By solving 1 & 2
no solution.
He is at -18 feet because you do -28 - 5 which equals -33 after that you do -33 + 15
1/4 is one of the fractions
We have that
point A(-7,2) and point B(-1,-4)
Step 1
find the distance AB
d=√[(-4-2)²+(-1+7)²]------------> √[36+36]
d=√72
step 2
find the point M
five-sixths of the distance from AB----------> (5/6)*√72
see the attached figure
AC/AB=x/((5/6)*AB)
6/(AB)=x/((5/6)*AB)--------> 6=6x/5
x=30/6-------> x=5
CB/AB=y/((5/6)*AB)
6/AB=y/((5/6)*AB)---------> 6=6y/5
y=30/6-------> y=5
therefore
the coordinate x of point M is
A(-7,2)
Mx=-7+5=-2
the coordinate y of point M is
A(-7,2)
My=2-5=-3
the point M is (-2,-3)
You need 2 inequalities to solve this, one based on the NUMBER of printers and one based on MONEY. You will sell at least 100 printers, so your first inequality would be A+B>=100 (that's greater than or equal to). The second is based on the profit earned from each because the question in the end wants you to find how many you need to sell of each to make a profit of at least 3850. So the second inequality looks like this: 45A+35B>=3850. Solve the first inequality for A: A=100-B. Now sub this new A into the second inequality to get 45(100-B)+35B>=3850. Distribute to get 4500-45B+35B>=3850. Do the math to get that you need to sell 65 of B and 35 of A
