Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!

Answer:
As per the statement:
Here, x represents the total sales in dollars
Total weekly pay of Alexa in dollar is represented by:
and
Total weekly pay of Samantha in dollar is represented by:
We have to find the value of x, in dollars that will make their weekly pay the same.
⇒
Substitute the values we have;
Subtract 250 from both sides we get;
Subtract 0.085 x from both sides we get;
Divide both sides by 0.01 we have;
Simplify:
x = $16300
Therefore, $16300 that will make their weekly pay the same
Answer:
B. 80 km/h
Step-by-step explanation:
The graph is linear and goes through the origin, so distance is proportional to time, and the constant of proportionality is speed. The desired answer can be read from the point on the graph at time = 1 hour: 80 km.
Julian's speed is 80 kilometers per hour.
