Answer:
The demabd function is:
Step-by-step explanation:
The demand follow the linear equation 
1. When p=$2.00 and q=9000, the equation is:
2. Whe p=$4.00 and q=0, the equation is:
3. Solve equation (1) for b:
4. Replace the value of b in equation (2)
The value of m is 4500
5. Calculate b, replacing m:
The value of b is 18000
Answer: 17.5
Step-by-step explanation:
Answer:
x= 1
y= -1
Hope this helps!
Step-by-step explanation:
1 Substitute y=3x−4 into y=x-2
3x-4=x-2
2 Solve for x in 3x-4=x-2
x=1
3 Substitute x=1 into y=3x-4
y=-1
4 Therefore,
x=1
y=-1
Answer:
So, this triangle PQR can be broken into two right triangles, PNQ and PNR, with legs PQ = 39, PN =15, and QN = ? and PR = 17, PN = 15, and NR =? respectively.
Let's solve for what is easier first:
Since we know that 5-15-17 is a Pythagorean triplet, we can infer that NR is 5....like I said earlier, it is a right triangle, so this guess holds true.
Here comes the interesting part:
Now, we have one part of QR, which is QN.
The other part can be solved by using the Pythagorean theorem.
It is (39^2-15^2)^(1/2)..which gives you 36, the square root of 1296, which happens to be the difference between the squares of 15 and 39.
SO, QR = QN + NR
5+36 = 41
QR = 41.

Answer:
x=2
Step-by-step explanation:
Since rectangles have 90* angles at each corner, we can say the two equations in the corner equal to 90*
so,
13x+34+10x+10=90
23x+44=90
23x=46
x=2
