This implies that,

Multiply both sides of the second inequality by -1 and reverse the inequality sign.

The graphical solution to this inequality is shown in the attachment.
Answer: a negative integer, rational number, and real number
Step-by-step explanation:
I don’t know exactly what you’re asking but here you go
by Quadratic formula ,
, values of x are
. None of mentioned options are correct according to question!
<u>Step-by-step explanation:</u>
Here we have , expression x2 + 20 = 2x or ,
.
We know that Quadratic formula is :


⇒ 

Putting this value in equation
:
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Therefore , by Quadratic formula ,
, values of x are
. None of mentioned options are correct according to question!
<span>I think the easiest way to answer all of these is to just go ahead and find the equation of the line first.
I'm pretty sure that by the time you see this problem, you've learned how to find
the
equation of a line that passes through two given points. You have two
points: (2, 100) and (5, 205). The equation of the line through them
is
[ y = 35x + 30 ]. (That's the answer to #8.)
6). The initial membership fee ... the cost for walking in the door and signing up,
before any months, is $30. (Also the y-intercept.)
7). The cost per month is $35. (The slope of the line.)
8). We already did that, up above. [ y = 35x + 30 ].
9). 'x' in the equation is the number of months.
There are 12 months in one year.
y = 35(12) + 30 = $450</span>
Answer:
-4 / 9
Step-by-step explanation:
n - 2 = 10n + 4/2
n - 10n = 4/2 + 2
-9n = 4/2 + 4/2 ( taking LCM of 4/2 and 2)
-9n = 8/2
-9n = 4
n = 4 / -9
therefore n = -4 /9 ( since the minus sign doesn't make a difference whether placed at numerator or denominator) .
