Answer:

$\frac{1}{81}$

Step-by-step explanation:

Key skills: Exponents + Fractions

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as $\frac{1}{3^{4}}$

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!

Can someone finish this fast

dybincka [34]

Answer:

y + 9 = - 2(x - 9)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (9, - 9) and (x₂, y₂ ) = (- 2, 13)

m = $\frac{13+9}{-2-9}$ = $\frac{22}{-11}$ = - 2

Using (a, b ) = (9, - 9 ) , then

y - (- 9) = - 2(x - 9) , that is

y + 9 = - 2(x - 9)

The lengths of two sides of a triangle are given.

azamat

Answer:

Range = 5 - 29

Step-by-step explanation:

a + b > c

a+c > b

c+b > a

17+ 12 > c ,,,,,,,,,,,,,,,,,,,,,,,,,,,, so it should be lesser than 17+12 which is 29

17 +c > 12 ,,,,,,,,,,,,,,,,,,,,,,,,, and it should be greater than 17- 12 = 5

c+12 > 17 ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, same here, it should be greater than 17- 12 = 5

So the range is ,

17 + 12

17-12

whcih is - (5 to 29)

I hope I am right!!!

ralph is an electrician . he cgarges an initial fee of $16 plus $33 per hour if ralph earned $197 on a job how long did the job

KiRa [710]

x=#of hours worked
33 per hour or 33x (since 33 times every hour)
initial fee is independed of hours so
fee=33x+16

if fee=197 then solve for hours or x
197=33x+16
subtract 16 from both sides
181=33x
divide both sides by 33
5.4848484848=x
he worked 5.48 hours
