Given:
Connor runs at a constant rate.
It takes him 34 minutes to run 4 miles.
To find:
The linear equation in two variables that represents the given situation.
Solution:
Let y be the distance covered by Connor in miles and x be the time in minutes.
It is given that Connor needs 34 minutes to run 4 miles. So, the linear equation passes through the point (34,4,) and the rate of change is:
Using the point slope, the equation of the linear function is:
Therefore, the correct option is D, i.e., .
Answer:
54
Step-by-step explanation:
12+2x=120
2x=108
x=54
The sale price is 4/5 of the original price...with x being the original price
4/5x
0.8x
these are the same because 4/5 = 0.8..its just in decimal form
Answer:
1; -1
Step-by-step explanation:
As x approaches 0 from the left, the graph goes up to the point (0, 1), where the solid dot indicates that is the function definition for x=0.
As x approaches 0 from the right, the graph goes down toward the point (0, -1), to which it comes arbitrarily close. The limit from that direction is -1.
The two limits are +1 and -1.
Answer:
Step-by-step explanation:
8+1=9
8/9 ×100=800/9=88 8/9 %
1/9×100=100/9=11 1/9 %
