Cheryl earns $25 for every house she cleans and $12 for every car she washes. She uses the expression 25x + 12y to keep track of her earnings. Part A: Identify the coefficients and variables in the expression. (2 points) Part B: How many terms are in the expression, what are they, and how do you know? (1 point) Part C: Which term in the expression shows the total earned from washing cars? (1 points) (4 points)

If f(x)=3x+1 and f^-1=x-1/3, then f^-1(7)=

Aretha wanted to gather data about the cost of local bowling leagues in her area. she plotted the data and determined that the average bowling league costs consist of a one-time registration fee and a monthly fee modeled by the equation y = 15x + 20. identify and interpret the y-intercept in this model. the y-intercept is 20. this is the cost per month. the y-intercept is 20. this is the cost of registration. the y-intercept is 15. this is the cost of registration. the y-intercept is 15. this is the cost per month.

Ialready asked this but i never got an answer. will give a high rating and perhaps brainliest. choose the linear inequality that describes the graph. the gray area represents the shaded region. y ≤ –4x – 2 y > –4x – 2 y ≥ –4x – 2 y < 4x – 2
