Step-by-step explanation:
Given
for first circle, center is at and radius is units
General equation of circle with center (h,k) and radius r units is given by
for the given circle it is
for second circle center is at (0,-1) and radius is 3 units
Equation is given by
Answer:
1/4 of the work
Step-by-step explanation:
A quarter (1/4) of the work is done in 2 days. Let's break it down:
Work can be finished in 8 days total so with 2 days it is only partially completed. If we set it up as 2/8 we can simplify to get 1/4. Therefore, we know only a quarter of the work is done so far.
Answer:
10, 11, 12, 9.5, 10.5, 11.5, 12.5
Answer:
-2
Step-by-step explanation:
The team skipped 8 times, causing them to lose 8 points. They also guessed correctly 6 times, causing them to gain 6 points. 6 points won - 8 points lost = -2 points total.
Answer:
Step-by-step explanation:
I assume the problem is to graph the lines. The easiest is to pick two values of x and calculate y for each line. For example:
21. y = -4x + 5 I'll randomly choose vales of 1 and 2 for x and calculate y:
(1, 1) and (2, -3)
Now mark those two points and draw a straight line through them. It is an equation of a straight line, so we know this will be correct.
22. Same process:
(1,6) and (2,7)
23. (1,0) and (2,-3)
24. (1,-4) and (2,-6)
=====================
These are shown in the attachment. What's also shown is the second method of producing the lines: Use a graphing program such as DESMOS to plot the equations. The points aren't needed - they are there to demonstrate that the first approach also works.
