Answer:

A. 1

B. -1

C. 5

Step-by-step explanation:

A. Using the Formula, we get u sub 2 = 9-9+1, which is just 1

B. Using the Formula, we get u sub 3 = 1-3+1, which is equal to -1

C. Using the Formula, we get u sub 4 = 1-(-3)+1, which is just 1+3+1 = 5

I’ll give you brainlest if you answer this question correctly!
slamgirl [31]

Answer:

(5,4)

Step-by-step explanation:

multiply each equation by the value that makes the coefficients of x opposite

(-1) · (4x + 6y) = (-1) · 44

4x + 2y = 28

simplify

-4x - 6y = -44

4x + 2y = 28

add the two equations together to eliminate x from the system

      -4x - 6y = -44

<u>+      4x + 2y = 28</u>

              -4y = -16

divide each term by -4

y = 4

substitute the value for y into one of the original equations, then solve for x

-4x - 6y = -44

-4x - 6(4) = -44

-4x - 24 = -44

     + 24   + 24

-4x = -20

divide by -4

x = 5

so, since x = 5 and y = 4 ....

the solution to the independent system of equations can be represented as a point.

Mackenzie ran the olympic marathon of 26 1/5 miles in a time of 5 4/5 hours. How far did she run in a 1 hour?​
padilas [110]

Answer:

Step-by-step explanation:

v=d/t (average velocity equals distance divided by time)

26.2mi/5.8h=4.5mi/h

So Mackenzie runs approximately 4.5 miles in an hour (rounded to nearest tenth of a mile)
