Answer:
Step-by-step explanation:
this is a radical equation:
when x=1 y=0
reflected about x
-sqrt(x)
right 1 unit
-sqrt(x-1)
it looks like y-int is about (0,1/3)
vertically compressed by a factor of 1/3
-(1/3)sqrt(x-1)
if you think the y-int is more (0,1/4), then
the function is vertically compressed by a factor of 1/4
-0.25sqrt(x-1)
The solution to the equation is x = 20.
<u>Step-by-step explanation</u>:
The equation is 2( x – 5) = 9 – 3 x + 6 + 8 + 3 x + 7
2x - 10 = 30
2x = 30+10
2x = 40
x = 40/2
x = 20
Answer:
250 Students are musicians, 200 are not.
Step-by-step explanation:
Decimal Version:
If we take "5 out of every nine students are musicians" and make this a fraction we get 5/9. 5/9 as a decimal is approximately 55.555555555556. 55.555555555556% of 450 = 250. So that means 250 students are musicians.

Answer:
y = -x - 11
Step-by-step explanation:
We know the equation must be: y = -x + c
However we do not know what "C" is. If we plug in our x and y values then we can find out the value of C.
So:
-1 = -(-10) + c
-1 = 10 + c
so c = -11
So our equation is:
y = -x - 11
6:00-30 minutes is 5:30
5:30-15 minutes is 5:15
5:15-45 minutes is 4:30
She started on 4:30 pm
