angles a and b are supplementary because they form a straight line

In this figure, ∠A and ∠B would be supplementary, or Choice B. This is because the angles comprise a straight angle.

Essentially, if you took away the line dividing angles A and B, then you would have a perfectly straight angle, which means that the angles are supplementary. Additionally, this means that their measures add to 180°.

The data set represents a month-to-month progression of gasoline prices over the course of several months in an unspecified city

mash [69]

Answer:

The correct option is a.

Step-by-step explanation:

The general form of a quadratic regression equation is

$y=ax^2+bx+c$ ..... (1)

Using graphing calculator we get

$a=-0.143393\approx -0.143$

$b=0.59525\approx 0.595$

$c=2.82964\approx 2.830$

Substitute these values in equation (1) to find the quadratic regression equation for this data set.

$y=-0.143x^2+0.595x+2.830$

Therefore the correct option is a.

When solving the equation which is the best first step to begin to simplify the equation ? -2(×+3)=-10?

andrezito [222]

Expand it first. -2(x+3)= -2x-6
-2x-6 = 10
-2x = 10+6
-2x = 16
-x = -8
x = 8
