2/3(x-7)=-2
2/3x-14/3=-2
2/3x=-2+14/3
2/3x=-6/3+14/3
2/3x=8/3
3/2(2/3x)=8/3(3/2)
6/6x=24/6
x=4

First you have to canceled out the fours from both side 4x/4-12/4 so x=3 then you do the same thing to the 7x-18

4x-12.
4x/4-12/4. So x=3
The fours cancelled out

7x-18
7x/7-18/7. So x= 2 4/7
The sevens cancelled out

A piece of string is 1650 cm long.
balandron [24]

Answer: The smaller piece is 750m long.

Step-by-step explanation:

let the smaller piece be x

so

150m + x + x = 1650

150 + 2x = 1650

or, 2x = 1500

so, x = 750 m

Find the area of the shaded regions. Give your answer as a completely simplified exact value in terms of π (no approximations).
Alla [95]

Area of shaded region is 18π square unit.

<u>Step-by-step explanation:</u>

Given :- A circle with center O and radius 9 cm

To Find :- area of shaded region that is area of ABC

Solution : - BC = 9 cm

∠ABC = 80° = Ф

so, area of sector = πr²Ф / 360°

= (π×9×9×80) /360°

= 18π square unit

hence, area of shaded region is 18π square unit

Find the inverse function of m(x) = 5x - 5 A m-1(x) = 5x + 5 B m-1(x) = -5x + 5 C m-1(x) = x+5/5 D m-1(x) = x+5/-5x
bogdanovich [222]
Hi there!

m(x) = 5x - 5
First replace m(x) by y.

y = 5x - 5
To find the inverse function we must switch the places from the variables x and y.

x = 5y - 5
Now we need to isolate the y again to find the formula of the inverse function. First add 5 to both sides.

x + 5 = 5y
Switch sides.

5y = x + 5
And finally divide both sides by 5.

y =  \frac{x + 5}{5}
And therefore we can conclude the following:

m {}^{ - 1} (x) =  \frac{x + 5}{5}
The answer is C.
~ Hope this helps you!
