The correct answer among the given choices is the first one:
“A graph shows Time in hours on the x-axis and Aida’s Distance from Tent
in miles on y-axis. The graph shows three straight lines. The first straight
line joins ordered pairs 0, 0 and 2, 4. The second straight line joins ordered
pairs 2, 4 and 8, 4. The third straight line joins ordered pairs 8, 4 and 9, 0.”
The given ordered pairs is in the format of (t, d) where t is time and
distance is d. Time will always be on the x-axis since it is always an
independent variable.
The first ordered pair should be (2, 4) since it took her 2 hours to
trek to the hilltop. From the given choices, only the 1st and 3rd
choice has this first ordered pairs so we are down to two choices.
Now the second ordered pair should be (8, 4) since she spent 6 hours at
the top but no change in distance. And only the 1st choice has this
value therefore it is the answer.
Answer:
12 units
Step-by-step explanation:
- chords
and
are equidistant (7.2 units) from the center of the circle O. - Measures of the chords equidistant from the center of the circle are equal.
![\therefore m(chord\:\overline{AN}) =m(chord\:\overline{ML})](https://tex.z-dn.net/?f=%20%5Ctherefore%20m%28chord%5C%3A%5Coverline%7BAN%7D%29%20%3Dm%28chord%5C%3A%5Coverline%7BML%7D%29%20)
![\therefore m(chord\:\overline{AN}) = 12\: units](https://tex.z-dn.net/?f=%20%5Ctherefore%20m%28chord%5C%3A%5Coverline%7BAN%7D%29%20%3D%2012%5C%3A%20units%20)
Y = 3x - 2
I assume this is what they mean;
3(1)- 2 = 1 for <span><span>x = 1
</span>Fill in the x's with the following numbers. so first... (x = 2)
</span>y = 3x - 2
3(2) - 2
multiply 3 and 2 and then minus 2
which equals 4 all together
y=4
therefore;
3(2) - 2 = 4
For x = 3
Fill in the x with 3 in the equation
3x - 2 = y
3(3) - 2 = y
9 - 2 = y
equals 7
so...
3(3) - 2 = 7
Do the same rule with number 4 :)
Let me know if it's different from what you're learning
S = 3+M
4(S + M) = 67
4(3+M + M) = 67
4(3+2M) = 67
12 + 8M = 67
8M = 55
M = 6 years 10 months 14 days @ 6.875 years
S = 3 + 6.875
S = 9 years 10 months 14 days
200,400,000,000= 200,000,000,000+400,000,000
Hoped I helped:D
