I think there is only one point x = -1.
Are you sure it's not x^2 + 1 = 0, if you had this equation the two points will be -1 and 1.
Or the equation was something like: x+1 =y?
If the equation is x+1=y.
First point: (-1,0)
Second point: (0,1)

Answer: 16
Step-by-step explanation:
From the question, we are informed that there are 25 markers in a bag: 5 red, 5 yellow, 5 blue, 5 green, 5 purple and that one marker is drawn out of the bag, then put back in.
The probability of picking a blue marker will be: = 5/25 = 1/5
Therefore, the number of times that a blue marker will be expected to be picked in 80 draws would be:
= 1/5 × 80
= 16 times
Answer:volume of regular pyramid = 3388 units³
Explanation:Volume of regular pyramid can be calculated using the following rule:
volume of regular pyramid =
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D)
* area of base * height
volume of regular pyramid =
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D)
* length * width * height
Based on the comment you added above, we have:
length = 11 units
width = 11 units
height = 84 units
Substitute with the givens in the above equation to get the volume as follows:
volume =
![\frac{1}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D)
* 11 * 11 * 84
volume = 3388 units³
Hope this helps :)
It is immensely important to go through all the details given in the question. Based on those details the answer to the question can be deduced.
Number of G.I. Joe in Betty's collection = 165
Number of G.I. Joe dolls Betty gave to Joe = 165 * (1/3)
= 55
Then the number of G.I. Joe dolls Betty have now = (165 - 55)
= 110
The
number of G.I. Joe dolls that were left with Betty after giving away
1/3 rd of the dolls was 110. I hope the answer is absolutely clear to
you. In future you can always use this procedure for solving similar
kinds of problems.
