Mathematics
1 answer:
Law Incorporation [45]3 years ago

Answer:

(3, - 25 )

Step-by-step explanation:

Given a quadratic in standard form : y = ax² + bx + c : a ≠ 0

The the x- coordinate of the turning point is

x = - \frac{b}{2a}

Given

y = (x + 2)(x - 8) ← expand factors using FOIL

  = x² - 6x - 16 ← in standard form

with a = 1 and b = - 6, thus

x = - \frac{-6}{2} = 3

Substitute x = 3 into the equation for corresponding value of y

y = (3 + 2)(3 - 8) = 5(- 5) = - 25

turning point at (3, - 25 )

Can you help me with this one
exis [7]
5 is b and 1 is a
1 is A because just change the x value with the number in the table for x and see if y matches like
Y=-2x+6
Y=-2*1 + 6
4 =-2*1+6

And for 5
Day is x, y is depending on x and your going to add .4 to everything. But it’s growing .2 every day so it’s
Y=0.2x+0.4

I hope this helps you if I’m not right please tell me so if other people use those they know I’m wrong if I am. I don’t think so thou. If not please give me brainiest. Thank you!!
Have a nice night.

Allison has 6 blue pencils and 10 yellow pencils.sadie has 24 pencils that are either blue or yellow.the ratio of blue pencils t
sammy [17]
6 (Allison's number of blue) divided by 16 (Allison's total) is equal to x (Sadie's blue) out of 24 (Sadie's total).
So 6/16=3/8=x/24. So x=3*3, so Sadie's amount of blue pencils is 9. The rest of Sadie's pencils are yellow, so Sadie has 24-9=15 yellow pencils.
