How many solutions are there for the equation below? -46 = 3x + 7x - a. infinitely many b. 1 c. 2

There is only 1 solution.

Combine the "xs" on the right.

-46 = 7x + 3x

10x = - 46

10x = - 46   Divide by 10

x = - 4.6  

Note: No other answer is possible.

y=mx+b

step-by-step explanation:

m slope, b y-intercept

(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
