Hello :
f(x) = <span>√(0.5x-10) +3
</span>inequality can be used to find the domain of f(x) is : 0.5x-10 <span>≥ 0
</span>0.5x ≥10
x ≥10/0.5
x ≥ 20
the domain of f(x) is : D = <span>[</span><span>20 ; + ∞[ </span>
Well using mental math, subtract .04 from 1.6 to get 1.56, which is s
Answer:
x = 13
Step-by-step explanation:

Take the square root of both sides

Answer:
-2x + 3
Step-by-step explanation:
Trust me, this is the answer.
An explanation:
Slope is rate of change.
if the lady sells 2 cakes in 3 hours, her rate of change, or slope is 2/3.
Y-intercept is where the data enters the graph. It will not always be at the origin of the graph. If on the lady's first day of business, she sold 10 cakes, the Y-intercept is 10. This equation of the lady's business in slope intercept form would be 2/3x + 10. ALWAYS write the slope before x and the y intercept after the + or -- , hope this helps, but -2x + 3 is your answer for sure.
