Answer:

The last one 5x-3y=15 This is the same as y= (5/3)x -5

Step-by-step explanation:

5x-3y=15

Move 5x to the right (becoming negative)

-3y = -5x +15

Divide everything by - 3

y= (5/3)x -5

y intersect= -5 ( line crosses y coordinate at -5)

Slope = 5/3 From -5 you start counting (5 up,3 right,5 up,3 right.... OR 5 down,3 left,5 down,3 left........)

8 and 4.
To find the numbers, just divide 32 by whole numbers until you get a whole number as an answer, and try adding those to get the number you need to get.

21. Find the distance between the points. Leave your answer

asambeis [7]

Answer:

The answer is

$\sqrt{65} \: \: \: units$

Step-by-step explanation:

To find the distance between two points we use the formula

$\sqrt{ ({x1 - x2})^{2} + ( {y1 - y2})^{2} }$

where

( x1 , y1) and ( x2 , y2) are the points

From the question the points were

(-8,5), (-1.1)

Substitute the values into the above formula

That's

$\sqrt{ ({ - 8 + 1})^{2} + ({5 - 1})^{2} }$

$\sqrt{ ({ - 7})^{2} + {4}^{2} }$

$\sqrt{49 + 16}$

We have the final answer as

$\sqrt{65} \: \: units$

Hope this helps you
