Answer:
1.3223 is the answer for y
Answer:
{
}
Step-by-step explanation:
The given system of equations is;
and
We rewrite the equations in the standard form to get:
We now substitute equation (3) into equation (4) to get:
Group similar terms:
Divide both sides by 2
This implies that:
Therefore the solution set is:
{}
The answer is 6 3/22
i multiplied the numerator and denominator by 2 of the second equation and subtracted like tht.
Answer:
Not a solution.
Step-by-step explanation:
y = 5x + 9
-3 = 5(-2) + 9
-3 = -10 + 9
-3 ≠ -1
The point given is not on the line. It is NOT a solution to the equation.
Hope this helps.
We will use trigonometry:
tan 45° = 1500 / x
1 = 1500 / x
x = 1500 ft
tan 42° = 1500 / y
0.9 = 1500 / y
y = 1500 : 0.9
y = 1666.67 ft
L = y - x ( where L is the length of the runway )
L = 1666.67 - 1500 = 166.67 ft.
