What are the means of the following proportion 17/51=28/84?

The two middle numbers are the means and outer ones are extremes.

So, in 50 and 28 are means and 17 and 84 are extremes.

Suppose we have two ratios a:b and c:d which are in proportion.

So it is written as : so 'a' and 'd' are extremes and 'b' and 'c' are means.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )
