How many chairs are there because you need an amount to know how many ways are you gonna split up the paint
Answer:
Yes, if you keep all of this in mind... This all came from my lesson during class btw.
Step-by-step explanation:
Each shows two lines that make up a system of equations. If the graphs of the equations intersect, then there is one solution that is true for both equations. If the graphs of the equations do not intersect. Almost any situation where there is an unknown quantity can be represented by a linear equation, like figuring out income over time, calculating mileage rates, or predicting profit. Many people use linear equations every day, even if they do the calculations in their head without drawing a line graph. When both equations have the same slope, but not the same y-intercept, they'll be parallel to each other and no intersections means no solutions. When both equations have different slopes than regardless of the y-intercept they'll intersect for certain, therefore it has exactly one solution. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Answer:
Step-by-step explanation:
First thing we need to do is to reconcile that r to the negative power. You do that by following the rules for exponents. If
then the rule is to subtract the lower exponent from the upper:

Doing that with our base of r:
is
which is 
So it looks like what we have now is:

NOW we will follow the rules for multiplying like bases with exponents. The rule for that is if you have like bases and you are multiplying those like bases, you add the exponents. So I'm going to kind of break up that problem and put the like bases together:

Working on the left side, p to the 3rd times p to the 4 gives you p to the 7th, which is what we have on the right. The r to the 7 is also the same on the left and the right. Working on the q's now, if we have q to the 2nd and we are looking for n, then
so 2 + n = 5 and n = 3
