Which expression is equivalent to 2^4 ⋅ 2^−7?

yaroslaw [1]

Remember
$(x^m)(x^n)=x^{m+n}$
and
$x^{-m}=\frac{1}{x^m}$

so
$(2^4)(2^{-7})=$
$2^{4-7}=$
$2^{-3}=$
$\frac{1}{2^3}=$
$\frac{1}{8}$

The health club is raising money through a babysitting fundraiser. On Thursday, they charged $3 per hour plus an initial fee $40

xeze [42]

They need to babysit for 10 hours to have same money each day.

Step-by-step explanation:

On Thursday;

Charges = $3 per hour

Initial fee = $40

let x be the number of hours.

T(x) = 3x+40

On Friday;

Charges = $4 per hour

Initial fee = $30

F(x)= 4x+30

The cost will be same when;

T(x) = F(x)

$3x+40=4x+30\\40-30=4x-3x\\10=x\\x=10$

They need to babysit for 10 hours to have same money each day.
