Hi again!
x² + 8x - 20 = 0
Factorize the left side
(x - 2)(x + 10) = 0
Then set factors equal to 0
x - 2 = 0 or x + 10 = 0
x = 0 + 2 or x = 0 - 10
x = 2 or x = -10
Always,I am here to help!
Answer:
Option B is correct
The function h(x) = |x|
Step-by-step explanation:
Given the points (0, 0) , (-1 , 1) and (-2 , 2)
The absolute value of x i,e |x| will always gives the positive value of y
i.e y = |x|
For x = 0
y=|x| =|0| = 0
For x =-1
y= |-1| = 1
For x = -2
y = |x| = |-2| = 2
As you can see that for every value of x , we get the positive value of y;
therefore, the function which represents the condition is: y=h(x)=|x|
Hence, the given points lie on the graph of the function h(x) = |x|
The sum of angle AOB and angle BOC is equal tot he angle of AOC so
6x+5 +4x-2 = 8x+21
10x+3=8x+21
Subtract three and 8x from both sides
2x=18
Divide by two
x=9
Hope this helped!
