The equation of the line that passes through the point (-1,5) and has a slope of 3 in point-slope form is y = 3x + 8.
Explanation:The subject of this question relates to Mathematics, specifically algebra and line equations. The line equation in point-slope form is given by y - y1 = m(x - x1). In this equation, (x1, y1) represents the point that the line passes through and m represents the slope of the line. In our case, we know that the line passes through the point (-1,5) and has a slope of 3.
By substituting these values into the point-slope formula, we get the following:y - 5 = 3(x - (-1)), or, after simplifying, y - 5 = 3x + 3. So, the equation of the line that passes through (-1,5) and has a slope of 3 is y = 3x + 8.

A bike wheel is 26 inches in diameter. What is the bike wheel's diameter in millimeters (1 inch = 25.4 millimeters)?
Given that, a bike wheel is 26 inches in diameter.
We need to convert bike wheel's diameter in millimeters .
Since, 1 inch = 25.4 millimeters.
So, to convert 26 into mm we need to multiply 26 each sides of this identity to convert this into mm. Hence,
1*26 inch = 25.4 * 26 mm.
So, 26 inches = 660.4 mm.
So, the bike wheel's diameter is 660.4 millimeters.
Hope this helps you!
The bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.
To convert a bike wheel's diameter from inches to millimeters,
we have to use the conversion factor, which is,
1 inch = 25.4 millimeters.
Now multiplying the diameter of the bike wheel,
which is given as 26 inches,
by the conversion factor of 25.4 millimeters per inch.
⇒ 26 inches x 25.4 millimeters per inch = 660.4 millimeters
Therefore, the diameter of the bike wheel in millimeters is 660.4 millimeters.
Therefore, we can convert inches to millimeters by multiplying by 25.4, which is the number of millimeters in one inch.
In this case, the bike wheel's diameter of 26 inches is equivalent to 660.4 millimeters.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?
Answer:
160 stamps
Step-by-step explanation:
Suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
The new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have

if √a/√b=x, which statement must be true? A. x^2=a/b B. √x=a/b C. |x|=a/b D. x=a/b
Answer:
x^2 = a/b
Step-by-step explanation:
[tex]\frac{\sqrt{a}}{\sqrt{b} } =x[/tex]
If we have square root at the top and bottom then we take single square root with fraction inside
[tex]\sqrt{\frac{a}{b}} =x[/tex]
To remove square root we take square on both sides because square and square root will get cancelled
[tex]\frac{a}{b}=x^2[/tex]
x^2 = a/b is true
The statement that must be true is:
[tex]x^2 = a/b[/tex]
How to find an equivalent expression?
To find an equivalent expression, we just need to rewrite the given expression.
Here we will use the fact that the square root is distributive with respect to the division, which means that we can rewrite:
[tex]\frac{\sqrt{a} }{\sqrt{b} } = x\\\\\sqrt{\frac{a}{b} } = x[/tex]
Now if we square both sides of that expression, we will get:
[tex]\sqrt{\frac{a}{b} }^2 = x^2\\\\\frac{a}{b} = x^2[/tex]
So we can see that the correct option is A.

Solve for x. 23=79(6x−36)+9 Enter your answer in the box.
The value of the equation 1429/237.
Let's solve for x in the given equation:
[tex]\[23 = 79(6x - 36) + 9\][/tex]
First, distribute the 79 on the right side:
[tex]\[23 = 474x - 2844 + 9\][/tex]
Combine like terms:
[tex]\[23 = 474x - 2835\][/tex]
Now, isolate the term with x by adding 2835 to both sides:
[tex]\[474x = 2858\][/tex]
Finally, divide both sides by 474 to solve for x:
[tex]\[x = \frac{2858}{474}\][/tex]
Now, you can simplify the fraction:
[tex]\[x = \frac{1429}{237}\][/tex]
So, the solution for x is [tex]\(x = \frac{1429}{237}\).[/tex]
Final answer:
To solve the equation, distribute the 79 on the right side, combine like terms, and then isolate and solve for x to get x = 6.05.
Explanation:
To solve the equation 23=79(6x−36)+9, we first expand the right side of the equation and then isolate the term with x on one side.
First, distribute the 79:
23 = 79(6x) - 79(36) + 9,
which simplifies to:
23 = 474x - 2844 + 9.
Combine like terms:
23 = 474x - 2835.
Now, add 2835 to both sides to isolate the term with x:
2868 = 474x.
Finally, divide both sides by 474 to solve for x:
x = 2868 / 474.
After performing the division, we find that x = 6.05.
What units would you use to describe the volume of a box measured in inches?
cubic inches or inches³ would we use to describe the volume of a box measured in inches.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law
Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units.
As volume we measure by using three dimensions so the unit will be in cubics.
If we have to measure volume of box in inches then it will be cubic inches or inches³.
Hence cubic inches or inches³ units would we use to describe the volume of a box measured in inches.

A parchment fragment was discovered that had about 61% as much 14c radioactivity as does plant material on earth today. estimate the age of the parchment. (round your answer to the nearest hundred years.)
The estimated age of the parchment is approximately 4,086.17 years.
To estimate the age of the parchment, we can use the concept of carbon dating.
Carbon-14 (14C) is a radioactive isotope of carbon that is commonly used for dating archaeological artifacts.
The amount of 14C in an organism remains relatively constant while the organism is alive because it continuously takes in carbon from the atmosphere and food.
However, after the organism dies, it no longer takes in new carbon, and the 14C begins to decay at a known rate.
The half-life of carbon-14 is approximately 5,730 years. This means that after 5,730 years, half of the original amount of carbon-14 in a sample would have decayed.
Let's use the information provided: the parchment fragment had about 61% as much 14C radioactivity as does plant material on Earth today.
This means that the remaining 14C in the parchment is 61% of the original amount. The remaining 14C is the amount that has not yet decayed, and the rest has decayed over time.
Now, we can set up an equation:
[tex]0.61 = (1/2)^{(t/5730)[/tex]
Where:
t = time in years since the parchment was alive.
Now, we need to solve for 't.' Taking the logarithm of both sides to isolate 't':
[tex]\log(0.61) = (t/5730) \times \log(1/2)[/tex]
Now, solving for 't':
[tex]t = (5730 \times \log(0.61)) / \log(1/2)[/tex]
Using a calculator, we find:
t ≈ 4,086.17 years
So, the estimated age of the parchment is approximately 4,086.17 years.

Using the concept of radiocarbon dating and the fact that the parchment has 61% as much 14C radioactivity as present plant material, the calculated estimate for the parchment's age is approximately 2,200 years, rounded to the nearest hundred years.
Explanation:To estimate the age of the parchment based on the information that it had about 61% as much 14C radioactivity as does plant material on Earth today, we use the concept of radiocarbon dating. The half-life of carbon-14 (14C) is 5,730 years, which means after every 5,730 years, the amount of 14C decreases by half. Given that the parchment retains 61% of its original 14C, we can formulate the decay equation to solve for the parchment's age.
The decay equation is given by: \(N_t = N_0(1/2)^{t/T}\), where \(N_t\) is the remaining amount of 14C, \(N_0\) is the original amount of 14C, \(t\) is time, and \(T\) is the half-life of 14C. In this case, \(N_t/N_0 = 0.61\), and we know \(T = 5730\) years.
By substituting the given values into the decay equation and solving for \(t\), we find that the parchment is approximately 2,200 years old, rounded to the nearest hundred years. This estimation assumes the natural 14C to 12C ratio in the atmosphere has been constant over the time period in question.
