Y = (-4/3)x that is the right answer
Answer:
(5, -9)
Step-by-step explanation:
f(x)=(x-8)(x-2)
We want the vertex. So let us get this in Vertex Form.
f(x) = (x - 8)(x - 2) = x^2 + 16 - 10x
f(x) = x^2 - 10x + 16
f(x) = x^2 -10x + 25 - 25 + 16
f(x) = (x^2 -10x + 25) - 25 + 16
f(x) = (x - 5)^2 - 9
Vertex at (5, -9)
Answer:
a=2(s-5)
a(your age): 20
Step-by-step explanation:
a stands for your age
s stands for sister
a=2(s-5)
1-substitute 15 for s a=2(15-5)
2- a=2(10)
the 15-5 stands for sisters age minus five which gives you brothers age, 10. You multiply it by two because your brother is half your age.
3-a=20
check your work:
because your brother is 10 and you are 20, he is half your age (10/20 can be simplified to 1/2)
Hope this helped, if you have any other questions please lmk!
The answer for this is -1x.
Proabably. 5 because if there is 2 sides on a coin then you should divide 10÷2 which is 5.
