Step-by-step explanation:
The lowest value of x is about -8, which is greater than negative 10
Answer:
y = 0.5 (x^2 -2x + 16) has a y-intercept of 8.
Step-by-step explanation:
The x-coordinate of every y-intercept is zero. To determine which of the four quadratics given here has a y-intercept of 8, we need only substitute 0 for x in each; if the result is 8, we've found the desired quadratic.
O y = 0.5(x + 2)(x + 4) becomes y = 0.5(2)(4) = 4 (reject this answer)
O y = 0.5 (x - 2)(x + 8) becomes y = 0.5(-2)(8) = -8 (reject)
O y = 0.5(x2 -2x - 16) becomes y = 0.5(-16) = -8 (reject)
<em>O y = 0.5 (x2 -2x + 16) becomes y = 0.5(16) = 8 This is correct; that '8' represents the y-intercept (0, 8).</em>
Answer:
20
Step-by-step explanation:
to find the mean, it means to find the average.
steps:
first, you add up all the numbers.
then you divide that total number by the total number of numbers you have.
and that is ur answer!!
17+19+21+23=80 add up all numbers
80÷4=20 divide total by the amount of numbers
The average/mean is 20.
plz give brainliesttttt
