Answer:
Step-by-step explanation:
The roots are really just what x is when the equation is equal to zero. So, an equation with these roots would look like this:
(x+3)(x-4/5)=y
however, this is not standard form. To get standard form we will need to expand the equation using FOIL.
x^2+3x-4x/5-12/5=
x^2+11x/5-12/5
and that would be your answer.
This stuff is a bit tricky and it get annoying with those pesky fractions. If you have any questions just comment.
your answer is B= 12 your welcome :)
Answer:
20%
Step-by-step explanation:
If you divide 32 out of 40, you will get .8. Multiply that by 100 and you will get 80%. The question asks for the percentage of <em>incorrect</em> ones, so subtract 80 out of 100 and you will get 20%.
She got 20% of the words incorrect.
Answer:
x = 2
Step-by-step explanation:
12/7.5 = 1.6
x+6/2x+1 = 1.6
to find the value of x :
x + 6 = 3.2x + 1.6
x - 3.2x = 1.6 - 6
- 2.2x = - 4.4
- x = - 4.4/2.2
- x = - 2
x = 2
