Equation 1) 4x + 2y = 8
Equation 2) 16x - y = 14
Multiply all of equation 2 by 2.
2) 2(16x - y = 14)
2) 32x - 2y = 28
1) 4x + 2y = 8
Add equations together.
36x = 36
Divide both sides by 36.
x = 1
Plug in 1 for x in the first equation.
4x + 2y = 8
4(1) + 2y = 8
4 + 2y = 8
Subtract 4 from both sides.
2y = 8 - 4
2y = 4
Divide both sides by 2.
y = 4/2
y = 2
So, x = 1, y = 2

- <u>How to calculate percentage of a number. Use the percentage formula: P% * X = Y</u>
- <u>Convert the problem to an equation using the percentage formula: P% * X = Y.</u>
- <u>P is 10%, X is 150, so the equation is 10% * 150 = Y.</u>
- <u>Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.</u>
- <u>Multiply by 100 and add a percentage </u><u>sign</u>
- <u>0.876 = 0.876 * 100 = 87.6%</u>

I think the answer is B but I am not sure
We have to find the output values for the given input values of the function given as,
Here, x = Input value of the function
And f(x) = Output values
By substituting the input values of x as,
For x = -4,
f(-4) = -4(-4) - 5
= 16 - 5
= 11
For x = 1,
f(1) = -4(1) - 5
= -4 - 5
= -9
For x = 3,
f(4) = -4(3) - 5
= -17
For x = 11,
f(11) = -4(11) - 5
= -44 - 5
= -49
Therefore, Option (A) will represent the output values for the given input values.
