Answer:

\large\boxed{\text{The slope}\ m=\dfrac{2}{3}}

Step-by-step explanation:

The slope-intercept form of a line:

y=mx+b

m - slope

b - y-intercept

We have the standard form of a line:

2x-3y=5

Convert to the slope-intercept form:

2x-3y=5          <em>subtract 2x from both sides</em>

-3y=-2x+5        <em>divide both sides by (-3)</em>

y=\dfrac{-2}{-3}x+\dfrac{5}{-3}\\\\y=\dfrac{2}{3}x=-\dfrac{5}{3}\to m=\dfrac{2}{3}

Answer:

Step-by-step explanation:

subtract 2x from both sides of the equation

-3y=-2x+5

Divide each by -3 and simplify

- 3y/-3=-2x/-3+5/-3

reduce and cancel the common numbers

move the negative over from the denominator

-(-1*y)= - 2x/-3 +5/-3

simplify

- -2x/3

multiply  2x/3 by 1

y=2x/3+5/-3

move the negative in front of fraction

y=2x/3 -5/3

slope intercept form

y=2/3 x -5/3

the slope is 2/3

So 5
then 5 times 5
then 5 times 5 times 5
so it seems that for x rounds, there will be 5^x 

A: 4 rounds so 5^4=625 photos
B. see how many times 5 goes into 78125. the answer is 7 so 7 rounds
C. 1 million=1,000,000 so try big numbers
5^10=9,765,625 too big
5^9=1,9,53,125 too big
5^8=390625 too small
the minimum is 5^9 or 9 rounds

A:4
B:7
C:9

Noah is running a portion of a marathon at a constant speed of 6 mph. Complete the table to predict how long it would take him t
ycow [4]

Answer:

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}

Step-by-step explanation:

Noah's running speed = 6 mph.

Use formula D=v\cdot t, where

D is the distance,

v is the speed,

t is the time.

If t=1 hour, then D=6\cdot 1=6 miles.

If t=\dfrac{1}{2} hour, then D=6\cdot \dfrac{1}{2}=3 miles.

If t=1\dfrac{1}{3} hours, then D=6\cdot 1\dfrac{1}{3}=6\cdot \dfrac{4}{3}=8 miles.

If t=1\dfrac{1}{2} hours, then D=6\cdot 1\dfrac{1}{2}=6\cdot \dfrac{3}{2}=9 miles.

If t=9 hours, then D=6\cdot 9=54 miles.

If t=4\dfrac{1}{2} hours, then D=6\cdot 4\dfrac{1}{2}=6\cdot \dfrac{9}{2}=27 miles.

So, the table is

\begin{array}{cc}\text{Time}&\text{Distance}\\ \\1&6\\ \\\dfrac{1}{2}&3\\ \\1\dfrac{1}{3}&8\\ \\1\dfrac{1}{2}&9\\ \\9&54\\ \\4\dfrac{1}{2}&27\end{array}
