Answer:
function : 2 and 3
Step-by-step explanation:
a function cant have any overlapping points on the x axis, if you can draw a line up and down (vertical) and it hits two points then it isn’t a function
Direct variation describes - roughly - a relationship between two values where <em>scaling one value will scale the other by the same amount</em>. The x value <em>doubles </em>as it goes from 5 to 10, and since y varies directly as x, we can double the old y value to get the new one as well. Since the old y value is 8, our new y value should be 8 x 2 = 16.
If the given are h =2x+9, l = x+2, w = 3x, then the answer is 6x^3+39x^2+54x
V = lwh
= (2x+9)(x+2)(3x)
= (2x^2 + 4x + 9x + 18)(3x)
= 6x^3 + 12x^2 + 27x^2 + 54x
= 6x^3 + 39x^2 + 54x
Answer:
y=4x+1
Step-by-step explanation:
the rate of change is 4/1 which simplifies to 4.
then the y intercept is 1, because if y grows by 4, then it also shrinks by 4. when x is at 0, y is at 1
Hello from MrBillDoesMath!
Answer:
Leftmost graph: x<= -2 or ( minus infinity, -2]
Middle graph: (-5, infinity)
Right graph: (-2, 3)
Discussion:
I
n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.
In graphs ")" means the value is NOT included but "]" (the square bracket) means the value IS included.
