Think of quantitative observations as the quantity.

Quantitative observations involve measurements, numbers, or things you can count.
Example: The book is 12 inches long.

Qualitative observations are details about something NOT including numbers. Such as describing what it looks like with your senses.
Example: This book is blue.

I’ve been having trouble with these all week!

Answer:

Step-by-step explanation:

so you will move constant to the right side and change the sign. 72x=223-7

then you will subtract the numbers 72x=223-7 and that will give you 72=216

then you will divide both sides by 72 and that will give you

x=3 .

The following graph represents the distance a commercial airplane travels over time, at cruising speed and an altitude of 35,000

ANEK [815]

Answer:

see the explanation

Step-by-step explanation:

<u><em>The picture of the question in the attached figure</em></u>

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Let

x ----> the time in hours

y ----> the distance in miles

<em>Find the value of k</em>

For the point (4,2268)

$k=\frac{2,268}{4}=567\ mph$

The slope represent the speed of the airplane

so

The linear equation is

$y=567x$

Part 1 :

The point (0,0) represents the starting point of the aircraft, when the time and distance are equal to zero. The cruising starts when time t = 0.

Part 2 :

The point (4, 2268) represents the plane after 4 hours of cruise , and shows it has traveled a distance of 2268 miles after 4 hours

-1/2x+3y=-3 in slope intercept form

ElenaW [278]

Answer:

Step-by-step explanation:

Y = mx + b

-1/2 x + 3y = -3

3y = 1/2 x -3

y = 1/6 x - 1

Where slope m = 1/ 6and y intercept b = -1

Answer:

∠X in the pre-image will be equal to ∠L in the main image

Step-by-step explanation:

△LMN is the result of a reflection of △XYZ which means △LMN is the mirror image △XYZ

hence, the left of △XYZ will be equivalent to the right of △LMN and the right of △XYZ will be equivalent to the left of △LMN

Hence, ∠X in the pre-image will be equal to ∠L in the main image
