Answer:
A
Step-by-step explanation:
To move something up or down, it means we're moving along the y-axis. So we need to change the y-coordinate.
To move it up, we'll be moving towards the positive end of the y-axis. On a coordinate plane, if you move anything "up," you're moving closer to the positive end of the y-axis.
To move it five units up, we need to move 5 units positively.
So our y is:
y + 5
To move something left or right, it means we're moving it along the x-axis. So we need to change the x-coordinate.
To move it left, we'll be moving it towards the negative end of the x-axis. Think about it: on a basic number line (which is what the x-axis is), the more you move towards the left, you move closer to 0, and therefore the negative end.
To move it 2 units left, we need to move 2 units negatively.
So our x is:
x - 2
Putting them together, we have:
(x, y)
(x - 2, y + 5)
Answer:
x=75, y = 50
Step-by-step explanation:
Solve the following system:
{x + y = 125 | (equation 1)
5 x + 8 y = 775 | (equation 2)
Swap equation 1 with equation 2:
{5 x + 8 y = 775 | (equation 1)
x + y = 125 | (equation 2)
Subtract 1/5 × (equation 1) from equation 2:
{5 x + 8 y = 775 | (equation 1)
0 x - (3 y)/5 = -30 | (equation 2)
Multiply equation 2 by -5/3:
{5 x + 8 y = 775 | (equation 1)
0 x+y = 50 | (equation 2)
Subtract 8 × (equation 2) from equation 1:
{5 x+0 y = 375 | (equation 1)
0 x+y = 50 | (equation 2)
Divide equation 1 by 5:
{x+0 y = 75 | (equation 1)
0 x+y = 50 | (equation 2)
Collect results:
Answer: {x = 75
, y = 50
