Answer:
A.
Step-by-step explanation:
The x-intercepts are the points where the x value is zero. In this case, to find the "zeros" of the function, set each factor to zero. x-5 -> x=5. x-6 -> x=6. x+4 -> x=-4.
The wire, the pole and the segment joining the leg of the pole to the wire in the ground form a right triangle whose hypotenuse is the wire, and the side opposite to the angle 36° is the pole.
By right triangle trigonometry, sin36°=(opposite side)/(hypotenuse.)
Substituting, we have 0.588=(opposite side)/220, thus the length of the opposite side, which represents the length of the pole, is
0.588*220 ft=129.3 ft

Answer:
A sandwich costs $7.5
Step-by-step explanation:
Given
Represent chips with c and sandwiches with c
From the question, we understand that 5 sandwiches were ordered.
Hence, the question of the system is:
Substitute values for Total and c
Collect Like Terms
Divide both sides by 5
