Question
Consider this system of equations. Which shows the second equation written in slope-intercept form?
A.
B.
C.
D.
Answer:
B.
Step-by-step explanation:
Given
Equation 1:
Equation 2:
Required:
Equivalent of equation 2
To get an equivalent of equation 2 (in slope intercept form), first we have to simplify equation 2
Open the bracket
Simplify fraction
Divide through by 2
Re-arrange
The next step is to compare each of option A through D with
A.
is not equal to
We check the next available option
B.
is equal to
This option is equivalent to the second equation in slope-intercept form.
We check further if there are more equivalent options
C.
Convert fraction to decimal
This is not equal to
D.
Convert fraction to decimal
This is not equal to
Hence, the only equation that is equivalent to the second equation written in slope intercept form is Option B
Answer:
66.67 %
Step-by-step explanation:
As we can see from the figure
We are given a bar graph in which bars represent the number of reserved campsites at a camp ground for one week from Monday to Sunday.
First of all
Lets the count the total number of reservations made by campsites during the week.
Total Number of campsite reservations = 5+3+4+7+26+30+9
Total Number of campsite reservations =84
Now
we have to calculate what percent of reservations were made for friday or saturday.
% of reservations made on friday or saturday =
% of reservations made on friday or saturday =
% of reservations made on friday or saturday =
% of reservations made on friday or saturday = 66.67 %
So in total 66.67 % reservations are on friday and saturday.
