A vertical stretch by a factor of 2 of F(x) = -2|x-2|+4 would result in the revised function G(x) = -4|x-2|+4. The vertex would stay in the same place (2,4).
Answer:
Slope = 
Step-by-step explanation:
(x₁ , y₁) = (-9 , -4) & (x₂ ,y₂) = (-3, -6)
Slope = 
![= \frac{-6-[-4]}{-3-[-9]}\\\\= \frac{-6+4}{-3+9}\\\\= \frac{-2}{6}\\\\= \frac{-1}{3}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B-6-%5B-4%5D%7D%7B-3-%5B-9%5D%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-6%2B4%7D%7B-3%2B9%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-2%7D%7B6%7D%5C%5C%5C%5C%3D%20%5Cfrac%7B-1%7D%7B3%7D)
I’m not sure I understand the question
Answer:
21 liters of the 12% solution and 4 liters of the 37% solution
Step-by-step explanation:
Represent the number of liters of the first solution as x and the second as y. Now, the total liters of iodine is going to be 16% of 25 = 4 liters of iodine, and the total liters of each solution is going to be 25. Now, we can setup two equations:
0.12x+0.37y = 4
x + y = 25
Multiplying the bottom equation by 0.12, we have
0.12x + 0.12y = 3
Subtracting, we have
0.12x+0.37y=4
-
0.12x + 0.12y = 3
= 0.25y = 1
= y = 4
= x = 25 - 4 = 21
Answer:
m=25/12
Step-by-step explanation:
multiply the reciprocal of 2/5 on both sides
