Mathematics
1 answer:
beks73 [17]3 years ago
3 0

Answer:

(2,5) is the solution of the system

Step-by-step explanation:

x= 2, y= 5

if we substitute this values in equation y = 2x + 1

y= 2(2) + 1 = 5 (true for y and x in equation (1))

Let's check for x- y = -3

x = -3 + y = -3 + 5 = 2 ((true for y and x in equation(2) also)

Find the median and mean of the data set below: 30, 39, 24, 19, 18 Median Mean​
Eva8 [605]

Answer:  mean=26 , median=24

Step-by-step explanation:

Mean=Sum of all values/number of values

mean= 30+39+24+ 19+18/5

         = 130/5

 mean=26

Median

arrange data in order

    18,19,24,20,39

In the case of ungrouped odd-numbered data, the number that  divided data into 2 equal parts is called the median.

so median=24

URGENT!! GEOMETRY TRANSLATIONS. INCLUDE EXPLANATION IF POSSIBLE
STatiana [176]

First find the new coordinates for P and Q after the translations:

P'(2 + 3, 4 - 4) = P'(5, 0)

Q'(-3 + 3, 2 - 4) = Q'(0, -2)

Now, find the slope from this:

(0 - (-2))/(5 - 0) = 2/5

The slope has remained the same. It is important to note that after any translation, the slope will always remain the same. However, this is not always so for rotations and reflections.
