Answer:
A = - 3 , B = - 3
Step-by-step explanation:
given f(x) divided by (x - h) then the remainder is f(h)
Here f(x) is divided by (x + 1) and (x - 2) , then equate f(- 1) and f(2) to respective remainders and solve for A and B
f(- 1) = A(- 1 - 1) + B(- 1 + 2) = 3 , that is
- 2A + B = 3 → (1)
f(2) = A(2 - 1) + B(2 + 2) = - 15 , that is
A + 4B = - 15 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate A
2A + 8B = - 30 → (3)
Add (1) and (3) term by term to eliminate A
0 + 9B = - 27
9B = - 27 ( divide both sides by 9 )
B = - 3
Substitute B = - 3 into (2) and solve for A
A + 4(- 3) = - 15
A - 12 = - 15 ( add 12 to both sides )
A = - 3
Then A = - 3 , B = - 3
Answer:
y=1/2x+2
Step-by-step explanation:
Please list as brainlist so that I can level up!
Step-by-step explanation:
If we're talking about something like y coordinate being on the x axis, I'd have to say 0. Because it would be on the y axis no matter the coordinates of it isn't a 0. Ex : (0,0) and (0,9). (0,9) would have the point going upwards on the y axis.

Step-by-step explanation:
Let us assume number of points scored by Team B = b points.
Number of points scored by Team A 5 fewer than twice as many points as Team B, that is "5 less than 2b" = (2b-5) points .
Team C scored 80 more points than Team B, that is " 80 more than b" = (b+80) points.
Total number of points scored by all teams = 983 points.
Therefore, we can setup an equation:
<h3>(2b-5) + b + (b+80) = 983.</h3>
Therefore, an equation to represent this scenario using the variable b to represent Team B’s total points is (2b-5) + b + (b+80) = 983.
