1 and half hour
= 60 minutes+ 30 minutes
= 90 minutes
Now,
Uzanne need 15 minutes to do 10 problems
Uzanne need 1 minute to complete 10/15 problems
Uzanne need 90 minutes to do
= (10/15)*90
=(2/3)*90
=2*30
=60 problems
Answer:
- 1, and - 1
the answer would be -2
Step-by-step explanation:
any number of the zero power is one.
Answer:
Pat a) The graph in the attached figure
Part b) 
The slope is 
The y-coordinate of the y-intercept is 
Step-by-step explanation:
Part a) Which line represents the linear equation
?
To graph the linear equation find the intercepts
we know that
The y-intercept is the value of y when the value of x is equal to zero
so
For x=0



The y-intercept is the point 
The x-intercept is the value of x when the value of y is equal to zero
so
For y=0



The x-intercept is the point 
Plot the intercepts to graph the linear equation
see the attached figure
Part b) Rewritten in slope-intercept form
we know that
The equation of the line into slope intercept form is equal to

where
m is the slope
b is the y-coordinate of the y-intercept
we have

convert to slope intercept form
isolate the variable y


The slope is 
The y-coordinate of the y-intercept is 
It seems you double the amount each day. keep doing that until you get to 15
