Answer:

a = -3

Step-by-step explanation:

3a−6a+2=8a+20−5a ( original equation)

Step 1: Simplify both sides of the equation.

3a−6a+2=8a+20−5a

3a+−6a+2=8a+20+−5a

(3a+−6a)+(2)=(8a+−5a)+(20)(Combine Like Terms)

−3a+2=3a+20

Step 2: Subtract 3a from both sides.

−3a+2−3a=3a+20−3a

−6a+2=20

Step 3: Subtract 2 from both sides.

−6a+2−2=20−2

−6a=18

Step 4: Divide both sides by -6.

−6a/−6 = 18/-6

a=−3

Answer:

(a) 3118=61*t

(b) The amount of time the roller coaster is in motion is 51.11 seconds.

Step-by-step explanation:

Speed is a magnitude that expresses the relationship between the space traveled by an object, the time used for it and its direction. In other words, speed is associated with the change in position of a body over time and can be expressed as:

$speed=\frac{distance}{time}$

Then the distance traveled can be expressed as:

distance=speed*time

(a) If x represents the total time that the roller coaster is in motion for each ride, the average speed is 61 feet per second and the distance is 3118 feet then the expression to represent the situation is:

3118=61*x

(b) To calculate the amount of time the roller coaster is moving, you simply need to solve the expression found in (a). Dividing 61 to both sides:

$\frac{3118}{61} =\frac{61*x}{61}$

51.11 seconds=x

The amount of time the roller coaster is in motion is 51.11 seconds.

you look at were the graph starts to decrease then look at the X-VALUE not the y-value

the x-val at the start of the decrease is -3 and at the end of it it is 2 therefor -3 $\leq$ x $\leq$ 2

Would the -5 go to the left or the right on the number scale?

jeyben [28]

The number -5 would go to the left of a number scale. Typically because all negatives move to the left of zero on the number scale.
