Answer: (y-5)(y+3)
<em>// If the coefficient of the y^2 is 1 and equation has integer-solution, than 15 must be divisible to that solution. Fermat's Theorem consequence</em>
It's obvious that y=5 is solution.
<em>// If x1 and x2 are solution to quadratic equation, ay^2+bx+c, where a is 1, then x1*x2=c. Fermat's Theorem</em>
Divide equation by (y-5), If you cannot do this look for other obvious solutions.
Answer:
B
Step-by-step explanation:
(-5,4)
To get from B to A, the x value increases 5 and the y value increases 5, for every one unit increase in x, y also increases by 1. 1/5 of the way is 1/5 times 5 = 1. Just increase both x and y by 1 to get (-5, 4)
-6+1 = -5 = x and 3 + 1 = 4 = y (-5,4) is the point 1/5 of the way from B to A
Answer:
The number of rainfalls is
The answer to the second question is no it will not be valid this because from the question we are told that the experiment require one pH reading per rainfall so getting multiply specimens(used for the pH reading) from one rainfall will make the experiment invalid.
Step-by-step explanation:
from the question we are told that
The standard deviation is
The margin of error is
Given that the confidence level is 95% then we can evaluate the level of significance as
Next we will obtain the critical value of from the normal distribution table , the value is
Generally the sample size is mathematically represented as
substituting values
The answer to the second question is no the validity is null this because from the question we are told that the experiment require one pH reading per rainfall so getting multiply specimens(used for the pH reading) from one rainfall will make the experiment invalid
It’s B because a discount takes money off a item
Answer:
13 1/8
Step-by-step explanation:
3/8-(-51/4)
Subtracting a negative is like adding
3/8 + 51/4
get a common denominator
3/8+ 51/4 *2/2
3/8 + 102/8
105/8
8 goes into 105 13 times with 1 left over
13 1/8
