Answer:
the ordered pair will be (1, 2)
Step-by-step explanation:
first of all substitute the x and y values into the equation in other to make the equation true.
Therefore y=4x-7
1 = 4(2) -7
1 = 8 -7
1 = 1
Making the first equation true. then move to the second equation which is y = - x + 3
1 = -(2) + 3
1 = 1
I hope this helps though
Answer:
-500
Step-by-step explanation:
If it's below it would be negative so -750 - 250
Answer:
2 because negatives arent greater than whole numbers
Answer:
Answer: {x = -2
, y = 5
Step-by-step explanation:
{x + 4 y = 18 | (equation 1)
{x + 8 y = 38 | (equation 2)
Subtract equation 1 from equation 2:
{x + 4 y = 18 | (equation 1)
{0 x+4 y = 20 | (equation 2)
Divide equation 2 by 4:
{x + 4 y = 18 | (equation 1)
{0 x+y = 5 | (equation 2)
Subtract 4 × (equation 2) from equation 1:
{x+0 y = -2 | (equation 1)
{0 x+y = 5 | (equation 2)
Collect results:
Answer: {x = -2
, y = 5
<span>y = 3x - 7
3 = slope
-7 = y intercept
This line would cross the y intercept at -7, and go up by 3 (slope). </span>
