Answer:
x=6
y=13
Step-by-step explanation:
The statement says that:
Been y the smaller and x the larger. The other equation that we have is the summation of the two numbers. Then we have 2 equations and 2 unknowns
Solving the equations the answers is x=13 and y=6.
The answer is <span>252.5 ft
</span><span>y = –0.004x</span>²<span> + x + 2.5
Let's take y = 0 and we'll get the quadratic equation:
</span>–0.004x² + x + 2.5 = 0
The general formula for quadratic equation is:
ax² + bx + c = 0
a = -0.004
b = 1
c = 2.5
Since distance cannot be negative (x1), the correct answer is x2 = 252.5 ft
