Answer:

n=3 5/7

Step-by-step explanation:

8(n+7) Multiply each term in the parenthesis by 8

8n + 8 x 7

8n + 56

4 - 6n = 8n + 56

move variable to the left by adding its opposite to both sides

-6n - 8n + 4 = 8n - 8n +56

eliminate the opposites

-6n - 8n + 4 = 56

collect like terms by calculating the sum or difference of their coefficients

-6n - 8n

(-6 - 8)n

calculate the difference

-14n

divide both sides of the equation by -14

-14n / (-14) = 52 / (-14)

n = 52 / (-14)

n = -52/14

n= -26/7

alternative form of writing the answer is

n= -3 5/7 or n= 3.71429

How to do this question plz answer me step by step plzz plz

Iteru [2.4K]

Answer:

£13496.80

Step-by-step explanation:

We can ignore the £ sign for now, that is just units.

If we decrease a number by 4.5%, we will have to find $100-4.5=95.5$ % of 14132.77.

We can easily do this by setting up a proportion.

$\frac{x}{14132.77} = \frac{95.5}{100}$

Multiply 14132.77 by 95.5:

$14132.77\cdot95.5=1349679.535$

Divide by 100:

$1349679.535\div100=13496.79535$

Rounding this to two decimal places, it simplifies to 13496.80.

Hope this helped!

Write the equation of the line in slope-intercept form using y=mx+b

Phoenix [80]

Answer:

y=-4/6+2

Step-by-step explanation:

The rise is -4, and the run is 6. Rise over run means that the slope is -4/6. the Y intercept is 2. Therefore y=-4/6+2.

If you shift the quadratic parent function, f(x) = x2, left 12 units, what is the equation of the new function? A.g(x) = (x + 12

timama [110]

Answer: The correct option is (A). $g(x)=(x+12)^2.$

Step-by-step explanation: Given that the equation of the quadratic parent function is

$f(x)=x^2~~~~~~~~~~~~~~~~~~~~~~~~``(i)$

We are to find the equation of the new function after shifting the parent function (i) 12 units left.

Since we are shifting 12 units left, so there is a horizontal translation in the X-axis.

And the x co-ordinate becomes (x+12).

Therefore, the equation of the new function will be

$g(x)=(x+12)^2.$

Thus, the required equation of the new function is $g(x)=(x+12)^2.$

Option (A) is correct.
