Answer:
A: -6.5
Step-by-step explanation:
Take two points that we already know are on the line and find the slope
I used:
(4, -10) and (7, -30)
X1 (first x coordinate): 4
Y1 (first y coordinate): -10
X2 (second x coordinate): 7
Y2 (second y coordinate): 30
These appear to be exactly on the graph at a certain point along the line. We can't choose a coordinate pair that isn't on the line at an exact point.
Use (Y2-Y1)/(X2-X1)
(-30-(-10))/(7-4) = (-30 + 10)/3 = -20/3 = approximately -6.67.
The closest answer to that is A.
There are 7 numbers.
Each number can be paired with the remaining 6 numbers.
7 x 6 = 42 different two digit numbers can be made.
Answer:
t=d/s
Step-by-step explanation:
search up distance speed time triangle (like the one attached) and memorize it. When u need to use it just draw it on a piece of paper and cover ur intended target. For example, if u want to find the time formula, cover the time section and you got the time formula, D/S. It helps for beginners.
Answer:
If the number of blue tiles in the bag is 180, then the probability of randomly drawing a red tile equal to 1/10.
Step-by-step explanation:
Total number of red tiles in a bag = 20
Let us assume the number of blue tiles in a bag = p
So, the total number of tiles in a bag = Red Tiles + Blue tiles
= 20 + p
Now, let us find the probability of drawing a red tile:

But, here the probability of drawing a red tile = 1/10

or, p = 180
Hence, if the number of blue tiles in the bag = 180, then the P Picking out a red tile ) is 1/10.
Answer:
Yes
Step-by-step explanation:
Plug in 4 for x, 5 for y. if it equals, then its a point
5 = -2(4) + 13
5 = -8 + 13
5 = 5
it equals so (4,5) is a point
