Step-by-step explanation:
x - y = 1
rearrange for y = mx + b
-y = -x +1
y = x - 1
crosses the y axis at (0, -1)
y = -1 when x = 0
x = 1 when y = 0

1About one-half of the students are more than 55 inches tall.
2On average, the students are 46 inches tall.
3On average, the students are 55 inches tall.
4About one-half of the students are more than 46 inches tall.
(there is more than one answer)
Answers
Answer:
Below in bold.
Step-by-step explanation:
The mean is 55 therefore, by definition:
On average the students are 55 inches tall.
The median is the middle ( or the average of 2 middle) value when the data is arranged in order.
So as the media is 46 inches about half are more than 46 ins tall.

Viktoria knows that it is impossible to remove a red marble from her bag that has no red marbles in it. if she reaches into the bag and pulls out a marble without looking, what is the probability that the marble will be red? 0 startfraction 1 over 11 endfraction three-fourths 1
Answers
Because there are no red marbles on the bag, we will see that the probability is zero.
How to find the probability?We want to find the probability that the marble will be red. Viktoria knows that her bag has no red marbles, then it is impossible to get a red marble.
The probability of an impossible event is 0 (suppose that there are 10 marbles in the bag, we have a probability of 0 out of 10 of getting a red marble).
Then we can write the probability as P = 0.

Beth took out a loan at an annual compound interest rate of 30%.After 2 years she owes a total of £8112.What was the original amount that Beth Borrowed.Give your answer to the nearest £1
Answers
now, we don't have a compounding period above, so we're assuming the amount is compounding annually.
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\dotfill &\pounds 8112\\ P=\textit{original amount deposited}\\ r=rate\to 30\%\to \frac{30}{100}\dotfill &0.30\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &2 \end{cases}[/tex]

A discounted concert ticket costs $14.50 less than the original price p. You pay $53 for a discounted ticket. Write an equation that can be used to find the original price.
Answers
Answer:
p - 14.5 = 53
Step-by-step explanation:
The original price is p.
The discounted price is $14.50 less than p, or $14.50 subtracted from p. The discounted price is p - 14.5.
The discounted price is $53
Equation:
p - 14.5 = 53

Halve the second term and square it
3(x + 4)² -24 -3(4)² = 0
simplify the answer
3(x + 4)² -72 = 0
add 72 on both sides
3(x + 4)² = 72

(x + 4)² = 24
square root both sides

We have to show the amount in fraction that Paula spent during the following semester,
they spent for tuition = $2,500 = × 100

= 69.44%
they spent for rent = $650 = × 100
= 0.1806 × 100
= 18.06%
they spent for food = $430 = × 100
=0.1194 × 100
= 11.94%
they Spent in tuition, rent and food = 2,500 + 650 + 430 = $3580

Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero. Which statement must be true?
The pool must have been empty for the entire interval.
The pool must have been the same depth at the start of the interval as it was at the end of the interval.
The pool must have been deeper at the end of the interval than it was at the start of the interval.
The pool must have been more shallow at the end of the interval than it was at the start of the interval.
Answers
The pool must have been the same depth at the start of the interval as it was at the end of the interval, option second is correct.
What is the average rate of change?Finding out how much something changes over time is what the average rate of change is all about.
We have Lionel computed the average rate of change in the depth of a pool over a two-week interval to be zero.
As we know that the average rate of change can be calculated using:
= (Last quantity - starting quantity)/Time interval
The average rate of change, on the other hand, does not account for intermediate values, therefore you can't draw any conclusions about them.
In the given problem:
The average rate of change in depth = (Last quantity - starting quantity)/2
0= (Last quantity - starting quantity)
Final depth = Initial depth
Thus, the pool must have been the same depth at the start of the interval as it was at the end of the interval, option second is correct.

The rate of change is $27 per month if the change in y values is 54 and change in x values is 2.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables.
From the data given in the table, we can find the rate of change per month:
To find the rate of change:
= change in y/ change in x
= (138-84)/(4-2)
= 54/2
= 27 per month
Thus, the rate of change is $27 per month if the change in y values is 54 and change in x values is 2.

The points (2, -2) and (0, -1) lies on the inverse of the function y = (-x -2)/2 if the function is y = -2x - 2 option (C) and (E) are correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
In the graph, a linear equation is represented.
We can find the function of linear equation from the two points:
(-1, 0) and (0, -2)
x/-1 + y/-2 = 1
2x + y = -2
y = -2x - 2 ..(1)
From the equation, first take subject as x and find the value of x
2x = -y -2
x = (-y -2)/2
Replacing x→y and y →x
y = (-x -2)/2
The inverse of a function:
y = (-x -2)/2
Points (2, -2) and (0, -1) lies on the inverse of the function(refer to attached picture)
