x is directly proportional to y. When y = 7, x = 28. Write and equation of x in terms of y. Find x when y = 15.

Answers

Answer 1

Answer:

60

Step-by-step explanation:

28 : 7 : : x : 15

28 / 7 = x / 15

4 = x / 15

x = 4 * 15

x = 60

Answer 2
x = ky— directly proportional

28 = 7k

4 = k

so x = 4y

plug in y and you get x = 4(15) = 60

Therefore, x = 60 when y = 15

The total cost of renting a banquet hall is a function of the number of hours the hall is rented. The owner of the banquet hall charges $85 per half hour up to a maximum of 4 hours plus a $50 cleaning fee. What is the greatest value in the range for this situation?
What is the slope of the line that passes through the points (26, 7) and (-39, 12)

Answers

Answer:

It would be $390 for the 4 hours and the cleaning fees. And the slope would be -13 if you are going from 12 to 7 but would be 13 if you are going from 7 to 12...

Smith was the top scorer in a​ women's professional basketball league for the 2006 regular​ season, with a total of 850 points. The number of​ two-point field goals that Lindsey made was 57 less than double the number of​ three-point field goals she made. The number of free throws​ (each worth one​ point) she made was 41 less than the number of​ two-point field goals she made. Find how many free​ throws, two-point field​ goals, and​ three-point field goals Lindsey Smith made during the 2006 regular season.

Answers

Answer:

She made 138, 179 two point field goals and 118

3-point field goals during the regular season

Step-by-step explanation:

Answer:

118, 138, and 179 points

Step-by-step explanation:

x = 3-point goals

2-point goals = 2x - 57

free throws = 2x - 57 - 41

3x + 2x * (2x - 57) + (2x - 57 - 41) = 850

3x + 4x - 114 + 2x - 98 = 850

9x = 1062

x = 118

2x - 57 = 2 * 118 - 57 = 179

2x - 57 - 41 = 138

. A straight line passes through the point (-1,2) and its distance from the origin is
one unit. Find its equation.

Answers

Answer:

y = -1/2x + 3/2

Step-by-step explanation:

(2-0)/(-1-0) = -1/2

2 = -1/2(-1) + b

2 = 1/2 + b

b = 3/2

Answer: y = -1

Step-by-step explanation:

Assuming "distance from the origin is one unit" means distance on the x axis, a vertical straight line having an x-intercept of -1 would satisfy thede requirements.  y = -1 isn't much of an equation, but it goes through (-1,2) and is 1 unit (-1) from the origin.
