It's was 55°f outside until the temperature increased 20°f. which number is the additive inverse of the temperature increase?

we know that

If two numbers have a sum of zero, then we say they are additive inverses

Let

x--------> the additive inverse of the increased of temperature

y-------->  the increased of temperature

we know that

---------> equation

in this problem we have

substitute the value of y in the equation

Solve for x

therefore

the answer is

the additive inverse of the temperature increase is

the graph on the bottom right

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
