This is vertical reflection, because reflections are made across vertical lines.
Answer:
x=5.6
y=-5.6
Step-by-step explanation:
3x - 5y = 14 Equation 1
– 2x + 2y = 0 Equation 2
Simultaneous equation can be solved either through elimination method or substitution method. But we use elimination method for this question
Multiply equation 1 by -2 (the coefficient of x in equation 2) and multiply equation 2 with 3 (the coefficient of x in equation 1), so that x will have the same coefficient in the new equations, and easy to eliminate
-2(3x - 5y = 14)
-6x+10y=-28 Equation 3
3(– 2x + 2y = 0)
-6x+6y=0 Equation 4
Subtract equation 4 from 3 to eliminate x
-6x+10y=-28
-6x+6y=0
-6x-(-6x)=-6x+6x=0
10y-6y=5y
-28-0=-28
5y=-28
y=-28/5
y=-5.6
Substitute for y in equation 2
– 2x + 2y = 0
– 2x + 2(-5.6) = 0
-2x-11.2=0
-2x=11.2
x=-11.2/2
x=5.6
I think the answer you are looking for is $2,592
Answer:
n>9
Step-by-step explanation:
4(n-3)- 6 > 18
To solve this inequality we need to remove the parenthesis
distribute 4 inside the parenthesis
4n -12 - 6 > 18
Now combine like terms
4n - 18 > 18
We need to isolate 'n', so we add 18 on both sides
4n > 36
Now divide both sides by 4
n > 9
So the value of n is greater than 9
