Answer:
A= 80
B= 37
C= 13
D= ? not sure apologies, did this a long time ago.
Step-by-step explanation:
Answer:
x-intercept = .5 y-intercept = 1
Step-by-step explanation:
the x-axis is crossed at .5 and the y-axis is crossed at 1.
Let's call our unknown angle x .
We know that the sum of the three interior angles of a triangle is 180°
This way,
We get that the third angle measures 29°
Answer:
1 hour and 7 minutes
Step-by-step explanation:
- set up two equations: =
- cross multiply: 4.42x =294
- solve for x: 294 ÷ 4.42 = 66.52 or 67 minutes
The question is asking for hours rather than minutes so...
- 1 hour is 60 minutes
67 min - 60 min = 7 min
Therefore, it would take 1 hour and 7 minutes to fill a 294-gallon hot tub.
Where f(x)=0 is the zeros of the funciton
factor out the common factor of all of them which is 9x
f(x)=9x(x^2+2x-15)
what 2 numbers multiply to get -15 and add to get 2?
5 adn -3
f(x)=(9x)(x+5)(x-3)
set to zero
9x=0
x=0
x+5=0
x=-5
x-3=0
x=3
zeroes at x=-5, 0,3
