Answer:
x=2
Step-by-step explanation:
3(3x+10)=50−x
The first step is to distribute the 3
3*3x + 3*10 = 50-x
9x+30 = 50-x
Add x to each side
9x+x+30 = 50-x+x
10x+30 = 50
Subtract 30 from each side
10x+30-30 = 50-30
10x= 20
Divide each side by 10
10x/10=20/10
x =2
A function is linear if:
B. The function can be described by an equation of the form y = mx + b.
C. The function has a constant rate of change.
D. The function has a straight-line graph.
A function is said to be linear if it is a straight line graph and it can be represented by the equation:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
A linear function has a constant rate of change (either increasing or decreasing).
