What equation is parallel to y= -1/4+5 and passes through (2,-3)? <br> HELPPPPP PLEASE!!!!

IrinaVladis [17]

Answer:

y = -1/4x - 5/2.

Step-by-step explanation:

I am assuming you mean y = -1/4x + 5.

This has slope of -1/4 so the required equation has the same slope ( as they are parallel).

Using the point-slope form of the equation of a line:

y - (-3) = -1/4(x - 2)

y + 3 = -1/4(x - 2)

y = -1/4x + 1/2 - 3

y = -1/4x - 5/2

Susie collected data on the favorite type of music of the students of two grades. The table below shows the relative frequencies

svp [43]

Answer:

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

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 %.

Which equation can be used to determine the distance between the origin and (-2, -4)?

sveticcg [70]

$~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-2}~,~\stackrel{y_1}{-4})\qquad \underset{origin}{(\stackrel{x_2}{0}~,~\stackrel{y_2}{0})}\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[0 - (-2)]^2 + [0 - (-4)]^2}$

How to convert 0.0001 to a power of 10 please thanks

alexandr402 [8]

Your answer is 10^(- 4).

Think about how exponents with a base 10 work. 10^1 = 10, 10^2 = 100, 10^3 = 1000. It's just add a zero to the right side as you go up.

Then think about 10^0. Anything to a zero power is 1. Only way to go is into negative exponents now. If for positive exponents on 10 we add a zero to the right side, then for negative exponents we add them to the left. Only difference is we have a decimal.

10^(- 1) = 0.1
10^(- 2) = 0.01
10^(- 3) = 0.001

And then your answer

10^(- 4) = 0.0001

Hopefully that explanation makes sense. Exponents can be rough to explain when you're not face-to-face or using some sort of live animation to talk through it. If you're still confused, I'd suggest talking to your instructor.
