9≤c + 1
In this question we will first solve for the variable. ( i.e. c )
so,
subtracting both sides by 1 we get
8 ≤ c
or
c ≥ 8
And we know that if we have ≤ or ≥ we have a HARD dot on the point.
So, our graph will start from point 8 goes to the right.
hope this helped.. :)
You got it correct
about + - 10.4
Answer:
Option A.
Step-by-step explanation:
Consider the given problem is

Using the properties of radical expressions we get
![[\because \sqrt{\frac{a}{b}}=\frac{\sqrt{a}}{\sqrt{b}}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7B%5Cfrac%7Ba%7D%7Bb%7D%7D%3D%5Cfrac%7B%5Csqrt%7Ba%7D%7D%7B%5Csqrt%7Bb%7D%7D%5D)
![[\because \sqrt{ab}=\sqrt{a}\sqrt{b}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5Csqrt%7Bab%7D%3D%5Csqrt%7Ba%7D%5Csqrt%7Bb%7D%5D)

Taking out common factors.



The simplified form of given expression is 
Therefore, the correct option is A.
Answer:
Step-by-step explanation:
Let x represent the amount that he paid for one hamburger.
Daniel buys lunch for his family from a food stand. He purchased one hot dog for $2.50 and 3 hamburgers. The cost of 3 hamburgers would be 3x.
If he spent a total amount of $13 on the hot dog and hamburgers, it means that
2.5 + 3x = 13
3x = 13 - 2.5 = 10.5
x = 10.5/3
x = $3.5
