Make x the subject of the formulay = mx + b​

Mathematics
2 answers:
zubka84 [21]2 years ago
6 0

Step-by-step explanation:

y=mx+c

Take c from both sides:

y-c = mx

Divide both sides by m:

(y-c) / m =x

Now swap sides to make it prettier:

x = (y-c) / m

Step-by-step explanation:

y=mx + b

•+b will move to the other side "y" changing the +ive sign to -tive

mx=y-b

°Divide both sides by m

mx/m=y-b/m

•mx/m

m cancels m leaving only x

•other side y-b/m stays the same as there's no like term that can eliminate or join together

•Answer:x=y-b/m

x =  \frac{y - b}{m}

You have to combine like terms (terms that have the same variable(x,y....) and power/exponent)²³

(4x³ - 4 + 7x) - (2x³ - x - 8)        Distribute -1 into (2x³ - x - 8)

(4x³ - 4 + 7x) + (-)2x³ - (-)x - (-)8   (two negative signs cancel each other out and become positive)

(4x³ - 4 + 7x) - 2x³ + x + 8    Now combine like terms

4x³ - 2x³ + 7x + x - 4 + 8     (I rearranged for the like terms to be next to each other)

2x³ + 8x + 4       It is equivalent to B

(-3x^2+x^4+x)+(2x^4-7+4x)       Combine like terms

-3x^2+x^4+2x^4+x+4x-7    (I rearranged for the like terms to be next to each other)

-3x^2+3x^4+5x-7    It is equivalent to D

(x² - 2x)(2x + 3)      Distribute x² into (2x + 3) and distribute -2x into (2x + 3)

(x²)2x + (x²)3 + (-2x)2x + (-2x)3

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together

2x³ + 3x² - 4x² - 6x      Combine like terms

2x³ - x² - 6x         It is equivalent to A

[Info]

When you multiply a variable with an exponent by a variable with an exponent, you add the exponents together. (You can combine the exponents only if they have the same variable)

For example:

x^{2} (x^3)=x^{(2+3)}=x^5

(y^3)x^2=y^3x^2         (You can't combine them because they have different exponents of y and x)

(5^2)(5^4)=5^{(2+4)}=5^6=15,625

What is -2x-18=-4x-6<br> need step by step
Kazeer [188]

Answer:

\boxed {x = 6}

Step-by-step explanation:

Solve for the value of x:

-2x - 18 = -4x - 6

-Take 4x and add it to -2x:

-2x - 18 + 4x = -4x + 4x  - 6

2x - 18 = -6

-Add both sides by 18:

2x - 18 + 18 = -6 + 18

2x = 12

-Divide both sides by 2:

\frac{2x}{2} = \frac{12}{2}

\boxed {x = 6}

Thus, the value of x is 6.

Which answer shows y+2&lt;4x-3, rewritten to isolate y, and it’s graph?
Natasha_Volkova [10]
To isolate y, subtract 2.
   y < 4x - 5

The graph will be a dashed line y = 4x - 5 with the area below the line shaded.
