Y=x-3
(It goes down by 1x and 0 is -3)
AlekseyPX3 years ago
5 0

Answer:

y=x-3

Step-by-step explanation:

Everytime the x value increases the y value increases by 1

therefore the slope is 1

to solve for the y intercept, or b, plug in a point

(1,-2) for example,

-2= 1*1+b

-2= 1+b

b= -3

therefore y=x-3

A physician orders 140mg of a medication to give orally. You have 125mg/5mL on hand. What is the correct dose of medication to g
adelina 88 [10]
<h2>Hello!</h2>

The answer is: The correct dose of medication to give is 5.6 mL

<h2>Why?</h2>

To solve this problem we need to establish a relationship between the prescripted medication and the available solution.

Let's write the needed equations to establish the relantionship:

\frac{125mg}{5mL}=1\\\\125mg=5mL

The available solution means 125 mg each 5 mL of solution, so:

\frac{125mg}{5mL}=\frac{140mg}{x}\\\\x*\frac{125mg}{5mL}=140mg\\\\x=140mg*\frac{5ml}{125mg}=\frac{700mg*mL}{125mg}=5.6mL

Hence, the correct dose of medication to give is 5.6 mL of the 125 mg/5mL solution.

Have a nice day!

What is the greatest common factor for 60 and 45
Cerrena [4.2K]
<h3>​What is the greatest common factor for 60 and 45 ?</h3>

​<em>The greatest common factor (GCF) is also known as greatest common divisor (GCD).</em>

<em>​​First we have to find the prime factorization of 60</em>

​60 = 2² × 3 × 5

<em>​Then we have to find the prime factorization of 45</em>

​​45 = 3² × 5

<em>​Now we have to multiply the common factors to both numbers with a lower exponent</em>

​​GCF = 3 × 5 = 15

​Answer : GCF(60,45) = 15

​Hope this helps!​​​​
