13)The final grade on your math exam was determined by the function f(x) = 100 - 2x. Which statements are correct?
Yuki888 [10]

Answer:

A, B, D

Step-by-step explanation:

from this function, we can see that 2x is being subtracted from 100. x is the number of incorrect problems, so this can not be a negative value. therefore, the maximum score you can get is 100. y is equal to your final grade as calculating the right side of the equation results in the grade you receive based on the number of incorrect answers. this is a linear function since its highest power is 1. each question is worth 2 points as 2 is being multiplied by the number of incorrect questions (x).

A line connecting the points (-3,0) and (x, -6)has slope -1. Determine x.
ankoles [38]

Answer:

x=3

Step-by-step explanation:

We can use the slope formula to help complete this question

m = (y2-y1)/(x2-x1)

-1 = ( -6-0)/(x- -3)

-1 = -6/ (x+3)

Multiply each side by (x+3)

-x-3 = -6

Add 3 to each side

-x -3+3 = -6+3

-x =-3

Multiply each side by -1

x = 3

MARK AS BRAINLIEST PLZZZ

Answer:

Son + Daughter 60%

Son -  23,625

Daughter - 16,875

Wife % - 40%

Total - 67,500

Step-by-step explanation:

1. We do 35 + 25 to get 60

2. 27000 / 40 to get 1% = 625

Then, 625 x 35 = 23,625

3. 625 x 25 = 16,875

4. 100 -  60 ( kids )  = 40%

5. 40500 ( kids ) + 27000 = 67, 500
