Answer:
(C) no solutions
Step-by-step explanation:
If you multiply the first equation by 2, you get ...
2x +2y = 4
When you compare this to the second equation ...
2x +2y = 8
you realize there are <em>no values of x and y that can satisfy both equations</em>. There are no solutions.
Answer:
f(x) = x³ - 5x² - 9x + 45
Step-by-step explanation:
Given x = a, x = b are the zeros of a polynomial, then
(x - a), (x - b) are the factors and f(x) is the product of the factors.
Here the zeros are x = - 3, x = 3 and x = 5, thus
(x + 3), (x - 3) and (x - 5) are the factors and
f(x) = (x + 3)(x - 3)(x - 5) ← expand the first pair of factors using FOIL
= (x² - 9)(x - 5) ← distribute
= x³ - 5x² - 9x + 45
Take the number (63) and then divide it with 100, this gives you 1%. Then you want to multiply with with 15 in order to get 15%. The answer becomes:
Answer:A
Step-by-step explanation: due to the all being divisible by 4
