Answer:

b = 1/3

Step-by-step explanation:

Here, we want to solve for the value of b

From the question, we have that;

4^(3b-3) = 1/16

4^(3b-3) = 16^-1

4^(3b-3) = 4^2(-1)

4^(3b-3) = 4^-2

Since base are equal, equate the powers

3b - 3 = -2

3b = -2 + 3

3b = 1

b = 1/3

Alex has 3 times as many pets as Roman. If they have 24 altogether ,how many do they have ?

Viefleur [7K]

A= 3R
R = A/3
24= A + R
24= 3R + R
24 = 4R
6= R
A= 18

Roman = 6
Alex = 18

6+18 = 24

If s(x)=x-7 and t(x)= 4^2-x+3 what is equivalent to (t•s)(x)

Rzqust [24]

Hello!

If s(x) = x - 7 and t(x) = 4² - x + 3, find (t · s)(x) is also known as a composite function. (t · s)(x) is read as "t is composed of s", or "the composition of t and s".

(t · s)(x) = 4² -(x - 7) + 3

(t · s)(x) = 16 - x + 7 + 3

(t · s)(x) = -x + 16 + 7 + 3

(t · s)(x) = -x + 26

Therefore, (t · s)(x) = -x + 26.

Given: LM ∥ KN LP ⊥ KN , KL = MN KN = 30, LM = 20 m∠KLM=126° Find: LP

Ronch [10]

An angle is produced at the point where two or more lines meet. Thus the value of LP required in the question is approximately 14.

Two lines are said to be perpendicular when a measure of the angle between them is a right angle. While parallel lines are lines that do not meet even when extended to infinity.

From the question, let the length of LP be represented by x.

Thus, from the given question, it can be deduced that;

LM ≅ PN = 20

KP = KN - PN

= 30 - 20

KP = 10

LP = x

Also,

<MLP is a right angle, so that;

< KLP = < KLM - <PLM

= 126 - 90

<KLP = $36^{o}$
