Answer:

Graph B is a function

Step-by-step explanation:

We can use the vertical line test to determine if a relation is a function. If a vertical line passes through more than one point, the relation is not a function.

Graph A At x=-1 a vertical line will pass through 3 points, so it is not a function.

Graph B A vertical line does not pass through more than 1 point

Graph C At x=2, it will pass through 2 points so it is not a function

Todor was trying to factor 10x^2-5x+15. He found that the greatest common factor of these terms was 5 and made an area model: Wh

Answer:

The width of the area model is equal to

$(2x^2-x+3)\ units$

Step-by-step explanation:

we know that

The area of a rectangular model is given by the formula

$A=LW$ ----> equation A

where

L is the length

W is the width

we have

$A=10x^2-5x+15$

Factor the expression

$A=5(2x^2-x+3)$

substitute the value of the Area in the equation A

$5(2x^2-x+3)=LW$

In this problem

The greatest common factor of these terms is the length (L=5 units)

we can say that the width is equal to (2x^2-x+3)

therefore

The width of the area model is equal to

$(2x^2-x+3)\ units$

It’s not A or C. I think it’s D because of its positive slopes. If you have a graphing calculator, you can type this into y=

Hey there! :D

If m<A is the vertex, and it is isosceles, then the last two angles are equal.

All the angles in a triangle equal 180 degrees.

180-140= 40

40/2= 20

m<b= 20 degrees.

I hope this helps!
