24.65 also next time just use a calculator
Let
x------------> <span>the flags length
</span>y------------> the flags <span>width
P----------> perimeter
we know that
p=2x+2y------> 2x+2y=560----------> equation 1
and
x=y+40-------------> equation 2
</span> substitute 2 in 1<span>
2*(y+40)+2y=560-----------> 2y+80+2y=560--------> 4y=480------> y=120
x=y+40-------> 120+40----------> x=160
the answer is
</span>
the flags length is 160 ftthe flags width is 120 ft
Part 2) Write three
situation to which you could apply the resulting system of equations 1) It can be used when considering the relationship between the price of a product and the quantities of the product that people want to buy at a certain price.
2) It can be used to determine the speed, distance and time duration when traveling by car, and you want to know the values of the unknown variables in your trips.
3) It can be used to determine the most convenient loan option to buy a car or a house when considering the duration of the loan.
Answer:
under the condition of f(x)=x composite function is an identity one
X raised to the power of two" or equivalently "x squared" (which is x mulitplied by itself). In fact, if we multiply the variable x by itself a number of times (say n - times) we get: xn. The number represented here as x is called the base, and n is called the power or exponent.
You could just subtract the numbers from the line. It's simple.
