Answer:
B
Step-by-step explanation:
To find the x- intercepts let f(x) = 0 , that is
(x + 1)(x + 4) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x + 1 = 0 ⇒ x = - 1
The x- intercepts are (- 4, 0 ) and (- 1, 0 )
Solve both formulas to y=mx+b (slope intercept formula) where m=slope and b=y-intercept
y=-3/1x+-7
x-2y=-14
-2y=-14-x
y=7+1/2x
Start with the b variable so for problem 1 put a dot on 0,-7 and for problem 2 put a dot on 0,7
Then from -7 for problem 1 depending on whether the slope is negative or positive go down 3 and over right 1 therefore another point for problem one is marked, at 1,-10; for problem 2 up 1 and to the right 2; 2,8
For problem one connect the dots of 0,-7 and 1,-10
For problem two connect the dots of 0,7 and 2,8

Answer:
do 5 divede by 6
Step-by-step explanation:
1. Find the "opposite side," if the angle is 60 degrees and the hyp is 6:
opp opp sqrt(3)
sin 60 deg = ------- = -------- = ----------
hyp 6 2
Cross-multiplying, 2(opp) = 6sqrt(3), so that opp = 3 sqrt(3) (answer)
2. Use the Pyth. Thm. to find the "adjacent side:"
[3sqrt(3)]^2 + x^2 = 6^2, or 9(3) + x^2 = 36, or x^2 = 9, or x = 3.
The lengths of the legs of this 30-60-90 triangle are 3 and 3 sqrt(3).
check: Does 3^2 + [3sqrt(3)]^2 = 6^2?
Does 9 + 9(3) = 6^2? YES
