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.
Answer:
12y=m
Explaination:
because there's 12 months in a year
I hope this is right
Answer:
30
Step-by-step explanation:
x = 7
( x - 4 )^2 + 3x
= ( 7 - 4 )^2 + 3 ( 7 )
= 3^2 + 21
= 9 + 21
= 30
It’s gonna be all real numbers (-infinity, infinity) because it goes through all the points. And because there’s no restrictions
Answer:
(8,16) (0,22) (10,10)
Step-by-step explanation:
Let x represents the number of hours spent volunteering in school and y represents the number of hours spent volunteering outside of school.
Since each member must spend a minimum of 20 hours doing volunteer work each semester.
The equation forms : 
....(1)
Also given is that the number of hours spent volunteering at school activities can be no more than twice the number of hours spent volunteering outside of school, then equation becomes:
.....(2)
So, lets check with each given pair, if they fulfill both equations:
(7,11): 
is not ≥ 20 - This is false.
(15,6): 
= 12 - This is false.
(8,16): 
which is ≥20 and 
- This is true.
(12,5): 12 is not ≤ 
- This is false.
(0,22): 
and 
- This is true.
(10,10): 
and 
- This is true.
