Step-by-step explanation:
Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below.
Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance.
Natasha uses the $25 off the repair cost coupon first. She then uses the 20% off the repair cost coupon on the remaining balance.

What is the equation of the line?
Answers
Answer: x = -9
Step-by-step explanation:
When you look at the line, you can see it's plotted on the x-axis. From there you know the solution will be equal to x. Since the line passes right through the number -9 on the x-axis line, the answer would be x = -9. The line is straight which means it has no y intercept which is why x is only equal to -9.

If there was only one government class, and Wes and Maureen were in that class of 38 students, what would be the probability that both Wes and Maureen would be selected as the two students to go to Washington? Is this still an example of independent events
Answers
The probability of an event is 1/19. Therefore, the given situation is not an independent event.
Given that, Wes and Maureen were in the government class of 38 students.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Total number of outcomes =38
Number of favourable outcomes = 2
So, probability =2/38
= 1/19
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.
The probability of an event is 1/19. Therefore, the given situation is not an independent event.

Answers
Answer:
x = 10.3
y = 5.8
Step-by-step explanation:
To find both x and y, you can use the formula [tex]a^{2}[/tex] + [tex]b^{2}[/tex] = [tex]c^{2}[/tex]
a and b would be the sides that touch the right angle
so to find x, you would do [tex]9^{2}[/tex] + [tex]5^{2}[/tex] = [tex]x^{2}[/tex]
this would be: 81 + 25 = [tex]x^{2}[/tex]
then add it and you get: 106 = [tex]x^{2}[/tex]
now do the square root of 106 to get: 10.3 = x
Now plug in your other values to get y: [tex]5^{2}[/tex] + [tex]3^{2}[/tex] = [tex]y^{2}[/tex]
do the same thing here: 25 + 9 = [tex]y^{2}[/tex]
add your numbers: 34 = [tex]y^{2}[/tex]
square root 34: 5.8 = y

The population of a town is 75 000 and decreases 15% each year. Complete the exponential function that models the population afterx years
f(x) = 75,000
Answers
Answer:
Step-by-step explanation:
This is an exponential function of the form:
[tex]y=a(1-r)^x[/tex] where a is the initial value and (1 - r) is the growth rate (which in our case is a decay, actually!). Our initial value is 75000 and our rate of change in the population is 15% or .15. Filling in our model:
[tex]y=75000(1-.15)^x[/tex] and simplifying:
[tex]y=75000(.85)^x[/tex] This turns out to be a decay problem because the value inside the parenthesis is less than 100%.
x is our time, so the model is as stated above.
