Answer:

hope ithelps :)

Step-by-step explanation:

1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.

And horizontal lines go through the y-axis and have equations of y= a #

2)the point on the vertical line is (4,-5), it has a y-value of -5

****Every y value on a horizontal line will be the same

so the equation for a perpendicular line would be y= -5

The equation for the cost of the television without remote control is  x = 649 + 125 and its solution is $774.

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now it is given that,

Cost of television with remote control = $649

It is also given that this amount is $125 more than the cost without remote control.

Suppose x be the cost of television without remote control.

Thus, x = 649 + 125

⇒ x = 774

Thus, the equation for the cost of the television without remote control is  x = 649 + 125 and its solution is $774.

Answer:

(2 n)/3-2/3 = n/6+4/3

(2 n)/3-2/3 = (2 n-2)/3:

(2 n-2)/3 = n/6+4/3

Put each term in n/6+4/3 over the common denominator 6: n/6+4/3  =  n/6+8/6:

(2 n-2)/3 = n/6+8/6

n/6+8/6 = (n+8)/6:

(2 n-2)/3 = (n+8)/6

Multiply both sides by 6:

(6 (2 n-2))/3 = (6 (n+8))/6

6/3 = (3×2)/3 = 2:

2 (2 n-2) = (6 (n+8))/6

(6 (n+8))/6 = 6/6×(n+8) = n+8:

2 (2 n-2) = n+8

Expand out terms of the left hand side:

4 n-4 = n+8

Subtract n from both sides:

(4 n-n)-4 = (n-n)+8

4 n-n = 3 n:

3 n-4 = (n-n)+8

n-n = 0:

3 n-4 = 8

Add 4 to both sides:

3 n+(4-4) = 8+4

4-4 = 0:

3 n = 8+4

8+4 = 12:

3 n = 12

Divide both sides of 3 n = 12 by 3:

(3 n)/3 = 12/3

3/3 = 1:

n = 12/3

The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

Answer:

1.65 + 0.09s

Step-by-step explanation:

Given that :

Cost of speaker = $22

Cost per song = $1.25

Sales tax rate = 7.5%

Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)

Expanding the expression :

0.075(22 + 1.25s)

(0.075 * 22) + (0.075 * 1.25s)

1.65 + 0.09375s

Rounding to the nearest hundredth :

Sales tax on entire purchase :

1.65 + 0.09s

Step-by-step explanation:

Use the y=mx+b reference

the b refers to the y intercept which in your case is -4

so on the graph you would put -4 on the y line so at (0,-4)

Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1

The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.

To graph the equation y = 1.2x - 4:

The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.

Answer: f(x)= -2x+1

Step-by-step explanation:

The expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

We have,

[tex]\frac{64^x}{4^{5x-1}}[/tex]

So,

Now, to rewrite in form of [tex]4^{f(x)}[/tex],

So,

Rewrite the given expression in the form of 4,

i.e.

[tex]\frac{64^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3)^x}{4^{5x-1}}[/tex]

[tex]=\frac{(4^3x)}{4^{5x-1}}[/tex]

NOw,

Using Exponent rule,

We get,

[tex]=4^{3x-(5x-1)}=4^{3x-5x+1}[/tex]

On solving we get,

[tex]=4^{-2x+1}[/tex]

So,

[tex]4^{f(x)}=4^{-2x+1}[/tex]

Hence, we can say that the expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Answer:

Question 1-- $250+$2(100)= 350 dollars

Question 2-- $250+$2(150)= 400 dollars

Step-by-step explanation:

To calculate the band's total pay for x number of tickets sold, we can use the following expression Total pay [tex]= $250 + ($2 * x)[/tex] For example, if the band sells 100 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 100) = $250 + $200 = $450[/tex]

Therefore, the band would make $450 for selling 100 tickets. Similarly, if the band sells 150 tickets, the calculation would be: Total pay [tex]= $250 + ($2 * 150) = $250 + $300 = $550[/tex]

Hence, the band would make $[tex]550[/tex]for selling 150 tickets. This expression takes into account the fixed payment of $[tex]250[/tex] for the band's performance and an additional $2 for each ticket sold. By multiplying the number of tickets sold (x) by $2 and adding it to the fixed payment, we can calculate the band's total earnings.
