<span>4(r+1.9)-9r=12.2
</span><span>4r + 7.6 -9r = 12.2
-5r = 12.2 - 7.6
-5r = 4.6
r = 4.6/-5
r = - 0.92</span>
The correct answer is 537
Answer:
The 4th graph
Step-by-step explanation:
To have a maximum value, your parabola would have to open downwards. So the first 2 are wrong. Since your y-intercept is positive 4, your graph would have to touch the y axis at 4. The 3rd graph is wrong since it touches the y-axis at a negative point. The correct answer would be the 4th answer choice.
