mestny [16]

Answer:

charges for the first hour = $7.55

charges for each additional hour = $1.55

c = 1.55h + 7.55

Step-by-step explanation:

Let

x = charges for the first hour

y = charges for each additional hour

x + 2y = 10.65 (1)

x + 5y = 15.30 (2)

Subtract (1) from (2)

5y - 2y = 15.30 - 10.65

3y = 4.65

y = 4.65/3

= 1.55

y = $1.55

Substitute y = 1.55 into

x + 2y = 10.65

x + 2(1.55) = 10.65

x + 3.10 = 10.65

x = 10.65 - 3.10

= 7.55

x = $7.55

c = 1.55h + 7.55

Consider the polynomial equation x(x - 3)(x + 6) (x-7) -0. Which of the following are zoros of the
Black_prince [1.1K]

Answer:

The zeros are : 0, 3, -6, 7.

Step-by-step explanation:

Zeros of a polynomial is the values at which the polynomial becomes zero. They are also called the roots of the polynomial.

When (x - a)(x - b) = 0, we can say that either (x - a) = 0 or (x - b) = 0. At least one zero renders the whole equation to be zero.

Now, we are given that: x. (x - 3). (x + 6). (x - 7) = 0

⇒ To make the equation zero, at least one of the following should be true:

x = 0

x - 3 = 0  ⇒ x = 3

x + 6 = 0 ⇒ x = -6

x - 7 = 0 ⇒  x = 7

Therefore, x can take any one of the above values and that would make the polynomial zero.
