Answer:
graph 1 proportional
graph 2&3 is non proportional
i think
If the slope is 1 then u would find the coordinate (-4,7)and go up one and right one
The answer is x = 6
Let us first define x to be the number of hours of riding lessons she can take.
X = Hours of lessons
Now, she has $200, she needs to pay $20 for grooming supplies, and the lessons cost $30 an hour. We to find the maximum amount of hours of lessons she can take, so in other words, we want to make her broke. To do this, we first convert the words into an equation:
200 - 20 - 30x = 0
Simplifying, we get
180 = 30x
x=6
Answer: k=65
Step-by-step explanation:
Answer: [-π/2, π/2]
Step-by-step explanation: The range of 
is actually equal to the domain of y=sin x, but it wouldn't be a function, according to the definition of a function. But if you restrict the range, it becomes a one-to-one function.
