Answer:
<u>m</u><u> </u><u>is</u><u> </u><u>-</u><u>2</u><u> </u><u>and</u><u> </u><u>c</u><u> </u><u>is</u><u> </u><u>-</u><u>1</u>
Step-by-step explanation:
• Let's first phrase out the general equation of a line
- m is the slope
- c is the y-intercept
[ remember that a general line equation must be in slope - intercept form as shown above ]
• from our question, we are given the equation;
• let's make y the subject in order to make the equation in slope - intercept format.
→ <em>r</em><em>e</em><em>m</em><em>e</em><em>m</em><em>b</em><em>e</em><em>r</em><em> </em><em>t</em><em>o</em><em> </em><em>a</em><em>p</em><em>p</em><em>l</em><em>y</em><em> </em><em>"</em><em>s</em><em>u</em><em>b</em><em>j</em><em>e</em><em>c</em><em>t</em><em> </em><em>m</em><em>a</em><em>k</em><em>i</em><em>n</em><em>g</em><em> </em><em>k</em><em>n</em><em>o</em><em>w</em><em>l</em><em>e</em><em>d</em><em>g</em><em>e</em><em>"</em>
• The above boxed equation is now a general equation. Let's extract out slope, m and y-intercept, c
First, we determine how many months are there in two years. We know that each year has 12 months. With these, there are 24 months in 2 years. Solving for the number of crickets in two months,
f(x) = 160 x (2^24/2)
= 655,360
Therefore, after 2 years there are 655,360 crickets.
The first step is always to make an illustration of the problem. My understanding of the problem is shown in the attached picture. To make the problem easier to solve, I assumes that points C, A and D are collinear. Because if it isn't we can't find any relations that can solve the problem.
∠DAB and ∠CAB are supplementary angles. So,
∠CAB = 180 - 110 = 70°
Since a triangle has 180° altogether,
x = ∠ABC = 180 - 70 - 20 = <span>90°</span>
