Answer:
slope = -3, y-intercept y = -2
Step-by-step explanation:
- Make y the subject of the line 2y + 4 = - 6x
- Divide throughout by two to get the slope of the graph as -3.
- Substitute x = 0 to get the y - intercept as y = -2
35 brownies were brought to class by Lauren
3% interest on 5,000 = 150
275 (the total amount wanted) - 150 (from initial investment)= 125
x (5%) =125
x (0.05)= 125
x/0.05)= 125/0.05
x=2500
you need to invest 2500 at 5% to get the additional 125
125 plus 150= 275
