Step-by-step explanation:
h*w*l=v
Answer: Second option: (4,0) and (-9,0)
f(x)=x^2+5x-36
The x-intercepts of the graph of a function f(x) are the values of the variable x that makes f(x)=y equal to zero. To find these values we only have to equal f(x)=y to zero:
f(x)=y=0
x^2+5x-36=0
Factoring the polynomial:
(x+9)(x-4)=0
Using that if a b=0, then: a=0 or b=0
with a=x+9 and b=x-4
x+9=0 or x-4=0
Solving for x:
x+9-9=0-9 or x-4+4=0+4
x=-9 or x=4
Then the x-intercepts are the poitns (x,y)=(x,0):
(4,0) and (-9,0)
Hello!
OK, so first we need to see all of our info.
To rent a bike = $17
Each additional hour = $2 per hour
Let "rent a bike" = r
Let "each additional hour" = h
27 = r + 2h
Now to solve.
27 - 17 = 10
10 ÷ 2 = 5
This shows us that she rented the bike for 5 hours.
Check:
27 =? 17 + 2(5)
Solve:
27 = 17 + 10
27 = 27
Yes, we are correct!
Final equation = 27 = r + 2h
Final answer = Ashely rents the bike for 5 hours.
Hope this helped!
