100 POINTS (urgent) Write an equation of a line that passes through the point (2, 3) and is parallel to the line y =3/2X + 5
DIA [1.3K]

Answer:

C.  3/2x

Step-by-step explanation:

Firstly, we know that the slopes are the same because parallel lines have the same slope. Then we can find the y-intercept by using the slope and point in slope-intercept form.  

y = mx + b ---> plug in known values

3 = (3/2)(2) + b ---> Multiply

3 = 3 + b ---> Subtract 3 from both sides.  

0 = b

Since the intercept is 0, you will not see a number after the slope and x.

The temperature in Greenland is -8.3°C. The temperature in Jamaica is 30°C. What is the difference between the temperatures in t
Fantom [35]

Answer:

The difference between the temperatures in the two countries is 38.3°C.

Step-by-step explanation:

Given:

Temperature in Greenland = - 8.3°C

Temperature in Jamaica = 30°C

To find :

The difference between the temperature in the two countries = ?

\textrm{difference between the temperature in the two countries} =\textrm{temperature in Jamaica} - \textrm{temperature in Greenland}\\= 30 - (-8.3)\\= 30 +8.3\\= 38.3\°C

Therefore,the difference between the temperatures in the two countries is 38.3°C

Pleaseeee help<br> solve for x and y
iogann1982 [59]

Answer:

Solution given:

y+135°=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]

y=180°-135°

y=25°

again

2x-1+3x+1=180°[sum of opposite angle of a cyclic quadrilateral is supplementary]

5x=180

x=180/5.x=36

<u>x</u><u>=</u><u>3</u><u>6</u><u>°</u><u>,</u><u>y</u><u>=</u><u>2</u><u>5</u><u>°</u>

Y is inversely proportional to V1+x.<br> When x = 8, y = 2.<br> Find y when x = 15.
murzikaleks [220]

Answer:

y = 1.5

Step-by-step explanation:

Given x is inversely proportional to \sqrt{1+x} , then the equation relating them is

y = \frac{k}{\sqrt{1+x} } ← k is the constant of proportion

To find k use the condition when x = 8, y = 2

2 = \frac{k}{\sqrt{1+8} } = \frac{k}{\sqrt{9} } = \frac{k}{3} ( multiply both sides by 3 )

6 = k

y = \frac{6}{\sqrt{1+x} } ← equation of proportion

When x = 15 , then

y = \frac{6}{\sqrt{1+15} } = \frac{6}{\sqrt{16} } = \frac{6}{4} = \frac{3}{2} = 1.5
