Y-6=-6(x+5)
y-6=-6x-30
y=-6x-24 is the answer
Answer:
$4
Step-by-step explanation:
The equation for direct proportionality =
y = bx
where y = dependent variable
b = constant
x = independent variable
There is positive proportionality is two variables are positively related to each other.
In this question, price of lunches is the dependent variable while number of lunches is the independent variable
$16 = b4
Divide both sides by 4 to find b
b = $4

Let us assume base of the window = b feet.
Height is 3 feet less than base, that is = (b-3).
Given area of the triangle = 20 feet square.
We know formula for area of a triangle:
Area =
× Base × Height
Plugging values in formula, we get
20 = 




Factoring quadratic, we get
=0
b+5=0
b=-5
b-8=0
b=8.
For base we can take only positive value.
<h3>Therefore, base of the triangle = 8 feet and height = 8 -3 = 5 feet.</h3>
