Identify the linear term in the function of y = 2x2 − 5x − 12

MakcuM [25]

Answer:

The linear term is -5x

Step-by-step explanation:

The linear term is the term that has the degree equal to 1.

The given function is

y = 2x^2 − 5x − 12

here 2x^2 = quadratic term i.e having degree 2

-5x = linear term i.e having degree 1

-12 = constant

so, The linear term is -5x

Which is the standard form of y-3=2(x-4) <br> (A) Y=-2x-5<br> (B)2x-5<br> (C)2x+y=-5<br> (D)2x-y=5

pantera1 [17]

y -3 = 2(x-4)

Use distributive property on the right side:

y - 3 = 2x -8

Add 3 to both sides:

y = 2x -5

The answer is A.

What is the rotation that translates AWXY to AW'X'Y'? Be sure to give the degre

oee [108]

The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation. See the attached image for details.

<h3>What is a rotation in math?</h3>

Rotation in math refers to the change in the angle of a geometric shape around a central axis on a point on the geometric plane such that it's original coordinates are modified but it's size or shape.

Hence, it is correct to state that The rotation that that translates AWXY to AW'X'Y' is a 45° anticlockwise rotation.
