Write an equation in standard form Y+1=x+2

1 answer:

4 0

Standard form is when x and y are on one side of the equations and the constants are on the other side. Moving the variables and constants around we get, $-x+y=1$ However we have to make sure the x is not negative. Multiplying all by negative one we get x-y=-1

A train leaves Los Angeles at 2 p.m. heading north at 50 mph. If the next train leaves three hours later and also heads north at

Mamont248 [21]

Since the first train has been travelling for 3 hours, we have the following equations:
$d=50t+3*50=50t+150$
$d=60t$

We want to know when they will be equal, so set these equal to eachother:
$60t=50t+150$
$10t=150$
$t=15$

So 15 hours after the second train leaves, they will be at the same distance. This is at 8AM since the second train leaves at 5PM.

Assoli18 [71]

Answer:

Both Amy and Fraser walk distances equal to the radius of the lawn.

Step-by-step explanation:

The radius of a circle is a line segment from the center to the outside edge (circumference).

Amy walks from O, the center, to A, along the outside edge, using segment OA. This is a radius of the circle.

Fraser walks from O, the center, to B, along the outside edge, using segment OB. This is a radius of the circle.

Thus the correct answer is that both Amy and Fraser walk distances equal to the radius of the lawn.
