Answer:
Step-by-step explanation:
<h3>Given</h3>
- f(x) = 3x-2 and g(x) = 2x+1
<h3>To find </h3>
<h3>Solution</h3>
- (f+g)(x) =
- f(x) + g(x) =
- 3x - 2 + 2x + 1 =
- 5x - 1
Answer:
do 8 times 4.2 then subtract the .6 to get to 33 hope this helped
X = # adults
y = # children
system
24x+16y=$10272
x + y =532
Hello from MrBillDoesMath!
Answer:
The first choice ( -12, 20)
Discussion:
Using matrix multiplication we find the equations:
1x + 1y = 8 (A)
2x + 3y = 36 (B)
Next, compute
2(A) - B =>
(2x + 2y) - (2x + 3y) = 2*8 - 36 =>
(2x - 2x) + ( 2y-3y) = 16 - 36 =>
-y = -20 =>
y = 20
Substituting this y value in (A) gives
x + 20 = 8 =>
x = 8 - 20 =>
x = -12
The answer is the first choice ( -12, 20)
Thank you,
MrB
