Answer:
Chinese noodles
Step-by-step explanation:
Incident has been made and that the police will not allow the police to take the police to the police station to the police to help us to ensure they have their own safe and safe and safe driving system to ensure they have a safe driving license and the police will provide not to waste any of their baggage protection before the police check out the information contained in the police report
If you look at the data, you can see that every y value is opposite to the corresponding x- value.
So, equation can be written as
y = [-] x or y=[-1]x
Answer:
-3
Step-by-step explanation:
First find the slope, m:
2-(-1) 3
m = -------------- = --------- = 6/7
(1/2)-(-3) 3.5
Now use the slope-intercept formula:
y = mx + b
Choosing the point (1/2, 2), 2 = (6/7)(1/2) + b. Find b (the y-intercept):
14 [ 2 = (6/7)(1/2) + b ] => 28 = 6 + 14b.
Then 22 = 14b, and b = 22/14.
Then the eqn of the line is y = (6/7)X + 22/14
Mult. all terms by 14 to remove the fractions:
14y = 12x + 22
Finally, rearrange the terms: -12x + 14y - 22 = 0. This is the eqn in standard form, as requested.
Answer:
x = 2
, y = -7
Step-by-step explanation:
Solve the following system:
{y = 1 - 4 x | (equation 1)
{y = -2 x - 3 | (equation 2)
Express the system in standard form:
{4 x + y = 1 | (equation 1)
{2 x + y = -3 | (equation 2)
Subtract 1/2 × (equation 1) from equation 2:
{4 x + y = 1 | (equation 1)
{0 x+y/2 = -7/2 | (equation 2)
Multiply equation 2 by 2:
{4 x + y = 1 | (equation 1)
{0 x+y = -7 | (equation 2)
Subtract equation 2 from equation 1:
{4 x+0 y = 8 | (equation 1)
{0 x+y = -7 | (equation 2)
Divide equation 1 by 4:
{x+0 y = 2 | (equation 1)
{0 x+y = -7 | (equation 2)
Collect results:
Answer: {x = 2
, y = -7
