Hello!

Explanation:

Distributive property: → a(b+c)=ab+ac

Expand the form equation.

$5(x-4)=5x-20$

$5x-20+3x-9x+7$

Then, simplify by equation or expand.

$5x-20+3x-9x+7=-x-13$

Final answer is: → $\boxed{=-x-13}$

<u><em>*The answer must have a negative sign.*</em></u>

Hope this helps!

Thank you :)

A taxi company charges $1.00 for the first mile (or part of a mile) and 20 cents for each succeeding tenth of a mile (or part).

meriva

Step-by-step explanation:

solving functions separately.

1st: from given data taxi charges $1.00 for the first mile.so it is first rule of function.

$y_{1} =1 , 0$

2nd: the company charge $0.20 per tenth of a mile.so 2nd rule of the function will be

$y_{2} =1+0.2.10(x-1)$

simplifying

$y_{2} =1+2(x-1)$

$y_{2} =x+2x-2$

$y_{2} =x$ , $1$

piece wise function is f(x)={2 , 0<x<1

{x , 1<x<2

the graph of the function is given below

Solve for x in triangle

fenix001 [56]

X=60degrees

bc you find 180-125 bc it is a straight angle. You get 55 degrees. Then you add 65+55=120. 180-120=60 degrees. This is because every triangle must have a sum of angles that equals 180 degrees.

Hope this helps.
