answer.
Answer:
x=2 and y=0 is the required result.
Step-by-step explanation:
We have been given system of equations:
5x+2y=105x+2y=10 (1)
And 3x+2y=63x+2y=6 (2)
We will use elimination method:
Multiply 1st equation by 3 and 2nd equation by 5 we get:
15x+6y=3015x+6y=30 (3)
15x+10y=3015x+10y=30 (4)
Now subtract (4) from (3) we get:
-4y=0−4y=0
y=0y=0
Now, put y=0 in (1) equation:
5x+2(0)=105x+2(0)=10
5x=105x=10
x=2x=2
Hence, x=2 and y=0
Answer:
18.75 or 18 3/4
Step-by-step explanation:
Answer:

Step-by-step explanation:
First we need to compute the side length as a function of h
So x be the side length of the right isosceles triangle, in Pythagorean formula we have



The cost for the legs is

The cost for the hypotenuse is

So the total cost in term of h is

AB=CD (given)
AB=AM+DM (M is mied point of AB&CD
CD can be writen as AM+DM)
Answer:

Step-by-step explanation:
Required
Equation of line
passes through 
In an equation of the form
; the slope is 
So, by comparison;
The slope of
is: 
From the question, we understand that the required equation is perpendicular to 
This means that its slope is:

So, we have:

The line equation is:

Where:

So, we have:
