Answer: 0.194
Step-by-step explanation:
First step is to open the brackets.
7(19 - 9))/(4 * 5 * 18) = (133 - 63)/360
= 70 / 360
= 0.194

======================================================
Explanation:
The fraction 1/4 is equivalent to the decimal form 0.25
We multiply 0.25 with each coordinate, of each point.
For example, let's focus on point L which is at (2,-1)
- x = 2 becomes x = 0.25*2 = 0.5
- y = -1 becomes y = 0.25*(-1) = -0.25
Point L(2,-1) moves to L ' (0.5, -0.25) which will move it closer to the origin, which shrinks the image. Use this idea for the remaining points.
Note: this trick only works if the center of dilation is the origin.
Answer:11
Step-by-step explanation:Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
3*(x-5)-(18)=0

Pulling out like terms
3.1 Pull out like factors :
3x - 33 = 3 • (x - 11)
Equation at the end of step

:
Equations which are never true:
4.1 Solve : 3 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation:
4.2 Solve : x-11 = 0
Add 11 to both sides of the equation :
x = 11
One solution was found :
x = 11
Answer:
3 + 4x
Step-by-step explanation:
Let "a number" be x.
Therefore "four times a number" is 4 multiplied by x which is 4x.
Now add 3 for "3 plus".
3 + 4x
