Answer:

\Huge \boxed{x=3}

Step-by-step explanation:

7(2-2x)= -13-5x

Expanding brackets.

14-14x= -13-5x

Adding 5x and -14 to both sides.

-14x+5x=-13-14

-9x=-27

Dividing both sides by -9.

x=3

Answer:

x=3

Step-by-step explanation:

We can try and isolate x on one side of the equation to find its value.

First let's apply the distributive property on the left side and get a simpler equation.

7(2-2x)=-13-5x\\\\14-14x = -13-5x

Now, to simplify this down, we can add 5x to both sides.

14-14x + 5x = -13-5x + 5x\\\\14-9x=-13

Now we can add 13 to both sides:

14-9x+13=-13+13\\\\27-9x=0

Now we subtract 27 from both sides:

27-9x-27=0-27\\\\-9x=-27

And finally we divide both sides by -9.

-9x\div-9=-27\div-9\\\\x=3

Hope this helped!

It is known that 1.4< square root of 2 <1.5. Find all possible values of the expression 2-square root of 2. How do I find
horsena [70]

Answer:

0.5<2-√2<0.6

Step-by-step explanation:

The original inequality states that 1.4<√2<1.5

For the second inequality, you can think of 2-√2 as 2+(-√2).

Because of the "properties of inequalities", we know that when a positive inequality is being turned into a negative, the numbers need to swap and become negative. So, the original inequality becomes -1.5<-√2<-1.4. (Notice how the √2 becomes negative, too). This makes sense because -1.5 is less than -1.4.

Using our new inequality, we can solve the problem. Instead of 2+(-√2), we are going to switch "-√2" with both possibilities of -1.5 and -1.6. For -1.5, we would get 2+(-1.5), or 0.5. For -1.4, we would get 2+(-1.4), or 0.6.

Now, we insert the new numbers into the equation _<2-√2<_. The 0.5 would take the original equation's "1.4" place, and 0.6 would take 1.5's. In the end, you'd get 0.5<2-√2<0.6. All possible values of 2-√2 would be between 0.5 and 0.6.

Hope this helped!

Find f(x)=x^2-x^3,find f(-10)
Elanso [62]

Answer:

Value of f(-10) is 1100

Step-by-step explanation:

Given that f(x) = x² - x³

Here we need to find f(-10).

 f(-10) =  (-10)² - (-10)³

 f(-10) = 100 - (-1000)

 f(-10) = 100 + 1000

 f(-10) = 1100

Value of f(-10) is 1100

Write an equation for the nth term of the geometric sequence. Then find the 7th term. 2,-6,18,-54,...
Sonja [21]

soln,

from the series,

a = 2

t2 = -6

r = t2/a

=   \frac{ - 6}{2}

= -3

therefore, tn =

{ar}^{n - 1}

=  {2 \times  - 3}^{n - 1}

now,

seventh term =

{2 \times  - 3}^{7 - 1}

=  {2 \times  - 3}^{6}

= 2 \times 729

= 1458
