Change -3x+3y=9 into slope intercept form

Answers

To convert to slope-intercept form, we need to get the y by itself.

First add 3x to both sides to get 3y = 3x + 9.

I put the x term first because in slope-intercept form or y = mx + b form,

the x term will always come before the constant term.

Now divide both sides by 3 to get y = x + 3.

Answer:

y = x + 3

Step-by-step explanation:

-3x + 3y = 9

3y = 9 - 3x

/3     /3   /3

y = x + 3

i need < 2 and <4 help plz

Answers

Answer:

Step-by-step explanation:

m<3 = 43 degrees

add 43 degrees and 43 degrees and the answer is 86. and since everything equals 180 degrees, 180 - 86 = 94. since there are 2 side needed to be solved divide 94/2 = 47

so 47 degrees for <2 and 47 degrees for <4

to check my work just add up all the sides

47 degrees for <2, 47 degrees for <4, 43 degrees for <1, 43 degrees for <3

47 + 47+ 43+ 43= 180 degrees

Diego bought some raisins and walnuts to make trail mix. Raisins cost $4 a
pound and walnuts cost $8 a pound. Diego spent $30 on both ingredients.
Write an equation to represent this constraint. Let x be pounds of raisins
and y be pounds of walnuts.

Answers

Answer:

4x + 8y = 30

Step-by-step explanation:

Cost of raisins = $4 per pounds

Cost of walnuts = $8 per pounds

Total spent on both ingredients = $30

Let

Pounds of raisins = x

Pounds of walnuts = y

Diego's equation can be represented by

PxQx + PyQy = 30

Where,

Px = price of raisins

Qx = Quantity of raisins (pounds)

Py = price of walnuts

Qy = Quantity of walnuts (pounds)

PxQx + PyQy = 30

4x + 8y = 30

Which expression is equivalent to 1.8(2x + 7) - 15?
a 1.2x
b 3.6x - 2.4
0 3.6x - 8
d 16.2x - 15

Answers

Answer:

Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4

Step-by-step explanation:

1.8(2x + 7) – 15

To know which option is correct, let us simplify the above expression. This can be obtained as follow:

1.8(2x + 7) – 15

Clear bracket

1.8(2x + 7) – 15 = 3.6x + 12.6 – 15

1.8(2x + 7) – 15 = 3.6x – 2.4

Thus,

1.8(2x + 7) – 15 is equivalent to

Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.

Answers

Answer:

-3

Step-by-step explanation:

Given numbers:

1/6, -3, √7, -6/5, 4.5

The smallest one is chosen between the two negatives as all the rest are greater.

- 3 is smaller than - 6/5= -1.2 as 3 > 1.2

So the answer is -3

Greetings from Brasil...

Let's look at each number

1/6 = 1 ÷ 6 = 0.16666....

- 3 = - 3

√7:

√4 < √7 < √9, so

2 < √7 < 3   the result of √7 is between 2 and 3

-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2

4.5 = 4.5

Writing the numbers in ascending order can tell:

- 3; - 6/5; 1/6; √7 and 4.5

or (same values - approximated values):

- 3; - 1.2; 0.2; 2.5 and 4.5

Step-by-step explanation:

First you need to place the exponent on both the numerator and the demonimator to make 3 to the power of 3 over 7 to the power of 3

Next you evaluate the numerator so 3 to the power of 3 is 27

and 7 to the power of 3 is 343 so your answer in fraction form is 27/343

you can also change into a decimal if you divide the fraction if you need to
