A direct variation function contains the points (–9, –3) and (–12, –4). Which equation represents the function?
Natasha_Volkova [10]
First, find the slope between the two points. 
Slope = y2-y1 / x2-x1
-4+3/ -12+9
-1/-3
1/3 is the slope of this equation. 
You do not have to go any further to find b or the y-intercept because it appears that b or the y-intercept is 0 in this case. 
y= 1/3x or in other words y= x/3

samantha is making punch for a class picnic. there are 25 students in her class. Samantha uses 1 gallon 2 quarts of orange juice
Alex_Xolod [135]

Answer:

  • 4 gallons
  • yes

Step-by-step explanation:

A quart is 1/4 gallon, so the total of liquid ingredients for the punch is ...

  (1 2/4 gal) +(3/4 gal) +(1 3/4 gal) = 2 8/4 gal = 4 gal

Samantha made 4 gallons of punch.

__

1 cup is 1/16 gallon, so 2 cups each for 25 students requires ...

  (1/16 gal)(2)(25) = 50/16 gal = 3 1/8 gal

Samantha made more punch than that, so there will be enough for 2 1-cup servings for each student.

Identify the vertex of y = x^2 + 4x + 5
docker41 [41]

Answer:

D. (-2,1)

Step-by-step explanation:

we have

y=x^2+4x+5

This is the equation of a vertical parabola open upward The vertex represent a maximum

Convert the quadratic equation in vertex form

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

where

(h,k) is the vertex

Complete the square

y=(x^2+4x+2^2)+5-2^2

y=(x^2+4x+4)+5-4

y=(x^2+4x+4)+1

Rewrite as perfect squares

y=(x+2)^2+1

The vertex is the point (-2,1)
