Find the equation in slope/intercept form that is perpendicular to 2x - 3y = 4 and passing through (-1/7, 4).​
MA_775_DIABLO [31]

Answer:

y = -1½x + 3 11⁄14

Step-by-step explanation:

First convert from <em>Standard Form</em> to <em>Slope-Intercept Form</em>:

2x - 3y = 4

-2x - 2x

____________

-3y = -2x + 4

___ _______

-3 -3

y = ⅔x - 1⅓ >> Slope-Intercept Form

↑

slope

Now, Perpendicular Lines have OPPOSITE MULTIPLICATIVE INVERSE <em>Rate</em><em> </em><em>of</em><em> </em><em>Changes</em><em> </em>[<em>Slopes</em>], so since the slope is ⅔, the opposite multiplicative inverse of that would be -1½, or -3⁄2. Anyway, do the following:

4 = -1½[-⅐] + b

3⁄14

-3⁄14 - 3⁄14

_______________

3 11⁄14 = b

y = -1½x + 3 11⁄14 >> New equation

I am joyous to assist you anytime.

babymother [125]

Answer with explanation:

1.Mean of a Data set

   =\frac{\text{Sum of all the observation}}{\text{total number of observation}}

=\frac{10+9+11+8+10+12+2+7+8+0+12+10+8+11+3+12+6+7+4+3}{20}\\\\=\frac{153}{20}\\\\=7.65

2. Range = Maximum value in two conferences - Minimum value in two conference

= 12 - 0

=12

The mean number of wins for teams from the two conferences is 7.65.

The range in wins is  12.

Use distributing property : (-11) x (-15) + (-11) x (-25) plzz answer fast
Semmy [17]
The answer is 440.
What I do is just take the -11 and -15 out of the parentheses so it is -11*-15 and the answer is 165. Then, you take -11 and -25 out of the parentheses and find the answer.
Add them together.
Hope that helped :)
