Answer:
x=2
y=1/2
Step-by-step explanation:
x + 2y = 3 Equation 1
3x - 2y = 5 Equation 2
From equation 1, we make x the subject
x + 2y = 3
x=3-2y Equation 3
We substitute x for 3-2y in equation 2 to get y
3x - 2y = 5
3(3-2y)-2y=5
9-6y-2y=5
9-8y=5
9-5=8y
4=8y
Divide both sides by 8
4/8=8y/8
4/8=y
y=1/2
Substitute y for 1/2 in equation 3
x=3-2y
x=3-2(1/2)
x=3-1
x=2
Let's use equation 2 to check if we are correct, note that both sides of the equation must be the same. We substitute x with 2 and y with 1/2
3x - 2y = 5
3(2)-2(1/2)=5
6-1=5
5=5

Answer:
The answer is $206,451
Step-by-step explanation
This scenario is asking to subtract 19 percent away from 229,390 .
Step one : Divide 229,390 by 10 ( take away the zero behind the 9 )
Step 2 : Subtract 22,939 from 229,390 since we know ten percent of 229,390 is 22,939 = 206451

given: f(x) = |x-5|
the function f as a piecewise function
Answer:
20.
Step-by-step explanation:
When x = 2
f(x= 3(2)^3 + 2^2 - 8
= 24 + 4 - 8
= 20.

Answer:
because a positive is over zero and a negative is below zero so from that you can tell that the opposite of any positive will be a negative.
