Answer:
Step-by-step explanation:
We can do this a couple of ways. We can graph it -- see below. Or we can do the math.
Math
y = x^2 - 2x - 15
This trinomial factors into
y = (x - 5)(x + 3)
from which
x - 5= 0
x = 5
and
x + 3 = 0
x = - 3
The y intercept is the value obtained when all the xs on the right = 0
y = 0^2 - 2*0 - 15
y = - 15
<em>Answer</em>
- x intercepts: (-3,0),(5,0)
- y intercept: (0,-15)
The graph is below.
Answer:
Step-by-step explanation:
Let the two whole numbers be 5x and 2x then
by the question
5x - 2x = 33
3x = 33
x = 33/3
x = 11
Therefore the numbers are
- 5x = 5*11 = 55
- 2x = 2*11 = 22

121/150 or 0.0806. The 6 is repeating itself.
Answer:
Jalen lost 12 pounds in the first 3 weeks
12/3=4 per week
than the weight loss slowed by half, meaning he lost 6 pounds in 3 weeks
6/3=2 per week
84-12=72 to loose after 3 weeks
72/2=36 weeks
to loose 84 pounds you need 3+36=39 week

Answer: add 1 to both sides
-1+r+1≥4+1
simplify
