Answer:

Step-by-step explanation:

If you were to plot these coodinates on an x-y coordinate plane, you would see that it is a perfectly horizontal line through y = 3. The x coordinates can range from negative infinity to positive infinity, but every x value has a y coordinate of 3. That, then, is the equation of the line. y = 3

Anchara drops a penny from a height of 60 feet above the ground. The equation h=-16t^2 + 60 models the penbys height h i feet as

weeeeeb [17]

Answer:

t = 1.94 seconds

Step-by-step explanation:

we have to solve the following polynomial equation:

-16t² + 60 = 0

16t² = 60

t² = 60/16 = 3.75

t = √3.75 = 1.936491673 seconds

the equation also has another possible answer = -1.936491673 seconds, but since time cannot be negative, we have to dismiss that option

Which number should each side of the equation 4/5x=8 be multiplied by to produce he equivalent equation of x=10?

gulaghasi [49]

<< Add $.\frac{-4}{5}$ to the left and right of the equation, multiple and make ''opposite multiplation'' to find x.

A) $\frac{4}{5x}. \frac{-4}{5} = 8. \frac{-4}{5} 
$
$\frac{16}{25x} = \frac{-32}{5}$
25x.(-32)= (-16).5
-800x= -80

**to leave x alone and positive, you must divide to -800.
$x= \frac{-80}{-800}$
$x= \frac{1}{10}$
= INCORRECT

B) $\frac{4}{5x} . \frac{1}{5} = 8. \frac{1}{5} 
$
$\frac{4}{25x} = \frac{8}{5}$
$25x.8= 4.5$
$200x=20
$
$x= \frac{20}{200} = \frac{1}{10}$

C) $\frac{4}{5x} . \frac{5}{4}= \frac{8.5}{4}$
$\frac{1}{x} = \frac{40}{4}$
$\frac{1}{x} =10$
10x=1
$x= \frac{1}{10}$

D) $\frac{4.5}{5x} = 8.5$
$\frac{4}{x} = 40$
40x= 4
x= $\frac{4}{40}$ = 1/10

I think there is a problem with the options :D

Find 4 x f(x) if f(x)=-3x-8

VLD [36.1K]

Replace f(x) in the equation with what it equals:

$4 \times (-3x - 8)$

Distribute 4 to each term in parentheses:

$4 \times -3x = -12x$
$4 \times -8 = -32$

$-12x - 32$

The answer is C.

Identify the missing term in the following geometric sequence:

aleksley [76]

Answer:

B. -1/8

Step-by-step explanation:

Using the terms given in the sequence:

4, -2, 1, -1/2, 1/4

we can find the pattern by dividing since it is a geometric seqence:

-2/4 = -1/2

1/-2 = -1/2

-1/2 ÷ 1 = -1/2

So, each term is multiplied by -1/2 to get the next term in the sequence:

$\frac{1}{4}*-\frac{1}{2}=-\frac{1}{8}$
