Tell whether (2, 5) is a solution of the equation y = 2x + 1. Show your work. I’LL PUT YOU AS BRAINLIEST
Answer:
The solution of (2,5) indeed equals the solution of the equation y=2x+1
Step-by-step explanation:
to solve just plug in the values.
y=2(2)+1 which gives us the y value of y=5
to solve for x, plug in y. 5=2x+1.
subtract 1 from both sides, and you get 4=2x
then divide 2 on both sides to get x, which is 2. therefore this is true.

Answer:
Solution:
\(\frac{\left(y-1\right)^2}{9}-\frac{\left(x+4\right)^2}{4}=1\)
Step-by-step explanation:
We have the general equation for our up - down facing hyperbola as (y - k)² / b²- (x - h)² / a² = 1. Let's start listing the properties of this graph -
• Taking a look at the graph we see that the center point of our hyperbola here is (- 4, 1). Therefore (h, k) = (- 4,1).
• Another thing here is our key value a. This is the semi distance from the center to one of the vertices. Here it will be the distance from points (- 4,1) and (- 4,4) or 3 unit difference. Therefore a = 3.
• That leaves us with our asymptotes. Now remember that it will be in the form y = ± b / a. We already know a = 3, so we have to find b. Looking at this graph I can say that another point besides (- 4,1) that lies on the " dotted line " is (- 2, - 2). Calculating the slope of the dotted line would be as follows,
Given: (- 4,1) and (- 2, - 2)
Slope = - 2 + 4 / - 2 - 1 = 2 / 3
We have the equation y = 2 / 3x. Therefore b = 2. Let's substitute to receive our equation...
h = - 4, k = 1, b = 2, a = 3
(y - 1)² / (3)²- (x + 4)² / (2)² = 1
(y - 1)² / 9 - (x + 4)² / 4 = 1 ~ your solution is the last one, option d

A home that was built in 1980 has increased in value at a rate of 5% per year. It was originally sold for $75,000. What was it worth in 2005? Round your answer to the nearest dollar.
In 2005 it was worth $_____
Answer: Your answer would be $168,750
First you need to get 5% of 75,000 which is 3750
Next you have to mutiply 3750 by 25 because 1980 to 2005 is 25 years.
Which will give you 93,750
Then you add 93,750 with 75000 which is what it got sold for and your answer will be $168,750

The coordinate of the point S' after the rotation of quadrilateral RSTU is; S'(2, 3)
How to find the coordinate after rotation about a point?
A rotation is defined as a transformation in which the object is rotated about a fixed point. The direction of rotation can be clockwise or anticlockwise.
Now, we are told that the image RSTU is rotated 180 degrees and looking at the 3 new coordinates formed, we see that the rotation rule is as follows;
T(-2, 1) → T'(-2, 1)
U(-2, -5) → U'(-2, -7)
R(-6, -5) → R'(2, 7)
Now, it is pertinent to note that in rotation, the length of the sides remain the same and that is why we see that TU and T'U' are both 6 units in length.
Similarly, RS is 4 units in length and as such R'S' must be 4 units in length. When we count 4 units down from R', we will get the point S' which has the coordinate (2, 3). Thus, we have;
S(-6, -1) → S'(2, 3)

The measure of angle x is 77 degrees.
How to calculate the angleWe have two angles given: 65 degrees and 38 degrees. Let's call the measure of angle x as "x".
From the information, we have the measure of the missing angle of the angles in a triangle are 38°, 65° and x. Then we can set up an equation:
x + 65 + 38 = 180 (the sum of the measures of the angles in a triangle is 180)
Simplifying this equation, we get:
x + 103 = 180
x = 77

Olivia sold a car valued at $54 000. Calculate Olivia's commission from the sale if her rate of commission is 3%.
Answer:
$1620
Step-by-step explanation:
We know
Olivia sold a car valued at $54000. Her rate of commission is 3%.
3% = 0.03
Calculate Olivia's commission from the sale if her commission rate is 3%.
We take
54000 x 0.03 = $1620
So, Olivia's commission is $1620
a bike that goes from 6m/s to 16m/s in 20 seconds.
The initial velocity = vi = 6m/s
The final velocity = vf = 16 m/s
The total time = t = 20 seconds
The rate of change in velocity is called acceleration (a) that can be written as:
\(a\text{ = }\frac{Change\text{ in velocity}}{time}\)
or
\(a\text{ = }\frac{vf-vi}{t}\)Put the values in the equation to get the value of 'a'.
\(a\text{ = }\frac{16\text{ - 6}}{20}\)\(a\text{ = }\frac{10}{20}\)or
\(a\text{ = }\frac{1}{2}\)hence, the value of a is 1/2.

differentiate the following function g(x)3(x3-6)2(x2 4x-6)10
the derivative of function g(x) = \(3(x^3-6)^2(x^2 + 4x - 6)^{10} is:g'(x) = 3 * [2(x^3-6)(3x^2)(x^2 + 4x - 6)^{10} + (x^3-6)^2 * 10(x^2 + 4x - 6)^9(2x+4)]\)
To differentiate the function\(g(x) = 3(x^3-6)^2(x^2 + 4x - 6)^{10}\), we can use the chain rule and the power rule for differentiation.
Let's break it down step by step:
1. Start by differentiating the outermost function with respect to x. The outermost function is\((x^3-6)^2(x^2 + 4x - 6)^{10}\), which we'll call f(x). Let's denote it as \(f(x) = (x^3-6)^2(x^2 + 4x - 6)^{10}.\)
2. Differentiate f(x) using the product rule. Let's call the first factor (x^3-6)^2 and the second factor \((x^2 + 4x - 6)^{10}\). The derivative of f(x) is given by:
\(f'(x) = (2(x^3-6)(3x^2)) * (x^2 + 4x - 6)^{10} + (x^3-6)^2 * (10(x^2 + 4x - 6)^9(2x+4))\)
3. Simplify the expression:
\(f'(x) = 2(x^3-6)(3x^2)(x^2 + 4x - 6)^{10} + (x^3-6)^2 * 10(x^2 + 4x - 6)^9(2x+4)\)
4. Finally, substitute f(x) back into the expression to obtain the derivative of g(x):
g'(x) = f'(x) * 3

What do you mean by graphs?A diagram or pictorial representation that organizes the depiction of data or values is known as a graph.

Given,
We have a polynomial function f(x) = x⁴ - 3x³ + x - 3.
Now, we can assume some arbitrary values for "x" that correlate to some alternative values of "y" in order to graph this bi-quadratic polynomial.
At, x = 1, f(x) = (1)⁴ - 3(1)³ + (1) - 3 = - 4.
Similarly, At x = - 1, f(x) = 0.
Now, At = x = - 2, f(x) = 35.
Again at x = 2, f(x) = - 9.
Therefore, the coordinate points are, (1, - 4), (- 1, 0), (- 2, 35), and (2, - 9).

How many numbers between 1 and 10000 have the digits 1,3, and 5 such that each digit appears exactly once
There are 6 numbers between 1 and 10,000 with the digits 1, 3, and 5, where each digit appears exactly once.
To determine the number of numbers between 1 and 10,000 that have the digits 1, 3, and 5, with each digit appearing exactly once, we can consider the following:
The first digit can be either 1, 3, or 5 (3 options).
The second digit can be any of the remaining two digits (2 options).
The third digit can be the last remaining digit (1 option).
The fourth digit can be any of the remaining 7 digits (7 options).
Multiplying these options together, we get 3 × 2 × 1 × 7 = 42 possible numbers. However, since the number should be between 1 and 10,000, we need to exclude the possibility of having a leading zero. Therefore, the correct answer is 42 - 1 = 41 numbers.
So, there are 41 numbers between 1 and 10,000 that have the digits 1, 3, and 5, where each digit appears exactly once.

Samantha needs to mix a 20% fungicide solution with a 50% fungicide solution to create 100 millileters of a 29% solution. How many millileters of each solution must Samantha use
The amount of 20% and 50% solution that Samantha needs to mix is 70 milliliters and 30 milliliters respectively.
Let the amount of 20% solution that Samantha needs to mix be x millileters.
Therefore, the amount of 50% solution Samantha needs to mix will be (100 - x) millileters.
According to the question, Samantha needs to create 100 millileters of a 29% solution.
The expression below can be used to calculate the volume of the mixture obtained after mixing x milliliters of the 20% solution and (100 - x) milliliters of the 50% solution:
0.20x + 0.50(100 - x) = 0.29(100)
Simplifying and solving for x:
0.20x + 50 - 0.50x = 29
x = (29 - 50) / (-0.30)
x = 70 milliliters
Therefore, the amount of 20% solution that Samantha needs to mix is 70 milliliters.
And, the amount of 50% solution that Samantha needs to mix is 30 milliliters.

A:Y=15x+2
B:Y=-1/15x-8
c:y=-9x-7
D:y=1/5x-3
Answer:
y=1/5x-3
Step-by-step explanation:
Start by finding the slope:
Slope = (y₂-y₁)/(x₂-x₁)
Now we plug in the coordinates:
Slope = (12-(-3))/(-3-0)=(12+3)/(-3)=15/-3=-5
The slope intercept equation would be
y=mx+b
Slope is m and y-intercept is b. x and y and the x and y-coordinates.
Now we plug in one of the x and y coordinate pairs into the equation:
-3=-5(0)+b
b=-3
So the equation of the line would be
y=-5x-3
But the slope of a perpendicular line is the negative reciprocal of the original equation
So...
