Enter an equation in standard form to model the linear situation.
A bathtub that holds 28 gallons of water contains 18 gallons of water. You begin filling it, and after 5 minutes, the tub is full.
prove that for any natural value of n the value of the expression (n+2)^2-(n-2)^2 is a multiple of 8.
Answer:
Se below
Step-by-step explanation:
Simplifying, using formula a^2 - b^2 = (a +b)(a - b)
(n + 2)^2 - (n - 2)^2 =(n + 2 + n - 2)(n + 2 - n + 2) =2n(4) =8nAs we see the resulting expression is multiple of 8

2. 7 1/2 feet below sea level or -7 1/2 feet
3. It would stop on the 17th floorl
Step-by-step explanation:
2. You subtract 20 1/2 by 28 to get your answer. Flipped around, 28 - 20 1/2 is 7 1/2 so back to the right way would be -7 1/2 or 7 1/2 feet below sea level.
3. 23 + 5 = 28
28 - 14 = 14
14 + 3 = 17
So the 17th floor would be the answer.

Answer:
Y=1/2x-2
Step-by-step explanation:
Two linear functions are displayed. Function One is represented by the graph:
The second linear function is y = -4x. Which statement is true about the slope of the two functions?
A) The slope of function one is positive and the slope of function two is negative.
B) Both functions have a negative slope.
C) Both functions have a positive slope.
D) Both functions have the same slope.
Answer:
Option A
Step-by-step explanation:
Function One is represented by the graph. We can see that the slope of the First Function is positive because the formula of slope is
[tex]Slope=\frac{Change\ in\ y}{Change\ in\ x} \\\\[/tex]
And we can see that in the graph the change in y and change in x are both positive as the function is increasing because if we see the graph closely,
When x = 1 the value of y = 2 and when x = 2 the value of y = 4 and when x = 3 the value of y = 6 so the values are increasing of x and of y hence the slope is positive and the value of slope is 2.
Now the Second Function which is y = -4x here the slope is negative because the slope-intercept form of the equation is .
[tex]y=mx+b[/tex]
and the second function is
[tex]y=-4x[/tex]
if we compare both these equations we get the value of m = -4 where m is also called the slope. So the slope of the second function is negative.
So
Option B is incorrect because the slope of the first function is positive
Option C is incorrect because the slope of the second function is negative
Option D is incorrect because the slope of the first function is 2 and the slope of the second function is -4
That leaves us with Option A which is correct, where we can see that the slope of the first function is positive and the slope of the second function is negative
Answer:
A) The slope of function one is positive and the slope of function two is negative.
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
We see that the 1st graph has a positive slope; as x increases, the y-value also increases. Therefore, the 1st graph must have a positive slope.
We are given the equation y = -4x as our second line. Using our y = mx + b form, we see that our slope m = -4. Therefore, the 2nd graph has a negative slope.
Our answer choice then would be A, as it is the only one that matches the descriptions.

In the summer, the Thomas family enjoys picking berries together. It takes them 20 minutes to pick 3 baskets of berries.
Complete the table.
Answer:
the numbers 20, 60, 80, and 120 go on the x axis
the numbers, 3, 9, 12, and 18 go on the y axis
so you go to 20 on the bottom and go up to number 3
60 go up to number 9
80 go up to number 12
120 go up to number 18

A college student is looking for a data plan for her cell phone. She has found an option that offers a 2 gigabyte monthly allowance for data.
The monthly cost of this plan can be represented by function C, defined by:
C(x) = 30x + 5, where x is the gigabyte of data used over the monthly allowance.
Find C(0.7)
Select the correct answer as well as the correct explanation for the situation.
Group of answer choices
A. C(0.7)= 26 This means the plan costs $26 a month.
B.vC(0.7)= 26 This means that the cost would be $26 if she uses 0.7 gigabytes over the 2 gigabytes allowance in a month.
C. C(0.7) = 50 This means that the cost would be $50 if she goes over the 2 gigabytes monthly allowance.
2=1-2=2
+12-14= so this is the total boos you have 900=500
