A line that includes the points (4,j) and ( – 8, – 9) has a slope of 16 . What is the value of j?

Answer:

so the first awnser is 90 and i am verry sorry but i do not know how to do the second one and the third does not have enogh information

Step-by-step explanation:

1. so first 12 inches is one foot, multiply 12 by 60 to get 720 now because it says that 1 inch is 8 feet and 720 is how manny inches it is so 720 divided by 8 is 90.

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

Answer:

12.6

Step-by-step explanation:

If 21 divided by 5 is 4.2, you should multiply 3 by 4.2 you'll then get 12.6. to double check, do 5 divided by 3, which is 1.67, and 21 divided by 12.6 is also 1.67. so side OP is 12.6! :)

Answer:

m=2/3

Step-by-step explanation:

The equation for slope:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

where y1=-1, y2=3, x1=-2, x2=4

[tex]m=\frac{3-(-1)}{4-(-2)}[/tex]

[tex]m=\frac{4}{6}[/tex]

which can be reduced to

[tex]m=\frac{2}{3\\}[/tex]

Answer:

The bicyclist rides (64) miles in (4) hours.

Step-by-step explanation:

As you can see the 64 is on the Distance side, so that shows how far he or she travels.  Then you can see on the bottom of the graph it shows you time in hours. The point is at 4, so he or she travels 64 miles in 4 hours.

-x+7=-0.5(x-3)^2+8

-x+7=-0.5x^10 -4.5^10

am I getting ...!?

Answer:

(-1,6) and (-7,0)

Step-by-step explanation:

-x+7=-0.5(x-3)^2+8

times both sides by -2

2x-14=(x-3)^2-16

expand

2x-14=x^2-6x+9-16

add 14-2x to both sides

0=x^2-8x+7

factor

0=(x-7)(x-1)

set to zero

0=x-7

7=x

0=x-1

1=x

so find y

y=-x+7

y=-1+7

y=6

or

y=-7+7

y=0

Answer:

6.6 inches

Step-by-step explanation:

4.1 times 3 = 12.3

2.2 times 3 = 6.6

I think this is right... sorry if not

Answer:

x = 6.6

Step-by-step explanation:

In order to solve the missing variable, we need to find the scale factor. I'll just take 12.3 and divide it by its corresponding side that is 4.1.

SF = 12.3/4.1 = 3

Now that we know the scale factor is 3, we can take 2.2 and multiply it by 3 to solve for x.

2.2(3) = 6.6

Therefore, x = 6.6.
