I don't understand what you mean by 'Why it doesn't show'
Answer:
(x-10) (x+1) =0
x=10 x=-1
Step-by-step explanation:
x^2 -9x-10 =0
Factor
What two numbers multiply to -10 and add to -9
-10*1 = -10
-10+1=-9
(x-10) (x+1) =0
Using the zero product property
x-10 = 0 x+1=0
x-10+10=0+10 x+1-1=0-1
x=10 x=-1
These are the x intercepts
For this question, you would simply plug in a 2 wherever you see an x and plug in a 6 wherever you see a y. Then you simplify the expression.
3(2) + 8(6) - 7
6 + 48 - 7
47
Hope this helps!
