What is the vertex for the following quadratic? f(x)= 2x^2-12x+16

Mathematics

Answer:

(3, -2)

Step-by-step explanation:

To find the vertex, put the equation into vertex form by completing the square

2(x^2 - 6x) + 16  [pulling out the 2]

2(x^2 - 6x + 9) - 18 + 16 [completing the square, you subtracted 2*9 = 18 so you also add 18]

2(x - 3)^2 - 2 [simplify the equation]

vertex is (3, -2)

What is the slope of the line?<br> y + 1 = 3(2x - 4)
Alexeev081 [22]

Answer: 6

Step-by-step explanation:

Let's start by getting the equation to slope intercept form

First simplify

y + 1 = 3(2x - 4)\\\\y+1=6x-12

Then get y by itself

y+1-1=6x-12-1\\y=6x-13

In slope intercept form y=mx+b, m is the slope

In this case the slope is 6

Britney paid $4.50 for two mangoes and one bag of grapes. Finn paid $9.25 for three mangoes and two bags of grapes. Britney and
docker41 [41]
B. 4.5=2m+g
f. 9.25=3m+2g

1.25=m

sub

b. 4.5=2(1.25)+g
f. 9.25=3(1.25)+2g

b. 4.5=2.5+g
f. 9.25=3.75+2g

minus 2.5 from both sides on the b. equaion and minus 3.75 from both sides on the f. equation

b. 2=g
f. 5.5=2g

divide both sides of f. equation by 2

b. 2=g
f. 2.75=g

2.75-2=0.75
finn paied $0.75 more for a bag of grapes
