3^(4x-5) = (1/27)^(2x+10) show your work
Answer:
3^4x-5=1/27^2x+10
We move all terms to the left:
3^4x-5-(1/27^2x+10)=0
Domain of the equation: 27^2x+10)!=0
x∈R
We get rid of parentheses
3^4x-1/27^2x-10-5=0
We multiply all the terms by the denominator
3^4x*27^2x-10*27^2x-5*27^2x-1=0
Wy multiply elements
81x^6-270x^2-135x^2-1=0

Monica swims the 200, 400, and 1,000 meter freestyle swimming events. At the last swimming meet she swam the 200m in 1 minute 4 seconds, 400m in 2 minutes 31 seconds, and the 1,000 meter in 7 minutes 11 seconds. What were her average speeds in all these events (meters/second)?
Answer:
a) 200 meters = 3.125 meters/seconds
b) 400 meters = 2.649 meters per second
c ) 1000 meters = 2.320 meters per second
Step-by-step explanation:
The formula for Average speed = Distance/ Time
Monica swims the 200, 400, and 1,000 meter freestyle swimming events.
We are to calculate: average speeds in all these events (meters/second).
At the last swimming meet she swam
For the 200m
Time 1 minute 4 seconds
60 seconds = 1 minutes
Hence, Time = 60 + 4 = 64 seconds.
Average speed = 200m/64 seconds
= 3.125 meters/seconds
For 400m
Time = 2 minutes 31 seconds
1 minute = 60 seconds
2 minutes = 60 × 2 = 120 seconds
Total time = 120 + 31 seconds = 151 seconds
Hence, Speed = 400m/151 seconds
= 2.649 meters per second
For 1,000 meter
Total time = 7 minutes 11 seconds.
1 minute = 60 seconds
7 minutes = 60 × 7 = 420 seconds
Total time = 420 + 11 seconds = 431 seconds
Hence, Speed = 1000m/431 seconds
= 2.3201856148 meters per second
Approximately = 2.320 meters per second
Therefore her speed were
a) 200 meters = 3.125 meters/seconds
b) 400 meters = 2.649 meters per second
c ) 1000 meters = 2.320 meters per second
Answer:
3.125m/s
2.469 m/s
2.320 m/s
Step-by-step explanation:
Average speed = total distance / total time
60 seconds = 1 minute
Converting minute into second = (1 x 60) + 4 = 64 seconds
(2 x 60) + 31 = 151 seconds
(7 x 60) + 11 = 431 seconds
Average speed = 200 meters / 64 seconds = 3.125m/s
Average speed = 400 meters / 151 seconds = 2.469 m/s
Average speed = 1000 meters / 431 seconds = 2.320 m/s

7x + 10 = 3x + 13
Answer:
x=3/4Step-by-step explanation:
Let's solve your equation step-by-step.
7x+10=3x+13
Step 1: Subtract 3x from both sides.
7x+10−3x=3x+13−3x
4x+10=13
Step 2: Subtract 10 from both sides.
4x+10−10=13−10
4x=3
Step 3: Divide both sides by 4.
4x/4=3/4
x=3/4

Answer:
the thrid one
Step-by-step explanation:
The table that shows a function that is decreasing only over the interval (-1, oo) is table 3
For a table to show a decreasing interval, then the table values must reduce as the x value increase
The interval (-1, oo) means that, -1 is exclusive of the x values.
So, we start from x > -1
The first table shows an increasing function for x > -1
The second table shows an increasing and decreasing function for x > -1
The third table shows a decreasing function for x > -1
The last table shows a decreasing function for x > -1 but increases at other values
Hence, the table that shows a function that is decreasing only over the interval (-1, oo) is table 3

First equation: t=b-4
Second equation: b+t=348
Since t is in terms of b from the first equation, this expression can be substituted into the second equation where t appears. Write an equation that shows this substitution.
Type the equation:
Answer:
equation: b+(b-4)=348

The scale on a map is 4 cm = 25 miles. Dave measures the distance to the next town at 9 cm. How many miles away is the next town?
Answer:
58.333....
Step-by-step explanation:
8cm=50
1cm so 25/3
8.3333333333
Answer:
56.25 or 56 1/4
Step-by-step explanation:
If 4 cm is equal to 25 miles then we can divide 25 by 4 to see how many miles is in 1 cm.
25 divided by 4 is 6.25 or 6 1/4
Therefor 1 cm is equal to 6.25 miles.
Now we multiply 9 by 6.25 to get 56.25

Answer:
I think a is 9 cause 9+ 8 is 17 ??
The value of A,B,C,D and E will be 23,25,7 15 ,and 9 respectively.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
If we make the sum of each side diagonally then the sum should be 48.
So,
D+ 16 + 17 = 48
D = 15
And
15 + B + 8 = 48
B = 25
And,
25 + 16 + C = 48
C = 7
And,
8 + A + 17 = 48
A = 23
And,
15 + E + 24 = 48
E = 9
Hence "The value of A,B,C,D and E will be 23,25,7 15 ,and 9 respectively".

A line perpendicular to y=2/5x+1
Answer:
y = -⁵/₂x + bStep-by-step explanation:
y=m₁x+b₁ ⊥ y=m₂x+b₂ ⇔ m₁×m₂ = -1
{Two lines are perpendicular if the product of theirs slopes is equal -1}
y = ²/₅x + 1 ⇒ m₁ = ²/₅
²/₅m₂ = -1 ⇒ m₂ = -⁵/₂
So, any line with slope m = -⁵/₂ will be perpendicular to y = ²/₅x + 1

Answer:
a) [tex]f(2) = 5[/tex], b) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex], c) [tex]f^{-1} (7) = 3[/tex]
Step-by-step explanation:
a) We evaluate the function at [tex]x = 2[/tex]:
[tex]f(2) = 2\cdot (2) + 1[/tex]
[tex]f(2) = 4+1[/tex]
[tex]f(2) = 5[/tex]
b) First, we determine the inverse of the function by algebraic means:
1) [tex]y = 2\cdot x + 1[/tex] Given
2) [tex]y +(-1) = 2\cdot x + [1+(-1)][/tex] Compatibility with addition/Associative property
3) [tex]y + (-1) =2\cdot x[/tex] Existence of additive inverse/Modulative property
4) [tex]2^{-1}\cdot [y+(-1)] = (2\cdot 2^{-1})\cdot x[/tex] Compatibility with multiplication/Commutative and associative properties
5) [tex][y+(-1)]\cdot 2^{-1} = x[/tex] Existence of multiplicative inverse/Modulative and commutative properties
6) [tex]x = [y+(-1)]\cdot 2^{-1}[/tex] Symmetry property of equality
7) [tex]x = \frac{y-1}{2}[/tex] Definitions of subtraction and division
8) [tex]f^{-1} (x) = \frac{x-1}{2}[/tex] [tex]x = f_{-1} (x)[/tex]/[tex]y = x[/tex]/Result
c) Now we evaluate the expression obtained on b) at the given number:
[tex]f^{-1} (7) = \frac{7-1}{2}[/tex]
[tex]f^{-1} (7) = 3[/tex]

Answer: 18
Step-by-step explanation:
hi, can you please solve that ?
Answer:
A.
Step-by-step explanation:
You need to solve for p on both inequalities.
4 ≤ p - 8
12 ≤ p
p - 14 ≤ 2
p ≤ 16
This means that p is greater than or equal to 12 but less than or equal to 16.
12 ≤ p ≤ 16
Therefore, the answer is A.
