Answer:
y=-3x+10
Step-by-step explanation:
Use point-slope form first.
y-y1=m(x-x1)
Plug the numbers into that.
y+2=-3(x-4)
Distribute and simplify to convert it to y=mx+b
y+2=-3x+12
y=-3x+10
U simply add all the six numbers and divide by it . when you add all the test scores you get 407.6 . Next you divide that by 6 since there were 6 tests taken and the test avg is 81.46 which falls under b category for grades provided from
the table
Answer:
its the only answer
Step-by-step explanation:
0.33
4a^2+7ab-b^2
Step-by-step explanation:
Add the first two equations together:
3a^2-ab-2b^2
+ 2a^2+5ab-3b^2
---------------------------
5a^2+4ab-5b^2
Subtract that answer from the remaining trinomial:
5a^2+4ab-5b^2
- a^2-3ab-4b^2
--------------------------
4a^2+7ab-b^2
J=6
Simply get j by itself by adding 3 to both sides.
