How do you write this equation "at a concert,you purchase 3 T-shirts and a concert program for a total cost of $90.The program cost $15 and the T-shirts all cost the same.Write and solve an equation to find the cost of one T-shirt."

Answers

Answer 1
Input 15 as the initial value and (3, 90) as x and y to get the equation 90=m(3)+15. Isolate m to get m=25. Each shirt costs $25 and the equation that represents the scenario is y=25x+15.

Make t the subject formula w=3t 11

Answers

(w +/- 11)/3 = t
I know this looks confusing with the "+/-" but I can't see the symbol in between the 3t and the 11, so if it's + then subtract from w, and if it's - then add to w. Hope this helps!

Answer:

[tex]t=\sqrt[11]{\frac{w}{3} }[/tex]

Step-by-step explanation:

Hello, I think I can help you with this

Let's remember a few properties of the form x^n

[tex]x^{n} \\x^{m} *x^{n} =x^{m+n}\\\sqrt[n]{x} =x^{\frac{1}{n }}\\(x^{m} )^{n} =x^{m*n}[/tex]

Step 1

Let

[tex]w=3t^{11}\\\frac{w}{3} =\frac{3t^{11} }{3} \\\frac{w}{3} =t^{11}[/tex]

divide each side by 3

Step 2

take each side and take the eleventh root

[tex]\frac{w}{3} =t^{11} \\\sqrt[11]{\frac{w}{3} }=\sqrt[11]{t^{11}}\\\sqrt[11]{\frac{w}{3} } =(t^{11}) ^{\frac{1}{11} }\\ \sqrt[11]{\frac{w}{3} }=t\\t=\sqrt[11]{\frac{w}{3} }[/tex]

You float 2000 feet along a lazy river water ride. The ride takes less than 10 minutes. Give two examples of possible times and speeds.

Answers

200 ft/m or every minute there is 200 ft traveled.

Answer:

The speed can be expressed like less than 200 feet per minutes.The speed would be 222.22 feet per minute or less.

Step-by-step explanation:

We know that the distance traveled is

[tex]d=2000ft[/tex]

The time that took to travel this distance is

[tex]t<10min[/tex]

This means that the time could be 9 minutes, 8 minutes, 7 minutes. It can be a number between 0 and 10.

The speed is defined as

[tex]s=\frac{d}{t}[/tex]

Replacing all values, we have

[tex]s=\frac{2000ft}{10min}= 200 ft/min[/tex]

Therefore, the speed can be expressed like less than 200 feet per minutes.

Another possible example is using a time of 9 minutes

[tex]s=\frac{2000ft}{9min}= 222.22 ft/min[/tex]

In this case, the speed would be 222.22 feet per minute or less. Notice that this time the speed is not "less than", we have to include a equality relation, because we already used a time that's inside the interval of time given by the problem.

A line goes through the point (5,-7) and has a slope m= -3. Write the equation that represents the line (show work).

Answers

Using point slope formula, y- y1 = m(x - x2)
y - -7 = -3( x - 5)
y + 7 = -3(x - 5)

If the answer needs to be in slope intercept form multiply the -3 by x and -5

y + 7 = -3x +15
Subtract 7 from both sides
y = -3x + 8

The equation that represents the line y = -3x + 8

The slope intercept equation is represented as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

m = -3

y = -3x + b

using (5,-7)

-7 = -3(5) + b

-7 = -15 + b

b = -7 + 15

b = 8

Therefore,

y = -3x + 8

The Sunrise Cafe gets tea bags in boxes of l,000. If the cafe charges $1.75 for each cup of tea, and each cup of tea gets one tea bag, how much money does the cafe receive if they use a whole box of 1,000 teabags? Solve with an equation.

If a box of tea bags costs $95, how much money does the cafe actually make after they have used up the box of tea and have paid for it? Solve with an equation.

Answers

Well you would do $1.75 x 1,000. That would be 1,750$.

Then you would take away that 95$ they spent buying the box of tea bags and their total would be 1,750$ - 95$ = 1,655$.

The amount received from using all the 1000 tea bags is $1750.

The amount made is $1670.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of tea bags in one box = 1000

Charge for each cup of tea = $1.75

For each cup of tea use one tea bag.

The total amount using 1000 tea bags.

= 1000 x 1.75

= $1750

Cost of one box of tea bags = $95

The amount made.

= 1750 - 95

= $1670

Thus,

$1750 is received from using all the tea bags.

$1670 profit is made.

Nicholas bought 5 pens for $3 at this rate how much will he spend on 10 pens?

Answers

he will buy 15 pens for $9 he will have $1 left
Okay so, let's analyze the question first.

We're looking for the cost of the 10 pens that Nicholas bought, right? If he bought 5 for $3, how much do you think the 10 pens will cost?

If you multiply 3 by 2, because he'll buy twice as much as he bought the first time, it'll equal 6.

So..

5 pens = $3
10 pens = $6

If he buys 15, 20, or 25 pens, it'll equal..

5 pens = $3
10 pens = $6
15 pens = $9
20 pens = $12
25 pens = $15

We're basically counting off by 3 to know the cost. I hope this helps!

A sticker costs 15 cents and a packet of 8 similar stickers cost $1. Clement buys 37 stickers. What is the least amount of money that Clement spends on stickers

URGENT PLZ HELP

Answers

8 x 4 = 32 stickers (you still need 5) 4 packs x 1.00 = 4.00
plus
.15 x 5 = .75
total $4.75

Clement should buy 4 packets of 8 stickers and 5 individual stickers to minimize cost, spending a total of $4.75.

The student asked how much money Clement will spend on 37 stickers given the individual sticker price and the packet price. We can calculate the least amount of money Clement can spend by determining the number of packets and individual stickers he should buy.

The price of one sticker is $0.15, and a packet of 8 stickers costs $1.00. To get the best value, Clement should buy as many packets as possible. Since 37 is not divisible by 8, the closest multiple of 8 is 32 (which is 8 stickers in 4 packets), so he will buy 4 packets and then 5 additional individual stickers.

The cost of 4 packets is 4 packets times $1.00/packet = $4.00.

The cost of 5 individual stickers is 5 stickers times $0.15/sticker = $0.75.

The least amount Clement will spend on 37 stickers is the total cost of packets plus individual stickers, which is $4.00 + $0.75 = $4.75.

The function f(x)=2x−5 is a linear function. Let g(x) represent f(x) after a horizontal translation 3 units to the right.

What is the equation for g(x)?



Enter the answer in the box.

g(x)=____

Answers

gx= 2x-2

Shall be the new parallel equation

Answer:

The equation for g(x) after a horizontal translation 3 units to the right of f(x) is 2x-11.

Step-by-step explanation:

If y = f(x), then y = f(x-h) gives a horizontal translation which results in a graph that is equivalent to shifting the base graph left or right in the direction of the x-axis.

Given linear function f(x) = 2x−5

g(x) represent f(x) after a horizontal translation 3 units to the right that is

g(x) = 2(x-3)-5

g(x) = 2x-6-5

g(x)= 2x-11

The graph plot below shows the horizontal translation of the function f(x) 3 units to the right.

Thus, the equation for g(x) after a horizontal translation 3 units to the right of f(x) is 2x-11.

How many solutions does this equation have: -9x+1=-9x+1

Answers

Final answer:

The equation -9x+1=-9x+1 has infinitely many solutions.

Explanation:

This equation, -9x+1=-9x+1, is an example of an equation with infinitely many solutions. This means that any value of x will satisfy the equation. To see this, we can simplify the equation:

-9x + 1 = -9x + 1

By subtracting -9x from both sides, we get:

1 = 1

This is a true statement, which means that any value of x is a solution to the equation. Therefore, there are infinitely many solutions to this equation.
