Here is a graph of the radius and circumference of
several objects.
What is the constant of proportionality in this
relationship?
Answers
Answer:
6.285
Step-by-step explanation:
Let’s say we have X which we know is 5, and we have the constant of proportionality of 2. We can then find Y by rearranging the equation Y = X*C = 5*2 = 10.

Solve for x.
3x/-8 =−21/4
Enter your answer in the box.
Answers
Answer:
x = 14
Step-by-step explanation:
3x/-8 = -21/4
(3x/-8)×-8 =( -21/4)×-8
3x = 42
3x/3 = 42/3
x = 14
hope it's helpful
Answer:
x = 14
Step-by-step explanation:
to solve this you have to first move 3/-8 to the other side and divide while keeping x on the same side.
now to divide you must flip over 3/8 and multiply so 21/4 x 8/3 ( negative sign cross off because there are two of them) so 3 and 21 cross off leaving 7 in the numerator 4 and 8 cross of leaving 2 in the numerator and then 7 and 2 get multiplied and you will get 14.
i dont know how to do graphing pls help
Answers
Answer:
Solution: (-1, -1)
Step-by-step explanation:
y=4x+2
y=-4/3x-2
Solve by graphing.
First, you need to plot the y-intercept.
y=4x+2
2 will be your y-intercept.
Next, you plot your slope.
y=4x+2
From your y-intercept, you will go up 4 and right one space, if you run out of space go down 4 and left 1.
Now repeat the same steps for the next one.
y=-4/3x-2
Plot your y-intercept.
y=-4/3x-2
because your slope is negative you will go down 4 and right 3, if you run out of room go up 4 and left 3.
Then draw connecting lines and wherever the lines intersect, that's going to be your solution. In this case, the solution is (-1, -1).

This graph shows how many miles are in a league. What is the constant proportionality for this graph?
Answers
running out of constant rate Gina ran 15 miles in a time of 150 minutes how many minutes does it take to run in 6 minutes?
Answers
Step:
15/150 = 6/x
Cross multiply
15x=900
Divide by 15
X=60
Answer:
.6 or 6/10 of a mile
Step-by-step explanation:
Divide 150 by 15 which equals 10 which means that Gina was moving at 1 mile in 10 minutes. So now we know that Gina was moving at .1 or 1/10 mile a minute so 6 minutes is 6/10 or .6 of a mile.

Answer:
b² + c² = 47
Step-by-step explanation:
Expand (b + c)² = 61
⇒ (b + c)(b + c) = 61
⇒ b² + 2bc + c² = 61
Substitute bc = 7 into b² + 2bc + c² = 61:
b² + 2(7) + c² = 61
b² + 14 + c² = 61
To determine b² + c² simply subtract 14 from both sides of the equation:
b² + c² = 47
