The question being the case, the equation is: 8x + 6y = 136.
Where x is the number of hours spent on job A and y is the number of house spent on job B. Now to solve for both variables.
Notice that if you add x and y, you should get a total of 20 hours so x + y = 20.
To get x, x = 20 - y. Replace the answer on the original equation gives you 8(20-y) + 6y = 136.
160 - 8y + 6y = 136
160 - 2y = 136
-2y = 136 - 160
-2y = -24
<span>Solve for y by dividing both sides of this equation by -2 to get y:
y = 12
Replace y on the x + y = 20 equation to get x.
x + 12 = 20
x = 20 = 12
x = 8
Therefore:
x = 8 hours on job A
y = 12 hours on job B
Hope this helps!</span>
ANSWER
C. Yes; the graph passes the vertical line test.
EXPLANATION
The quickest way to determine whether a graph represents a function or not is to perform the vertical line test.
If the graph passes the vertical line test, the graph represents a function.
If we draw vertical line across the graph in the attachment, it will touch the graph at one and only one point.
Since the graph passes the vertical line test, it represents a function.
Answer:
C) 12.75
Step-by-step explanation:
4x=51
x=51/4
x=12.75
Its D. they are equidistant from the center of the circle , just took the test and that was the answer on apex
The answer is 6, K-N is 4, and I-K is 2, and as we all know, 4+2=6
