Answer:
D
Step-by-step explanation:
f(x) * g(x)= (3x^2-4x-5)(11x-3)
33x^3-44x^2-55x-9x^2+12x+15
33x^3-53x^2-43x+15
Speed is inversely propportionalthe time.
Constant equal to 5.
2x + 3y = 1470
3y = -2x + 1470
y = -2/3x + 490 <== slope intercept form
=================
y = -2/3x + 490
slope = -2/3
y int = (0,490)
=================
description of graphing : Plot ur point at (0,490). Since the slope is -2/3, starting at (0,490)...go down 2 and to the right 3,then down 2 and to the right 3 and you will eventually cross the x axis at the x intercept.
The x intercept can be found by subbing in 0 for y and solving for x
y = -2/3x + 490
0 = -2/3x + 490
2/3x = 490
x = 490 * 3/2
x = 1470/2 = 735...so ur x intercept is (735,0)
therefore, your line will cross the x axis at (735,0)
========================
function notation is : f(x) = -2/3x + 490
========================
suppose his profit is 1593....
2x + 3y = 1593
3y = -2x + 1593
y = -2/3x + 531
the graphs for the two months :
similarities : they both have the same slope of -2/3
differences : they have different x and y intercepts
By the way, these are parallel lines
===================
sorry about the last one....can't see the 3rd month graph
Answer:
9+(-8)
Step-by-step explanation:
8-(-9) is subtraction
9+8 would not give you a difference
8+(-9) would give you a negative number
so 9+(-8) is the right answer
