Which of the following ordered pairs represents a solution to the linear inequality y>2x-3?

Mathematics
1 answer:
devlian [24]3 years ago
7 0

Answer:

B (2, 5).

Step-by-step explanation:

Y is greater than 2x-3.

Check each one in turn:

A. (4,4) ;  y = <u>4</u><u> </u>and 2x-3 = 2(4)-3 =<u> 5.</u> NOT a solution ( y<2x-3 in this case).

B. (2, 5): y = 5 and 2x - 3 = 2(2) - 3 = 1   so y>2x-3 and this point IS a solution.

C. (3, 2)  y = 2 and  2x-3 = 3 - NOT a solution.

D. (9, 12) y = 12 and 2x-3 = 15 - Not a solution.

astraxan [27]

Answer:

Step-by-step explanation:

STEPS FOR SOLVING LINEAR EQUATION

3y=4x+1

Swap sides so that all variable terms are on the left hand side.

4x+1=3y

Subtract 1 from both sides.

4x=3y−1

Divide both sides by 4.

Dividing by 4 undoes the multiplication by 4.

in the equation x+3y=6, suppose the x-intercept was at (m,0) and the y- intercept was at the ordered pair (0,n). what is the val
VMariaS [17]

Answer:

8

Step-by-step explanation:

The x intercept is when y = 0

x + 3(0) = 6

x = 6

So (6,0) and m = 6

the y intercept is when x = 0

0 + 3y = 6    Divide by 3

y = 6/3

y = 2

the y intercept is (0,2) and n = 2

Answer

m + n = 6 + 2 = 8

The water at the end of a pier was 28 meters deep at midnight. As the tide came in, the water depth increased at a rate of 0.012
Nastasia [14]

Answer:

  0.012t + 28 = 30

Step-by-step explanation:

The depth starts at 28 meters. The amount of increase in t minutes will be 0.012t, so the total depth after t minutes is ...

  0.012t +28

We want to find when that is equal to 30, so the appropriate equation is ...

  0.012t +28 = 30

astronomers measure large distances in light years one light year is the distance that light can travel in one year or approxima
sveticcg [70]
What you can do in this case is the following rule of three to find the result:
 1 light year ---> 5.88 * 10 ^ 12 miles
 3.2 * 10 ^ 2 light year ---> x
 Clearing x we have:
 x = ((3.2 * 10 ^ 2) / (1)) * (5.88 * 10 ^ 12)
 x = 1.88 * 10 ^ 15 miles
 answer:
 In scientific notation, approximately it is 1.88 * 10 ^ 15 miles
