Answer:

x = -2/4

Step-by-step explanation:

You always want to leave the variable alone-

-4x + 7 = 9

To do that you need to get rid of the seven and that can be done by subtracting/adding it by its opposite value in both sides of the equation.

-4x = 2

Get rid of that 4 by dividing from both sides of the equation-

x = -2/4

Answer:

x= -1/2

Step-by-step explanation:

Mkay... You would start off by getting rid of the parentheses because they aren't needed here...

7 - 4x = 9

Now, you would add 4x to both sides to get rid of the subtraction...

7 = 9 + 4x

Then, you subtract 7 from each side....

0 = 2 + 4x

Moving on, you would subtract 2 from each side...

-2 = 4x

And then divide 4 on each side to get...

x = -1/2

And there's your answer!

The price of a cycle is reduced by 25 per cent. The new price is reduced by a further 20 per cent.Find the single reduction the
Evgen [1.6K]

Answer:

40%  . The single reduction together is 40%.

Step-by-step explanation:

Let the bicycle cost is   x before reduced price.

First 25% is reduced  and again 20% further reduced.

Let the single reduction is y% if the two reduction together are equal.

Solution,

Case .1

reduction cost=x\times 25%%

=x\times 25/100

=x/4

The cost of bicycle after reduction of 25% is

=x-x/4=3x/4

cost of reduction further reduction of 20%      =3x/4\times 20%

=3x\times 20/(4\times 100)

=3x/20

The new cost of bicycle is further reduction of 20% is

=3x/4-3x/20

=\left ( 15x-3x \right )/20

=12x/20=3x/5

Case.2

if single reduction is done new cost of cycle is equal

x-x\times y%=3x/5

x\left ( 1-y/100 \right )=3x/5

\left ( 100-y \right )/100=3/5

100-y=60

y=40%

single reduction of a cycle is 40%

According to the rational root theorem, what are all the potential rational roots of f(x)= 5x^3-7x+11
Tems11 [23]

The rational root theorem states that the rational roots of a polynomial can only be in the form p/q, where p divides the constant term, and q divides the leading term.

In your case, both the leading term 5 and the constant term 11 are primes, so their only divisors are 1 and themselves.

So, the only feasible solutions are

\pm\dfrac{11}{5},\quad\pm 11,\quad \pm\dfrac{1}{5}, \pm 1

For the record, in this case, none of the feasible solutions are actually a root of the polynomial.

Identify the Asymptotes for the graphs below help pls!
scoray [572]
Asymptotes are lines that continues to approach a given curve but never actually meets it! For the second figure it is the Y axis since the curves slowly appear to approach the Y axis! Not sure about the first figure(probably the X axis)!
