X+2y greater than or equal to 10

3x-4y greater than 12

what ordered pairs are solutions to the set of equations
16,9
10,2
8,1
2,6
4,-4
14,-1
-4,2

16, 9

10, 2

Step-by-step explanation:

Given the two equations:

x + 2y ≥ 10

3x - 4y > 12

You need to multiply the first fraction by a factor of '2' in order to get the opposite coefficients of 'y' to eliminate that variable:

2(x + 2y ≥ 10)

 2x + 4y ≥ 20

+ 3x - 4y > 12

   5x > 32

    x > 6.4

Solve for 'y':

6.4 + 2y ≥ 10

2y ≥ 3.6

y ≥ 1.8

The only set of ordered pairs that have x > 6.4 and y > 1.8 are:

16, 9 and 10, 2

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
