It would be answer choice B.
Correct work shown below:
1/2(4K+8) = 10
2k + 4 = 10
2k = 6
k = 3
Answer:
x = 8, y = 3
Step-by-step explanation:
Equating corresponding x and y coordinates , then
- y = - x + 5 ( multiply through by - 1 )
y = x - 5 → (1)
2x - 5y = 1 → (2)
Substitute y = x - 5 into (2)
2x - 5(x - 5) = 1 ← distribute and simplify left side
2x - 5x + 25 = 1
- 3x + 25 = 1 ( subtract 25 from both sides )
- 3x = - 24 ( divide both sides by - 3 )
x = 8
Substitute x = 8 into (1) for corresponding value of y
y = 8 - 5 = 3
The answer to this question is (2, -2) and (0, -2)
Why: imagine a graph with a line through it. When the line hits the y-axis (anywhere) the value for x is always zero. When you look at the answer, I chose, you can tell that in the second coordinate pair the first number is zero which represents x and the second number is -2 which is what you said y equals to.
Hope this helped
Answer:
-\left(\dfrac{1}{2}y+\dfrac{1}{4}\right)=-\dfrac{1}{2}y-\dfrac{1}{4}=-\dfrac{1\cdot2}{2\cdot2}y-\dfrac{1}{4}=\dfrac{-2y}{4}-\dfrac{1}{4}=\dfrac{-2y-1}{4}\\\\=-\dfrac{2y+1}{4}
