Answer:

Please check explanations

Step-by-step explanation:

Here, we want to interpret the meaning of the slope

The slope generally refers to the change in y values with corresponding change in x value

with respect to this question, we can see that the slope is negative

What this mean is that the rate of change in the level of oxygen measured in liters is decreasing with an increase in the time

This means that as more time elapses, more oxygen is used up leading to a decrease in the liters of oxygen present

IF THE TRIANGLES IN THE ABOVE FIGURE ARE PROPORTIONAL, WHATS THE LENGTH OF SIDE B?
Tema [17]
<h3>Answer: choice B) 36</h3>

=================================================

Explanation:

The vertical sides, when read from left to right, can be divided to get this fraction: 9/90

Following the same order and direction, we divide the slanting corresponding sides to get: b/360

The fractions we constructed are equal to one another, as the triangles are said to be proportional.

We have the fraction 9/90 = b/360

Lets cross multiply and solve for b

--------------------

9/90 = b/360

9*360 = 90*b

3240 = 90b

90b = 3240

90b/90 = 3240/90

<h3>b = 36</h3>

--------------------

A quick way to do this may be to notice how the jump from 9 to 90 is "times 10" so the jump from b to 360 is also "times 10". Think in reverse to divide 360 over 10 and we land on 36 as our answer. This line of thinking does not work as simple for all proportional problems.

What is the slope of the line through (2,-2)(2,−2)(, 2, comma, minus, 2, )and (9,3)(9,3)(, 9, comma, 3, )? Choose 1 answer: Choo
svp [43]

Answer:

A)  \frac{5}{7}

Step-by-step explanation:

Use the two-points formula for the slope of a line.

We know that the points (2,-2) and (9,3) are on the line. If (a,b),(c,d) are points on a line then the slope m is defined by the equation m=\frac{d-b}{c-a}. In this case, a=2,b=-2,c=9 and d=3 then the slope is m=\frac{3-(-2)}{9-2}=\frac{5}{7}.
