The parabola is looking down, so it can be A. or D.
The colored area is inside the parabola, that means that values of y inside the parabola is less than values of y of the parabola.
So,
the answer is D. f(x)< -x²+x-1
Answer:
the relation is a function, determine whether the function is ... to y = 2x + 2 a. Il slope = 2 b. ... Change to the slope- intercept form: (show work below) -_y 2x+1. 4- 5= 2(x+3).
Let x = the vertex angle so 30 + x = the base angle.
The sum of the three angles = 180 degrees. Set up an equation then solve.
x + 30 + x + 30+ x = 180
3x + 60 = 180
Subtract 60 from both sides
3x = 120
Divide both sides by 3
x = 40 => => Vertex Angle
x + 30 = 70 => => Base Angles
Answer:
Step-by-step explanation:
Answer:
Let x be the numbers of cones sold and y be
profit for the selling of cones.
When number of cones (x) increases then profit must be increased.That means, y is directly proportional to x
only one equation y = 2x satisfy this condition. all other equations does not satisfy the condition.
y = 2x gives that if the x number of ice cream sold the the profit made is 2x.
y = 8 + x (all time profit is number of item plus 8)
y = x – 8 (all time profit is number of item minus 8)
y = 2x – 8 (all time profit is 2 times number of item plus 8)
y = 2x Each item get Rs.2 profit. It is valid
