Answer:
Mallory flew in total 10,000 miles, rounded :D
Step-by-step explanation:
<em>Since we're using rounding to place values, first we have to have the total amount of miles flown by Mallory, so we make the sum:</em>
3,720 + 5,985 = 9,705 miles
<em>then, we have to round thefirst digit to the right following this rule</em>
0-4 is rounded down
5-9 is rounded up
<em>now, since the number we want to round is the first digit on the left (9), and following the rules above, we change the "9" for a "10". the rest of the numbers are now transformed into zeros (0)</em>
9,705 >>> rounding it up >>> 10,000
Let me know if you have any questions XD
Answer:
B
Step-by-step explanation:
90+45+45=180
All triangles equal 180.
Its B because if one angle is 90° then the other angles will equal each other. It cant be 60° and 30° because they dont equal, so your final answer is B.
Hope this Helps!!! :)
1. This is a very easy question as you can just plug in 2 x-values and get the y-value, run a line through it, and you are done.
For example,
x = 2t
x = 2(2) = 4
x = 2(3) = 6
Now, you know there are points at (2, 4) and (3, 6).
2. This one is a little tricky, but all it's saying is that it has a specified domain. The parametric equation only works for values -2 ≤ t ≤ 3. So, you can do the exact same thing, except your line will only exist for points through the x-values -2 and 3. Let's plug in numbers:
y = t + 5
y = -2 + 5 = 3
y = 1 + 5 = 6
Now you know that this line runs through (-2, 3) and (1, 6). Remember, your line starts at -2 and ends at 3. It can't go any further than that.
