Answer:(-1,2), (6,8), (5,-7)
Step-by-step explanation:
The function
is incresing and have positive values for all x. Then the function
is also increasing and have positive values for all x. This means that options B (values are negative) and D (function is decreasing) are incorrect.
At x=0,
.
In option A graph of the function passes through point (0,y), where y is near 3. In option C graph of the function passes through point (0,y), where y is near 1/5. So, you can conclude that the option C is correct.
Answer:
10 gallons 12 seconds.
Step-by-step explanation: The arrow is at 10 and pointing where 12 is.
50 + 70h = 450
70h = 450 - 50
70h = 400
h = 400/70
h = 5.71.....to the nearest hr, it would be 6 hrs <=
Y = mx + b, where m is the slope, and b is the y-intercept. If we were to consider a line of best fit that would represent all these points with a linear line, it'd cross the y-axis with a y-value of 10, so we can fill in y = mx + b to y = mx + 10. Now, it runs down from left to right, so we know the slope must be negative. The only equation that fits this description is y= -3/4x + 10
