Answer:
y ≤ 5/2x + 7
Step-by-step explanation:
Rearrange the inequality so it looks like y = mx+b or in other terms, the y is on the left and everything else is on the right.
5x - 2y ≥ -14
-5x -5x
-2y ≥ -5x - 14
/-2 /-2 /-2
y ≤ 5/2x + 7
i changed the direction of the inequality sign because i divided everything by a negative 2.
Answer:
Step-by-step explanation:
The equation is 3.95m + 8.95b = 47.95 where m is the amount of magazines bought and b is the amount of books bought. 47.95 is the total spent. We know that he bought 3 magazines, so we can switch m with 3. 3.95 multiplied by 3 is 11.85. The equation is now 11.85 + 8.95b = 47.65. Subtract 11.85 from both sides to get b by itself. 8.95b = 35.8. Divide both sides by 8.95 to get b by itself. b = 4
