Answer:
17
Step-by-step explanation:
Saying 25+ -8 is basically saying 25-8, and since 25 is the bigger number and it's positive, you get positive 17
You substitute 0 for y and 0 for x to get your points. Also you can make the equation into slope intercept form (y=mx+b) and find the slope and y intercept.

Step-by-step explanation:
pls gimme brainliest if im correct
When x is equal to -1:
f(-1)=6(-1)-3
=-7-3
=-10
y=-10
When x is equal to 0:
f(0)=6(0)-3
=0-3
=-3
y=-3
When x is equal to 1:
f(1)=6(1)-3
=6-3
=3
y=3
When x is equal to 2:
f(2)=6(2)-3
=12-3
=9
y=9
Answer: 21 degrees
Step-by-step explanation:
In the evening, the temperature is 28 degrees and by midnight it has dropped 31 degrees lower, the temperature by midnight will be:
= 28° - 31°
= -3°
Between midnight and 4 am it goes down 6 more degrees. The temperature by 4am will be:
= -3° - 6°
= -9°
Then, by 9 am, the temperature goes up 30 degrees, the temperature at 9 am will then be:
= -9° + 30°
= 21°
