Answer:
undefined
0
Step-by-step explanation:
We can use the slope formula
m = (y2-y1)/(x2-x1)
m = (-7 -5)/(-6 - -6)
= (-7-5)/(-6+6)
-12 /0
undefined
m = (y2-y1)/(x2-x1)
m = (-3 - -3)/(7 - -8)
= (-3+3)/(7+8)
= 0/15
= 0
Answer:
x+2y=12
Step-by-step explanation:
I used DESMOS graphing calculator. I highly recommend it for problems like this.
It’s A- 18+14. You do 2 x 9= 18 and 2x7= 14
The question does not seem complete, but I'll represent the statement mathematically and look for their ages each. This is because the worst they can ask for is their ages.
Let C stand for Courtney's age, A for Andrei's age, N for Natalie's age and S for Shari's age. From the question we can deduce the following:
C = 2A
C = N + 3
C = S/2
S - N = C + A
S = 2C, N = C - 3 and A = C/2, therefore we have
2C - (C - 3) = C + C/2
C + 3 = C + C/2
C/2 = 3 and C = 6
A = C/2
A= 6/2
A = 3
N = C - 3
N = 6 - 3
N = 3
S = 2C
S = 2 x 6
S = 12.
C = 6, A = 3, N = 3 and S = 12
