Answer:
3
Step-by-step explanation:
the distance from the point of dilation to point C is 3
the distance from the point of dilation to point A is 9
9/3 = 3
hope this helps, pls mark brainliest :D
So we know that the bacteria grows 3x as much every ten minutes. From this we know that it'll be 3 mm in 20 minute. Continuing the pattern, we can figure out that in 40 minutes the bacteria will be 81 mm.
The pattern: 10min - 3 20min - 9 30min - 27 40min - 81
Answer:
y=5/3x+7/3
Step-by-step explanation:
Here are the points: (1,4) and (-2, -1)
let's first find the slope, which is with the equation m=(y2-y1)/(x2-x1) (m is the slope)
label the points:
x1=1
y1=4
x2=-2
y2=-1
now subsitute into the equation
m=(-1-4)/(-2-1)
m=-5/-3
m=5/3
the slope of the line 5/3
Here's the equation so far:
y=5/3x+b (b is a place holder)
we can substitute either one of the points into the equation so far to find b, because the line will pass through both of them>
let's use (1,4) as an example
4=5/3(1)+b
4=5/3+b
subtract 5/3 from both sides
7/3=b
Now, put it all together:
y=5/3x+7/3
Hope this helps!
Answer:
The correct answer is 2 . (1 , 3)
Step-by-step explanation:
A function is used to denote a particular relationship between variables. They can even be visualized as an input-output machine.
Every function has a domain set and a co-domain set. A function maps elements from domain to the elements of co-domain.
Here the domain can be considered as { 0 , 2 , 5 , 7}.
Here the co- domain can be considered as { 1 , 3, 8 , 2}.
For a function to be a valid function, all elements from the domain should have an image in the co- domain and every element of domain should have exactly one image in the co-domain.
Here the options 1 , 3 and 4 violate the second necessary criteria for the function to be valid.
Hence (1 , 3) is the correct answer.
Answer:
Dequan walks 5 miles per day.
Step-by-step explanation:
So solve this problem, we just need to divide 20 miles by 4 days.
20 ÷ 4 = 5
Therefore, Dequan walks 5 miles per day.
Hope this helps! :D
