First solve the second equation to equal x.
x + y = 550
Subtract y from both sides.
x = 550 - y
Put this into the first equation in place of x.
3.75 (550 - y) + 4y = 2160
Multiply everything in the parenthesis by 3.75
2062.5 - 3.75y + 4y = 2160
Combine like terms.
2062.5 + 0.25y = 2160
Subtract 2062.5 from both sides.
0.25y = 97.5
Divide 0.25 on both sides.
y = 390
Put this into the second equation in place of y.
x + 390 = 550
Subtract 390 from both sides.
x = 160
So x = 160 and y = 390
Hope this helps!
Answer:
(f*g)(x) = 3x^3 + 6x^2
Step-by-step explanation:
Since we are looking for the result of multiplying the equations (f*g), we must multiply the right sides together
(f*g)(x) = (3x^2)(x+2)
To get from here to the solutions, we must multiply the first term by all parts in the second term
3x^2 * x = 3x^3
3x^2 * 2 = 6x^2
from there, just put them back in the equation
(f*g)(x) = 3x^3 + 6x^2
