Answer:

It is B

Step-by-step explanation:

To solve this, you must use factoring:

You must find two numbers that multiply to -6, and add up to 5(y).

$y^{2} +5y-6=0$ turns into...

$(y+6)(y-1)=0$ because 6 × -1 = -6, and 6-1 = 5

after that, find the roots by solving for the x in each of the parentheses

so, $x=-6$ and $x=1$

What is the value represented by the letter D on the box plot of data?

anyanavicka [17]

Hello!

The letter D is in the place for the upper quartile

To find this you have to find the median of the data

List the numbers from least to greatest

12, 18, 34, 55, 59, 68, 80, 80

The medians are 55 and 59

To get the median we take the average of these numbers

55 + 59 = 114

114 / 2 = 57

The median is 57

To find the upper quartile you find the median of the numbers higher than 57

List the numbers that are higher than 57 in the data

59, 68, 80, 80

Take the average of 68 and 80

68 + 80 = 148

148/2 = 74

The answer is 74

Hope this helps!

the equation y=0.5x represents the distance henry hikes, in miles, over time, in hours. the graph represents the rate that clark

zheka24 [161]

I think there's supposed to be a picture here. Anyway, you can find out by finding the slope of the line on the graph and comparing it to .5 which is Henry's slope. If the graphed slope is larger than .5 then Clark hikes faster, if it is less than .5, Henry hikes faster.

Hope this helps :)

The president of a certain University receives a salary that is three times the salary of one of the department heads the total

Furkat [3]

Answer:

$142500

Step-by-step explanation:

We are given that the resident of a certain University receives a salary that is three times the salary of one of the department heads.

Assuming $x$ to be the salary of the department head, if the total of the two salaries is $190000, we are to find the salary of the president of the University.

We can write an equation in terms of $x$ :

$3x+x=190000$

$4x=190000$

$x=47500$

Salary of the president of the University = $3(47500)$ = $142500
