Answer: 2(x + 2) + 2 = 2(x + 3) + 1

Steps:

2x + 6 = 2x + 7

<em>Subtract 6 from both sides</em>

2x + 6 - 6 = 2x + 7 - 6

<em>Simplify</em>

2x = 2x + 1

<em>Subtract 2x from both sides</em>

2x - 2x = 2x + 1 - 2x

<em>Simplify</em>

0 = 1

The sides are not equal.

Answer:

Ok so first you want to distribute the -1 in front of the 3x^2-7x+1

Which turns the problem into

X^2+5x-6 -3x^2+7x-1

Then just combine like terms

-2x^2+12x-7

Also ^ followed by the number is the exponent

100 POINTS IF YOU ANSWER CORRECTLY Rotate these coordinates 180 around the origin and then translate 6 units to the left.
snow_tiger [21]
Original Coordinates: (-2, -8) (-6, -8) (-11, -1) (-7, -3)

A 180 degree rotation around the origin flips the signs of x and y, so you get:

(2, 8) (6, 8) (11, 1) (7, 3)

Then a translation to the left 6 units just subtracts 6 from all the x values:

(-4, 8) (0, 8) (5, 1) (1, 3)

Those are your points! Hope this helped!

Solve the following system by any method. –8x – 8y = 0 –8x + 2y = –20
madam [21]
This one is simple since we already have the two x variables.equal. All we have to do is subtract the equations from one another to get the answer.
So i will subtract the left side by the other left side and the right side by the other right side

-8x - 8y -(-8x + 2y) = 0 -(-20)

distribute negative sign

-8x - 8y + 8x - 2y = 0 + 20

do the math
- 10y = 20
Y = -2

plug t into an equation
-8x -8 (-2) = 0

-8x + 16 = 0
-8x = -16
x = 2

Please help....................
Aleksandr-060686 [28]

Answer:

x = 0, 1

Step-by-step explanation:

f(x) = g(x)

0.25^x = -0.75x + 1

Move all terms to the left side and set equal to zero

0.25^x +0.75x -1 = 0

slove for x and you'll get x = 0, 1
