485, because the mean means you need to calculate the average. to find the average, you take the smallest number from the data set and the largest number. add the largest number by the smallest number and divide by the set of numbers you added (2). Example: (720+250=970 divided by 2 =485)
55% of 200=110. This is the answer. I hope this helped you a lot it look like you really needed it!!
"<span>F(x)=-1/2x^2+4 Important: enclose -1/2 inside parentheses.
vertex: For quadratic y=ax^2+bx+c, x value at vertex is -b/2a.
min or max: Corresponds to vertex x value; must also find y value
axis of symmetry: Same as x=value of vertex
y-intercept: Set x=0 and solve for y
domain: Domain is "all real numbers" when f(x) is a polynomial.
range:" Here, the graph opens down (because (-1/2) is negative), so the
range begins at -infinity and extends up to and including the y-
value at the vertex.
</span><span>F(x)= (-1/2)x^2+4
vertex: Since a = -1/2 and b = 0, x-value at vertex is -b/(2a), or
-(0) / (2[-1/2]) = 0. Graph is symmetric about the y-axis.
The function is F(x) = (-1/2)x^2 +4. At x = 0, y=4.
Thus, the vertex is at (0,4).
maximum occurs at the vertex, and is (0,4). Max value of function is 4.
axis of symmetry: see "vertex," above. x = 0 is that axis.
domain: since this is a polynomial function, the domain is the set of all real numbers.
range: (-infinity, 4] This includes y =4 and all smaller y values.
y-intercept: Set x=0 and find y. As before, y=4. y-intercept is (0,4).</span>
Answer:
y=1/4x-9
Step-by-step explanation:
Slope-intercept form is y=mx+b.
8y-2x=-72
Add 2x to both sides
8y=2x-72
Divide both sides by 8.
y=1/4x-9
HTH :)
Answer:
1.5
Step-by-step explanation:
Given the pair of points on the table.
Now the formula for slope, 
To calculate the slope we only require two pair of points.
Let us take: 
The slope of the linear function represented by the values in the table is 1.5.
Note: You can use any two set of values. The result will be the same.
