Answer:
To use the elimination method one coefficient of either x or y must be the same number with opposite signs, so the ordered pair is (-10, -8)
Step-by-step explanation:
2(-x+y=2) Make one of the coefficients equal, with opposite signs.
2x-3y=4 Combine equations.
-y=8 Solve, y=-8
Then find x, -x-8=2
-x=10, so x= -10
(-10, -8) is your answer.
Yes, they are its just that the other one is smaller. Otherwise, they are the same
Answer:
When a line has a slope of 1/3, it means it's going up 1 unit and to the right 3 units.
(Remember rise/run; in which rise is movement up or down, and run is movement left or right. )
Here's an example graphed above for you⤴⤴⤴
Hope this helps you :)
Answer:
The third angle measures 66°
Step-by-step explanation:
If we look at the properties of triangles, we will know that all triangles have angles that, when added together, equal 180 degrees. Because we already know the measurement of two of the angles, all we have to do is add them up and subtract the sum by 180.
57+57=114
180-114=66
We got 66 as the measure of the last angle. Now, to make sure we have the right answer, we are going to check our work. We do this by adding together all of the angle measurements. If they all add up to 180, then we know we have the correct answer.
57+57+66=180
We were correct! Now we have the measurements of all three of the triangle's angles. Great job!
I hope this is easy to understand. Please let me know if you need any more help. Have a great morning!
Answer:
smallest
largest
Step-by-step explanation:
First change the mixed numbers into an improper fractions.
= 
9 x 2 = 18 + 3 = 21
= 
27 x 3 = 81 + 1 = 82
= 
125 x 3 = 375 + 2 = 377
Find the least common denominator.
2 and 3 have 6
= 
smallest
= 
medium
= 
largest
