Step-by-step explanation:
30 / 5 = 6
28 / 4 = 7 the person above me was right
Answer:
You can use Gaussian Elimination.
Double both sides of the first equation and add the second equation.
6x + 4y = 8
5x - 4y = 3
---------------
11x = 11
x = 1
5 - 4y = 3
-4y = -2
y = 1/2
Step-by-step explanation:
Answer:
$.999 for 1 pound
Step-by-step explanation:
If you divided both sides by 10. So 10/10= 1. 9.99/10= 0.999
Answer:
Slope = (-5,0)
Step-by-step explanation:
When given two points and asked to find the slope, you can find the answer using slope formula which is:
slope = (y2 - y1) / (x2-x1)
You have been given the points (3,4) and (3,-1). You can select which ones to be x1 and y1 and which ones to be x2 and y2. It doesn't matter which, so let's just do (3,4) are x1 and y1 and (3,-1) are x2 and y2. Now we can plug it into the formula.
Slope = (-1 - 4) / (3-3)
= -5 / 0
= -5,0
So the answer is (-5,0).
