Answer:

Maleka's method

Step-by-step explanation:

Maleka's method is unbiased because He or She has a list of all of the high school students at that school and chooses the tenth one. It can't be Tony's either because it is just his class which is biased.

Do i divide The 3? 3y=0

adoni [48]

Answer:You do inverse operations to get the y alone so for the -3-3y=0 you would to +3 to the 0 so the equation is now -3y=3 now from here you do 3 divide by -3 which is -1 so no your answer is y=-1

3.1 Find the equation of the line passing through (4, 5) and parallel to the line 3x – 2y = 4.

<em>Find the equation of the line passing through (4, 5) and parallel to </em>

<em />

<em> </em> $\rule{50}{1}\large\blue\textsf{\textbf{\underline{Answer and how to solve:-}}}\rule{50}{1}$

First of all, We need to convert this equation from standard form (ax+by=c) into slope-intercept form (y=mx+b).

$\rightarrow$ First, add 2y on both sides:-

$\Large\textsf{3x+2y=4}$

$\rightarrow$ Now, subtract 3x on both sides:-

$\Large\textsf{2y=-3x+4}$

$\rightarrow$ Divide by 2 on both sides

$\Large\text{$y=-\displaystyle\frac{3}{2}x +2$}$

$\rule{300}{3}$

Now, let's find the equation of the line that's parallel to the given line.

Remember, if lines are parallel to each other, then their slope's the same.

So the slope of the line that's parallel to the line whose equation we just found, is

$\Large\text{$-\displaystyle\frac{3}{2}$}$

Now let's write the equation in point-slope form:-

$\hookrightarrow\sf{y-y_1=m(x-x_1)}$

Replace numbers with letters, as follows:-

$\sf{y-5=-\displaystyle\frac{3}{2} (x-4)}$

The equation above is the equation in point-slope form.

Incase you need it converted to slope intercept form, refer to the steps below ~

Multiply -3/2 times x and -4:-

$\hookrightarrow\sf{y-5=-\displaystyle\frac{3}{2} x-6}$

Now, Add 5 on both sides:-

$\hookrightarrow\sf{y=\displaystyle\frac{3}{2} x+1}$

Amanda is making some strawberry preserves. She has three sizes of canning jars. Small pint size, medium quart size, and large h

pashok25 [27]

The answer is 15.

S - small jar
M - medium jar
L - large jar

In all Amanda has 22 jars: S + M + L = 22
She has three time as many small jars as large: S = 3L
She has three fewer mediums than large: M = L -3

Now, we can use the method of substitution:
S = 3L
M = L - 3
_______________
S + M + L = 22
3L + L - 3 + L = 22
3L + L + L = 22 + 3
5L = 25
L = 25 ÷ 5 = 5

Since S = 3L, then:
S = 3 · 5 = 15

Amanda has 15 small jars.
