Answer:

33250

Step-by-step explanation:

Find 1%

100% = 19000

1% = 19000 ÷ 100 = 190

100% + 75% = 175%

175% = 190 x 175 = 33250

Pls help working this out step by step:<br> Simplify fully (4+√12)(5-√3)
Airida [17]

Answer:

14 + 6\sqrt{3}

Step-by-step explanation:

(4 + \sqrt{12} )(5 - \sqrt{3} )

Each term in the second factor is multiplied by each term in the first factor

4(5 - \sqrt{3} ) + \sqrt{12} (5 - \sqrt{3} ) ← distribute parenthesis

= 20 - 4\sqrt{3} + 5\sqrt{12} - \sqrt{36}

= 20 - 4\sqrt{3} + 5(2\sqrt{3} ) - 6

= 20 - 4\sqrt{3} + 10\sqrt{3} - 6 ← collect like terms

= 14 + 6\sqrt{3}

Write The equation 3X +2 equals 4X to the second power in standard form
ale4655 [162]
3x+2=4x^2 would turn into -4x^(2)+3x+2=0 If you want X you would need to use  x=3+- sqrt (41) divided by 8.

There you go hoped I helped. :)

Find the inverse of the given function
xenn [34]

For this case, we must find the inverse of the following function:

f (x) = \frac {5x + 1} {- x + 7}\\x\neq 7

To find the inverse we follow the steps below:

y = \frac {5x + 1} {- x + 7}

We rewrite the denominator:

y = \frac {5x + 1} {- (x-7)}\\y = - \frac {5x + 1} {(x-7)}

We exchange variables:

x = - \frac{5y + 1} {(y-7)}

We solve for y:

We multiply on both sides of the equation by (y-7)

x (y-7) = - 5y-1\\xy-7x = -5y-1

We subtract xy on both sides of the equation:

-7x = -5y-1-xy

We add 1 to both sides:

-7x + 1 = -5y-xy

We factor for y:

-7x + 1 = y (-5-x)

We divide both sides by (-5-x):

y = \frac {-7x + 1} {- 5-x}

So, we have:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

Answer:

f ^ {- 1} (x) = \frac {-7x + 1} {- 5-x}

x\neq -5

6th grade math ! help me please :)
malfutka [58]
1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.

2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.

3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.

Hope this helps!!!
