points on a graph and find the y int. (:
