Answer:

20

Step-by-step explanation:

I put it into a graphing calculator

and If u put -4 in for x u get:

-4^2= 16

g(-4)= 16 - (-4)

g(-4)= 20 bc 16 minus a negative 4 is a positive 20

Step-by-step explanation:

-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:

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.

Hope this helped.

Answer:

Reversed

Step-by-step explanation:

If you multiply each side by -1, then the equation becomes;

3 < (-4)

which is incorrect. The symbol would have to be the other way which means that the inequality symbol is going to be reversed.

Answer:

Reversed

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:

= $655.20

Step-by-step explanation:

Simple Interest =( Principal * rate * time)/100

                          =( $ 6300 * 2.60% * 4years)/100, workout in the brackets first then divide by 100.

                        =   65520/100

                        = $655.20

Dexter will earn $655.2.

Simple interest is the borrowing amount added only to the principal amount.

Formula to calculate the simple interest is;

                                                 S.I. = P x T x R / 100 ,

Where S.I. is simple interest , P is principal amount, T is time period and R is interest rate in a year.

Dexter deposited $6,300 into a savings account that earns 2.60% simple interest per year.

P = $6300

R = 2.60% and T = 4 years

Then by the formula;

6300 x 2.6 x 4 /100

= $655.2

Therefore, Dexter will earn $655.2.

Answer:

25. y=2x+1

26. $13

Step-by-step explanation:

25. 2x is the cost each day or the x, and the 1 is the initial fee, I found this because it said one day costs $3 and if I know that one days fee is $2 then I know that the y intercept or the price it starts at also known as a fee is $1. This is also backed up in the 4 day statement saying that 4 days is 9 dollars. I can do 9-1 to take away the fee and 8/2=4 so it is correct.

26. Since I already have the equation I can just plug in the vales and solve. y=2x+1, x=2 or the daily cost so 12+ (the fee) 12+1=13 so $13.

good luck, and have a great day.    :)

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:

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.
