18x-16y=5
Subtract 18x from each side
-16y=-18x+5
Divide by -16
y=18/16x-5/16

Answer:

\large\boxed{y=\dfrac{9}{8}x-\dfrac{5}{16}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the equation of a line in the standard form (Ax + By = C).

Convert it to the slope-intercept form:

18x-16y=5          <em>subtract 18x from both sides</em>

[tex[18x-18x-16y=-18x+5[/tex]

-16y=-18x+5          <em>divide both sides by (-16)</em>

\dfrac{-16y}{-16}=\dfrac{-18x}{-16}+\dfrac{5}{-16}\\\\y=\dfrac{18:2}{16:2}x-\dfrac{5}{16}\\\\y=\dfrac{9}{8}x-\dfrac{5}{16}

you can make a triangle in the corner with legs length s/2 and the angles are 45 degrees. in a 45 45 90 triangle, the legs are h/sqrt(2) where h is the hypotenuse. this means that s/2=9/2 sqrt(2), s=9 sqrt(2)

and s^2=162

A box contains 9 green marbles and 17 white marbles. If the first marble chosen was a white marble, what is the probability of c
pshichka [43]

Answer:

16/25

Step-by-step explanation:

Given

Number  of green marbles = 9

Number of White marbles = 17

Total number of marbles = 26

Probability of picking a white marble = 17/26

When a white marble is picked without replacement,

Probability of picking another white marble after first picking a white marble

= 16/25

= 0.64

This is because the total number of marbles would have reduced from 26 to 25 and the number of white marbles from 17 to 16.
