Can someone help me please

 D.)  y = 2x + 1

Step-by-step explanation:

in slope-intercept form, y = mx + b, m is the slope, Rise/Run

The difference in y-values, rise,  increases by 2  for every increase of 1 in x-values, the run.

2/1 is the slope

m = 2

b is the y-intercept

To calculate b, substitute any pair of y and x values from the chart, and the value 2 for m:

9 = 4(2) + b

9 = 8 + b

1 = b  

Rewrite the equation with the values calculated for m and b. Keep y and x

y = 2x + 1

  21.3

step-by-step explanation:

multiplying the given equation by c/sin(25°), we get

  c = 9/sin(25°) ≈ 21.2958 ≈ 21.3

we assume "c" is the length of ab, the side opposite angle c in triangle abc.

60.9774

step-by-step explanation:

because when you add 47.6 plus 7.32 equals 54.92

and when you add .0574 + 6= 6.0574

and when you add 54.92 and 6.0574 you get the answer of 60.9774.
