There are 2 terms, and terms are the numbers used in the problem, like 20x, and 9y.
Since they come with an unknown variable, you would count 20x as ONE term, and 9y as the SECOND term.
Hope this helps ;)

A movie theater offers a reward program that charges a yearly membership fee and a discounted rate per movie ticket. The total c

Answer:

$y=5x+15$

Step-by-step explanation:

Since this situation is a linear relationship between the number of movies and the total cost, we need to determine the slope of the line given our two ordered pairs $(x_1,y_1)\rightarrow(5,40)$ and $(x_2,y_2)\rightarrow(12,75)$ :

$m=\frac{y_2-y_1}{x_2-x_1}\\ \\m=\frac{75-40}{12-5}\\ \\m=\frac{35}{7}\\ \\m=5$

Thus, our equation so far is $y=5x+b$ . Next, we need to find our y-intercept, $b$ , which represents our flat fee. We do so by using one of our original given ordered pairs:

$y=5x+b\\\\40=5(5)+b\\\\40=25+b\\\\15=b$

Therefore, our final equation for the function is $y=5x+15$

The value of t∗ for a 95% confidence interval when there are 10 pieces of data is:

Anarel [89]

Answer:

The t-critical value for 95% confidence interval is ±2.2621

Step-by-step explanation:

We are given the following information in the question:

Sample size, n = 10

Alpha, α = 0.05

We have to find the value of t-critical at 95% confidence interval.

Degree of freedom = n - 1 = 9

$t_{critical}\text{ at degree of freedom 9 and}~\alpha_{0.05} = \pm 2.2621$

The t-critical value for 95% confidence interval is ±2.2621

I dont know functions

Irina-Kira [14]

Answer:

6, -8

Step-by-step explanation:

You need to find out the possible values of which X cannot equal

In fractions the only way that's possible is if the denominator= 0

Because everything in the denominator is being mulitplied this is pretty simple

We need either parantheses to equal 0

so we take them and solve for 0

we have

x-6= 0

x=6

x+8=0

x= -8
