3x-18 is less than -90
First, you add 18 to both sides of the inequality (getting 3x is less than -72). Then you divide by 3 on both sides giving you your answer x is less than -24

X is greater than 36. to find this you substraction 18 from both sides which leaves you with -3x<-108 then you divide both sides by -3 and when working with inequalities you have to flip the sign whenever you multiply or divide by a negative. so you end up with x>36

Answer:

The simplified fraction of the expression $\frac{5^2\times 5^{-4}}{5}$ will be:

$\frac{5^2\times \:5^{-4}}{5}=\frac{1}{125}$

Step-by-step explanation:

Given the expression

$\frac{5^2\times 5^{-4}}{5}$

Steps to solve the expression

$\frac{5^2\times 5^{-4}}{5}=\frac{5^{-2}}{5}$ ∵ $5^2\times \:5^{-4}=5^{2-4}$

$=\frac{1}{5^3}$

$=\frac{1}{125}$ ∵ $5^3=125$

Therefore, the simplified fraction of the expression $\frac{5^2\times 5^{-4}}{5}$ will be:

$\frac{5^2\times \:5^{-4}}{5}=\frac{1}{125}$

What describes the transformation of g(x)=3(2)-x from the parent function f(x)=2x

Mama L [17]

Answer:

Reflect across the y-axis, stretch the graph vertically by a factor of 3

Step-by-step explanation:

The question has certain errors, in fact the functions are the following:

g (x) = 3 * (2) ^ - x

f (x) = 2 ^ x

The transformation that we can do to obtain the translated graph, Are given in 2 steps, which are the following:

1. When x is replaced by -x, then it reflects the graph on the y axis.

2. 3 multiplies with the function, it means that it stretches the main function vertically in 3 units.

So to summarize it would be: Reflect across the y-axis, stretch the graph vertically by a factor of 3

A square has side length of 8 in. If the area is multiplied by 36, what happens to the side length? HELP PLEASE!!

GaryK [48]

Answer:

The side length is multiplied by 6.

Step-by-step explanation:

The area of a square is A = s². Suppose the side is 8 inches. This means the area is A = 8² = 64.

If you were to multiply by 36, then it becomes 64*36 = 2,304. Since squaring gave the area, it's side length would be found using the reverse operation a square root. Take the square root of 2,304.

√2304 = 48

The side length changed from 8 to 48 which is a scale factor of 6. This means 8 * 6 = 48.
