A. The linear equation is: y = 60x + 45
B. The graphed equation is shown in the attachment below.
<h3>What is a Linear Equation?</h3>
A linear equation is defined as, y = mx + b, where the initial value = b; unit rate = m; x and y are the variables.
A. In this situation given, we have:
- Total cost = y
- Number of months = x
- Monthly charges = unit rate (m)= $60
- Initial value (b) = $45
Substituting the values into y = mx + b, we would have the equation as:
y = 60x + 45
B. The graph of the equation is shown in the image attached below.

Tanα=h/x, tanß=h/(x+88)
solving both for x
x=h/tanα, x=h/tanß-88, since x=x
h/tanα=h/tanß-88
h/tanß-h/tanα=88
(htanα-htanß)/(tanα*tanß)=88
h(tanα-tanß)/(tanα*tanß)=88
h=88(tanα*tanß)/(tanα-tanß)
Since α=32 and ß=22...
h=88(tan32*tan22)/(tan32-tan22)
h≈85.3 feet
Answer:
240:60 is equvilent to 15:15
Answer:

Step-by-step explanation:
Given: Browns have planted 3/16 tomatoes, 1/4 cabbage and 3/8 peppers.
First lets find out the total fraction of planted.

Now taking LCD for 16,4 and 8 to add up the fraction.
∴ LCD is 16
Next adding the fraction,

∴ Total fraction of planted gargantuas is 
Lets take the size of gragantuas as ``1``
∴ To find the un planted fraction of gargantuas.

=
=
∴ 3/16 is the unplanted fraction of gargantuas.
