Answer:
a=54
Step-by-step explanation:
Because the problem gives you the value of b simply plug it in the equation a=12b. The new equation should look like this when plugged in: a=12(4.5). Now multiply 12*4.5=54. The new equation would then become a=54
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

Have a good day :P :P
Answer:
f(-2) = -6
Step-by-step explanation:
In the expression, to get f(-2);
we simply substitute the value of x with -2
We have this as;
f(-2) = -4(-2)^2 + 10
f(-2) = -4(4) + 10
f(-2) = -16 + 10
f(-2) = -6
