Answer:
C
Step-by-step explanation:
Factor: -7x^2 -5x+18
Factor -1 out of 7x^2 -5x +18:
−(7x^2+5x−18)
Factor.
1. 18 is negative, so a negative number multiplied by a postive number.
2. You can't factor 7, so 7x times x.
(7x−9)(x+2)
The correct answer is D.
If you look at the equation you can see that the line crosses at the points
(1,5) and (-2, -4). Use this set of ordered pairs to find the slope.
(-4-5)/(-2-1) = (-9/-3) = 3
The use the point-slope formula and fill in the ordered pair (1,5) with the slope.
y - 5 = 3( x - 1)
Answer: 4 days.
Explanation: Keep dividing 100 in half until you get a number less then 10 (10 percent becuase anything out of 100 can be a percentage).
You woukd have to divide 4 times to get to a number less than 10, in that case it would be:
100/2 = 50
50/2 = 25
25/2 = 12.5
12.5/2 = 6.25
6.25 would be the percent of the bunny left on the 4th day, the 4th day also being the day where less than 10 percent of the bunny is gone.

2a - b....a = 2 and b = 3
2(2) - 3 =
4 - 3 =
1
Answer:
B
Step-by-step explanation:
The answer is B because the slope is and there is no y- intercept
