write the equation of the line that passes through the points (3,1) and (-2,6) in slope intercept form

Answers

Answer:

y = - x + 4

Step-by-step explanation:

First find slope:

6-1/-2-3 = 5/-5 = -1

Then plug one point and slope into point slope form: y-y1 = k (x-x1)

Plug in (3, 1) and slope -1 --> y-1 = -1(x-3)

Simplify --> y - 1 = - x + 4

Then add 1 to both sides --> y = -x + 4

Mixed Number: 5 [tex]\frac{7}{10}[/tex]

Improper Fraction:[tex]\frac{57}{10}[/tex]

Step-by-step explanation:

A mixed number is when you express the decimal as a fraction, 0.7 is the same as [tex]\frac{7}{10}[/tex], so 5[tex]\frac{7}{10}[/tex] is your answer.

An improper fraction is a fraction where the numerator is bigger than the denominator, to do this you multipy the whole number 5, which can be written as [tex]\frac{5}{1}[/tex], by [tex]\frac{10}{10}[/tex].

[tex]\frac{5}{1}[/tex]·[tex]\frac{10}{10}[/tex]=[tex]\frac{50}{10}[/tex]

Then add 0.7, or [tex]\frac{7}{10}[/tex].

[tex]\frac{50}{10}[/tex]+[tex]\frac{7}{10}[/tex]=[tex]\frac{57}{10}[/tex]

X is 2 because 10 x 2 equals 20 -3 equals 17

Answer:

x=2

Step-by-step explanation:

To solve for x, you want to isolate it. To do this, move terms that are NOT x and use the opposite operation to get it to the other side.

10x - 3 = 17

(Add 3 to both sides)

10x = 20

Now isolate x (since 10x is really 10 * x, you divide)

10x=20

x=2

This is how you would solve to get the solution.

Given f(x)=2x+1 and g(x)=7-x. Find g(f(x)).

Answers

Answer:

f(g(x)) = 2(7 - x) + 1

Step-by-step explanation:

f(x) = 2x + 1

g(x) = 7 - x

The question in the picture itself says to find f(g(x)) so i'll find that instead

f(g(x)) = 2(7 - x) + 1

f(g(x)) = 14 - 2x + 1

f(g(x)) = -2x + 15

Can anyone help me with this please I really need help with this rq .

Answers

Answer:

Step-by-step explanation:

g(x) = ax - b

-76 = 27a - b

-79 = 28a - b           Subtract

3 = -a                       Multiply both sides by  -1

a = -3

g(x) = -3x - b

-85 = -3*30 - b

-85 = - 90 - b          Add 90 to both sides

90-85 = - b             Combine

5 = - b                     Multiply both sides by - 1

-5 = b

g(x) = -3x - b

g(x) = -3x - (-5)

g(x) = - 3x + 5

If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost

Answers

Answer:

$28.42

Step-by-step explanation:

First let's calculate the cost per gallon.

We can do this by simply dividing the cost of 4 gallons by 4

1 gallon of milk cost 16.24/4 = 4.06

We want to find the cost of 7 gallons.

We can easily do this by multiplying the cost of one gallon by 7

7 gallons of milk cost 7 * 4.06 = $28.42

Factor. Check by multiplying.

What is the equation of the line in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

[tex]y=-\frac{1}{4}x\\[/tex]

Step-by-step explanation:

The slope is calculated by "up ÷ across".

= -1 ÷ 4

= [tex]-\frac{1}{4}[/tex]

The y-intercept is just 0 (because the line meets at the y axis at 0).

So, using [tex]y=mx+b[/tex] (where m = slope and b = y-intercept),

[tex]y=-\frac{1}{4}x+0[/tex]

but the '+0' is unnecessary so we just say [tex]y=-\frac{1}{4}x[/tex]

And to be clear, I don't mean adding a single note to a song and then calling it a new song, or changing a single note's pitch so slightly that it's beyond human hearing and calling it a new song, but really, with the limited amount of notations on a piano, can you make new songs, something that doesn't exist and has a completely new feel to it? And do you think you can do this over and over again endless amounts of times and if I had written trillions upon trillions upon trillions of piano pieces, could I make each and every one of them unique and special as opposed to the others? Even if you were to make a calculation and presume that a 10-note melody had 85 quintillion combinations on a modern 88 key piano, and then another calculation that told you how many chord progressions were possible in that 10-note melody, and both the melody and chord progression combinations were so vastly gigantic in numbers that you couldn't type it out within any amount of years, is it still finite? IS there still only a limited amount of musical ideas where one day we will have made every possible unique song? This is something iv'e had an existential crisis about as a want to be musician.
