y = -3x - 2
Step-by-step explanation:
Equation of a line passing through [tex](x_1,y_1)[/tex] and slope m is,
[tex]y-y_1=m(x-x_1)[/tex]
Slope of a line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line passing through (0, -2) and (1, -5) will be,
Slope = [tex]\frac{-2+5}{0-1}[/tex]
m = - 3
Therefore, equation of the line passing through (0, -2) and slope = -3 will be,
y + 2 = -3(x - 0)
y + 2 = -3x
y = -3x - 2
Hey Siri Timothy nvested 12,000 in an account that pays 4% annual simplest interest .timothy will not make any additional deposits or withdrawals . How much interest will Timothy earn on his investment at the end of 4 years
Answer: Timothy will have $1,920 at the end of 4 years.
Step-by-step explanation: Remember, I=prt. So multiply 12,000x0.04x4. The final answer is $1,920.
Answer:
$1920
Step-by-step explanation:
He starts with 12,000 dollars. If he makes 4 percent of that, he is making 480 dollars every year. So you know how much he is making every year, you need to know what he is making in 4 years. 480 * 4 = 1920

[tex]\frac{3}{4} - \frac{2}{9} + \frac{3}{2}[/tex]
Answer:
[tex]\frac{73}{36}[/tex]
Step-by-step explanation:
[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]
1. Convert all the fractions to a common denominator.
For this problem, the common denominator will be 36
[tex]\frac{3}{4}[/tex] * 9 = [tex]\frac{27}{36}[/tex]
[tex]\frac{2}{9}[/tex] * 4 = [tex]\frac{8}{36}[/tex]
[tex]\frac{3}{2}[/tex] * 18 = [tex]\frac{54}{36}[/tex]
2. Substitute the values back into the equation, and solve
[tex]\frac{3}{4}[/tex] - [tex]\frac{2}{9}[/tex] + [tex]\frac{3}{2}[/tex]
= [tex]\frac{27}{36}[/tex] - [tex]\frac{8}{36}[/tex] + [tex]\frac{54}{36}[/tex]
= [tex]\frac{19}{36}[/tex] + [tex]\frac{54}{36}[/tex]
= [tex]\frac{73}{36}[/tex]

The period of a pendulum is the time the pendulum takes to swing back and forth. The function relates the length L= 0.81t in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 90 feet long. Find the period.
Answer: 111.11 seconds
Step-by-step explanation:
Given: The period of a pendulum is the time the pendulum takes to swing back and forth
The function relates the length [tex]L= 0.81t[/tex] in feet of a pendulum to the time t in seconds that it takes to swing back and forth.
If L= 90 feet then put this in the above function, we get
[tex]90=0.81t\\\\\Rightarrow\ t=\dfrac{90}{0.81}\\\\\Rightarrow\ t=111.1111111\approx111.11\text{ seconds}[/tex]
Hence, the period = 111.11 seconds

The length a rectangular pan is represented by 5a2 and the area of the rectangular pan is represented by 5a4 + 10a3 - 15a2, find the polynomial expression that represents the width of the pan. Write your answer in descending order. Please use the palette below to enter your answer
Answer:
[tex]Width = a^2 + 2a - 3[/tex]
Step-by-step explanation:
Given
[tex]Area = 5a^4 + 10a^3 - 15a^2[/tex]
[tex]Length = 5a^2[/tex]
Required
Determine the Width
The area of a rectangle is calculated using:
[tex]Area= Length * Width[/tex]
Make Width the subject
[tex]Width = \frac{Area}{Length}[/tex]
Substitute values for Area and Length
[tex]Width = \frac{5a^4 + 10a^3 - 15a^2}{5a^2}[/tex]
Factorize the numerator
[tex]Width = \frac{5a^2(a^2 + 2a - 3)}{5a^2}[/tex]
[tex]Width = a^2 + 2a - 3[/tex]
Hence, the polynomial for the width of the rectangle is:
[tex]Width = a^2 + 2a - 3[/tex]
PROBLEM. Riley has a rectangular shaped patio that is 13 feet long by 15 feet wide. He wants to DOUBLE THE AREA of the patio by increasing the length and width by the same amount. 1. Write an EQUATION that represents the total area of Riley's proposed patio. AND 2. To the NEAREST TENTH of a foot, what is the LENGTH and WIDTH of the new patio?
Answer:
18.8 ft
20.8 ft
Step-by-step explanation:
Given that :
Dimension of rectangular patio:
13 feets * 15 feets
To double the area of The patio :
2 * initial. Area
Initial Area = area of rectangle = Length * width
Initial area = 13 * 15 = 195ft²
New area of patio = 2 * 195 ft² = 390 ft²
To obtain the new area, the length and width of patio increased in equal amount:
Let the Increment = x
Hence,
(length + x) * (width + x) = 390
(13 + x) * (15 + x) = 390
195 + 13x + 15x + x² = 390
195 + 13x + 15x + x² - 390 = 0
x² + 28x - 195 = 0
Using the quadratic equation solver to save computation time :
The roots are :
X = - 33.773 or 5.773
Dimension can't be negative, hence,
x = 5.773
New dimension :
(length + x) = 13 + 5.773 = 18.8 ft
(width + x) = 15 + 5.773 = 20.8 ft

Which first step for solving the given system using substitution results in an equation without fractions? Solve for x in the first equation. Solve for y in the first equation. Solve for x in the second equation. Solve for y in the second equation.
Answer:
solve for x in the second equation is correct
Step-by-step explanation:
Here is the complete question
Which first step for solving the given system using substitution results in an equation without fractions?
(2x+6y=7
(6x + 18y = 24.... 2
Solve for x in the first equation,
Solve for y in the first equation,
Solve for x in the second equation
The best equation to she will be equation 2 since all the coefficients are end numbers
Let us make x t subject f the formula from equation 2;
From 2: 6x+18y = 24
Subtract 18y from both sides
6x+18y-18y = 24-18y
6x = 24-18y
Divide through by 6
6x/6 = 24/6 - 18y/6
x = 4-3y.
You can see that the resulting expression of x is not a fraction. Hence solve for x in the second equation is correct

Write a multiplication equation that represents the question: how many 38s are in 54? DO NOT tell me the answer just show me how you worked it out using MULTIPLICATION. Thanks.
Answer:
[tex]38 x = 54[/tex]
Step-by-step explanation:
Required
Determine the number of 38 in 54
We start by representing the number of 38 in 54 with x
To determine the number of 38 in 54, we have to represented it as thus:
[tex]38 * x = 54[/tex]
Simplify the expression as follows:
[tex]38 x = 54[/tex]
The expression can be left like that or simplified further by dividing through by 2:
[tex]19x = 27[/tex]
Hence, the solution to the question is:
[tex]19x = 27[/tex] or [tex]38 x = 54[/tex]

A new arcade opened up in town. A play package is available to purchase. It includes 15 tokens for games,plus 5 dollars off. Let x represent the cost per token
Answer:
The total cost of the games (play package)
= 15x - 5
Step-by-step explanation:
Number of tokens in the games = 15
The cost per token = x
Discount off the total cost = $5
Therefore, the cost of the play package = 15x - 5
where x is in dollars
However, ‘x’ can also assume any value.
Check:
If x = $15
The total cost of the game can be said to be 15(10) - 5 = $220
Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6,4%. What is the total cost for the coat? Round to the nearest cent
Answer:
$79.7468
Step-by-step explanation:
6.4% of 74.95 is 4.7968, since 6.4 * 74.95 is 479.68, and if you divide that by 100, you will get 4.7968. 4.7968 + 74.95 = $79.7468
Here we want to find the total cost of a coat given that we know its cost and the sales tax.
By working with percentages, we will find that the total cost will be $79.75
Applying the tax:
So the cost of the coat is $74.95, and then we must pay an extra 6.4%
Then we must pay a total of the 100% + 6.4% = 106.4%
And the 100% is equivalent to $74.95
Then the 106.4% is equivalent to:
(106.4%/100%)$74.95 = $79.75
So the total cost of the coat is $79.75

Answer:
$58.5Step-by-step explanation:
Step one:
given data
the total amount of ounces= 97.5 ounces
we are told that the capacity of one bottle is 7.5 ounce
this means that they can actually fill up 97.5/7.5= 13 bottles
Step two:
We are told that one bottle was sold for $4.5
Hence they will sell 13 bottles for 13*4.5= $58.5
