Answer: 6
Step-by-step explanation:
Answer:
The answer is undefined.
Step-by-step explanation:
The square root of a negative number does not exist in the set of real numbers which makes this undefined.
Answer:
, graph is there for reference.
Step-by-step explanation:
Given,
is the number of math problem Lucy solved.
is the number of pages she read.
She can do each math problem in 
minutes, therefore she can solve number of questions into 
minutes.
She can read each page in 
minutes, therefore she can read pages in 2.5y minutes.
As per given detail,
equation 1.
And,
It is given that number of math problems Lucy solved is 3 times the number of pages she read.
equation 2.
We need to find and intercept of each of the equation to graph them.
For 
put y=0
We will get 
Thus the point is 
Let us find 
by assuming 
we get 
Thus the point is 
Join these two points.
Similarly considering the other equation
Here x-intercept would be at 
We will get
Thus the point is 
Let us assume on more point, say 
, we get 
Thus the point is 
Join these two points.
We will get a point of intersection at 
Thus 
and 
Point-slope form is y-y1=m(x-x1)
m=1
y1=11
x1=-2
y-11=1(x-(-2)
There is a few ways to do this but I will do it the way that will be shown. You know that you must split the clothing into 4 pieces because 1+3=4
So divide 48 by 4 which is 12. Now multiply 12 by each ration.
12×1=12
12×3=36
12+36=48 which means its right
So the ratio is 12:36
