What is y=3x+13 in standard form?

Answers

Answer:

3 x − y = − 13

Step-by-step explanation:

Any equation that relates the first power of x to the first power of y produces a straight line on an x-y graph. The standard form of such an equation is Ax + By + C = 0 or Ax + By = C. When you rearrange this equation to get y by itself on the left side, it takes the form y = mx +b. This is called slope intercept form because m is equal to the slope of the line, and b is the value of y when x = 0, which makes it the y-intercept. Converting from slope intercept form to standard form takes little more than basic arithmetic.

TLDR:

To convert from slope intercept form y = mx + b to standard form Ax + By + C = 0, let m = A/B, collect all terms on the left side of the equation and multiply by the denominator B to get rid of the fraction.

Answer:

3x - y = -13

Step-by-step explanation:

y = mx + b

(This is the slope intercept form)

We want to change it to standard form, which is:

Ax + By = C

We want to rearrange as many of the numbers as we can, without actually changing the problem!

Ax = 3x

By = y

C = 13

So we must move the numbers from one side to another.

Whatever you do to one side, you do to the other.

y = 3x + 13

-3x + y = -3x - y

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

-3x + y = 13

Since we can't have our "Ax" as a negative multiply everything by -1

-1[-3x + y = 13]

3x - y = -13

That is your answer.

21y - 1 = 4x + 23

21y - 24 = 4x

5.25y - 6 = x

21y - 1 = 4x + 23

21y = 4x + 24

y = 4/21(5.25 - 6) + 1.14

y = 1 - 1.14 + 1.14

y = 1

5.25(1) - 6 = x

Answers

Answer:

61

Step-by-step explanation:

hi! we can start off by plugging in the number 9 for x in the equation.

f(x)=8x-11)

f(9)= 8(9)-11

= 72-11

=61

hope this helps.

The answer is 61.

Replace the x in the equation with the nine. F(9) = 8(9) - 11

Now first multiply 8 x 9 which is 72

Now you have F(9) = 72 - 11
Subtract the two numbers.

F(9) = 61

the amount of money rachel earns varies directly with the number of hours she works. if sue earns $600 when she works 40 hours , how much will she earn for working 85 hours ?

Answers

Answer:

I think 500

Step-by-step explanation:

600 minus 40 mminus 85

1,275
Explanation : If she earns 600 dollars working for 40 hours, you can find the amount she earns working an hour by dividing 600/40 which will give you $15 an hour. From there it asks how much will she earn working 85 hours, so you multiply $15 by the 85 hours so you get 1,275

Step-by-step explanation: just took it

Function [tex]y=cos2(x)-2[/tex] and function [tex]y=cos(x)-3[/tex].

Function:A function in mathematics from a set [tex]x[/tex] to a set [tex]y[/tex] allocates exactly one element  [tex]y[/tex] to each element [tex]x[/tex]. The sets [tex]x[/tex] and [tex]y[/tex] are collectively referred to as the function's domain and codomain, respectively.Initially, functions represented the idealized relationship between two changing quantities. A planet's position, for instance, depends on time. In the past, the idea was developed with the infinitesimal calculus at the end of the 17th century, and the functions that were taken into consideration until the 19th century were differentiable (that is, they had a high degree of regularity).Solution -

The function which has the same amplitude as the function [tex]y=cos(x-4)+1[/tex] and is the translation of the parent cosine is as follows:

Answer:  35 degrees

Explanation: Luis forgot to subtract the value of each arm of the angle. So he should have done 80-45 = 35. The answer would be 80 degrees if arm TQ was at 0 degrees (so 80-0 = 80), but instead TQ is at 45 degrees.
