Marisa wants to buy a DVD player that runs for at least $150. She already saved $ 80 and plans to save an additional $ 10 each week. Write an inequality that represents this problem and explain your answer in detailed steps.
Answers
x=number of weeks the inequality is: 10x+80≥150
Now, we solve this inequality: 10x+80≥150 10x≥150-80 10x≥70 x≥70/10 x≥7
Solution: Marisa needs to save at least 7 weeks for she can buy the DVD

Which equation represents the graph of the linear function?A. y = 4x + 4
B. y = 4x − 4
C. y = −4x + 4
D. y = −4x − 4
Answers
By looking at the graph you can rule out choices C and D because the graph given to you is an increasing linear function and C and D represent functions with a decreasing or negative slope.
By looking at the picture the slop of the graph seems to be 4/1 (rise/run) so your slope is 4. And your y-intercept looks like its -4 so your answer is B
