Answer:

$\star\mathtt{Ans.\:\#1:\:Slope:-8}$

$\star\mathtt{Ans.\:\#2:\:y\:intercept:\:1}$

Step-by-step explanation:

Hi student, let me help you out.

<u></u>

First note that the equation we are working with is in slope intercept form. Do you remember the slope intercept form equation? It's $\mathtt{y=mx+b}$ .

In the slope intercept form equation, "m" denotes "slope" and "b" denotes "y intercept".

Looking back at our equation, let's work out the slope & y intercept.

Let's put these two equations together:

$\mathtt{y=mx+b}$

$\mathtt{y=-8x+1}$

See what I mean? The y intercept of this equation is 1 and the slope is -8.

Hope this helped you out! Ask in comments if any queries arise.

Step-by-step explanation:

Your table was hard to decipher, so I have recreated it here.

$\begin{array}{c|cccc}&\text{Pop}&\text{Classical}&\text{Heavy Metal}&\text{Total}\\\text{Grade 8}&0.50&0.10&0.40&1.00\\\text{Grade 9}&0.53&0.20&0.27&1.00\\\text{Total}&0.36&0.32&0.32&1.00\\\end{array}$

(a) In Grade 9, 53 students liked pop music.

FALSE. 53 % of the students liked pop music. We don't know how many students there were.

(b) In Grade 8, 60% of students liked heavy metal.

FALSE. 40 % of students liked heavy metal.

(c) In Grade 8, 10 students liked classical music.

FALSE. We don't know how many students there were.

(d) In Grade 9, 20% of students liked classical music.

TRUE. 0.20 means 20/100 or 20 %.

How do you solve for percent increase and percent decrease?

murzikaleks [220]

for increase:

Increase = New Number - Original Number

Then divide the increase by the original number and multiply the answer by 100

For decrease:

Decrease = Original Number - New Number

Then divide the decrease by the original number and multiply the answer by 100

Which of the following points lies on the circle whose center is at the origin and whose radius is 10?

Naddik [55]

Since the standard form of the circle is:

(x-h)^2+(y-k)^2=r^2, and (h,k)=(0,0) and r=10 so we have:

x^2+y^2=100 Looking at the points you have:

(√10, 0) does not work as (√10)^2+0^2=10+0=10

(0, 2√5) does not work as 0^2+(2√5)^2=0+20=20

(5√2, 5√2) works as (5√2)^2+(5√2)^2=50+50=100
