My mistake, answer must be put in y=mx+b. x+2y=0, you'd want to get y by itself, subtract x and divide by 2y, to get y by its lonely. The slope would be -1/2, the correct answer is A
1. Multiply the second line by 4: 4x+4y=16. They are the same line so there are infinitely many solutions.
2. Substitute for y.
x+(2x+10)=-2
3x+10=-2
3x=-12
x=-4
Plug x in
-4+y=-2
y=2
Final answer: (-4,2)
3. The answer is the first one because the solution is always where two lines intersect. The crossing of the x axis, y axis, and origin are irrelevant.
4. 2x+4=3x+1. This is because both equations define the value of y and therefore must be equivalent.
5. Infinitely many solutions. If you multiply the second equation by -3, you can tell it's coinciding or the same line.
Answer:
4 x 3 x n + 4 = 4 x n + 64
Step-by-step explanation:
did u want me to solve it too?
Distribute 1st or subtract 90 and 3 first and then multiply by 15
