The sum of two consecutive whole numbers is
91. What are the numbers?

Represent your numbers as follows.

X ⇒ first number

X + 1 ⇒ second number

Since their sum is 91, we have x + (x + 1) = 91.

Solving from here, simplify on the left side to get 2x + 1 = 91.

Subtract 1 from both sides to get 2x = 90.

Now divide both sides by 2 and x = 45.

So if x = 45, then x + 1 must be 46.

So our numbers are 45 and 46.

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)

i think that you should ask google for the answer to that problem because if we don't know it google does
