Answer:

t=0.4082

Step-by-step explanation:

so introduce unknowns mine are x for square foot and y for monthly rent and t as the coefficient

preferably arrange the square feet in ascending order with corresponding rent to see the trend

so the rent increases with increase in square footing therefore x is directly proportional to y

$x \infty y$

$x = ty$

take samples from your data eg x=400 y=980 and solve

Gennadij [26K]

Answer:

AB = PQ

Step-by-step explanation:

ABC = PQR

The angles are equal and the segments are equal

for the angles

A = P

B = Q

C = R

For the segments

AB = PQ

BC = QR

AC = PR

13. Find the smallest number which when divided by 21,28,36 and 44 leaves a

OleMash [197]

Answer:

2775

Step-by-step explanation:

Well of course since the problem is not restricted, the smallest number is 3. I'm almost sure that's not what you mean. The next smallest number is 2775. I found that using a programing language. I'm sure as well that does not satisfy the question, either.

I think you are intended to do this by finding the lowest common multiple and adding 3.

21: 3 * 7

28: 2 * 2 * 7

36: 2 * 2 * 3 * 3

44: 2 * 2 * 11

LCM = 2 * 2 * 3 * 3 * 7 * 11 = 2772

Now add 3 and the number you want is 2775

Does the equation y= -1/x represent a direct or inverse variation?

Bingel [31]

The equation y = -1/x represent a inverse variation

<u>Solution:</u>

Given, equation is $y = \frac{-1}{x}$

We have to find the relation between x and y

Now, for finding the relation we have to take two sets of values of x and y and substitute them in given equation.

$\begin{array}{l}{\text { Now, take } y=1 \rightarrow 1=-\frac{1}{x} \rightarrow x=-1} \\\\ {\text { Now, take } y=-1 \rightarrow-1=-\frac{1}{x} \rightarrow x=1}\end{array}$

If we observe, when y value is decreased from 1 to – 1, the value of x is increased from -1 to 1

Hence, the x and y varies inversely

15.) Match the graph with its equation.

Over [174]

Answer:

Step-by-step explanation:

first look at graph and figure out the slope and y - intercept

slope is 5/4 - change in y over change in x

y- intercept is -5

convert each equation to y = mx + b format

until you find the one that matches y = 5/4x - 5
