13+4x=1-x
4x=-12-x (minus 13 from each side)
5x=-12 (add x to each side)
You divide -12 by 5x
-12÷5x=2 $\frac{2}{5}$ ⇒2.4
x=2.4

Simplifying 13 + 4x = 1 + -1x
Solving 13 + 4x = 1 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.13 + 4x + x = 1 + -1x + x
Combine like terms: 4x + x = 5x 13 + 5x = 1 + -1x + x
Combine like terms: -1x + x = 0 13 + 5x = 1 + 0 13 + 5x = 1
Add '-13' to each side of the equation. 13 + -13 + 5x = 1 + -13
Combine like terms: 13 + -13 = 0 0 + 5x = 1 + -13 5x = 1 + -13
Combine like terms: 1 + -13 = -12 5x = -12 Divide each side by '5'. x = -2.4 Simplifying x = -2.4

Kolby decided he wanted to go to the amusement park. The amusement park charges $8.00 for entry and $1.40 for each ride.

Dmitry_Shevchenko [17]

Answer:

Part A:

1.40x+8.00=C

Part B:

1.40x+8=26

-8 -8

1.40x=18

/1.40 /1.40

x=11 total rides

Step-by-step explanation:

An expression to represent this would be 1.40x+8.00=C (C is total cost).

If you had $26.00 you would first spend $8.00 on the entry leaving you with $18.00. Then you would divide the $18 by $1.40 for each ride to get 12.8... It doesn't make sense to go on a fraction of a ride so you just round down to 11 rides

Describe the graph of of the equation x = -2. Is the equation a function?

Cloud [144]

In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot.

If x-intercept is -2 the line would be vertical as the y-intercept = 0.
