Answer: 
pages per hour.
Step-by-step explanation:
For this exercise it is important to know that, by definition, Direct variation equations have the following form:
Where "k" is the constant of variation.
Therefore, it is a straight line that passes through the origin.
In this case, given the graph attached in the exercise, you can follow these steps in order to find the constant of variation:
Step 1: You need to choose any point on the line. Let's choose the point (5,4).
Step 2: Now you must ubstitute the coordinates of that point into . Then:
Step 3: Finally, you must solve for the Constant of variation "k", in order to find its value. Therefore, you get that this is:
Answer:
1. rhombus
2. trapezoid
3. rectangle
Step-by-step explanation:
Step 1
Given;
Required; Find the equation of a line that goes through the point ( 1,- 6 ) and is perpendicular to the line: y = (1 / 8)x - 9
Step 2
For perpendicular lines, the relationship between the slopes is;
The y-intercept is found thus;
Answer; The required equation will be;
It is -7.. To get from negative 10 to negative 17.. U gotta add -7
For the answer to the question above, we'll have to use the formula for velocity which is v =<u> d
</u> t and d = vt
Since the total distance is given, therefore we can get the time and it will look like this.
220t + 250t = 1880
<u>470t</u> = <u>1880
</u>470 470
the problem indicates that the train runs 250kph
Let's substitute:
d = 250(4)
the distance traveled by Lian is 1000km
<u>
</u>
