Answer:

C) (2, -5).

Step-by-step explanation:

Convert to vertex form:

3x^2 - 12x + 7

= 3(x^2 - 4x) + 7

Completing the square:

= 3[ (x - 2)^2 - 4)] + 7

= 3(x - 2)^2 - 12 + 7

= 3(x - 2)^2 - 5.

Comparing with the general form

a(x - b)^2 + c we see that the vertex is (b, c) = (2, -5).

What is the measure of angles 1, 2, and 3?

stellarik [79]

Answer:

1= 70

2= 65

3= 95

For 1, just solve 180-(65+45) and then for 2, subtract #1 and 45 from 180. Then just solve for #3 by using 180-(#2+20)

Suppose you are explaining to a friend who missed class how to solve equations. Explain, in complete sentences, the steps necess

pashok25 [27]

Answer:

First, take x off of both sides making it: “5 -4 = 3 + 10”

Then subtract 3, making it “3(-7) = 10”

Then do 3 multiply 3 by -7, getting -21 = 10

that is how you would find out the equation is false
