13x-6y=22 x=y+6 find x and y
Vesna [10]
13x - 6y = 22
x - y = 6
6(x-y) = 6*6
6x - 6y = 36
subtract both the equations
13x - 6x -6y + 6y = -14
7x = -14
x = -2
13*-2 -6y=22
-26 -6y=22
-6y = 48
y = -8
answer: x = -2
y = -8

What is the equation of the line that passes through the point (9, 6) and is perpendicular to the line y = 3x - 5?
Ilia_Sergeevich [38]

Answer:

Step-by-step explanation:

y = 3x - 5

m₁ = 3

The required line is perpendicular to y = 3x - 5. Let the required line's slope be m₂

m₂ = -1/m₁

m₂ = -1/3

Point (9,6)

Equation of line: y - y₁ = m(x - x₁)

y - 6 = (-1/3)(x - 9)

y-6=\frac{-1}{3})x+\frac{1}{3}*9\\\\y-6=\frac{-1}{3}x+3\\\\y=\frac{-1}{3}x+3+6\\\\y=\frac{-1}{3}x+9\\

8. You have 160 meters of fencing to enclose a rectangular pen for your dog. To provide sufficient running
kolbaska11 [484]

Perimeter is the sum of the length of the sides used to make the given figure. The length and the width of the rectangle are 60 meters and 20 meters, respectively.

<h3>What is the perimeter?</h3>

Perimeter is the sum of the length of the sides used to make the given figure.

Let the width of the rectangle be represented by x.

Given that the pen should be three times as long as it is width. Therefore, the dimensions of the rectangle can be written as,

Width of the rectangle = x

Length of the rectangle = 3x

Also, it is given that the perimeter of the rectangle should be equal to 160 meters, therefore, we can write,

Perimeter = 2(Length + Width)

160 = 2(3x + x)

160 = 2(4x)

160 = 8x

x = 160/8

x = 20 meters

Now, the dimensions of the rectangle can be written as,

Length = 3x = 3 × 20 meters = 60 meters

Width = x = 20 meters

Hence, the length and the width of the rectangle are 60 meters and 20 meters, respectively.

What is the rate of change?<br> I”lll give u Branlyest if you get it right
Luda [366]

Answer: In 1 minute, the temperature goes up 50 degrees.

Step-by-step explanation:

This is the rate of change in this graph because 50 degrees is in 1 minute, so we divide 50 by 1. We get 50, so we add 50 to 50 and 100, and so forth. The answer is In 1 minute, the temperature goes up 50 degrees.

Hope this helps!
