5 Eric is building a fence around the perimeter of a garden in his backyard. The yard is shaped like a rectangle with a width of

Elena L [17]

L=25
If the length is 25 yards then you use 50 yards of fencing for the length, this leaves ten yards for each width of fencing each.
10 yards is 15 yards less than 25 yards showing that this is the correct answer.

27^x = 9^x − 4 Question 1 options: x = 8 x = 4 x = −4 x = −8

Mariulka [41]

Answer:

x = -8

Step-by-step explanation:

Given the equation:

$27^x=9^{x-4}$

Note that

$27=3^3\\ \\9=3^2,$

then

$27^x=(3^3)^x=3^{3x}\\ \\9^{x-4}=(3^2)^{x-4}=3^{2(x-4)}$

Rewrite the equation as

$3^{3x}=3^{2(x-4)},$

then

$3x=2(x-4)\\ \\3x=2x-8\\ \\3x-2x=-8\\ \\x=-8$

What is the equation in point slope form of the line that passes through the point (−1, −3) and has a slope of 4?

blondinia [14]

Answer: y + 3 = 4 (x +1 )

Step-by-step explanation:

The eqution of a line in point- slope form is given as :

$y-y_{1}$ = m( $x-x_{1}$ )

Where m is the slope and ( $x_{1}$ , $y_{1}$ ) is the given point

substituting the values into the formula , we have:

y - (-3) = 4 ( x - {-1) )

y + 3 = 4 ( x + 1)

This is the equation of the line in point-slope form.
