10 PTS!!!! PLEASE HELP ALGEBRA 1 MATH
Alex787 [66]
Parallel lines will always have the same SLOPE. In the case of this equation, the slope is 1 since x is the same as 1x and the coefficient of x is the slope. Because there is no y, the graph of the equation will NEVER intercept the y-axis. Therefore, whatever answer option does not have y is correct.

Answer: C. x=2

Here's the graph to help you visualize:

A race car moving along a circular track has a centripetal acceleration of 15.4^2. If the car has a tangential speed of 30 what
Dominik [7]
In uniform circular motion (circular motion at same speed), (tangential velocity)^2/radius = acceleration towards the center of the circle (centripetal acceleration) 
<span>Also, radius is the distance to the center of the circle (track). </span>
<span>So, in your case, 15.4m/s^2 = (30.0m/s)^2/(radius) </span>
<span>radius = (900.m^2/s^2) / (15.4m/s^2) </span>
<span>radius = 58.4m</span>

What is the answer to -1/3 - -9/4
dangina [55]

Answer:

\frac{23}{12}

Step-by-step explanation:

Start by making a common denominator. In this case, it would be 12.

Multiply -1/3 by 4 to get -4/12

Multiply -9/4 by 3 to get -27/12

Then subtract

- \frac{4}{12} - (- \frac{27}{12} ) =23/12

You can also visualize this on a number line. Once you've made the denominator the same, start at -4/12 and move 27 units to the left to land on 23/12.
