I need the answer to y=2x+7 in a graph and passes through (3,3)
I need the given, parallel, slope intercept form
Answers
The slope-intercept form is y = 2x-3.
Step-by-step explanation:
Given,
The equation of the line is y=2x+7.The general equation of the line is in the form y= mx+c.where 'm' represents the slope of the line.Comparing the given equation with general equation, it can be determined that :
m = 2 and c = 7 (y-intercept).
The given line passes through the point (3,3) which is equal to (x1,y1)
Therefore, x1=3 and y1=3.
Substitute m=2 and the values of (x1,y1) in the slope-intercept form,
The slope-intercept form is (y-y1) = m (x-x1)
(y-3) = 2(x-3)
y = 2x-6+3
y = 2x-3

The length of a rectangle is one foot more than twice it’s width. if the area of the rectangle is 300 ft.² find the dimensions of the rectangle
Answers
Answer:
Length= 12 ft
Width= 25 ft
Step-by-step explanation:
We will use the area of the rectangle formula to solve this question. The formula is: [tex]Area= length* width[/tex]
Let, the width of the rectangle is x, so the length is one foot more than twice it’s width, and is written as:
width= 2x+1
Now the area of the rectangle is given as:
300 [tex]ft^2[/tex]
So using the formula of the area of a rectangle, we get:
[tex]Area= length* width\\\Rightarrow 300= x(2x+1)\\\Rightarrow 2x^2+x-300=0\\\Rightarrow x=\frac{-1 \pm \sqrt{1^2-4 \cdot \:2\left(-300\right)}}{2\cdot \:2}\\\Rightarrow x=12,\:x=-\frac{25}{2}\\[/tex]
But we will take only positive value of x, as length can't be negative.
So the dimensions of the rectangle are:
Length= 12 ft
Width= 25 ft
To solve for the dimensions of the rectangle with an area of 300 square feet and a length one foot more than twice its width, you begin with the formula for the area of a rectangle. After setting up the quadratic equation, solving it yields a width of 10 feet and a length of 21 feet, making the dimensions 10 feet by 21 feet.
Explanation:To find the dimensions of a rectangle where the length is one foot more than twice its width, and the area is 300 square feet, you set up two equations based on the given information.
Let the width be w feet. Then, the length l would be 2w + 1 feet. The area A of a rectangle is given by the formula A = w × l. Substituting the known area and the expression for l, we have 300 = w × (2w + 1).
To solve for w, we should solve the quadratic equation w^2 + w - 150 = 0. Factoring the quadratic, we get (w - 10)(w + 15) = 0. This gives us two possible solutions for the width: w = 10 or w = -15. Since a negative width doesn't make sense in this context, we use w = 10 feet. The length is thus 2 × 10 + 1 = 21 feet.
Therefore, the dimensions of the rectangle are 10 feet by 21 feet.

Step-by-step explanation:
You break down each number Then you need to "add" them Then finally you add them together to make sure you have the right answerThe height of a puffin in expanded form is [tex]\(2 \times 10^1 + 4 \times 10^0 + 0 \times 10^{-1} + 2 \times 10^{-2}\) cm[/tex].
To write the height of a puffin, which is 24.02 cm, in expanded form, we need to express each digit as a product of the digit and its corresponding power of 10. Starting with the leftmost digit:
- The first digit is 2, and it is in the tens place, so it is [tex]\(2 \times 10^1\)[/tex].
- The second digit is 4, and it is in the ones place, so it is [tex]\(4 \times 10^0\)[/tex] (since any number to the power of 0 is 1).
- The third digit is 0, and it is in the tenths place, so it is [tex]\(0 \times 10^{-1}\)[/tex]. Since it is multiplied by 0, this term contributes nothing to the total and can be omitted.
- The fourth digit is 2, and it is in the hundredths place, so it is [tex]\(2 \times 10^{-2}\)[/tex].
Putting it all together, we get the expanded form as:
[tex]\(2 \times 10^1 + 4 \times 10^0 + 0 \times 10^{-1} + 2 \times 10^{-2}\) cm.[/tex]

What is center?The location is sometimes alluded to as the data collection's "core." The two metrics that are most frequently used to identify the "center" of both the data are the mean (average) and the median. To find the weighted mean of 50 people, add up all 50 weights once more and divide by 50.
Order the data and locate the number that divides the information into two equal portions to determine the median weight of both the 50 individuals. Because it is unaffected by the specific numerical values of the outliers, the median is typically a better indicator of the center if there are extreme values or outliers. The most popular way to measure the center is with the mean.

At a particular restaurant, each onion ring has 45 calories and each slider has 325 calories. A combination meal with onion rings and sliders is shown to have 920 total calories and 3 times as many onion rings as there are sliders. Write a system of equations that could be used to determine the number of onion rings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answers
Answer:
There were 6 onion rings and 2 slider in the combination meal.
Step-by-step explanation:
Let x be the number of onion rings and y be the number of slider.
Calories in one onion ring = 45 calories
Calories in one slider = 325 calories
Total number of calories = 920
Thus, we can write the equation:
[tex]45x + 325y = 920[/tex]
There are 3 times as many onion rings as the sliders.
Thus, we can write the equation:
[tex]x = 3y[/tex]
Solving the two equation by substitution method, we get,
[tex]45(3y) + 325y = 920\\460y = 920\\y = 2\\x = 3y = 3(2) = 6[/tex]
Thus, there were 6 onion rings and 2 slider in the combination meal.
The system of equations that can be used to determine the required values is:
45x + 325y = 920 equation 1
3x = y equation 2
Where:
x = total number of onions
y = total number of sliders
In order to determine the number of onions and sliders in the combination meal, equation 1 and 2 have to be solved together in order to determine the required values. This is known as solving equations simultaneously. They can be solved using two methods:

Perimeter of the new triangle is 1505 ft

Step 1: Given the perimeter of the right triangle = 215 ft. Find new perimeter.Perimeter of the triangle = sum of the sides = a + b + c = 215
Each side is multiplied by 7, so new sides are 7a, 7b, 7c

1. An inflatable beach ball has a circumference of 141.3 centimeters. What is the volume of the beach ball when fully inflated? Record your answers in cubic centimeters, round to the nearest whole number. Use 3.14 for pie.
2. Which exponent can be substituted for the letter x to make the equation true?
4^x=64
Answers
1) The volume of the beach ball when fully inflated is 47690 cubic centimeters.
2) The value of x is 3.
Step-by-step explanation:
It is given that, an inflatable beach ball has a circumference of 141.3 centimeters.
1) To find the volume of the beach ball :
Use the formula for volume of sphere to find the volume of beach ball when fully inflated.
Volume of sphere = (4/3)πr³
where, r is the radius of the sphere and π has the default value of 3.14.
To find the radius :
The given circumference is 141.3 = 2πr
⇒ r = 141.3 / 2π
⇒ r = 141.3 / (2×3.14)
⇒ r = 141.3 / 6.28
⇒ r = 22.5
Now, substituting r= 22.5 in the volume of sphere formula
Volume of sphere = (4/3) ×3.14× (22.5)³
⇒ 4/3 ×3.14 ×11391
⇒ (12.56×11391) / 3
⇒ 47690 cubic centimeters
The volume of the beach ball when fully inflated is 47690 cubic centimeters.
2) The given equation is [tex]4^{x} = 64[/tex]
⇒ 64 = 4×4×4
⇒ 64 = 4³
Therefore, the value of x is 3.
Final answer:
The volume of the beach ball when fully inflated is approximately 48,000 cubic centimeters. To find the exponent x that makes the equation 4^x=64 true, we see that x must equal 3, since 64 is 4 cubed.
Explanation:
To calculate the volume of an inflatable beach ball with a circumference of 141.3 centimeters, we first need to determine its radius. The formula connecting circumference (C) and radius (r) of a sphere is C = 2πr. Using 3.14 for π, we can rearrange to find r: r = C / (2π).
r = 141.3 cm / (2 × 3.14)
= 141.3 cm / 6.28
= 22.5 cm (approximately)
Now, we can use the formula for volume of a sphere which is V = (4/3)πr³. Plugging in the value of the radius, we get:
V = (4/3)× 3.14 × (22.5)³
= (4/3)× 3.14 × (11,390.625 cm³)
= 48,000 cm³ (approximately)
The volume of the beach ball is approximately 48,000 cubic centimeters when fully inflated, rounding to the nearest whole number.
For the second part of the question, we want to find the exponent x that equates 4 raised to the power x to 64. Since 64 is 4 cubed (or 4³), we can easily see that x = 3 to make the equation 4³=64 true.
