Ill give brainlist on whoever gets it right

which system of linear equations has the ordered pair (4, –5) as a solution?
2 x minus 5 y = negative 30 and 7 x + 4 y = negative 19
6 x minus y = negative 29 and 8 x + 3 y = negative 17
3 x minus 2 y = 22 and 2 x + 9 y = negative 37
5 x minus 6 y = 49 and x + 8 y = negative 27

Step-by-step explanation:

3x - 2y = 22

2x + 9y = -37

Solving this simultaneously or by elimination, x = 4

Y = -5

[4, -5]

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

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.
