Answer:
A is the correct answer.
By definition, a function is a relation where each input has exactly one output. In letter A, the inputs 0, 1, 2, and 3 all have exactly one output.
In B, the input 1 has two outputs.
In C, the input 2 has two outputs.
In D, the input 2 also has two outputs.

The system of linear equations x + y = 35 and y = 4x represents the two numbers
<u>Solution:</u>
Given that, The sum of two numbers is 35
The second number, y, is equal to 4 times the first number "x"
We have to find which system of linear equations represent the two numbers? We have two conditions for two variables, so we can obtain two equations, which means a system of equations.
Now, 1st condition ⇒ sum of two numbers is 35 ⇒ x + y = 35
And, 2nd condition ⇒ second number is 4 times the first number ⇒ y = 4x
Hence, the equations, x + y = 35 and y = 4x represents the given numbers.
General form of any equation is of the form AX+BY+C=0
Here A,B,C are three real numbers
THe given equation is
2x +4y+2=3y+5
To make right side equal to 0 we subtract 3y and 5 both sides
2x+4y+2-3y-5=0
Simplifying like terms
2x+y-3=0
Option B is the right answer
Answer:
15
Step-by-step explanation:
800 = 120
100 = x (number we have to find)
800x = 12000
x = 12000 ÷ 800
x = 15
