Answer:

Step-by-step explanation:

find the first, second, and third term using the equation and check them with the options

f(1) = -8(1) + 18 = -8 + 18 = 10

f(2) = -8(2) + 18 = -16 + 18 = 2

f(3) = -8(3) + 18 = -24 + 18 = -6

which sequence has 10, 2, -6, ...? B.

Answer:

B. 10, 2, -6, -14, ...

Step-by-step explanation:

substitute each sequence from the options into the function f(n) = -8n + 18

It has one solution (1,0)

Step-by-step explanation:

y = -2x + 2

y = 4x -4

Substitute the y's

4x - 4 = -2x + 2

Let's move the variables to one side

4x - 4 = -2x + 2

+2x +2x

6x - 4 = 2

Lets move the constant to the other side

6x - 4 = 2

+4 +4

6x = 6

Divide both sides by 6

6x/6 = 6/6

x = 1

Let go back to y = -2x + 2

Substitute the x with 1

y = -2(1) + 2

y = -2 + 2

y = 0

Answer: 2 1/3 cubic inches

Step-by-step explanation:

Perhaps you want to know the volume of the prism in cubic inches.

Find the total volume of the smaller cubes:

63(1/3 in)^3 = 63/27 in^3 = 7/3 in^3 = 2 1/3 in^3

Factor the expression over the complex numbers.<br><br><img src="https://tex.z-dn.net/?f=%20x%5E%7B2%7D%20%2B18" id="TexFormula1

AleksAgata [21]

Here we are given the expression:

$x^{2}+18$

Now let us equate it to zero to find x first,

$x^{2}+18=0$

Now subtracting 18 from the other side,

$x^{2}=-18$

taking square root on both sides,

So we will get two values of x as ,

$x=3\sqrt{-2}$

$x=-3\sqrt{-2}$

Now we can write square root -1 as i,

So our factors become,

$x=3i\sqrt{2}$

$x=-3i\sqrt{2}$

Answer:

The final factored form becomes,

$(x+3i\sqrt{2})(x-3i\sqrt{2})$

MatroZZZ [7]

Answer:

16.25

Step-by-step explanation:

Well, the school is 13/2 miles away.

13/2 = 6.5

Since Edward goes by car there and back, he travels 13 miles a day.

6.5 x 2 = 13

He went for 5 days.

5 x 13 = 65

The car consumed 4 gallons of gas by driving those 65 miles.

65 / 4 = 16.25

Therefore, Edward's car gets 16.25 miles per gallon!
