Change this equation, in standard form, to slope-intercept form: 2x + 3y = 18
Mandarinka [93]

Answer:

y = -2/3 + 18

Step-by-step explanation:

2x + 3y = 18       -----    here is the equation...

-2x          - 2x     -----    bring the 2x to the other side

3y = -2x + 18      -----    now you have to divide everything by 3 to get y by itself

y = -2/3 + 18       -----    Done!

in a history class, the girl to boy ratio is 9 to 5. if there is a total of 70 students how many boys is there
DedPeter [7]

Answer:

25 boys.

Step-by-step explanation:

To solve this problem, first add the two parts of the ratio. 9 + 5 = 14. Then divide 70 by 14 to get 5. Since the total is 5 times the ratio total, multiply both sides of the ratio by 5. The result is 45 : 25. If you add them together, you get a total of 70. Therefore, there are 25 boys in the class.

Part a) In 35 minutes, 25 number of pages have been read.

Part b) There is positive association between time and the number of pages being read

Step-by-step explanation:

Part a) What is the meaning of the point (35,25)

35 is the value of x-axis and 25 is the value of y-axis

x-axis represent Time(minute) while y-axis represent Number of pages read

So, in 35 minutes, 25 number of pages have been read.

Part b) Is the association between time and number of pages positive or negative? state the association in terms of variables.

Association is positive if increasing one variable, other variable is also increasing.

Association is negative if increasing one variable, other variable is decreasing.

In the given graph, the association is positive. Increasing the time, the number of pages being read are also increasing.

if time is 20 minutes, number of pages read are 12.5. if time is 25 minutes then number of pages read are 17

So, there is positive association between time and the number of pages being read.
