If p(4) = 16 then
n*4² + 8 = 16
16n + 8 = 16
16n = 16 - 8
16n = 8
n = 8/16 = 0.5

If n = 0.5 then
p(-3) = 0.5*(-3)² + 8
p(-3) = 0.5 * 9 + 8
p(-3) = 4.5 + 8
p(-3) = 12.5

A plane is flying from Albuquerque new Mexico to Austin Texas so far it has flown 161 miles or 23% of the total distance of the
Karo-lina-s [1.5K]

Answer: 700 miles.

Step-by-step explanation:

1. You know that 23% of the total distance of the flight from Albuquerque New Mexico to Austin Texas is 161 miles.

2. Then, keeping that information on mind, you can calculate the total distance of the flight (which you call x) as following:

\frac{161miles}{23\%}=\frac{x}{100\%}

Solve for x. Then, you obtain that the result is:

x=\frac{161miles*100\%}{23\%}\\x=700miles

Write the equation of the line that passes through (-2,0) and (0, -7)
MakcuM [25]

Answer:

Step-by-step explanation:

1.

(-2,0) (0,-7)                y2-y1

                            -----------------

                                 x2-x1

-7-0= -7

0- (-2)= 2             ------>>> -7/2 =m or slope

2.

y= -7/2x+b          to find b u plug in one pair of coordinates for example (-2,0)

                          and use inverse properties to find b

0 = -7/2(-2) + b

       14/2 = 7

0= 7+b

-7 -7

-----------

-7=b

3.

y=-7/2x-7

The digit \greenD88start color #1fab54, 8, end color #1fab54 in which number represents a value of 888 thousandths?
Arte-miy333 [17]

<em>Question:</em>

<em>The digit 8 in which number represents a value of 8 thousandths? </em>

Answer:

See Explanation

Step-by-step explanation:

The question requires options and the options are missing.

However, the following explanation will guide you

Start by representing 8 thousandths as a digit

\frac{8}{1000} = 0.008

i.e.

8 thousandths implies 0.008

Next;

Replace the 0s with dashes

_ . _ _8

Note that there are two dashes after the decimal point and before 8

PS: The dashes are used to represent digits

This implies that thousandths is the 3rd digit after the decimal point

Typical examples to back up this explanation are:

<em>17.008, 1.1489, 0.008 and so on...</em>
