Answer:A quick way to solve this problem involves copying the given equation:
2x + 5y = 10
dropping the final 10, and
substituting the given x and y values: (5, -4).
Then:
2(5) + 5(-4) = C C = 10-20 = -10
Thus, the equation of this new, parallel line is 2x + 5y = -10.
Step-by-step explanation:

the fastest way to do it
Answer:
Step-by-step explanation:
{y = 5x - 2
{x + 4y = 8
Use the Substitution Method:
x + 4[5x - 2] = 8
x + 20x - 8 = 8
21x - 8 = 8
+ 8 + 8
__________
21x = 16

21 21
x = 16⁄21 [Plug this back into both equations above to get the y-coordinate of 1 17⁄21]; 1 17⁄21 = y

Answer:
C.f(2) = 12.6
Step-by-step explanation:
f(n) = 0.4 ⋅ f(n − 1) + 11
f(1) = 4
Let n=2
f(2) = .4 f(1) +11
= .4 (4) +11
= 1.6 +11
= 12.6
Answer:
10 calories per minute
Step-by-step explanation:
We do not have much information to go on such as the speed that Tai is biking or his/her weight. Regardless we can use the data gathered by the University of Harvard which after a study came up with the following results. Their results showed that if an individual bikes at a speed of 13 mph and are around 155 pounds they will burn calories at a rate of 10 calories per minute. Therefore we can assume that Tai is burning roughly 10 calories per minute. This rate increases if the person bikes at a faster speed or weighs more as they are exerting more energy.
Answer:The answer will be 20
Step-by-step explanation: If you are given the circumference of something all you have to do is divide it my pi (3.14) to get the answer. If you know the diameter and is looking for the circumference you multiply the diameter by pi. Hope this helps.
