Answer:
y= -2
x = 5
Step-by-step explanation:
Multiply the top equation by 2 to get
2x + 6y = -2
then subtract the bottom equation by the new equation to get
2x + 6y = -2
--------------------
2x + 2y = 6
which is
4y = -8
y = -2
If y = -2
Then plug -2 into y in the top equation to get x + 3(-2) = -1 and simplify which is
x + (-6) and add 6 to both sides to get x = -1 + 6
which is x = 5
Answer:
The measurements do not form right angled triangle.
Step-by-step explanation:
Given lengths are 5 mm, 12 mm and 17mm
The longer leg forms the hypotenuse of the right angled triangle.
Using Pythagorean theorem;
Therefore,
The measurements do not form right angled triangle.
<span> y = 5x + 6
y = −x − 7
5x + 6 = -x - 7
6x + 6 = -7
6x = -13
x = -13/6
y = 5(-13/6) + 6
y = -29/6
The solution is (-13/6, -29/6) and that tells us that the two ines do not intersect at the origin or any of the two axis. If they intersected at the origin, then the solution should have been (0, 0). If they intersected at the x-axis, the solution should have been (x, 0). If the two lines intersected at the y-axis, the solution would have been (0, y).
The answer is A) </span><span>Line y = 5x + 6 intersects line y = −x − 7.</span>
