Answer:

$60

Step-by-step explanation:

So from the question, we need to find the fixed amount for the tv's. So we have to make an equation, and don't forget to add the extended warranties:

11(x + 25) = 935

x will represent a tv, and the 25 is the extended warranty for a tv, since the questions states 11 tv's with warranties is 935, the equation will look like that. Now lets slove:

11(x + 25) = 935

multiply

11x + 275 = 935

subtract 275 from both sides

11x = 660

divide both sides by 11

x = 60, each tv is $60

Answer:

0.205 (rounded)

Step-by-step explanation:

Perform long division by multiplying the numbers by 1000 to remove the decimals and then solving. Or you could have just used a calculator lol. So I did like 5 digits of it, and you could just round to 0.205, I wouldn't go too far with the decimals even though it is a terminating decimal I believe.

Answer:

[tex]f(x) = 5x - 7 \\ change = f(7) - f( - 3) \\ = ((5)(7) - 7) - ((5)( - 3) - 7) \\ = (35 - 7) - ( - 15 - 7) \\ = (28) - ( - 22) \\ = 50 \\ average \: change = \frac{change}{2} \\ = \frac{50}{2} \\ = 25[/tex]

The rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.

A function f(x) = 5x - 7 is given which changes from x = -3 to x = 7.

We have to find out the average rate of change for the given function.

What is the average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] ?

The average rate of change of function from [tex]x_{1}[/tex] to [tex]x_{2}[/tex] can be given by a formula which is [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex].

As per the question ;

The function is f(x) = 5x - 7

So,

At x = -3

f(x) = 5 × -3 - 7

f(x) = -15 - 7

f(x) = -22

At x = 7

f(x) = 5 × 7 - 7

f(x) = 35 - 7

f(x) = 28

Let's use the formula to find average rate of change of function ;

i.e.,

=  [tex]\frac{f(x_{1})-f(x_{2})}{x_{1} - x_{2}}[/tex]

= [tex]\frac{(28)-(-22)}{7-(-3)}[/tex]

= [tex]\frac{28+22}{7+3}[/tex]

= [tex]\frac{50}{10}[/tex]

= 5

Thus , the rate of change of function f(x) = 5x - 7 from x = -3 to x = 7 will be equal to 5.

Answer:

Zac will finish, Pam won’t

Step-by-step explanation:

Let’s have the individual reading speeds

The individual reading speeds are the number of pages divided by hours taken

For Pam; 126/3 = 42 pages per hour

For Zac; 180/4 = 45 pages per hour

In five hours, Zac would read; 45 * 5 = 225 pages

In five hours, Pam would read 42 * 5 = 210 pages

A) $1.60

B) $13.60

C) 3 1/4 lb

Step-by-step explanation:

What we know:

A farmer uses the equation c = 1.6p to calculate the total cost, c, for p pounds of apples.

A) 1 pound would cost $1.60, as that is the unit rate.

B) 8.5 * 1.6

8.5 + (0.6 * 8.5)

8.5 + 5.1 = $13.60 for 8 1/2 lbs of apples.

C) 5.2/1.6

52/16

13/4 = 3 1/4 lbs of apple for $5.20

Answer:

(-1/4, 2)

Step-by-step explanation:

Substitute the given information into the equation and solve for y.

 3y +4(-1/4) = 5

 3y -1 = 5 . . . . . . simplify

 3y = 6 . . . . . . . . add 1

 y = 2 . . . . . . . . . divide by 3

(The other person who said -5 is incorrect and he gave no explination)

Answer:

Step-by-step explanation:

slope-intercept form of equation:  y = mx + b

where m is slope and b is y-intercept

If line y=ax+b passes through point (x₀,y₀) that means

that the equation y₀=ax₀+b is true

(2, 5)    ⇒   x=2,   y=5

m = 5

So:

              5 = 5×2 + b

               5 = 10 + b

               b = -5

Therefore equation in  slope-intercept form:

                                                                      y = 5x + (-5)

                                                                      y = 5x - 5                          

The equation of the line in slope-intercept form is y = 5x - 5.

Given that the slope of the line is 5 and it passes through the point (2, 5), we can use the point-slope form of a linear equation to find the equation of the line.

The point-slope form is given by:

y - y1 = m(x - x1),

where (x1, y1) is the given point and m is the slope.

Substituting the values, we have:

y - 5 = 5(x - 2).

Now, let's simplify this equation:

y - 5 = 5x - 10.

Next, let's isolate y:

y = 5x - 10 + 5.

Simplifying further:

y = 5x - 5.

So, the equation of the line in slope-intercept form is y = 5x - 5.

Step-by-step explanation:

Your question wasn't well written but I saw an identical question so let me help out.

a. Jada has a meal in a restaurant she adds up the prices listed on the menu for everything they ordered and gets a subtotal of $42.00. When the check comes, it says they also need to pay $3.99 in sales tax. what percentage of the subtotal is the sales tax?

b. They actually pay $52.99. The additional $7 is a tip for the server. What percentage of the subtotal is the tip?

a. Subtotal = $42.00

Tax = $3.99

Percentage of subtotal that is sales tax will be:

= Sales tax/Subtotal × 100

= 3.99/42.00 × 100

= 9.5%

b. Tip = $7

Sub total = $42

The percentage of the subtotal that is the tip will be:

= Tip/Sub total × 100

= 7/42 × 100

= 16.67%
