6X + 10 Y = 240
Rewriting this in slope intercept form
10y = -6x+240
y = -6/10x + 240/10
y = -.6x + 24
We know that x and y cannot be less than 0
The y intercept is 24 and the x intercept ( where y=0) is 40
To find the x intercept let y = 0
0 = -.6x + 24
-24 = -.6x
-24/.6 = -.6x/-/6
40 =x
If the budget is reduced by 25%, that means 240 is 25% less or 75% of the original value
75% of 240 = .75*240 or 180
6x+10y = 180
10y = -6x+180
y = -.6x+18
The y intercept is 18 and the x intercept is 30
If the price of x doubles
6 will become 12
12x+10y = 240
10y = -12x + 240
y = -1.2x +24
The y intercept is 24 and the x intercept is 20
If the price of y falls to 8
6x+8y = 240
8y = -6x+240
y = -6/8x + 240/8
y = -.75x + 30
The y intercept is 30 and the x intercept is 40
<h3><u>Explanation</u></h3>
- Given expression
- Factor the expression by using common factor.
We csn pull out 3x² out of the expression.
We simply pull out the x-term with lowest degree and 3 out of the expression. If another expression cannot be factored after first factoring then that's the final answer.
- The expression can still be factored. Factor the expression by using two brackets.
- New factored form
