A graph has quantity on the x-axis and price on the y-axis. The supply line goes through (60, 65), (75, 70), (100, 95). The demand line goes through (60, 100), (75, 70), and (80, 60). Using the above supply/demand graph, what is the price at the point of equilibrium? a. 100 b. 75 c. 70 d. 55 Please select the best answer from the choices provided A B C D

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is (-4,-4)

hope this ! : d
