Answer:
3, -8 , 11.
Step-by-step explanation:
f(x) = (x - 3)(x + 8)(x - 11)
Finding the zeros:
(x - 3)(x + 8)(x - 11) = 0
x - 3 = 0 gives x = 3.
x + 8 = 0 gives x = -8.
x - 11 = 0 gives x = 11.
The answer is 10, so it would be C
Answer:
x = 11
Step-by-step explanation:
10x = 4x + 66
10x - 4x = 66
6x = 66
x = 66/6
x= 11
Whole numbers are the part of the number system in which it includes all the positive integers from 0 to infinity. It is false every whole number is a natural number.
Answer:
<em>(18 , - 10) </em>
Step-by-step explanation:
5x + 4y = 50 .... <em>(1)</em>
x + 2y = - 2 ... <em>(2)</em>
Solve (2) for "x"
x = - 2y - 2 .... <em>(3)</em>
(3) ----> (1)
5(- 2y - 2) + 4y = 50 ⇔ - 6y - 10 = 50 ⇒ <u><em>y = - 10</em></u> .... <em>(4) </em>
(4) ----> (2)
x + 2(- 10) = - 2 ⇒<u><em> x = 18</em></u>
<em>(18, - 10)</em>
