Answer:
Step-by-step explanation:
Let x represent the number of lawns mowed and y represent the number of cars washed.
1. Since the number of cars that Beth wash is no more than four times the number of lawns Mike has scheduled to mow, you have that .
2. Beth will wash at least 50 cars, then
3. Mike charges $25 each time he mows a yard, then he earns $25x for mowing x yards. Beth charges $15 for each car she washes, then she earns $15y for y cars washed. They need at least $1975, so
4. A set of constraints to model the problem is
Answer:
Dude where is the graph?
Step-by-step explanation:
Answer:
C. as t^2+t +t =t^4 + 9^2-3+3=9^2 = t^3 - 81 we are forced to -81 as we would be required to move t^3 first to the other side before -81 therefore if t is a perfect square of 4 and 9 is a perfect square too we can use. Since both terms are perfect squares, factor using the difference of squares formula,
a2−b2=(a+b)(a−b)where a=xand b=9.(x+9)(x−9)
