Answer:
average = 52, 100 on fourth test
Step-by-step explanation:
average = 75 + 74 + 71 = 156 / 3 = 52
average = 52
b grade = 75 + 74 + 71 + 100 = 320 / 4 = 80
to get a b grade she must get 100 on her fourth test
Y = mx + b; b = 6
<span>1 = 4m + 6; m = -5/4 </span>
<span>-5/4 = (1 + 2k) / (4 - k - 3) = (2k + 1) / (1 - k) </span>
<span>-5(1 - k) = 4(2k + 1) </span>
<span>5k - 5 = 8k + 4 </span>
<span>-3k = 9 </span>
<span>k = -3</span>
