Answer:

b = a + 4

Step-by-step explanation:

I just plugged in a to the equation. Heres my work:

b = 4 + 4 , b = 8

b = 8 + 4, b = 12

b = 12 + 4, b = 16

b = 16 + 4, b = 20

Answer:

x=81 or 1/3

Step-by-step explanation:

$x^\log_3(x)} =81x^3\\\log_3(x^{\log_3(x)})=\log_3(81x^3)\\\(\log_3x)(\log_3x)=\log_381+\log_3x^3\\(\log_3x)^2=3\log_3x^+4\\\\Let u=\log_3x\\\\u^2-3u-4=0\\(u-4)(u+1)=0\\u=4 \\4=\log_3x\\x=3^4=81\\\\u=-1\\-1=\log_3x\\x=3^{-1}=1/3$

What are the co-ordinance of point Q

dimulka [17.4K]

Answer:

(6,3), last option

Step-by-step explanation:

Symmetry To A vertical line

If the point Q (unknown) is symmetric to point P(2,3) with respect to x=4, it means it's located at the same distance to the line as P while keeping the same y-coordinate.

The point P has a distance of 4-2=2 units with respect to x=4. Q must have its x coordinate equal to 4+2=6, and keeping the y-coordinate equal to 3

The coordinates of Q are (6,3), last option
