See each answer below.
1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.
2) Dividing by 3 and taking the square root gives an answer of 0.
3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.
4) Divide by 4 and then take the square root. You have positive or negative 5/2.
Answer:
A) slope = 2, y-intercept = -6
B) slope = -4, y-intercept = 6
Step-by-step explanation:
A) y = 2x - 6
The equation for a line is y = mx + b, where <em>m</em> represents the slope, and <em>b</em> represents the y-intercept. So, to find the slope and y-intercept, all we have to do is look at the line's equation.
Here, the <em>m </em>is 2, so the slope is 2
The <em>b</em> is -6, so the y-intercept is -6
B) y = -4x + 6
Here, the <em>m</em> is -4, so the slope is -4
The <em>b </em>is 6, so the slope is 6
You would graph the equation y = 4x + 6 by plotting a point at the y-intercept of the line, which would be 6. Then, for every time you move one space to the right, you'd plot a point four spaces up to show the slope of four.

Answer:
D. ax-b<-c or ax-b>c is the correct answer.
Step-by-step explanation:
Based on the responses, the significance level, and the p-value, we can conclude that the response proportions are not the same for the countries.
<h3>What can be concluded about the response proportions for these countries?</h3>
The null hypothesis is that the response proportions are the same. The alternate hypothesis is that the response proportions are not the same.
The sample size is large enough for a Chi-Square test to be used because the expected counts are all greater than 5.
Running a Chi-Square analysis shows that the P-value to be 0.000.
The P-Value is less than the significance level of 0.01 so the null hypothesis is rejected. This means that the alternate hypothesis of the response proportions not being the same is true.
