It will take him 40 minutes to run 5 mile.

D) 40 minutes

Answer:

C) 40 minutes

Step-by-step explanation:

It takes Marcus 8 minutes to run a mile. In 40 minutes, Marcus would have ran 5 miles.

1 mile = 8 minutes

5 miles x 8 minutes = 40 minutes to run five miles

Solve for y.
y – (–19) = 25
a. –44
b. –6
c. 6
d. 44

Answers

y - (-19) = 25

First, simplify your brackets. / Your problem should look like: y + 19 = 25
Second, subtract 19 from both sides. / Your problem should look like: y = 25 - 19
Third, subtract 25 - 19 to get 6. / Your problem should look like: y = 6

Answer: C) y = 6

Solve the system using multiplication for the linear combination method.6x – 3y = 3
–2x + 6y = 14
What is the solution to the system?
(2, 1)
(2, –3)
(2, –1)
(2, 3)

Answers

If you would like to solve the system of equations, you can calculate this using the following steps:

6x – 3y = 3
–2x + 6y = 14     /*3
_________
6x – 3y = 3
–6x + 18y = 42
_________
-3y + 18y = 3 + 42
15y = 45
y = 45/15
y = 3

6x – 3y = 3
6x - 3 * 3 = 3
6x = 3 + 9
6x = 12
x = 12/6
x = 2

(x, y) = (2, 3)

The correct result would be (2, 3).

Give an example of a relation that is NOT a function and explain why it is not a function.I do not understand how to do this...please help its algebra.

Answers

The desired example is this: x=y^2
Because for each x>0 we have two different possible y values which means it is not a function anymore. a function should only maximum 1 y value for each x value.

You can see the above relation has multiple possible values for y because if we take x=1 then y can be -1 or 1.


Find the 60th term of the arithmetic sequence −29,−49,−69,

Answers

Answer: The 60th term of the arithmetic sequence -29, -49, -69, … is -1209.

Step-by-step explanation:

The given arithmetic sequence is -29, -49, -69, …

To find the 60th term of this sequence, we need to use the formula for the nth term of an arithmetic sequence:

a_n = a_1 + (n - 1)d

where a_n is the nth term of the sequence, a_1 is the first term of the sequence, n is the number of terms in the sequence, and d is the common difference between consecutive terms.

In this case, a_1 = -29 and d = -20 (since each term is 20 less than the previous term). We want to find a_60, so we substitute n = 60 into the formula:

a_60 = -29 + (60 - 1)(-20) = -29 + 59(-20) = -29 - 1180 = -1209

Therefore, the 60th term of the arithmetic sequence -29, -49, -69, … is -1209.
