After subtracting 2x from each side, the resulting equation is shown below:
2x+4y=8
4y=-2x+8
the final step to solve for y would be to what?

Answer:

Rational numbers refers to a number that can be expressed in a ratio of two integers. An irrational number is one which can't be written as a ratio of two integers. Expressed in fraction, where denominator ≠ 0. Cannot be expressed in fraction.

Step-by-step explanation:

done

Answer:

the answer is F: 6 because you add all the numbers together and then divide by the amount of numbers in the problem

Step-by-step explanation:

Answer:

6 is the answer cause when you add it all up it equals 60 then divide by how many numbers there were and that was 10 numbers so 60÷10=6

Answer: 6 inches

Step-by-step explanation:

Road in inches = 1 ⁴/₅

Road in miles = 1 ¹/₅

Inches per mile = 1 ⁴/₅ / 1 ¹/₅

= 1.5 inches

If the road is 4 miles long, on the map it would be;

= 1.5 * 4

= 6 inches

Answer:

4 × (3 + 7) = (4 ×7) + (4 × 3)

Step-by-step explanation:

If you go by the order of PEMDAS you would do the parentheses first. 3 + 7 =10. 10 × 4 = 40. Then you would just use the distributive property and do (4× 7) + (4 × 3)

4 × 7 = 28 and 4 × 3 = 12 28 +12 =40

Answer:

x-intercept is 50        y-intercept is 40

y+3=-5(x-8)

Step-by-step explanation:

Answer:

a^2+b^2=c^2

c=15 units

Step-by-step explanation:

You can use the pythagorean theorem to solve this equation. a^2+b^2=c^2.

If you substitute the leg lengths in, the new equation will be 9^2+12^2=c^2, c being the hypotenuse.

Next, you can simplify it to get 81+144=c^2. Simplifying it further, you get 225=c^2, which means that the length of the hypotenuse is 15. Hope this helped! :)

Answer:

15

Step-by-step explanation:

9^2+12^2=c^2

81+144=c^2

225=c^2

15=c

or you can see that this is a 3,4,5 triangle (just 3 times bigger)

hope this helps :)

Answer:

2.84 minutes

Step-by-step explanation:

Subtract the less time of Ana from the intial (Beth) then subtract the amount less of Fran

4.59 - 0.7 = 3.89 minutes

3.89-1.05 = 2.84 minutes

Answer: LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOL FAT NECK AHH BOY

Answer:

she took 13 classes that were worth 3 credits

Step-by-step explanation:

well we know that some of the classes are worth 3 and some are worth 4 and that all of these together = 59 so your first equation would be

3x+4y=59

x  would be the number of classes worth 3 credits and y would be the number of classes worth 4 credits.

then it says the total number of classes that they took was 18 so we know that

x + y =18.

you want to solve for the number of 3 credit classes so lets go ahead and get rid of the y values. SO you need you multiply the x+y equation by 4

4x+4y=72

then subtract 4x+4y=72  from 3x+4y=59 to get

-x = -13

and then x is a negative so you need to divide -1 from both sides and you get that she took 13 classes that were worth 3 credits.

Answer:

4 = 256.

Step-by-step explanation:

The formula used in each equation is 4x = Y. So, 41 = 4, 42 = 16, 43 = 64, and 44 = 256.

Answer:

[tex]\huge\boxed{\sf 256}[/tex]

Step-by-step explanation:

The equation used for this unfinished equation is:

[tex]\sf 4^{x} = y\\\\Where \ x \ is \ L.H.S \ and \ y \ is \ R.H.S[/tex]

So,

If x = 1, y = 4

[tex]\sf 4^1 = 4[/tex]

If x = 4 , y = 256

[tex]\sf 4^4 = 256[/tex]

[tex]\rule[225]{225}{2}[/tex]

Answer:

300

Step-by-step explanation:

Answer:

x = 2

Step-by-step explanation:

g(x) = 2x - 1

g(x) = 3

2x - 1 = 3

Add 1 to both sides;

2x = 4

Divide both sides by 2;

x = 2

Answer:

(f · g)(x) = 4x³ + x² - 20x - 5

General Formulas and Concepts:

Pre-Algebra

Algebra I

Step-by-step explanation:

Step 1: Define

f(x) = 4x + 1

g(x) = x² - 5

(f · g)(x) is f(x)g(x)

Step 2: Find (f · g)(x)

We know that,

[tex] \Large \underline{\boxed{\sf{ (f . g)(x) = f(x) \times g(x) }}}[/tex]

By substituting values :

[tex] \sf : \implies (f . g)(x) = (4x+1) \times (x^{2} -5)[/tex]

[tex] \sf : \implies (f . g)(x) = 4x(x^{2} -5) +1(x^{2} -5)[/tex]

[tex] \sf : \implies (f . g)(x) = 4x^{3} - 20x + x^{2} -5[/tex]

[tex] \sf : \implies (f . g)(x) = 4x^{3} + x^{2} - 20x -5[/tex]

Hence, answer is :

[tex]\underline{\boxed{\sf{(f . g)(x) = 4x^{3} + x^{2} - 20x - 5}}}[/tex]

Answer:

Hello,

In order to determine which is the horizontal asymptote remember that the horizontal is always x= something and remember that horizontal is straight from left to right.

So Horizontal asymptote = 2

For vertical asymptote it goes from the bottom of the graph, directly up. Think about it like this, you stand upright...or vertically right? So the vertical asymptote is

y= 0

Step-by-step explanation:

x - 3y = 6

3y = x - 6

y = 1/3 x - 2.

Here m is 1/3 and b is -2.
