Answer:

No real solution- Not any of the options anyway

Step-by-step explanation:

So I replaced the x's with the two possible equations and then tried to solve...

2=4+(4x2-4)1/2

2=4+(8-4)1/2

2=4+(4)1/2

2=8(1/2)

2=4 Which is not true

10=4+(4x10-4)1/2

10=4+(40-4)1/2

10=4+36(1/2)

10=40(1/2)

10=20 Which is also not true

Therefore, there is no real solution

Given the function f(x) =-x^2-1, find the value of f(1/3) in simplest form

Nimfa-mama [501]

Answer:

$-1\frac{1}{9}\ or -\frac{10}{9}$

Step-by-step explanation:

To solve this, we have to plug in 1/3 for x:

$f(\frac{1}{3})=-(\frac{1}{3})^2-1=-(\frac{1^2}{3^2})-1=-\frac{1}{9}-1=-1\frac{1}{9}\ or -\frac{10}{9}$

Martha Jackson had a $396.25 average monthly expenditure for clothing during the first quarter of the year. She spent $401.50 in

Sladkaya [172]

Answer: Martha spend $537.25 in june to have the same average as in the first quarter.

Step-by-step explanation:

Given that,

Average monthly expenditure for the first quarter= $396.25

Expenditure in April= $401.50

Expenditure in May= $250.00

Suppose, expenditure in June= x

To have the same average as in the first quarter, we have to take the average of the second quarter equals to the average of first quarter.

So,

Average monthly expenditure for the second quarter= $396.25

Using the formula of average for monthly expenditure for second qaurter as follow:

Average monthly expenditure for months April, May, and June= Sum of expenditure of April, May, and June divided by 3.

So,

396.25= (401.50 + 250.00 + x)/3

1188.75= 651.5 + x

x= 537.25

Use a geometric model to factor x^2-6x+8 by following these steps

belka [17]

Answer: (x−2)(x−4)

Step-by-step explanation: Let's factor x2−6x+8

x2−6x+8

The middle number is -6 and the last number is 8.

Factoring means we want something like

(x+_)(x+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -6

Multiply together to get 8

Can you think of the two numbers?

Try -2 and -4:

-2+-4 = -6

-2*-4 = 8

Fill in the blanks in

(x+_)(x+_)

with -2 and -4 to get...

(x-2)(x-4)

Which choice is the explicit formula for the following geometric sequence?

AnnZ [28]

The formula is x/-5, or divide by -5, however you would rather write it.
0.5 / -5 = -0.1
-0.1 / -5 = 0.02
0.02 / -5 = -0.004
