All you need to do is subtract the 6 and distribute on the right side.

y + 6 = 4/5x + 2 2/5
y = 4/5x - 3 3/5

Hope this helps!!

The owner of a city parking garage uses a rate table so that he can look up the parking charges quickly. Enter a number as a dec

ioda

Answer:

Step-by-step explanation:

1.

hours 1/2 1 1.5 2 2.5 3 3.5 4

charges 3.25 6.50 9.75 13.0 16.25 19.50 22.75 26.00

2. The garage rate of parking is ;

$3.25 = 0.5 hr

?=1----------------------twice the charge for half an hour

=2*3.25=$6.50

$6.50 per hour

3.

$6.50=1 hour

$42.25=?------------------cross multiply

$(42.25*1)÷$ 6.50 = 6 hrs 30 min

It is given that 2^x = 5^y = 10^z , express z in terms of x and y

weqwewe [10]

9514 1404 393

Answer:

z = (xy)/(x+y)

Step-by-step explanation:

Taking logarithms base 10, we have ...

x·log(2) = y·log(5) = z·log(10)

z = x·log(2) = y·log(5) . . . . . . . . log(10) = 1

__

Then z/x = log(2), and z/y = log(5), so ...

z/x +z/y = log(2) +log(5) = log(2·5) = 1

z = 1/(1/x +1/y) = 1/((x+y)/(xy))

z = (xy)/(x+y)

Answer:

$f^{-1}(6) = 50$

Step-by-step explanation:

Given

$f(x) = \sqrt{2x} - 4$

Required

Find $f^{-1}(6)$

First, we calculate the inverse function

$f(x) = \sqrt{2x} - 4$

Express f(x) as y

$y = \sqrt{2x} - 4$

Swap the positions of x and y

$x = \sqrt{2y} - 4$

Solve for y: Add 4 to both sides

$4 + x = \sqrt{2y} - 4+4$

$4 + x = \sqrt{2y}$

Square both sides

$(4 + x)^2 = 2y$

Divide both sides by 2

$y = \frac{(4 + x)^2}{2}$

Express y as an inverse function

$f^{-1}(x) = \frac{(4 + x)^2}{2}$

Next, solve for: $f^{-1}(6)$

Substitute 6 for x

$f^{-1}(6) = \frac{(4 + 6)^2}{2}$

$f^{-1}(6) = \frac{(10)^2}{2}$

$f^{-1}(6) = \frac{100}{2}$

$f^{-1}(6) = 50$

3x+4(x-8)-14 evaluate for x=11

djverab [1.8K]

Answer:

For X = 11, the expression is equal to 31

Step-by-step explanation:

Hello

For X = 11 you only have to replaced the value into the expression, so:

3(11) + 4(11-8) - 14

33 + 4(3) - 14

33 + 12 - 14

31

Best regards
