Answer: +9

Step-by-step explanation: When an integer is written with vertical bars on either side, it means that we take the absolute value of that integer.

The absolute value of an integer is its

distance from zero on a number line.

|9| is +9 because it's 9 units from zero on the number line.

Consider the quadratic function f(x)=−x^2+4x+12
777dan777 [17]
<h2>Answer:</h2>
  • The smallest x-intercept is x= -2
  • The largest x-intercept is x=  6
  • The y-intercept is y= 12
<h2>Step-by-step explanation:</h2>

We are given a function as follows:

y=f(x)=-x^2+4x+12

The x-intercept of a function is the value of x where the function is equal to 0.

i.e.

y=f(x)=0

-x^2+4x+12=0

i.e.

x^2-4x-12=0\\\\x^2-6x+2x-12=0

( We used the method of splitting the middle term)

x(x-6)+2(x-6)=0\\\\(x+2)(x-6)=0

i.e.

x=-2\ and\ x=6

Hence, the smallest x-intercept is: x= -2

and the largest x-intercept is: x=6

The y-intercept is the value of y where x=0

i.e. we have:

y=-0^2+4\times 0+12\\\\y=12

A university's leadership council is made up of 10 members: 3 are students, 3 are teachers, and 4 are deans. A newspaper reporte
Vlad [161]

Answer:

1/15

Step-by-step explanation:

First you must figure out your total outcomes, int the problem it said ten. Than take the number of students and put the number of students over the number of outcomes. This will tell you the probability of drawing one student. Next you must subtract 1 student and one member from your original equation. This is because you have assumed that the first drawing had a favorable outcome. So that leaves you with 2/9. Next you must multiply both the first fraction (3/10) and the second fraction (2/9) to come up with the total probability of the event occurring.

Hope that helped.
