Answer:
(-2, 4) (3, 6)
Step-by-step explanation:
I think this would be correct? haha
y2-y1/x2-x1
6-4=2,3--2(or 3+2 because 2 negatives make a positive)=5, so 2/5.
I hope this helps :)
First, convert "of" to x and put this info into an equation:
Let n represent the unknown number.
14.4 % x n= 10.4
n = 10.4 / 14.4%
n = 72.22222
n = ~72
Hope this helps!
I am going to do number 2 so when you subtract decimals you have to add two zeros like this 10.00 or 0.25 so now when you subtract you get $9.75
You plug in x = 1 and y = -4 into the system of equations and see if they fit:-
y = -4x
- 4 = -4 * 1 = -4 This fits
y = 2x - 2
-4 = 2*1 - 2 = 0 Does NOT fit.
So (1, -4) is not a solution.
