Answer:
<h3>40 inches squared</h3>
Step-by-step explanation:
2+2=4
5+5=10
10x4=40
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
2x + y =7 (1)
3x-y=8 (2)
(1) + (2)
5x = 15
x = 3
Answer:
<h2><em><u>9</u></em></h2>
Step-by-step explanation:


= <em><u>9 (Ans)</u></em>
3x - 8 = -2
3x = -2 + 8
3x = 6
x = 6/3
x = 2
so the value of x - 6 = 2 - 6 = -4 <==
