the perimeter of a rectangle is 20 units. The length of the rectangle is the distance from(-2,6) to (5,6) What is the width in u

DIA [1.3K]

Answer:

3 units.

Step-by-step explanation:

We can calculate the length, since it only moves on the "x" axis, since on the "y" axis, it remains the same.

We know that between -2 to 5, there are 7 units. 2 + 5 = 7.

Therefore this would be the length.

We know that the perimeter is equal to:

p = 2 * w + 2 * l

P = 20

20 = 2 * w + 2 * 7

2 * w = 20 - 14

w = 6/2

w = 3

therefore, the width value is 3 units.

What is the value of x? (1/3)^x-2 =(1/3)^2

Mice21 [21]

Answer:

Step-by-step explanation:

Hi there,

To solve this, we want to isolate x either using logs or exponent rules. For this, I chose exponent rules.

First, divide both sides of the equation by (1/3)² :

$\frac{((\frac{1}{3} )^{x-2} )}{(\frac{1}{3} )^{2} } = \frac{(\frac{1}{3} )^{2} }{(\frac{1}{3} )^{2} } \\$

The right-hand side is reduced to 1. The left-hand side contains values that have the same base, so we can use this exponent rule:

$\frac{x^{a} }{x^{b} } =x^{a-b}$ Apply this:

$(\frac{1}{3})^{x-2-2}=(\frac{1}{3})^{x-4}=1$ Now, we are left with:

$(\frac{1}{3})^{x-4}=1$

Conceptually, you just have to think: what exponent can make a base equal to 1?

This is based on the following exponent rule:

$x^{0} =1$

So, all we have to do is set (x-4) = 0!

$x-4=0\\x=4$

Thus, the value of x is 4.

PLEASE HELP WITH 1-3 ILL MARK U THE BRAINLIEST

sammy [17]

Answer:

1:A(-6,-1) B(-14,0) C(-11,4)

2:D(6,-3) E(2,-3) F(3, -4.5) G(5, -4.5)

3:H(-4,1) I(-4, 6) J(0,6) K(0,1)

Step-by-step explanation:

Before we begin, lets define the transformations:

(x, y)

T(a, b) = (x+a, y +b)

Rxaxis = (x, -y)

Ryaxis = (-x, y)

r(180, 0) = (-x, -y)

D.5(1/2x, 1/2y)

R(-90, O) = (-y, x)

1. T. A(6,-1) B(14,0) C(11,4)

Rx. A(6, 1) B(14,0) C(11,-4)

r180 A(-6,-1) B(-14,0) C(-11,4)

2. Rx D(-12,-6) E(-4,-6) F(-6, -9) G(-10, -9)

Ry D(12,-6) E(4,-6) F(6, -9) G(10, -9)

D.5 D(6,-3) E(2,-3) F(3, -4.5) G(5, -4.5)

3. Rx=1 H(-1,2) I(4, 2) J(4,-2) K(-1,-2)

T H(1,4) I(6, 4) J(6,0) K(1,0)

r-90 H(-4,1) I(-4, 6) J(0,6) K(0,1)
