How do I find out if a function is in standard form

2 answers:

4 0

A standard form is Ax+By= C
But the A can’t be a negative or a fraction so if a question gave you two coordinates (5,10)(-2,-4) to find the slope you would do change in y over x so your slope is 2 so now you know y=2x+b. After this substitute a coordinate 10=10+b so b is 0 so your equation is y=2x. To put it in standard form you move the 2x so -2x+y=0 and since Ax can’t be a negative you multiply everything by -1 to get a standard form of 2x-y=0

Hey!

A function in slope-intercept form would look like y=mx+b; with the x and y values on the opposites of the equation.

A function in standard form would look like ax+by=c; with the x and y values on the same side of the equation.

Hope this helps!

Is the following Inductive Generalization strong or weak? Apply and explain the three checks: 1. Is the appropriate group sample

arsen [322]

Answer:

For the reasons mentioned in the explanation section, it is indeed a weak generalization:

Step-by-step explanation:

No, there is not enough data provided on certain subjects' age, socioeconomic status, etc. that may have influenced the investing decision.
No, the survey isn't random, the study is irregular because each has a fair probability of expressing their true beliefs, here in this query it's written they've been told individuals are given actual medication, which may have contributed to the Hawthorne studies giving incorrect outcomes.
No, the amount isn't sufficient mostly on the premise of 28 subject areas with be provided oxytocin, and therefore only one test being performed should we not be able to determine the results to implement for certain persons including billions of populace, it would be a hurried generalization.

Abigail”s car used 9 gallons of gas to travel 378 miles. How many gallons of gas would she need to travel 210 miles?

pochemuha

Answer: 5 gallons

Step-by-step explanation:

First, we need to know how many miles we can get by on a gallon of gas. To find this, we need to divide 378 miles by 9 gallons.

378/9 = 42

42 miles per gallon.

Now, we need to find how many gallons of gas it will take Abigail to travel 210. To find this, we simply divide 210 by 42.

210/42 = 5

It will take Abigail 5 gallons of gas to travel 210 miles.

15x + 14 = 149<br><br><br>Plz solve for x

Juliette [100K]

Answer:

x = 9

Step-by-step explanation:

When doing these types of problems, the main goal is to get the variable by itself. Its kind of hard to explain with words so I will just use numbers.

15x + 14 = 149

(Subtract 14 on both sides. Remember, when you do something (Like subtracting, adding, etc.) on one side you have to do it to the other.)

15x + 14 = 149

-14 = -14

---------------------------

15x = 135

(Divide 15 on both sides. Since we need to use inverse operation to cancel the 15 out, we would divide 15 on both sides.)

15x/15 = 135/15

x = 9

Hope this helps :)
