Answer:
The slope of line k is - 4 .
Step-by-step explanation:
The slope of given line p is 1/4
Let the slope of line k which is perpendicular to is m.
When the two line are perpendicular to each other, the product of the slopes is always negative 1.
So, the slope of line k is given by
Step-by-step explanation:
2x - y = 5
-y = 5 - 2x

Six billion six hundred fifty-one million two-hundred ninety-seven thousand.
6,651,297,000 rounded to nearest hundred million = 6,700,000,000
<h2>$2.98</h2>
Step-by-step explanation:
5 bags of chips and 4 jars of dipping sauce cost $21.82. Also, 4 bags of chips and 3 jars of dipping sauce cost $16.86.
This problem can be modeled using linear equations in two variables.
Let 
be the cost of a bag of chip and 
be the cost of a jar of dipping sauce.
The information yields the equations
∴ A jar of dipping sauce costs 
.
Answer:
x = notebooks
y = indexboks
3x+4y=32 ( here is spent all money so I add 32 here )
5x+5y=50
by elemination method
3x+4y=32×5
5x+5y=50×4 ( here I'm going to eliminate y )
15 x+20y= 160
20x+20y= 200
- - = -
____________
-5x = -40
x = - 40 / -5
x = 8
here - × - = + so iam taking positive 8
now substitute the value of x in any equation
3×8+4y = 32
24 + 4y = 32
4y = 32-24
y = 8 / 4
y = 2
CHECKING
SUBSTITUTE BOTH VALUES IN ANY EQUATION
5×8+5×2 = 50
40 + 10 = 50
50 = 50
I SUBSTITUTE IN 2ND EQUATION
