Step-by-step explanation:
<u>Given function:</u>
<u>Convert the equation into vertex form:</u>
- y = 5x² - 20x + 20 + 4 =
- 5(x² - 4x + 4) + 4 =
- 5(x - 2)² + 4
Vertex is (2, 4) at which the minimum y-value is 4
Correct choice is C
Answer:
270
Step-by-step explanation:
Note that 1/10 is equal to 0.1
Multiply 2700 with 0.1
2700 x 0.1 = 270
270 is your answer.

Answer:
20-15z
Step-by-step explanation:
-1+21-15z
20-15z
First calculate the function of x-2y=6:
x-2y=6 | - x
-2y=6-x | ÷ (-2)
y=0.5x-3
Now you have the function. Because the slope you search is parallel to this one, the slope is the same (in this case 0.5). A slope of 0.5 means for 2 steps to the right go one up. To define the function you are searching you have to find out the y intercept. For this take your point (-2|4). Now go as many steps to the right until you reach the y intercept or x=0 in this case you need 2 steps. So for 2 steps right you go one up. Now you have the y intercept (5).
The resulting function is: f(x) = 0.5+6.
