Answer:
y = 3x
Step-by-step explanation:
Given line slope = m = -1/3
perpendicular line slope = - 1/m = 3
Point slope form through point 1, - 3
(y+3) = 3 ( x-1) expand and rearrange
y -3 = 3x- 3
y = 3x - 6
Let x be the score Amaya gets on the final test. She wants her average of all 3 tests to be between 80 and 89:
<span>80 ≤ (78 + 91 + x) / 3 ≤ 89 </span>
<span>Multiply everything by 3: </span>
<span>240 ≤ 78 + 91 + x ≤ 267 </span>
<span>240 ≤ 169 + x ≤ 267 </span>
<span>Subtract 169 from everything: </span>
<span>240 - 169 ≤ x ≤ 267 - 169 </span>
<span>71 ≤ x ≤ 98 </span>
<span>Answer: </span>
<span>She needs to score between 71 and 98 to get a B for the course.</span>

Answer:
he is faster than 95% of his team
Step-by-step explanation:
To finde this
First: Add Miguel to his 19 people equals 20 people
Next divide the 19/20
Providing the answer 0.95
to get the percentage multiply the decimal by 100: 0.95*100
= 95%
