F(x) = x+4
f(4) = 8, f(5) = 9
Change = 1
f(x) = 3x-7
f(-3) = -16, f(5) = 8
Change = 24/8 = 3
f(x) = 9x+1
f(-5) = -44, f(-2) = -17
Change = 27/3 = 9
f(x) = 2x+9
f(1) = 11, f(2) = 13
Change = 2
In order: f(x) = 9x+1, f(x) = 3x-7, f(x) = 2x+9, f(x) = x+4
Answer:
Option D
Step-by-step explanation:
' y = 4x − 1' would graph as a straight line. Therefore, it is a linear equation.
Liner equations are graphed as a straight line, while nonlinear equations are not.
Answer:
Our two numbers are 50 and 20
Step-by-step explanation:
Sum means add together
Difference means subtract each other
x + y = 70
x - y = 30
subtract from each other
2x = 100
divide both sides by 2
x = 50
our first number is 50
50 + y = 70
subtract both sides by 50
y = 20
Our two numbers are 50 and 20

Answer:
The fraction is = 
Step-by-step explanation:
In simplest form the fraction is represented in mixed number as
.
The fraction form of the mixed number can be given as :

Let the fraction be =
[As multiplying same numbers to numerator and denominator does not affect the proportion.
Sum of numerator and denominator is = 30
This, can be represented as:

Solving for
.

Dividing both sides by 10.


So, the fraction will be = 
⇒
