4 0

Answer:

Hence, the roots of the polynomial equation are:

-2, 1, 4

Step-by-step explanation:

We are asked to find the roots of the polynomial equation:

We can also equate this equation to y to obtain a system of equation as:

and

Hence, the roots of the polynomial; equation are the x-values of the point of intersections of the graph of the system of equations.

Hence, the point of intersection of the two graphs are:

(-2,4), (1,-5) and (4,40)

Hence, the roots of the polynomial equation are:

-2, 1, 4

A quadratic function f is defined by /«) = (x - 7)(x + 3).
lesya692 [45]

Answer:

Step-by-step explanation:

The two x intercepts are

x -  7 = 0

x = 7

x + 3= 0

x = - 3

The y intercept is just - 7 * 3 = - 21

To prove this  more formally

f(x) = (x - 7)(x + 3)

f(x) = x^2 - 7x + 3x - 21

f(x) = x^2 - 4x - 21

Laura, Scott, and Joe served a total of 104
umka21 [38]

9514 1404 393

Answer:

  • Joe: 57
  • Scott: 19
  • Laura: 28

Step-by-step explanation:

Let s represent the number of orders Scott served. Then we have Joe served 3s, and Laura served (s+9). The total of orders served is ...

  3s +s +(s +9) = 104

  5s = 95 . . . . . . . . . . . subtract 9 and collect terms

  s = 19 . . . . . . . . . divide by 5

  3s = 3×19 = 57

  s+9 = 19+9 = 28

Joe served 57 orders, Scott served 19, and Laura served 28 orders.
