The answer would be 12cm because (2+4) = 6 then times that by 2 is 12

What is the answer to this please

Alex_Xolod [135]

Domain: x≤5 (notice the closed dot on the right and the arrow on the left)
Range: y≤2 (notice the closed dot on the right and the arrow on the left)

The arrow means it keeps going infinitely. The closed dot means it stops there but is inclusive of that value.

What is the inverse of function f? f(x)=10/9r+11

Rasek [7]

$f(x) = \frac{10}{9}x + 11 \\$

So :

$y = \frac{10}{9}x + 11 \\$

Subtract the sides of the equation minus 11

$y - 11 = \frac{10}{9}x \\$

Multiply the sides of the equation by 9

$9(y - 11) = 10x$

$9y - 99 = 10x$

Divided the sides of the equation by 10

$\frac{9y - 99}{10} = x \\$

So :

${f}^{ - 1}(x) = \frac{9x - 99}{10} \\$

Solve the equation log4(x + 20) = 3

salantis [7]

Answer:

Step-by-step explanation:

I don not understand what is for 4 here. So there are 2 cases:

Case 1: If you mean: log[4(x+20)]= 3

We know 3 = log(10^3)= log(1000)

So we have log[4(x+20)]= log(1000)

so 4(x+20)= 1000

and x+20 = 1000/4

x+20 = 250 and finally x= 250-20, x=230

The solution is 230.

Case 2; If you mean that 4 is the base of logarithm.

$log_{4}(x+20)= 3$

and we know that $3=log_{4}(3^{4} )= log_{4}(81)$

So we have $log_{4}(x+20)= log_{4}(81)$

and x+20 = 81

or x= 81-20

x=61

The answer is 61.

Hope that useful for you, both cases.
