Answer:
The answer is
Step-by-step explanation:
The above variation is written as
Where k is the constant of variation
y = 16 x = 1/2
So the expression for y in terms of x is
Hope this helps you.
You can eliminate c) because it only had one inequality symbol. Then you subtract 1 from both sides to get x by itself. 6 divided by 3 gives you two. You now have choices A and B. The answer will be B because x represents all values that are less than 2, not just 2 plotted on the number line..
Answer:
Step-by-step explanation:
Just by looking at the graph, we can see that the x value of the center of the circle has to be positive and the y value negative. Only the first and last choices fit this. and (5, -3) is at the center. (3,-1) is nowhere near the center. So your choice is correct
The radius of the circle will be the distance from the center to any point on the circle
We know the center is at (5, -3) and the circle passes through (3,1). So we have to find the distance between these two points. Call it r
By the Pythagorean theorem, distance, r between any two points on a 2-D coordinate is given by
where the coordinates of the two points are (x1, y1) and (x2, y2)
We have x2 = 3, x1=5 and y2 = 1, y1 = -3
r = = = =
Answer:
ABC
Step-by-step explanation:
Answer:
3 hours
Step-by-step explanation:
Let the number for hours afterward be represented as: x
The veteran tutor charges $15 for the first session plus $60 per hour afterward.
This is expressed as
$15 + $60 × x
15 + 60x
The new college graduate charges $45 for the first session plus $50 per hour afterward.
$45 + $50 × x
45 + 50x
The number of hours these two must tutor in order to earn the same amount of money is calculated as:
Veteran tutor = New college graduate tutor
15 + 60x = 45 + 50x
60x - 50x = 45 - 15
10x = 30
x = 30/10
x = 3 hours
Therefore, the number of hours these two must tutor in order to earn the same amount of money is 3 hours
