Answer:
John has $21.
Step-by-step explanation:
Let John's "wealth" be w. Then 2w+8 = 50, or 2w = 42, or w = 21.
John has $21. Eight more than twice this is 42+8 = 50, as expected.
Answer:
8.275
Step-by-step explanation:
Thanks bro!
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.
47 degrees put a protractor to it
Answer:
Step-by-step explanation:
First put a point at the location (1,2) on the coordinate plane. After that you need to go three points up and five right. Continue until you reach the edge of the plane. If the plane has four quadrants do the same going down, accept it will be starting at (1,2) going down 3 and left 5.
Hope this helps!!
