Answer:

y = 10.50x + 7.50

Step-by-step explanation:

First find the slope

m = ( y2-y1)/(x2-x1)

   Add the two y values  to get the total y for the slope

y2 = 5.50+4 = 9.50  when x=2

y1 = 3.50+ 2.50 = 6  when x =1

m = ( 9.50-6/(2-1)

    3.50/1

  = 3.50

The slope intercept form is

y = mx+b  where m is the slope and b is the y intercept

y = 3.50x +b

Using the point ( 1,6)

6 = 3.50(1) + b

6 - 3.50 = 3.50+b-3.50

2.50 =b

y = 3.50x+2.50

We want 3 shipments

Multiply by 3

y = 10.50x + 7.50

Explain how to find the vertex of 2x^2+12x+16
Elina [12.6K]

The vertex form:

y=a(x-h)^2+k\\\\(h,\ k)-vertex

Use (a+b)^2=a^2+2ab+b^2\qquad(*)


2x^2+12x+16=2(x^2+6x)+16=2(x^2+2(x)(3))+16\\\\=2(\underbrace{x^2+2(x)(3)+3^2}_{(*)}-3^2)+16=2((x+3)^2-9)+16\\\\=2(x+3)^2+(2)(-9)+16=2(x+3)^2-18+16\\\\=\boxed{2(x-(-3))^2-2}\to h=-3,\ k=-2

<h3>Answer: (-3, -2).</h3>

Other method:

f(x)=ax^2+bx+c\\\\vertex:(h,\ k)\\\\h=\dfrac{-b}{2a},\ k=f(h)

We have

f(x)=2x^2+12x+16\\\\a=2,\ b=12,\ c=16

Substitute:

h=\dfrac{-12}{(2)(2)}=\dfrac{-12}{4}=-3\\\\k=f(-3)=2(-3)^2+12(-3)+16=2(9)-36+16=18-36+16=-2

<h3>Answer: (-3, -2).</h3>

If one quarter (25 cents) is 25% of a dollar, what percent is 23 cents?
Ugo [173]
You need to apply the same reasoning.
25 cents is 25% of a dollar because they are 25 out of 100, that is 25/100 = 25%
For 23 cents is exactly the same reasoning:
23 cents is 23% of a dollar <span>because they are 23 out of 100 cents, that is 23/100 = 23%</span>
