Answer:

x-intercept = -9

y-intercept = -6

Step-by-step explanation:

The equation is

=> 2x+3y = -18

Finding x-intercept

Let's assume y = 0

The equation becomes

=> 2x = -18

Dividing both sides by 2

=> x = -9

Finding y-intercept:

Let's assume x = 0

The equation becomes

=> 3y = -18

Dividing both sides by 3

=> y = -6

Answer: x = -9, y = -6

y = mx + b

2x + 3y = -18

Assuming x = 0

2(0) + 3y = -18

y = -6

Assuming y = 0

2x + 3(0) = -18

x = -9

Ahab needs to mix 3.5 cups of liquid iced tea concentrate with 3 cups of water to make iced tea. Ahab has 21 cups of iced tea co

liraira [26]

Answer:

39 cups

Step-by-step explanation:

If we assume that the 3.5 cups of concentrate make 3.5+3 = 6.5 cups of tea, we can use the proportion ...

6.5/3.5 = x/21

to find the x cups of tea Ahab can make with 21 cups of concentrate.

Multiplying by 21, we get ...

x = 21(6.5/3.5) = 39

Ahab can make 39 cups of tea.

How do I solve -5x+2y=6

Olegator [25]

Answer: x = (2 y)/5 - 6/5 , y = (5 x)/2 + 3

Solve for x:
2 y - 5 x = 6
Subtract 2 y from both sides:
-5 x = 6 - 2 y
Divide both sides by -5:
Answer: x = (2 y)/5 - 6/5
Solve for y:
2 y - 5 x = 6
Add 5 x to both sides:
2 y = 5 x + 6
Divide both sides by 2:
Answer: y = (5 x)/2 + 3

What is the Area and Perimeter for tbe rectangle?

Amanda [17]

<h2>Given :-</h2>

length of rectangle = ( 4n-5 )

breadth of rectangle = ( 3n-2)

Area and perimeter of rectangle.

<h2>solution :-</h2>

by the question ,

We know the area of rectangle = length × breadth

Area = (4n -5) (3n-2)

$= {12n}^{2} - 8n - 15n + 10$

$= {12n}^{2} - 23n + 10$

now ,

perimeter = 2 ( length + breadth (

= 2 ( 4n-5 + 3n-2)

= 2 ( 7n-7)

= 14n -14

I hopes this helps.

How To Multiply Decimals And Fractions

stich3 [128]

Answer:

$\large \boxed{\mathrm{view \ explanation}}$

Step-by-step explanation:

Convert the decimal into a fraction, then multiply both fractions.

For example:

0.5 × 1/4

0.5 is also 5/10 or 1/2.

1/2 × 1/4

Multiply both fractions.

(1 × 1)/(2 × 4)

= 1/8
