2 of the graphs are perpendicular lines.
One line has a slope of 2x the other line.
Answer: 231
Step-by-step explanation:
From the description, we have the function
Since the square root cannot be a negative number, the only thing need to do to find the domain of the function
is take the expression inside the square rot and set it greater or equal than zero:
or
We can conclude that we can use the inequality
to find the domain of
. Also, the domain of
is (∞,
]U(5,∞).
Answer:
B,B,C
Step-by-step explanation:
#1: Meat is usually in ounces, patties weigh not too much, but enough. reasonable estimate. #2: Oil is a liquid, used not too much in baking. #3: Must be equal to 16/5.
When you have an equation with two variables, it's easier to graph it in the form y=mx+b. b is the y-intercept - the x-value at which y is equal to zero, and m is the slope of the graph.
So if I have the equation 3x+2y=12, I have to first subtract 3x from both sides.
2y=-3x+12. Now I have to divide the whole thing by 2 to get my y value alone. y=-3/2x+6.
Now, to graph it, I have to first plot the point where y equals zero and x equals six. Then you plug in different numbers above and below this. When x=5, you get y=-3/2*5 + 6 which is -1.5. So you have the point (5, -1.5) and also the point (6, 0). You can plug in 0 for y and solve for x to find the x-intercept, or when x=0. 0=-3/2x+6. Subtract six from both sides. -6=-3/2x. Divide both sides by -3/2. 4=x. So you have another point - (4,0).
Now that you have three points, you can connect them with a line and add arrows to the end.
Hope I helped!
