Answer:
<h2>M(-a, b)</h2>
Step-by-step explanation:
Use the formula of a midpoint:
We have the points P(-2a, 0) and Q(0, 2b). Substitute:
Answer:
$ 4.75
Step-by-step explanation:
In this case we can solve it using a 2x2 system of equations, like this:
let x: price of drinks
let y: bags of popcorn price
SW:
3 * x + 5 * y = 26.75
9 * x + 2 * y = 18.50 => x = (18.5 - 2 * y) / 9
Replacing, we are left with that:
3 * (18.5 - 2 * y) / 9 + 5 * y = 26.75
6.167- 0.67 * y + 5 * y = 26.75
- 0.67 * y + 5 * y = 26.75 - 6.167
4.33 * y = 20,583
y = 20,583 / 4.33
y = 4.75
Now to calculate x:
x = (18.5 - 2 * 4.75) / 9
x = 1
That is, the value of the drinks is $ 1 and the value of bags of popcorn is $ 4.75
Answer:
Step-by-step explanation:
x+ 8/4 -x+ 5/4
= x+2+-x +5/4
Combine Like Terms:
x+2+-x+ 5/4
(x+x)+ ( 2 +5/4)
= 13/4
Answer:
3/1 or 3
Step-by-step explanation:
It rises up three and to the side one
