Well you could count by threes and Fives and see your answer, 3,6,9,12,15, and so on and fives 5,10,15 and you have one match. 18, 21, 24, 27, 30 and 20, 25, 30. Two matches. They will blink at the same time about six times.
Answer:
The answer is B. Two Foci, hope this helps! :)
Answer:
-1
Step-by-step explanation:
are you sure this is the right equation ? it would mean that the more toppings the cheaper the ice cream.
but as it is written, the slope is -1.
the slope of a line is always the factor of the variable in the equation.
it is the ratio of y/x indicating how many units y is changing for a given change of x.
in our example here, if x changes 1 unit to the right (+1), then y changes 1 unit down (-1).
so, -1/+1 = -1
Answer:
The answer to your question is letter C
Step-by-step explanation:
With zeros 1, 2 and -5
Process
1.- Equal the zeros to x
x₁ = 1 x₂ = 2 x₃ = - 5
x₁ - 1 = 0 x₂ - 2 = 0 x₃ + 5 = 0
2.- Write the roots as a product
(x - 1)(x - 2)(x + 5)= 0
3.- Multiply the zeros
(x - 1)(x - 2) = x² - 2x - x + 2
Simplify = x² - 3x + 2
(x + 5)(x² - 3x + 2) = x³ - 3x² + 2x + 5x² - 15x + 10
Simplify like terms and result
= x³ + 2x² - 13x + 10
