Answer:
Rasheed bought 9 packages of chocolates bar.
Step-by-step explanation:
Let C be the number of packages of chocolate bars.
Let T be the number of packages of toffee bars.
Rasheed handed out 2/3 of 2C of the chocolate bars and 3/5 of 2T of the toffee bars.
(1) Rasheed bought 1 fewer package of chocolate bars than toffee bars.
Equation becomes:
.....(1)
(2) Rasheed handed out the same number of each kind of candy bar .
Equation becomes:
=> 
=> 
=> 
Taking out 2 common, we get
......(2)
Substituting in (2)
=> 
=> 
T = 10
As
C = 9
Therefore, Rasheed bought 9 packages of chocolates bar.
Answer: -1410
Step-by-step explanation:
Let's start by subbing in -4 for x
Now we can solve
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
Where:
m: Is the slope
b: Is the cut-off point with the y axis
According to the data of the statement we have to:
Then, the equation is of the form:
We substitute the point
and find "b":
Finally, the equation is:
To graph we place the points 
and
on the coordinate axis and join the points by a line.
ANswer:
The graphic is attached.
For a line in the form:
In this case, for the line 2x + 10y = 20 with a=2 and b=10 the slope is:
Now, two lines are perpendiculars if the slopes satisfy the following equation:
So, for the line we want the slope is:
Finally, the line pass througth the point (2, 3) with slope m=5, so the equation is:
The equation of the line is y = 5x - 7
Angle a is 22.62 degrees
and
angle b is 67.38 degrees
