It's linear, so its proportional/has a relationship.

The y/x thing means slope, so take the slope -- which is 9.

What is an equation of the line that passes through the point (3,-1)(3,−1) and is parallel to the line 5x+3y=65x+3y=6?

Answers

Step-by-step explanation:

5x+3y = 6

5x = 6 - 3y

5x = 3(2-y)

5x/3 = 2 - y

y = 2 - (5x/3)

slope = x coefficient.

= - 5/3

Perpendicular slopes must be opposite reciprocals of each other:  m1 * m2 = –1

new slope = 3/5

the equation formula

y = mx + b

m = new slope = 3/5

y = (3x/5) + b

From the point given (3 , -1 )

x = 3.

y = -1

-1 = (9/5) + b

b =( -5/5) - (9/5)

b = - 14 / 5

[tex]y = \frac{3}{5} x - \frac{14}{5} [/tex]

x is 5 years older than y.Z is 6 years older than x how old are each person if the sum of their ages is 31

Answers

x is five years older than y
x= 5+y
(Adding 5 years to y will make both equal)

z is 6 years older than x
z= 6+x
In terms of y:
z= 6 + (5+y)

x+y+z = 31
(5+y) + y + 6 + (5+y) = 31
16 + 3y =31
3y = 15
y= 5

The three ages are
y= 5
x= (5+y) = 10
z= (6+5+y)= 16

16+10+5= 31

Step-by-step explanation:

Given

[tex]\frac{1}{f}[/tex] = [tex]\frac{1}{v}[/tex] + [tex]\frac{1}{u}[/tex]

Multiply through by fuv to clear the fractions

uv = fu + fv ( subtract fv from both sides )

v(u - f) = fu ← divide both sides by (u - f)

v = [tex]\frac{fu}{u-f}[/tex]

An angle is 34º more than its compliment. What is the measure of the angle?
a. 649
b. 1240
c. 28°
d. 62°

Answers

Answer: C. 28°

Explanation:
Two angles are complementary when they add up to 90 degress.

You have two angles. A & B
Equation 1: A+B=90
Equation 2: A+34=B

Solve equation 1 for one of the variables
I solved for A
A=90-B

Now plug (90 - B) into equation 2 for A

(90-B)+34=B Simplify

124-B=B Add B to both sides

124=2B Divide both sides by 2

62=B

Now plug 62 into equation 1 for B

A+62=90
A=28

“reflection across y= -1” HELP

Answers

Answer:

the orange line is the reflection y=-1

To plot the reflection of a function across the line y = -1, you'll need to follow these steps:Understand Reflection Across a Line: Reflection across a line involves flipping the points of the original function over the given line.

For reflection across the line y = -1, you'll be swapping the positions of the points above the line with those below it.

Choose a Function: Let's say you want to plot the reflection of a function f(x) across y = -1. Choose a function that you want to reflect. For demonstration purposes, let's consider a simple quadratic function, [tex]f(x) = x^2.[/tex]

Calculate the Reflected Points: To calculate the reflected points, follow these steps for each point (x, y) on the original function:

a. Find the vertical distance between the point and the reflection line (y = -1). This distance is the difference between the original y-coordinate and -1: distance = y - (-1) = y + 1.

b. The reflected y-coordinate (y') will be -1 minus the distance calculated in the previous step: y' = -1 - distance = -1 - (y + 1) = -2 - y.

c. The x-coordinate remains the same: x' = x.

d. The reflected point is (x', y').

Plot the Reflected Points: Plot the original function f(x) and then plot the reflected points (x', y') that you calculated in the previous step. This will show you the reflection of the function across y = -1.

Please also show your work too so others and I can understand. Thanks in advance!

Answers

Answer:

[tex]\displaystyle \text{(1)}\\x=1+\sum_{k=1}^{n-1}2k\\\\\text{(2)}\\\displaystyle \frac{\displaystyle \sum_{k=1}^{n}2k\left(1+\displaystyle \sum_{k=1}^{n}2k \right)}{2}-\frac{\displaystyle \sum_{k=1}^{n-1}2k\left(1+\displaystyle \sum_{k=1}^{n-1}2k \right)}{2}[/tex]

Step-by-step explanation:

Notice that Group 1 starts with 1 and we keep counting up by 1.

Part 1:

The total number of numbers from Group 1 to Group [tex]n[/tex] can be found by:

[tex]\displaystyle \sum_{k=1}^{n}2k[/tex]

To find the first number in a certain group [tex]g[/tex], we'll find the total number of numbers from Group 1 to Group [tex]g-1[/tex], then add 1.

Here's why.

Let's say we want to find the first number of Group 3, which we can clearly see is 7. Take advantage of the fact that the sequence of numbers counts up by 1, starting from 1. We will use the formula above to to find the total number of numbers from Group 1 to Group 2, which is 6, then add 1 to achieve the number of 7.

Therefore, the first number in group [tex]n[/tex] must be:

[tex]\boxed{\displaystyle 1+\sum_{k=1}^{n-1}2k}[/tex]

Part 2:

Recall that the sum of the numbers from [tex]1[/tex] to positive integer [tex]n[/tex] inclusive is given by [tex]\displaystyle\frac{n(n+1)}{2}[/tex].

Therefore, if we find the total number of numbers from Group 1 to Group [tex]n[/tex], we can simply substitute that value into the formula above to find the total sum of the numbers from Group 1 to Group [tex]n[/tex].

To find the total sum of the numbers exclusively in Group [tex]n[/tex] simply subtract the sum of numbers from Group 1 to Group [tex]n-1[/tex].

Short example on how that works:

The sum of all numbers in Group 3 is equal to the sum of the numbers from Group 1 to Group 3 minus the sum of the numbers from Group 1 to Group 2.

We've already found the formula for the total number of numbers from Group 1 to Group [tex]n[/tex] in the previous part, so convert this concept into summation notation like such:

[tex]\boxed{\displaystyle \frac{\displaystyle \sum_{k=1}^{n}2k\left(1+\displaystyle \sum_{k=1}^{n}2k \right)}{2}-\frac{\displaystyle \sum_{k=1}^{n-1}2k\left(1+\displaystyle \sum_{k=1}^{n-1}2k \right)}{2}}[/tex]
