Help I'll make you a Brainlest
melomori [17]

Answer:

x = 13

Step-by-step explanation:

m∠ABC + m∠CBD = 180°       {linear pair}

3x + 43 + 6x +  20 = 180

3x + 6x + 43 + 20 = 180

    9x  + 63           = 180

                     9x = 180 - 63

                    9x = 117

                     x = 117/9

x = 13

the function below represents the number of zombies, N, where t is the number of years since the zombies gained control of earth
raketka [301]
There is missing information about this question that I found online.
Given function is:
N(t) = 300\cdot 2^{-\frac{t}{8}}
The question is:
<span>Is this exponential growth or decay? Explain using your understanding of the properties of exponents.
</span>This is an exponential decay. 
In general, we can write down exponential functions like this:
f(x)=b^{ax}
Parameter a is the key parameter that will tell how exponential function behaves. If it is positive we have an exponential growth. If it is negative we can rewrite function like this:
f(x)=b^{-ax}=\frac{1}{b^{ax}}
We can notice that in this case, the denominator will exhibit exponential growth, in other words, the functions rapidly declines. This is an exponential decay.

The amount of money that is left in a medical savings account is expressed by the equation y= -24x+379, where x represents the n
s344n2d4d5 [400]
Y = -24x + 379

y represents money left
x represents weeks

We are finding the amount of weeks for the account to have $67 left.

Substitute y = 67

67 = -24x + 379
-312 = -24x

Divide both sides by -24 to get x by itself,

x = 13

Therefore the answer is 13 weeks!

Hope this helped!
