Answer:
Opposite exterior angle
Step-by-step explanation:
y = -2x - 9 ----------- 1
y = 3x + 1 -------------- 2
Step 1
Substitute y from equation 1 to equation 2.
y = -2x - 9
3x + 1 = -2x - 9
Step 2
Collect like terms
3x + 2x = - 9 - 1
5x = -10
Step 3
Divide through by 5
x = -10/5
x = -2
Step 4
Substitute x in equation 2 to find y.
y = 3x + 1
y = 3(-2) + 1
y = -6 + 1
y = -5
So the solution is (-2, -5)

<span>Using
the information give, we can create two equations with two unknows as shown
below:
50U+20E=10680 and
U+E=280.
Where U represents Unlimited ride passes
and E represents Entrance-only passes. We can use the second equation to find
the value of U in relation to E. So that U is represented as U=282-E. We then
proceed to substitute E in the first equation using the value we assigned it
in relation to U so that we can have only one unknown value in the equation.
So 50U+20E=10680 becomes 50(282-E)+20E=10680. Simplifying this equation,
14100-50E+20E=10680. Putting the unknowns on one side we end up with
14100-10680=50E-20E. Solving for E, we end up with E=114. U can also be
calculated by substituting the already known value of E in the simpler
equation U=280-114. This means that the value of U is 168. So the number of
unlimited passes that were sold is 168</span></span>
Answer:
73 x 51 x 1/2(basically just dividing by 2) = 1861.5
1861.5 x 86(width) = 160,089 86 yd^3 is your answer.
