Answer:

Step-by-step explanation:

The median, is just the middle number in a set of numbers.

In this case, our set is: 17, 8, 15, 21, 12.

However, the set must be in increasing order, so the set becomes: 8, 12, 15, 17, 21.

This gives us the median, which is the middle number, to be: 15.

Let me know if this helps!

Currently, the sum of the ages of Yumi, Rana and Victoria is 42 years. Four years ago, the sum of the ages of Rana and Victoria

Setler [38]

Y + R + V = 42
but 4 YEARS AGO : (R-4) +(V-4) = Y

Replace Y in the 1st equation by: (R-4) +(V-4)

(R-4) +(V-4) + R + V = 42

2R - 2V - 8 = 42; 2R -2V = 50, or R+V=25
IF R+V =25 AND Y + R +V = 42, then Y + 25 = 42 and Y =17

Answer:

So the vaule of y is 7, 10 & 13

Step-by-step explanation:

Given that y = 3x+1 . So we can just substitute x-value into the equation :

Let x=2,

y = 3(2)+1

= 7

Let x=3,

y = 3(3)+1

= 10

Let x=4,

y = 3(4)+1

= 13

Answer: $\boxed{y=\frac{4}{5}x-2}$

Step-by-step explanation:

Perpendicular lines have slopes that are negative reciprocals, so as the slope of the given line is -5/4, the slope of the perpendicular line is 4/5.

Substituting into point-slope form,

$y-6=\frac{4}{5}(x-10)\\\\y-6=\frac{4}{5}x-8\\\\\boxed{y=\frac{4}{5}x-2}$

Which inequality has –12 in its solution set? A B C D

Feliz [49]

Answer:

Step-by-step explanation:

solve each inequality:

A : x+6<8 , x<-8-6 , x<-14

B: x+4≥-6 , x≥-10

C: x-3>-10 , x>-7

D:x≤-9

since -12 is on the left side of the number line then x≤ -9 would be the solution
