Answer:
The number of drinks that Sarah bought was 2 and the number of candies that Sarah bought was 6
Step-by-step explanation:
Let
x ----> the number of drinks that Sarah bought.
y ----> the number of candies that Sarah bought.
we know that
she bought $35.50 worth of drinks and candies
so
-----> equation A
She bought 3 times as many candies as drinks.
so
-----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (2,6)
see the attached figure
therefore
The number of drinks that Sarah bought was 2 and the number of candies that Sarah bought was 6
Answer:
1. $0.24
2. 89.2 miles
Step-by-step explanation:
To get the unit price, divide the total price by the amount that was purchased.
1. 3.12/13 = $0.24
For the second one, get the distance traveled per hour first then multiply by 8.
22.3 / 2 = 11.15
11.15 x 8 = 89.2
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have the following points:
Substituting the values:
Thus, the line is of the form:
We substitute one of the points and find "b":
Finally we have to:
Answer:
The equation es
Answer:
Step-by-step explanation:
logx
<=> logx + 2logy = a (1)
log
y=b <=> 3logx + 6logy =b (2)
(1),(2)=> logx= 
logy= 3a-b
=> log
=logy-logx=3a-b -( ) = 
log
= 
(logx+logy)=........ OK
Answer:
B. slope: 3/2, y-intercept: 5
Step-by-step explanation:
Rewrite in slope-intercept form. The slope-intercept form is y=mx+b, where m is the slope and b is the y-intercept.
