Answer:
The ordered pairs are;
(-1,1) and (-2,3)
Step-by-step explanation:
Here, we want to select which ordered pair is not a solution to the given equation
The one that will not be a solution will be a point at which if we insert the x-value into the equation, we do not get the y-value at that point
For (3,7
2(3) + 1 = 7
For 0,1
2(0) + 1 = 1
For (-1,1)
= 2(-1) + 1 = -2 + 1 = -1
This is wrong
(-3,-5)
= 2(-3) + 1 = -6 + 1 = -5
(-2,3)
= 2(-2) + 1 = -4 + 1 = -3
This is wrong also
Answer:
9
Step-by-step explanation:
Recall that the sum of all interior angles in a triangle is 180°, and that a flat-line is always 180°.
Check the picture below.
Hi!
Book has 481 pages, and she read 481 - 403 = 78 pages in 1,5 hours. We can calculate the rate in pages per hour like this:
78 pages in 1,5 hours
x pages in 1 hour
_________________
x = (78*1)/1,5
x = 78/1,5
x = 52
Shryia reads 52 pages per hour.
To find how long did it take her to read the entire book, we will divide the number of pages in the book by the rate of pages read in one hour, like this:
481/52 = 9,25
It took her 9,25 hours to read the entire book.
Hope this helps!
