Answer:
x² -3x - 54
Step-by-step explanation:
given roots of a polynomial are 9 and -6
this means that (x-9) and (x+6) are factors of the polynomial.
To get the polynomial with the least degree, simply multiply the two factors to obtain a quadratic expression (degree 2)
(x-9) (x+6)
= x² + 6x -9x -54
= x² -3x - 54
Answer:
the best way to solve this is to have graph paper, so your numbers and points align. I have a model attached. the first point is hours slept 8. so on your graph go to 8 then across to 83, which is the test score. make a mark to represent this point. do this for all and it will create a line
Answer:
<u>4 hours</u>
Step-by-step explanation:
Equations :
Larry : <u>y = 20x + 90</u>
Barry : <u>y = 30x + 50</u>
Equate both to find the number of hours at which they both charge the same :
- 20x + 90 = 30x + 50
- 30x - 20x = 90 - 50
- 10x = 40
- x = <u>4 hours</u>
Answer:
c = 1
Step-by-step explanation:
9 x 1 + 1 = 10
Hope this helps!
Arjun should have divided both sides of the equation by 7 instead of multiplying.
