Answer:
(8,4)?
Step-by-step explanation:
Answer:
10%
Step-by-step explanation:
First, 97.90-89=8.90
8.90/89 = x/100
8.90 x 100 = 890
890/89=10%
Check Answer:
89 x 10%=8.90
89+8.90= 97.90
Therefore, the sales tax percentage is 10%
Answer:
therefore y= - (x-2)^2 + 5
Step-by-step explanation:
u do this by using this format here ..,
y=a(x-h)^2+k
sub in the vertex points as h=2 and k = 5 , since the 2 is positive its sign will be -2 in the brackets because when solving for x-2=0 it is x=2
y=a(x-2)^2+5
then with your (0,1) points plug that in as y and x
1=a(0-2)^2+5
1=a(-2)^2+5
1=4a+5
1-5=4a
-4=4a
a=-1
therefore y= - (x-2)^2 + 5
Oh these are easy, I’ll explain.
To start off, the answer is 11.
I got this by subtracting DE (57) and BC (35). You get 22. Then, you divide the result of the subtraction by 2, which is 11.
Let me know if you need me to explain in more depth, and give brainliest if I’m correct tysm.
