Put this equation into slope- intercept form. -2x + 3y = 9

Answers

Answer:

y = 2/3x + 3

Step-by-step explanation:

In order to put it in slope intercept form (y = mx + b), y needs to be isolated.

Add 2x to both sides:

-2x + 3y = 9

3y = 2x + 9

Then, divide both sides of the equation by 3.

3y = 2x + 9

y = 2/3x + 3 is the equation in slope intercept form

Answer:

Slope-intercept form:

→ y = (2/3)x + 3

Step-by-step explanation:

Given equation,

→ -2x + 3y = 9

Now we have to,

→ Convert this given equation into the slope-intercept form.

The slope-intercept form is,

→ y = mx + b

Let's convert the equation,

→ -2x + 3y = 9

→ 3y = 9 + 2x

→ 3y = 2x + 9

→ y = (2x + 9)/3

→ y = (2x/3) + (9/3)

→ y = (2/3)x + 3

From this slope-intercept form:

→ Slope (m) = 2/3

→ y-intercept (b) = 3

Thus, the answer is y = (2/3)x + 3.

-16+2x= -64 what is the value of x

Answers

Answer:

add 16 to both sides so it would 2x=-48 then you would divide 2 on both sides so it would be x=-24

Step-by-step explanation:

X=-24

Answer:

-16 + 2x = -64

+16 +16

2x = -48

-48÷2=-24

x = -24

Jefferson Middle School needs to see a 300% gain in PTO fundraiser
sales from last year. If they sold a total of $2,420 last year, how much do
they need to sell this year to meet their goal? *

Answers

Given parameters:

Percentage gain = 300%

Selling cost last year = $2420

Unknown:

Selling cost this year = ?

Solution:

To solve this problem;

Profit percent = [tex]\frac{Selling cost this year - Selling cost last year}{Selling cost last year} x 100[/tex]

300 = [tex]\frac{S - 2420}{2420} x 100[/tex]

3 = [tex]\frac{S - 2420}{2420}[/tex]

S- 2420 = 7260

S = $9680

To make a 300% gain, Jefferson Middle school needs a $9680 from fundraiser sales this year.

Answer:

908.563 in²

Step-by-step explanation:

see attached image

A1 = 12 x 34 = 408

A2 = h = √(34² - 17²) = 29.445

= (1/2 * 34 * 29.445)

= 500.563

total area = A1 + A2

= 408 + 500.563

= 908.563 in²
