Answer:
400 < m< 430 kg
Step-by-step explanation:
the mass of horse is 429 kg
estimated to the nearest hundred is 400 kg
estimated to the nearest tens is 430 kg
thus the value of m mass lies between 400 to 430
therefore
400 < m< 430 kg
Answer: The answer is 5.6d+ 2.1
Step-by-step explanation:
Add then subtract then add then multiply then subtract then divide.
Answer:
3600 miles on 240 gal
Step-by-step explanation:
80 gal can go 1200
160 gal can go 2400
240 gal can go 3600
V=Vo (1-r/100)^n
V=46900(1-3.2/100)^8
V=46900(96.8/100)^8
V=46900*(.968)^8
V=36155.61
V=36155(approx)
To find the answer, you have to figure out the y-intercept and the slope.
The y-intercept is relatively easy. Look at the graph and locate the spot where the line passes the y axis. It passes at (0, 2), which means that the y-intercept is 2. So, we can eliminate two of the answers.
Now, on to the slope. Slope is the change in y over the change in x, or rise over run. We need at least two points to find the slope. The most obvious ones are the intercepts: (0, 2) and (-1, 0).
Change in y is the difference of the y coordinates: 2 - 0 = 2.
Change in x is the difference of the x coordinates, but this subtraction must be in the same order as the difference of the y coordinates: 0 - (-1) = 1
Change in y over change in x is:
2/1 = 2
So, the slope is 2.
Taking the whole problem, the equation in slope-intercept form is: y = 2x + 2.
The answer is D.
