For the graph of y-5=5x only (-2,-5) is a point, (2,12) is not a point but when 2 is x it is (2,15)
Answer:
9 weeks and the constant is 5 pounds
Step-by-step explanation:
Bob starts at 220 pounds, but his goal is 175. We subtract those two terms to find the number of pounds he is trying to loose. 220-175 = 45. Since we know that he is loosing 5 pounds a week, then we know to divide. 45/5= 9 weeks. The constant would be five because that factor doesn't change. He looses at a constant of 5 pounds.
Answer:
C
Step-by-step explanation:
The rate of change is measured using
in the closed interval [a, b ]
Here [a, b ] = [35, 45 ]
from the table f(b) = f(45) = 34.1 and f(a) = f(35) = 31.4, hence
rate of change = = = 0.27 → C
Answer:
x =28
Step-by-step explanation:
We can use proportions to solve this problem, Put the side of the small triangle over the side of the large triangle.
x 42
------- = -----------
x+10 42 + 15
Simplify
x 42
------- = -----------
x+10 57
Using cross products
57*x = 42 (x+10)
Distrbute 42
57x = 42x+420
Subtract 42x from each side
57x -42x = 42x-42x+420
15x = 420
Divide by 15
15x/15 = 420/15
x =28
