If y varies directly as x, and y is 16 when x is 4, when y= 24 what is the value of x?

sergejj [24]

Answer:

x = 6 possibly

Step-by-step explanation:

I am just an algebra student, but if I am correct I would appreciate a crown.

16/4 is 4, so i assumed that was the geometric pattern, so i divided 24 by 4 and got 6.

Hoped this helped.

You are competing in a race. The table shows the times from last year's race you want your time to be last year's median time wi

Answer:

$27\leq x \leq37$

Step-by-step explanation:

Let's arrange the numbers from least to greatest:

20, 25, 27, 28, 31, 32, 32, 38, 40, 40, 42, 48

The median is the "middle" number when arranged from least to greatest.

There are 12 numbers, so the middle number would be "average" of 6th and 7th terms.

6th term = 32

7th term = 32

Average = (32+32)/2 = 32

Hence, median = 32

Absolute deviation of 5 minutes means 5 minutes less or greater than the median, 32.

So, 32 - 5 = 27 & 32 + 5 = 37

Hence $27\leq x \leq37$

Write the equation in slope-intercept form. Then find the slope and y-intercept of the line.

alisha [4.7K]

Learn this...it helps

HOY -- horizontal line, 0 slope, represented by y = a number
VUX -- vertical line, undefined slope, represented by x = a number.

so ur equation y = -1....this is a horizontal line with a 0 slope
In slope intercept form it is : y = 0x - 1 <==....ur slope is 0 and ur y int is -1
