Solve -5√x=-15 hurry
a. x=9
b. x=7
c. x=-7
d. x=-9

-5 √x = -15

to isolate x you must first divide -5 to both sides. since -5 is being multiplied by √x, division (the opposite of multiplication) will cancel -5 out (in this case it will make -5 one) from the left side and bring it over to the right side.

=

= 3

to solve this you must get rid of the square root. the opposite of square root is square. you must square both sides since what you do to one side you must do to the other.

()² = 3²

a. x = 9

hope this !

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)
