Answer:
r = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to [tex]\frac{1}{7}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 9, - 3) and (x₂, y₂ ) = (- 2, r)
m = [tex]\frac{r+3}{-2+9}[/tex] , that is
[tex]\frac{r+3}{7}[/tex] = [tex]\frac{1}{7}[/tex] ( cross- multiply )
7(r + 3) = 7 ( divide both sides by 7 )
r + 3 = 1 ( subtract 3 from both sides )
r = - 2

Use a system of equations to find two numbers with a difference of 2 and a sum of -8. Show your work.
Answer:
-3 & -5
Step-by-step explanation:
let the two numbers be x and y
x + y = -8. sum of the numbers is -8
x - y = 2. difference(-) of the numbers is 2
now we add the two equations
x + x + y - y= -8 + 2
2x = -6
x = -6/2. = -3
substitute value of x in second equation to get y
-3 - y = 2
-y = 2 + 3
-y = 5
y = -5

The house is split into two cubes: The main house, and the "chimney"
The volume of the main part of the house is 20*20*21 mm=8,400mm cubed
The chimney's volume = 11*5*2mm = 110 mm cubed
Now, you just need to add them up.
8,400+110 mm cubed = 8,510 mm cubed

3.56 crates
35.6 crates
356 crates
3,560 crates
Answer: 356 crates
Step-by-step explanation:
1 pound = 16 ounces
Then 160 ounces = 10 pounds
if 1 crate is of 10 pounds then 3560 pounds contains 3560/10 crates
Answer & Step-by-step explanation:
1 pound = 16 ounces
160 ounces = 10 pounds
if 1 crate is 10 pounds then 3560 pounds contains 3560/10 crates.
The answer is 356 crates.

A flat-screen television costs $724.89 when it is new. The value of the television is expected to change by −12 3/5% per year. What is the expected value, to the nearest cent, of the television after 4 years?
The solution is $ 422.98
The expected value of the television after 4 years is $ 422.98
What is exponential growth factor?
The exponential growth or decay formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( t ) is the value at time t
x₀ is the initial value at time t = 0.
r is the growth rate when r>0 or decay rate when r<0, in percent
t is the time in discrete intervals and selected time units
Given data ,
Let the initial amount of the television be x₀
The value of x₀ = $ 724.89
Now , value of the television is expected to change by -12 3/5 % per year
So , the exponential decay rate of the television is r = -12 3/5 %
The rate r = -63/5 %
The rate r = -12.6 %
The number of years t = 4 years
So , the exponential decay rate of the television after 4 years is calculated from the formula
x ( t ) = x₀ × ( 1 + r )ⁿ
Substituting the values in the equation , we get
x ( 4 ) = 724.89 ( 1 - ( 12.6/100 ) )⁴
On simplifying the equation , we get
x ( 4 ) = 724.89 ( 1 - 0.126 )⁴
x ( 4 ) = 724.89 ( 0.874 )⁴
x ( 4 ) = 724.89 x 0.583506543376
x ( 4 ) = $ 422.978
So , rounding to the nearest cent , we get
The value of x ( 4 ) = $ 422.98
Hence , The expected value of the television after 4 years is $ 422.98
