Step-by-step explanation:
graph, find length between points (sqrt 20) and slope (-2). sqrt20/2=sqrt5.
change in y/change in x = -2, change in y squared + change in x squared= 5. solve system of equations to get x=1, y=-2, or x=-1, y=2. i think i did something wrong but the answer should be correct

Step-by-step explanation:
Write the percent as a fraction or mixed number in simplest form.
148%
Answer:
1 and 12/25
its over 100 percent, that's where the 1 comes from. the 48 that's left would be 48/100, which is then simplified to 24/50, which is simplified one more time to 1 12/25
Answer:
Fraction: 37/25
Step-by-step explanation:
148/100
(reduce by dividing both by 2) 74/50
(reduce by dividing by 2 again) 37/25

Lisa and Marie are both on the track team. During practice, Lisa ran 10 laps around
the track in 18 minutes. Marie ran 8 laps around the track in 14 minutes. Who ran at a
faster rate? If each runner continues at her same pace, how long would it take each
one to run 15 laps?
Answer:
Marie ran at a faster rate. It takes 27 minutes for Lisa to run 15 laps while it takes Marie 26.25 minutes to run 15 laps.
Step-by-step explanation:
18 ÷ 10 = 1.8 (Lisa's rate)
14 ÷ 8 = 1.75 (Marie's rate)
1.8 x 15 = 27 minutes (How long it takes for Lisa to run 15 laps)
1.75 x 15 = 26.25 (How long it takes for Marie to run 15 laps)

What is the solution to this system of equations?
X+ 2y = 4
2x-2y = 5
O (3.-53
0
(3.)
no solution
infinitely many solutions
Answer:
X+2y=4
4+2y=x
2(2+y)=x
2x-2y=5
2(x-y)=5
x-y=5/2
Answer:
(x, y) = (3, 1/2)
Step-by-step explanation:
x + 2y = 4
2x - 2y = 5
There is more than one way to do this. I will do it by substitution.
From the first equation, x + 2y = 4, so x = (-2y) + 4
Now, in the second equation, I will replace x with (-2y + 4)
2(-2y + 4) - 2y = 5
-4y + 8 -2y = 5
-6y + 8 = 5
-6y = -3
6y = 3
y = 3/6
---------------------------------> y = 1/2, one part of the answer
Now I can go back to the first equation, and relpace 'y' with 1/2
x + 2(1/2) = 4
x + 1 = 4
-----------------------------------> x = 3, the other part of the answer
So now we believe the solution is (x, y) = (3, 1/2)
Now check the answer, back in the original equations!!
------> In the first equation, we would have 3 + 2(1/2) = 4.
3 + 1 = 4
That is true
-------> In the second equation, we would have 2(3) - 2(1/2) = 5
6 - 1 = 5
That is true
Our answer is found and checked.
(x, y) = (3, 1/2)
its scale factoring, please help thanks

A certain animal gets food from another animal without killing it. Identify the type of organism.
(A) Saprophyte
(B) Carnivore
(C) Parasite
(D) Autotroph
Answer:
The correct answer is C. Parasite.
Step-by-step explanation:
Parasitism describes the phenomenon within the animal and plant world that an organism or virus (parasite) misuses a usually considerably larger organism of a different species as a host. The host serves the parasite for food supply (mostly in the form of blood or other body secretions) and in some cases also as a long-term habitat. The host's health is damaged by the parasite, but usually remains alive. The consequences of parasitic infestation range from sting or bite injuries from massive physical complaints to serious infectious diseases and even death in extreme cases. The best known and most widespread human parasites are human lice, mosquitoes and various types of ticks and worms.
