F(x) = -(x2+x-72)
y = -(x - 8)(x + 9)
the solutions are x = 8, -9; so the parabola is upside down (umbrella) crossing the x at 8 and -9, meaning that -9 + 8 = -1/2 = -0.5 is where the focus is, or x = -0.5 as the axis of symmetry
Answer:
164
Step-by-step explanation:
You can use a calculator or use long division
9x + 3 = 7x +19
2x + 3 = 19
2x = 16
x = 8
So, x (8) is the number of chairs in each row with these setups.
9(8) + 3 = 75
There are 75 chairs total
Ok Gudrunverizuensievr sorry
Answer:
y ≤ -2x - 2
Step-by-step explanation:
Given question is incomplete: Find the complete question in the attachment.
Since the graphed line is a solid line and passes through two points (-2, 2) and (0, -2).
Equation of the line will be,
y = mx + b
Where m = slope of the line
b = y-intercept
Slope of the line 'm' =
=
= -2
Y-intercept 'b' = -2
Therefore equation of the line will be,
y = -2x - 2
Since the shaded region is on the left side of the solid line,
Equation of the inequality will be y ≤ -2x - 2
