8 0

Answer:

80

Step-by-step explanation:

The sum of the 4 grades equals 4 times the average

94 + 78 + 83 + T = 4 * 83.75

94 + 78 + 83 + T = 335

255 + T = 335

Subtract 255 from both sides

T = 80

Answer:

Tyler got 80%.

Step-by-step explanation:

Represent Tyler's average by t.

Then .94 + .78 + .83 + t

         -------------------------- = 83.75%

                         4

Multiplying both sides by 4, we get  2.55 + t = 3.35

                                                                       

so that t = 3.35 - 2.55 = 0.80

Tyler got 80%.

Identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 1).
kari74 [83]
To get your answer, you will need to find the perpendicular slope for -1/3x which is just the opposite therefore it will be 3x. Your slope is 3x as perpendicular so use this slope to do point slope. Y-1=3(x-2). Distribute y-1=3x-6. Add 1 to both sides. (-1+1) (-6+1)=-5. So your equation in slope intercept form is y=3x-5. Going through the two points.

Hope this helps!
