Which equation represents a line that has a slope of -1/2 and passes through point (4, –5)?
Wewaii [24]
Y=-1/2x-3

You can rewrite the equation “y=mx+b” and fill in what you know. So your equation would look like y=-1/2x+b when filling in what you know. Now you can take the (x,y) coordinates that you were given and plug them into the equation and solve for b. So now it would be -5=-1/2(4)+b

A​ student's course grade is based on one midterm that counts as ​% of his final​ grade, one class project that counts as ​% of
Andrei [34K]

Answer:

The overall score is 75.6

Letter grade is C

Step-by-step explanation:

The question has missing details (See comment section for complete question).

From the complete question, we have:

<u>Proportion:</u>

Midterm = 15\%

Project = 25\%

Assignment = 40\%

Exam = 20\%

Scores

Midterm = 66

Project = 90

Assignment = 75

Exam = 66

Solving (a): The overall score

To do this, we simply calculate the mean of the given data.

The mean is calculated by multiplying each proportion by the scores..

So, we have:

Overall = 15\% * 66 + 25\% * 90 + 40\% * 75 + 20\% * 66

Overall = 9.9 + 22.5 + 30 + 13.2

Overall = 75.6

Solving (b): The letter grade

From the question, we have:

A: Mean \ge 90

B: 80 \le Mean < 90

C: 70 \le Mean < 80

The overall score falls in the following category:

C: 70 \le Mean < 80

Because:

70 \le 75.6 < 80

<em>Hence, the letter grade is C</em>
