Answer:
The value of a is 80
Step-by-step explanation:
The distance of a point
from the y-axis can be written as
because the x-coordinate of the y-axis is zero.
Similarly, the distance of a point from the x-axis can be written as 
since the y-coordinate of the x-axis is zero.
In this problem:
- The distance of the point A (−30, −45) from the y-axis can be written as

- The distance of point B (5a,2a) from the x-axis can be written as

Since 
We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means

Therefore,

And solving for a,

The question is a blank black box...can you resend with actual picture...
Answer:
The graph that represents the function should look like the image I attached. To graph the function simply multiply five by zero to find the value of y. Once you see that the value of y is zero graph the y-intercept at (0, 0). Finally, you draw a horizontal line from the y-intercept.
Answer:
The best is Option D, because the number 7.28 is between 7 and 8 which is a good estimate.
Step-by-step explanation:
Since the square root of 53 is: 7.28...
sqrt(36) = 6
sqrt(64) = 8
sqrt(81) = 9
sqrt(49) = 7
Option D would be the best estimate
Answer: The best is Option D, because the number 7.28 is between 7 and 8 which is a good estimate.
