Let x = Snicker Bars
Let y = Wrapping paper
Therefore, solve as simultaneous equation:
16x + 4y = 132
20x + 6y = 190
Solve for y:
16x + 4y = 132
x = 132 - 4y/16
Substitute value of x into 20x + 6y = 190:
20(132 - 4y/16) + 6y = 190
2640 - 80y/16 + 6y = 190
2640 - 80y = 16(190 - 6y)
2640 - 80y = 3040 - 96y
96y - 80y = 3040 -2640
16y = 400
y = 400/16
y = 25
Substitute value of y = 25 in x = 132 - 4y/16 to find x:
x = 132 - 4(25)/16
x = 2
Therefore, the prices per Snickers snack bars is 2.
Answer:
Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>
Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=>
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
Slope of line
m= (y2-y1)/(x2-x1)
=(-4--6)/(6--2)
=2/8
=1/4
Line in two point form
(y-y1)=m(x-x1)
y--2=(1/4)(x-6)
y+2=(1/4)(x-6)
simplify
4(y+2)=x-6 =>
x-4y-14=0
Alternatively, use the slope intercept form:
y--2=(1/4)(x-6) =>
y=(1/4)x - 3/2-2 =>
y=(1/4)x -7/2
