Slope = (y2 - y1)/(x2 - x1) = (10 - 70)/(5 - (-15)) = -60/(5 + 15) = -60/20 = -3

Find the distance between the two points in simplest radical form.<br> (-1,9) and (4, -3)

jolli1 [7]

Answer:

GIVEN BY POINTS :-

( -1, 9) , ( 4 , -3)

Here ,

$\bullet \: \: x _{1} = - 1 \\ \bullet \: \: x _{2} = 4 \\ \bullet \: \: y _{1} = 9 \\ \bullet \: \: y _{2} = - 3 \\$

Using Distance formula :

$= > \sf d = \sqrt{( {x _{2} - x _{1}) }^{2} + {( {y _{2} - y _{1}) }^{2} } } \\ \\ = > \sf d = \sqrt{ ({ 4 + 1)}^{2} + { ( - 3 - 9)}^{2} } \\ \\ = > \sf d = \sqrt{ {5}^{2} + {( - 12)}^{2} } \\ \\ = > \sf d = \sqrt{25 + 144} \\ \\ = > \sf d = \sqrt{169} \\ \\ = > \boxed{ \sf{ d = 13\:units }}\\$

The probability of event X is 30%. The probability of event Y is 40%. If events X and Y are mutually exclusive, what is the prob

Soloha48 [4]

The probability of event X or Y is P = 0.7, or, in percentage form, the probability is 70%.

<h3>How the get the probability of event X or Y?</h3>

First, two events are mutually exclusive if these events can't happen at the same time.

This means that if happens X, with a 30% of probability, then Y can't happen.

If happens Y, with a 40% of probability, then X can't happen.

Then the probability of X or Y (the probability that one of these two events happens, not both) is just the addition of the two individual probabilities.

Then we have:

P(X or Y) = 0.3 + 0.4 = 0.7

Or, in percent form, we get:

P(X or Y) = 70%

The probability of event X or Y is just 70%.

Jay wrote an equation to determine sales tax on an item he wanted to buy. The equation was Y equals 0.0 9X, where Y represents t

mixas84 [53]

Step-by-step explanation:

Given the equation:

y = 0.09x where:

x: represents the cost of the item before tax is added.
y: represents the amount of sales

=> On a coordinate plane, the x-axis is labeled Cost of Item (in dollars) and the y-axis is labeled sales tax (in dollars)

We create a table of values

x y

0 0

10 0.9

=> the line go through two points (0, 0) and (10, 0.9)

Hence tow dwaw a graph, we just connect two points together.

Please have a look at the attached photo.
