Answer:
175 miles
Step-by-step explanation:
Hillary has travelled
320 + 350 = 670 miles
in the first two weeks.
Therefore, Hillary starts with 670 miles and needs to add a certain number of miles "x" to get 845 in total.
670 + x = 845
And if we subtract 670 from both sides:
x = 845 - 670 = 175
175 miles
First find the slope, (y2-y1)/(x2-x1)=(20-10)/(40-20)=10/20=1/2
y=mx+b, where m is the slope and b is the y-intercept
y=x/2+b, using any point we can solve for b, I'll use (20, 10)
10=20/2+b
10=10+b
0=b, so the cost function is:
C(m)=m/2 (cost in dollars as a function of minutes is minutes divided by two)
Answer: First option.
Step-by-step explanation:
For this exercise it is importnatn to to remember the properties that are shown below:
1)
2)
Therefore, given the following expression provided in the exercise:
You can apply the properties mentioned before, in order to find an equivalent expression.
Therefore, you get:
Then the answer is the first option.
Answer:
11
Step-by-step explanation:
If you notice the x values 5, 7, 9, x you'll see thy are going up by adding 2.
do 9 + 2 = 11
3times figure number plus the 4 original.
3n +4= number of circles in figure
So (3times23)+4= number in 23 figure (73)
Then 3n+4= 82
-4 from each side to keep equation balanced (78) then divide 78 by three which equals 26.
