Answer:ok....
Step-by-step explanation:
Answer:
(0, <u>3</u>), (2, <u>-1</u>), (-6, <u>15</u>)
Step-by-step explanation:
I recommend you use desmos scientific calculator for these problems.
So first you'll wan't to plug in the expression:
y=-2x+3
Then you''l want to put x= then the domains.
x=0, 2 or -6. (it doesn't matter as long as you put them in one at a time.)
youll then get each answer as you plug the numbers in.
x=0 y=3
x=2 y=-1
x=-6 y=15
Sorry if it wasn't clear to understand I'm doing my work at the same time as helping others.
A + b = 21 1/6 --> b = 21 1/6 - a
a - b = 4 3/6
a - (21 1/6 -a) = 4 3/6
a - 21 1/6 + a = 4 3/6
2a = 21 1/6 + 4 3/6
2a = 25 4/6
2a = 154/6
a = (154/6) / 2
a = (154/6) * (1/2)
a = 154/12
a = 12 10/12
a = 12 5/6
b = 21 1/6 -a
b = 21 1/6 - 12 5/6
b = 20 7/6 - 12 5/6
b = 8 2/6
Answer:
a = 12 5/6
b = 8 2/6
Double check:
a + b = 12 5/6 + 8 2/6
a + b = 20 7/6 ......(7/6 = 6/6 + 1/6)
a + b = 21 1/6
a - b = 12 5/6 - 8 2/6
a - b = 4 3/6
