Answer:

discriminant = 120

2 real roots ( or 2 x intercepts)

Step-by-step explanation:

f(x) = -7x^2 +8x+2

The discriminant is

b^2-4ac

Where ax^2 +bx+c

so a = -7  b = 8 and c =2

(8)^2 -4(-7) *(2)

64 +56

120

If the discriminant is >0 we have 2 real roots

If the discriminant =0 we have 1 real root

If the discriminant <0 we have 2 complex root ( or no real roots)

F(x) = x2 − 8x + 15 g(x) = x − 3 h(x) = f(x) ÷g(x) The domain of h(x) is
Sphinxa [80]

Answer:

{x | x ≠ 3}

Step-by-step explanation:

f(x) / g(x) = x^2 - 8x + 15 / (x - 3)

= (x - 5)(x - 3) / (x - 3) = h (x)

The domain is {x | x ≠ 3)

(because h(x) has no value when x = 3:-the denominator  x-3 becomes zero when x = 3)

One container of ice cream holds 9 scoops of ice cream. One package of ice cream cones has 12 cones. We want to make the fewest
attashe74 [19]

Answer:

1.  There will be 4 ice cream containers and the number of ice cream cone package is 3.

2.  will be able to make 36 ice cream cones and this is the fewest number of ice cream cones.

Step-by-step explanation:

  • One container of ice cream holds 9 scoops of ice cream.
  • And, one package of ice cream cones has 12 cones.
  • we have to find the least common multiple of 9 and 12 which is 36 and there must be 36 ice cream scoops and 36  ice cream cones.
  • So, there will be  36/9 =3 ice cream containers.
  • and the number of ice cream cone package is 36/12=3
  • That gives you your answer
