Answer:
(-3+√17 )/2. or( -3-√17)/2
hope you got it
7/8 owns bike
1/8 dont
difference is 6/8
6/8= 72
96 students were surveyed, if you solve that equation^
0 = -5n - 2n
0 = -7n <em>|divide both sides by (-7)</em>
<u>n = 0</u>
Answer:
x = -8 and x = 4
Step-by-step explanation:
given
f(x) = (x+8) (x - 4)
recall that at any point on the x-axis, y = 0 [i.e f(x) = 0]
hence to find where the graph crosses the x-axis, we simply substitue f(x) = 0 into the equation and solve for x
f(x) = (x+8) (x - 4)
0 = (x+8) (x - 4)
Hence
either,
(x+8) = 0 ----> x = -8 (first crossing point)
or
(x-4) = 0 ------> x = 4 (second crossing point)
Hence the graph crosses the x-axis at x = -8 and x = 4
