The difference of two complementary angles is 30 degrees

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

4th option is correct xy=-10

if this was to u plzz mark me the brainliest

you can't solve x because it is 2 linear equation and you only have one equation

its the second choice.

step-by-step explanation:

the elements in the range will be 7 less than the elements in the domain.
