So...the diameter is increasing at a rate if 2cm/minute, therefore the radius (1/2 the diameter) is increasing at half the rate. You will learn how to calculate the rate of change at a specific point in time in calculus.
Answer:
y = 
Step-by-step explanation:
☆Remember: 
☆Remember: Slope-intercept form -> y = mx + b
☆Now. We first need to find the slope.

☆Now the y-intercept.

She must have multiplied it by 5.
That would've given her:
x - y = 15
2.5x + y = 25
Now we can add them and the y-terms will eliminate each other. Because one is -y, and the other is positive y. -y + y = 0.
Answer:
(3,2)
Step-by-step explanation:
The coordinates of the point P on the given graph is (-1,5).
So, when we translate point P on the graph by 4 units to the right its x-coordinate will change to (- 1 + 4) = 3.
Again, when we translate point P on the graph by 3 units down then its y-coordinate will change to (5 - 3) = 2.
Therefore, the new coordinates of the point P will be (3,2) (Answer)
Your answer is 158 hope this helps.
