Answer:
<h2>-3</h2>
Step-by-step explanation:
The formula of a slope:
From the graph we have two points <em>A(-1, 2)</em> and <em>B(0, -1)</em>.
Substitute:
Answer:
empty spaces in order from left to right are 16,12,42
Step-by-step explanation:
because your adding one to the 5 so you add one to the 15 then your × by 12 bc 3×12 is 36 and × by 12 on the top so 6×12 then last one ur adding 6 because 12+6 is 18 and what ever you do to the top or bottom you do the the bottom or top
Answer:
6. (2,1) 7. (2,2)
Step-by-step explanation:
Number 6, Since it is a dilation of .5 you divide the x and y coordinate by 2 to get (2,1). X - 4/2=2, Y - 2/2=1
Number 7, Since it's rotating 90 degrees counterclockwise you switch the x and y coordinates. So from (x,y) to (y,x) and also when going counterclockwise you have to make the y coordinate becomes negative, so the counterclockwise equation is (-y,x) plug in your numbers and you get (2,2) as your 90 degree counterclockwise rotated coordinates.
3 n
- = -
4 10
cross multiply to get 4n=(3)(10)
multiply 3 and 10. 4n/4 = 30/4
n = 7.5
