Answer: r=1/2v−2
Step-by-step explanation:
v=4+2r
2r+4=v
2r+4+−4=v+−4
2r=v−4
2r/2=v−4/2
r=1/2v−2

In the figure above, rectangle V'W'X'Y' is a dilation of rectangle VWXY. What is the scale factor of the dilation?
A. 0.25
B. 2
C. 3/4
D. 1/4
Answer:
D. [tex] \frac{1}{4} [/tex]
Step-by-step explanation:
Rectangle VWXY after dilation, became compressed to rectangle V'W'X'Y'.
This makes both rectangles similar. It follows that the corresponding side lengths or segments of both figure would be proportional. Thus, the scale factor of the dilation would be:
[tex] \frac{W'X'}{WX} [/tex]
W'X' = 5
WX = 20
Plug in the values
[tex] \frac{5}{20} [/tex]
Simplify
[tex] scale factor = \frac{1}{4} [/tex]
f(x)= √x+3. Find the inverse of f(x) and it's domain
Step-by-step explanation:
f(x) = √x + 3
y = √x + 3
√x = y - 3
x = (y - 3)²
Hence inverse of f(x) = (x - 3)² and its domain is x >= 3.
The required domain of the inverse function F(x)= (x-3)^2 is given by ≥3
f(x)= √x+3
What is inverse function?The inverse function can be defined as the transverse of function.
F(x) = y
y = √x + 3
x= (y - 3)^2
or
for inverse function
F(x) = (x-3)^2
The domain of function is given by greater and equal to 3
The required inverse function is F(x) = (x-3)^2 and its domain is greater and equal to 3.

Answer:
The answer is
y = 6x + 43
Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the parallel line we must first find the slope of the original line
The original line is y = 6x + 1
Comparing with the general equation above
Slope = 6
Since the lines are parallel their slope are also the same
Slope of parallel line = 6
The equation of the line using point (-7,1) and slope 6 is
We have the final answer as
y = 6x + 43

➤ How to solve ?
⠀⠀⠀⠀
That's quite easy but you need to recall the BODMAS rule .
⠀⠀⠀⠀
BODMAS rule states the correct sequence to solve an equation . First we need to solve the bracket part then solve if any of is present moving further to division then multiplication carrying with addition atlast subtraction
⠀⠀⠀⠀
In this equation we will solve the bracket then we will apply further BODMAS rule
⠀⠀⠀⠀
━━━━━━━━━━━━━━━━━
SolutiOn :
➠ 7x + 31 = 8x - 1 ( 27x + 3 ) -3
➠ 7x + 31 = 8x - 27x - 3 - 3
Now, we will bring the variable on left hand side and constants on right hand side
➠ 7x - 8x + 27x = - 31 - 3 - 3
➠ 26x = -37
➠ x = -37/ 26
➠ x = - 1.42
∴ The value of x is -1.42 .

Graph the line that passes through the points (-2, - 7) and (5,0) and determine
the equation of the line.
Solve the system of equations by substitution. y = 2x y = x +1
Step-by-step explanation:
y = 2x
y = x + 1
y-1 = x
y = 2x
y = 2 (y - 1)
y = 2y - 1
y = -1

Find the x and y Intercepts
Answer:
x-intercept(s): (3,0)
y-intercept(s): (0,−2)
Step-by-step explanation:
Answer:
x=3 and y=-2
Step-by-step explanation:
2x - 3y = 6
cancel out the y
2x - 3(0) = 6
2x = 6
divide both sides by 2
x = 3
2x - 3y = 6
cancel out the x
2(0) - 3y = 6
-3y = 6
divide both sides by -3
y = -2
