Answer:
Step-by-step explanation:
Given
Represent number of DVDs with x
(at most)
Required
Represent as an inequality
If
x DVD would cost:
So, to make an order of x DVDs, Deacon will pay for
x DVDs and Handling Fee
So:
Recall that his budget is at most $75
This implies that: 
So, the relationship between his payment and budget is:
To isolate b on one side of the equation, all you have to do is subtract mx from both sides, so the answer is
y-mx =b
5x-5=-7y
3x+2y=-8
First, you need to rearrange the first equation so it is in the same format as the second one.
5x-5=-7y
Add 5 to both sides
5x-5+5=-7y+5
Add 7y to both sides
5x+7y=-7y+7y+5
So you have 5x+7y=5
Now you need to multiply that equation by 3
3(5x+7y=5)
15x+21y=15
Multiply the second equation by -5
-5(3x+2y=-8)
-15x-10y=40
Now add them together
15x+21y=15
+(-15x-10y=40)
---------------------
11y=55
y=5
Now plug y=5 into one of the original equations and solve for x.
3x+2(5)=-8
3x+10=-8
3x=-8-10
3x=-18
x=-6
To check the solution plug them both into the other equation:
5(-6)-5=-7(5)
-30-5=-35
-35=-35
It checks.
Hope that helps.
The area of the right angled triangle is 8 cm^2.
According the statement
we have to find the area of the right angled triangle with the help of the given equation.
So, For this purpose, we know that the
A right-angled triangle is a type of triangle that has one of its angles equal to 90 degrees. The other two angles sum up to 90 degrees.
From the given information:
The length of the perpendicular side (call as a) = 2cm
And
The length of the base side (call as b) = 8cm
We know that the area of the right angle triangle is :
Area = ab /2
Then
substitute the terms in it then
Area = 2*8/2
Area = 8 cm^2.
So, The area of the right angled triangle is 8 cm^2.
