If you would like to simplify <span>5 + 2{x - 4[3x + 7(2 - x)]}, you can do this using the following steps:
</span>
5 + 2{x - 4[3x + 7(2 - x)]} = 5 + 2{x - 4[3x + 7 * 2 - 7x]} = 5 + 2{x - 4[-4x + 14]} = 5 + 2{x - 4 * (-4)x + (-4) * 14} = 5 + 2{x + 16x - 56} = <span>5 + 2x + 2 * 16x - 56 * 2 = 5 + 2x + 32x - 112 = 34x - 107
The correct result would be </span><span>34x - 107.</span>
The reflection line is located at y = -x
For point J, x is -2, so y = -(-2), which equals 2.
When it is a reflection across Y, the X values remain the same.
Find the distance of the Y point to the reflection line,
The distance from -1 to 2 is 3 units.
The new point needs to be the same distance from the reflection line.
2 + 3 units = 5.
Point J' would be (-2,5)
When the x-value has increased by 1 unit, the y-value has multiplied by 3, so we expect a function of the form (something)×(3^x). The last choice has that.
... f(x) = 4(3)^x

You can always evaluate the offered choices at the given points to see which of them works. The second point (2, 36) will tell you the fastest.
4·3^-2 = 4/9 ≠ 36 . . . . . you can tell at this point you don't want -x as the exponent
3·4^-2 = 3/16 ≠ 36
3·4^2 = 48 ≠ 36
4·3^2 = 36 = 36 . . . . this is the one you want
If the first expression reads x(cube) • x(cube) • x(cube) and x(cube • cube <span>• cube), then the answer is no. They are not equal.
</span>
x(cube) • x(cube) <span>• x(cube) will be equivalent to x(to the 9th power) while </span>x(cube • cube <span>• cube) will be equivalent to x( to the 27th power). </span><span>
