picture included , please help, which of the following equations describe the line shown below (1,10) and (-3,2) *check all that

rosijanka [135]

Slope is $\text{m}=\frac{y_1-y_2}{x_1-x_2}=\cfrac{10-2}{1-(-3)}$
Then you use the equation
$\text{y=mx+b}$
Where b is the y-intercept. To find it, plug in x and y from one of the points. Say, point 1 (1,10):
$10=m(1)+b$
You know m (from above) and now you can solve for b.

Rearrange terms:
$y-b=mx$

And that will be the answer.

Make sense?

Solve the equation for a? z=mab. a)a=z+mb b)a=z-mb c)a= mb/z d)a=z/mb

Bingel [31]

Answer:

a = z/mb

Step-by-step explanation:

Given:

$\displaystyle \large{z=mab}$

To solve for a, divide both sides by the variables mb to isolate a-term.

$\displaystyle \large{\dfrac{z}{mb}=\dfrac{mab}{mb}}$

Simplify the expression and we finally have solved for a-term.

$\displaystyle \large{\dfrac{z}{mb}=a}\\\\\displaystyle \large{a=\dfrac{z}{mb}}$

Therefore, the answer to this question is a = z/mb.

Please let me know if you have any questions regarding my answer or explanation!

If x = 2y = 3 <br>find xy-y+ x × x

olga_2 [115]

Answer:

here ....x = 2 and y = 3

$= xy - y + x \times x$

$= 2 \times 3 - 3 + 2 + 2 \times 2$

$= 6 - 3 + 2 + 4$

$= 12 - 3$

$= 9$

(a) The probability that an automobile being filled with gasoline will also need an oil change is 0.35; the probability that it

cricket20 [7]

Answer:

0.714 ; 0.556 ; (A1 n A2 n A3) = 0

Step-by-step explanation:

Given that :

P(oil) = 0.35

P(filter) = 0.45

P(oil n filter) = 0.25

1)

P(filter | Oil) = P(oil n filter) / P(oil)

P(filter | Oil) = 0.25 / 0.35 = 0.714

11)

P(Oil | filter) = P(oil n filter) / P(filter)

P(Oil | filter ) = 0.25 / 0.45 = 0.556

Number of red aces = 2

Queen or king = 4 + 4 = 8

Number on card greater than 3 and less than 8 = {4,5,6,7} = 4 card ; for 4 suits = 4 * 4 = 16

Total number of cards in deck = 52

Choosing without replacement :

Hence,

A1 = 2 / 52

A2 = 8 / 51

A3 = 16 / 50

(A1 n A2 n A3) ;this means card common to all three events.

However, (A1 n A2 n A3) = 0 because ;

1.) No red ace card is greater than 3 and less than 8.

11.) An ace card can neither be a king nor a queen
