Answer:
D. 
and 
Step-by-step explanation:
The vertex of a function is controlled by the translations of the x and y value. Moving a vertex up and down is connected to the vertical position or the y-value. The y-value is the value that is added to the variable and is not squared.
Vertex form of a function is 
. In this case, k controls the vertical position of the vertex. If k is negative then the vertex will be moved down. So, if you want to move a vertex down by 5 units, then the k value must be -5.
Plug this into the formula to get the equation for k(x). This means that k(x) must equal 
.
Answer:
To make that easier to follow you are asking "what is
-(8/5) divided by -(2/3)? That equals
-(8/5) multiplied by -(3/2) which equals
24 / 10 = 12 / 5 = 2.4
Step-by-step explanation:
Answer:
21:24
Step-by-step explanation:
7:8 is your ratio
so if _:24 is equivalent, you have to figure out what 24 is divisible by to equal 8
8×3=24
so now we have to multiply 7 by 3
7×3=21
so your answer is 21:24 = 7:8
hope this helps :)
Answer:
Step-by-step explanation:
ok so you start off by adding
14.30
143.08
<u>19.74</u>
177.12
177.12 is close to 180 if u estimate in tens, 177 if ones
