Answer:
see explanation
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 6x - 2 ← is in slope- intercept form
with slope m = 6
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
, thus
y = -
x + c ← is the partial equation
To find c substitute (6, - 2 ) into the partial equation
- 2 = - 1 + c ⇒ c = - 2 + 1 = - 1
y = -
x - 1 ← equation of line
Answer: find the answer in the explanation.
Step-by-step explanation:
You are given that the sides of a rectangle are a number and 4 less than that same numbers.
Let the length side = L
And width side = L - 4
The dimensions of the rectangle will be
Area = length × width
L × ( L - 4 )
Open the bracket
L^2 - 4L
The verbal expression here,
Perimeter = L + L + W + W
Substitute all the parameters into the formula
56 = L + L + L-4 + L-4
56 = 2L + 2L - 8
56 = 4L - 8

Step-by-step explanation:
Yes the company can hire 6 carpenters and 12 pumbers
So first lets find out how much it costs to have 6 carpenter for $220 a day.
$220 × 6 = $1320 this is how much it cost to pay 6 carpenters for one day.
Now lets find how much it cost to 12 plumbers at $260 a day.
$260 × 12 = $3120 this is how much it costs to pay 12 plumbers a day.
The total amount you have to pay to the workers is:
$3120 + $1320 = $4440
Your budget was $4500 so the total costs for the workers is $4440 which means you can hire those workers and you would still have $60.
