Answer:
A)
Step-by-step explanation:
youjust have to do this:
100 miles-------------------2/3 hour
x-------------------------------3/3 hour or 1 hour
x=100x1/0.6666666667 2/3=0.6666666667
x= 150 miles
For starters, create an equation to show David's earnings. We can do this using Danielle's as a basis, which is set up as y=(# of hours)x+(bonus). This gives us y=12x+80. Now, as we need both their ys to be equal, we just set both equations equal to each other, making 15x+50=12x+80. Now, we solve for x, starting with 15x+50=12x+80, subtracting 12x from both sides to get 3x+50=80, subtracting 50 from both sides to get 3x=30, and dividing three from both sides to get x=10. To check, we just plug in our answer to both equations and see if the ys match up. With Danielle's equation, we get y=15(10)+50=150+50=200 and with David's equation, we get y=12(10)+80=120+80=200, proving that our answer is correct.
Answer:
D
Step-by-step explanation:
Simply put, domain means the x value and range means the y value.
<em><u>The question asks for the corresponding range (y-value) for domain (x-value) of 2. </u></em>
Looking at the graph, x value of 2 corresponds to y value of 4. So the answer is 4.
Correct answer is D
Answer:
A. y = 3x/4
Step-by-step explanation:
a proportional relationship between x and y is a straight line passing through the origin (0, 0).
The equation must be in the form y = kx.
y = 3x/4
y = 3/4x
It is increase, because 15 is less than 18. Other way around, if the question is 18 to 15 yards, then that would be decrease, because it is getting smaller.
