100×20%=20mg is dissolved in one hour

20mg will be dissolved away which mean it will take 4 hours for 80mg to dissolve way

since it takes 20mg 1hour it will take 10mg half and hour or 30min to dissolve away which gives us a total of 4.5 hrs to dissolve 90mg away and leave us with 10mg

The graph of the equation y=f(x) passes through the points (-3,-5), (-2,-3),(0,1) and (4,9). What is the value of y in the equat
lapo4ka [179]
<h3>Answer:</h3>

-5

<h3>Explanation:</h3>

Each ordered pair is a list of an x-vaue and the corresponding f(x) value.

Hence the first ordered pair listed, (-3, -5), means that when x = -3, f(x) = -5. In other words, f(-3) = -5. By the transitive property of equality,

... y = f(-3) = -5

means

... y = -5

What is the value of 26+5-4*3
MatroZZZ [7]

You have to use PEMDAS (Parentheses Exponents Multiplication/Division Addition/Subtraction) to solve this,

Because you don't have any parenthesis or exponents you start with Multiplication/Division. This means you do 4*3 to get 26+5-12

Then, you move to Addition/Subtraction in which you complete left to right, So you do 26+5 to get 31-12

Finally you subtract 31-12 to get 19
