It could either be 11:9 or 11.../9...
(The dots stand for what the problem is talking about,for example 11 hot dogs per $9
Whereas the vertex of the graph of the function f(x) = x^2 is (0, 0), the vertex of the graph of the function g(x) = -8x + x^2 + 7 = (4, -9).
The vertex of the graph of the function g(x) = -8x + x^2 + 7 is 4 units to the right and 9 units down of the vertex of the graph of the function f(x) = x^2.
The answer is X=3
Hope this helps!
Answer: 2) 15 square units
Step-by-step explanation:
Answer:
5x +y = 34
Step-by-step explanation:
Since a point and slope are given, it is convenient to start with point-slope form, then rearrange the equation to put it into standard form.
For slope m through point (h, k), the point-slope form of the equation of a line is usually written ...
y -k = m(x -h)
For m=-5 and (h, k) = (6, 4), the equation is ...
y -4 = -5(x -6)
y -4 = -5x +30 . . . . . eliminate parentheses
__
Standard form looks like ...
ax + by = c
where a > 0 and GCD(a, b, c) = 1. Here's how we can get there.
5x +y -4 = 30 . . . . . . add 5x
5x +y = 34 . . . . . . . . . add 4 to get standard form.
