Answer:
1/5x - 12 = -7
Step-by-step explanation:
The first thing says 12 less THAN. Normally, when you see something in word problems like "less than" it means you need to switch the places.
So rather than 12 - 1/5, it's 1/5 - 12.
1/5 of a number means you are multiplying that number by 1/5. we'll use x (or any letter really, doesn't matter) to represent the unknown number.
Remember that if a variable and number is written together, it means multiplication.
So, 1/5x - 12 = -7.
B d and f it is getting larger, 3*2 is 6 meaning the scale factor is two, and point o is the vertex i think
Answer:
All real numbers
Step-by-step explanation:
![-2(y - 4) = 20 - 2y - 12](https://tex.z-dn.net/?f=-2%28y%20-%204%29%20%3D%2020%20-%202y%20-%2012)
Start by distributing -2 inside the parentheses.
![-2y + 8 = 20 - 2y - 12](https://tex.z-dn.net/?f=-2y%20%2B%208%20%3D%2020%20-%202y%20-%2012)
Combine like terms on the right side of the equation.
![-2y + 8 = 8 - 2y](https://tex.z-dn.net/?f=-2y%20%2B%208%20%3D%208%20-%202y)
Subtract 8 from both sides of the equation.
![-2y =- 2y](https://tex.z-dn.net/?f=-2y%20%3D-%202y)
Divide both sides by -2 to isolate y.
![0=0](https://tex.z-dn.net/?f=0%3D0)
This is a true statement, so there are infinite solutions.
D. Because it has and end and is a sequence where each number changes by a defined value.
