The single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]
Logarithm and indicesGiven the logarithmic expression;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)[/tex]
We are to write it as a single logarithm
Using the product and quotient law of logarithm;
[tex]2(log_38+log_3z)-log_3(3^4-7^2)\\=2(log_38+log_3z)-log_3(\frac{81}{49} )\\=2(log_38z)-log(\frac{81}{9})\\=log_364z^2-log(\frac{81}{9})[/tex]
Simplify the final result to have:
[tex]=log_364z^2-log(\frac{81}{9})\\=log_3(\frac{9(64z^2)}{81} )[/tex]
Hence the single logarithmic form f the expression is [tex]log_3(\frac{9(64z^2)}{81} )[/tex]

Answers
Answer:
Part A
The required inequality is;
y = 50 - 2 × x ≥ 20
Please find attached the graph of the inequality created with Microsoft Excel
Part B
The number of weeks she can withdraw is less than or equal to 15 weeks
Step-by-step explanation:
The given parameters are;
The amount Kate has in her savings account at the beginning of the summer = $50
The least amount she wants to have in the account at the end of the summer = $20
The amount she withdraws each weak from the account = $2
Part A
Let 'x' represent the number of weeks she can withdraw money, we have;
The required inequality that gives the number of weeks she can withdraw money is given as follows
y = 50 - 2 × x
y ≥ 20
Therefore, the inequality is;
y = 50 - 2 × x ≥ 20
The graph of the inequality created with Microsoft Excel is attached
Part B
The number of 'x' weeks she can withdraw is;
50 - 2 × x ≥ 20
- 2 × x ≥ 20 - 50 = -30
x ≤ -30/(-2) = 15
The number of weeks she can withdraw is x ≤ 15 weeks.

Answers
Answer: 700 oranges
Step-by-step explanation: mass of box is reduced first.
Mass of oranges is 60 kg -7.5 kg = 52.5 kg
Mass or oranges is divided by mass of one orange 75 g = 0.075 kg.
52.5 kg/0.075 kg= 700

Find the linear equation whose graph is the straight line with the given properties through ( 1,-8) and (-1,-1)
Answers
Explanation: solving for y=mx+b (linear equation)
m(slope)=y2-y1/x2-x1
(x1= 1, y1=-8),(x2=-1,y2=-1)
M=-1-(-8)/-1-1=7/-2= -7/2
To find the b(y-intercept),use one of the coordinates and plug it into y=mx+b, I will use (x=1,y=-8): -8=-7/2(1)+b
-8/1=-7/2(1)+b/1 -divide the 1 to cancel it and bring it to the other side.
-8+7/2=-7/2+7/2+b -add the 7/2 to cancel it and bring it to the other side.
-9/2=b -b is now isolated and is solved.
So, that’s how you get y=-7/2x-9/2
The equation of a line for the given coordinates is 7x+2y+9=0.
The given coordinates are (1, -8) and (-1, -1).
We need to find the linear equation whose graph is a straight line.
What is the slope of a line?The slope of a line is defined as the change in the y coordinate with respect to the change in the x coordinate of that line. The slope of a line=m=(y2-y1)/(x2-x1).
Now, slope of the line=(-1-(-8))/(-1-2)
=7/(-2)
=-7/2
Now, put m=-7/2 and (-1, -1) in the equation y=mx+c.
So, -1=(-7/2)(-1)+c
⇒-1-7/2=c
⇒c=-9/2
Then the equation of the line=y=-7x/2-9/2
⇒2y=-7x-9
⇒7x+2y+9=0
Therefore, the equation of a line for the given coordinates is 7x+2y+9=0.

y=1/2x+1
Answer:
Slope=1/2, y-intercept=(0,1)
Step-by-step explanation:
Slope is written in the format of Y/X. If you look at the pattern, you'll notice that every time Y goes up 1, X goes up 2.
So, 1/2.
The y-intercept is where the line crosses the y-axis and is therefore when X is equal to 0. Following the pattern, this would be when Y is equal to 1.

Step-by-step explanation:
If linear ratio is a : b , then
area ratio = a² : b²
volume ratio = a³ : b³
Given area ratio = 16 : 9 , then
linear ratio = [tex]\sqrt{16}[/tex] : [tex]\sqrt{9}[/tex] = 4 : 3
volume ratio = 4³ : 3³ = 64 : 27

A consultant for a major computer company receives $3250 per month as a fee no matter how many hours he works. Using x to represent the number of hours the consultant works each month, write a function, f, in symbolic form to represent the total amount the consultant recieves each month.
Answers
Answer:
The function is;
f(x) = $3,250
Step-by-step explanation:
The fixed amount the consultant receives each month = $3,250
The number of hours the consultant works each month = x
Let f(x) represent the function of the total amount the consultant receives each month
Therefore;
The function f(x) = The total amount the consultant receives each month = The fixed amount the consultant receives = $3,250
∴ f(x) = $3,250.
The function 'f' which represents the total amount the consultant receives each month is f(x) = $3,250 (Given that the consultant receives a constant amount each month).

O A. 82.5

Answers
Answer:
A: 82.5
Step-by-step explanation:
Average score of the 4 regular tests = (78 + 72 + 74 + 88)/4 = 78
We are told;
- the regular tests account for 40% of the final grade.
- final exam counts for 20%
- project counts for 10%
- homework counts for 30%
Thus;
weighted mean grade = (40% × 78) + (20% × 79) + (10% × 88) + (30% × 89) = 82.5

Step-by-step explanation:
In a parallelogram, you know that parallel sides are equal in length, therefore, x+4 must equal 5x-24. From there you solve for x.
x+4 = 5x-24
28 = 4x (subtract x from both sides and add 24 to both sides)
7=x (28 divided by 4 is 7).
Answer:
Here you go, please mark brainliest for my effort! Thanks!
Step-by-step explanation:
5x - 24 and x + 4 are equal in length, so set them equal to each other.
5x - 24 = x + 4
Subtract x on both sides.
4x - 24 = 4
Now, add 24 to both sides.
4x = 28
Finally, divide both sides by 4.
x = 7
So the answer is x = 7
