I REALLY need help with this worksheet. it is due tonight and I really don't understand it
Answer:
Step-by-step explanation:
Basically, try finding the x and y intercept for each problem and then make those your coordinates!!
Step-by-step explanation:
1) So to answer these questions first plot the "b" value (which in number 1's case would be 3).
2) Go up three spaces on the graph. and that should leave you at the point (0,3) Plot this point.
3) Now go down 3 (-3x) and go over one point to the right(this should put you at point (1,1). Plot this point.
4) Move on to the next equation in number one. Go up three spaces on the graph.
5) Go down one and over one until you find that you have plotted a point in which both equations intercept (this point would be (0,3).
6)Repeat this process for the rest of the problems
Dont guess!
I will mark brainliest if its correct!

I really don't get what I'm supposed to do...
Answer:
check below
Step-by-step explanation:
1. c = 68-27 = 41
2. t = 7.9+1.5 =9.4
3. a = 21*3 = 63
4. (multiply whole equation by 8) 8r+6=7, r=1/8
5. x = 25.2/4.2 = 6
6. b = 75/15 = 5
7. A. 6C = 99
B. C = 99/6 = $16.50

Identify the x- and y-intercept and graph the equation on the coordinate plane to the left. What is the y-value when x is 2? Answer these questions in the text box below.
Answer:
x int is (6,0). y int is (0,4) and y value when x is 2 is 8/3
Step-by-step explanation:
to solve these questions, we can simply plug everything in. The x intercept for Example, is where the y is equal to 0. So we can plug in 0 for y to get the x int, and vice versa for the y int. To find out the y value when x is two, plug in x as two
2 times 2 +3y=12
3y=8
y=8/3

Carli’s class built some solar-powered robots. They raced the robots in the parking lot of the school. The graphs below are all line segments that show the distance d, in meters, that each of three robots traveled after t seconds.
1) Each graph has a point labeled. What does the point tell you about how far that robot has traveled?
Robot A:d =
Robot B:d =
Robot C:d =
2) Carli said that the ratio between the number of seconds each robot travels and the number of meters it has traveled is constant. Is she correct? Explain in detail.
3) How fast is each robot traveling? How did you compute this from the graph?
Robot A:
Robot B:
Robot C:

someone help me with my math...no bias answers, please
Answer:
61.8m^2are
Step-by-step explanation:
3 times 9 = 27
you multiply that two more times because there are 3 of them. So now we have 54 m.
Now we find the area of the triangles
area = 1/2 base times height
1/2(2.6) * 3
1 * 2.6 * 3/2
2.6 * 3/2
7.8/2
3.9
3.9 times 2 because there two triangles
7.8 + 54 = 61.8 m^2

She can expect to hit the bullseye 5 times.
Answer:
A. 5
Step-by-step explanation:
Regina throws 25 darts and hits the bullseye 20% of the time. So we would set up the equation as 0.20*25 (as we are looking for 20% of 25 and of means multiplication and 20% is 0.20). 0.20*5=5 so she can expect to hit the bullseye 5 times. Therefore, A is the correct answer choice.
