The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle
solve
115+z=180
subtract 115 from boths ides
z=65
answer is third angle=65 degrees
Answer:
(b) (18, 27), because the rate of change of the function is 4/3
hope this helps!
Step-by-step explanation:
B, C and D are exponential decay.
Half-lives are given by exponential function, and since they are decreasing, it is decay.
With the teams being eliminated, this is decay.
Bacteria can be represented by exponential functions, and it is decreasing.
Answer:
M= -2
B=1
Step-by-step explanation:
<u><em>Y-intercept</em></u><em> is the point where the line crosses through the y line, so you can clearly see that that point is (0,1) we only write the y value because for a y intercept the x value will always be zero</em>
<em><u>Slope</u></em> <em>is the rise over run, meaning how much the y value changes over how much the x value changes, so for the two points we use our formula:</em>

<em>So now input how much it changes by adding the numbers from each coordinate:</em>

<u>Simplify:</u>
<u />
<u />
<em>But we write it as:</em>
-4/2
<em>This is because this looks more like division</em>
<u>Divide:</u>
-4/2=-2
So, your slope is <em><u>-2</u></em> and the y- intercept is <em><u>1</u></em>
I hope this helps u pls give a brainliest and a thx ;)
