The correct answer is A: x=2 and y=-3. Either method would work, but for example, let's use elimination. If you multiply the second equation by 5, you get: 10x +5y = 5. When you add both equations, you can then cross out both y terms. You are left with one equation that reads: 13x=26. Solving for x gives you 2. You can substitute 2 in for x in either equation and you will receive -3 for your y value.
The slope is -2. The y-intercept is (0,1).
Answer:
-9
Step-by-step explanation:
-3x+y=-7
-3x+y-2
-7-2=-9
9/15 becomes 90/15 but now u have a point on ur answer so it would be .6 as 15 times 6 equals 90
Answer:
x=4 and y=2
Step-by-step explanation:
Name the triangles as ABC and DEF,
Now, since both the triangles are congruent by HL rule, therefore
(1)
and 
(2)
Substituting the value of in equation (1), we get
Therefore, Putting y=2 in equation (2),
