Answer:

The value of slope m = -1

Step-by-step explanation:

x = -2 + 4t

and y = 1 + 4t

Solving the both equations

x +2 = 4t

=> t = (x+2)/4     eq(1)

y-1 = 4t

=> t = (y-1)/4      eq(2)

Putting eq(1) = eq(2) as left hand side of both equations are same

(x+2)/4 = (y-1)/4

Cross multiplying

4(x+2) = 4(y-1)

4x + 8 = 4y -4

4x +4y = -4 -8

4x + 4y = -12

4(x+y) = -12

x+y = -12/4

x+y = -3

y = -x -3

The slope intercept form of line is:

y = mx + b

where m is the slope. Comparing with y = -x-3

The value of slope m = -1

Answer:

C

Step-by-step explanation:

A modified box plot does not include the outliers in the whiskers, instead they are points outside of the whiskers

5,25,33,34,34,37,37,40,42,45,45,46,46,49,73

This data has 2 outliers 5 and 73 so we have 2 choices for a modified box plot D or D

The lowest value outside of the outliers is 25 , so C would be the logical choice

D has the lower end of the whisker too close to the outlier

babymother [125]

Answer:y=5x+30

Step-by-step explanation:

The y-intercept is 30 so it is y=?+30

Then the x changes value at a constant rate of 5

So... it is y=5x+30

HELP ME!!! Then I will help you on a question.
Firlakuza [10]

Answer:

$150

Step-by-step explanation:

Let the account earns 5% APR as simple interest for the invested principal.

Now, the formula of simple interest gives that,

A = P(1 + \frac{rt}{100}), where A is the final amount, P is the principal amount invested, r is the % of interest and t is the number of years for which the principal is invested.

So, the interest earned will be given by, I  = P \times \frac{rt}{100}

Hence, in our case, $300 is invested for 10 years at a simple interest of 5%. So,  I = 300\times \frac{5 \times 10}{100} = 150 dollars.

Therefore, the amount of interest earned will be $150. (Answer)
