The vertex of a parabola is the maximum or minimum value, and it’s represented by (x,y). The axis of symmetry is the vertical line that runs through the x axis, and also runs through the vertex. This means that the x value in the vertex (x,y) can represent the axis of symmetry.

docker41 [41]

Answer:

b  = 14-4

Step-by-step explanation:

Let the number of black bugs be b

Let the number of green bugs be g

If 14 bugs are crawling on the step, then;

b + g = 14 ....1

If there are 4 green bugs, then g = 4

Substitute g = 4 into the equation

b + g = 14

b + 4 = 14

b = 14 - 4

Hence the sentence that can be required to find the number of black bugs is b  = 14-4

timofeeve [1]

Answer:

n = 6

Step-by-step explanation:

the formula for interior angle is ( n-2)

but we given the measure of one angle, so solve

720 = (n - 2)180

720/180 = (n - 2)

4 = (n - 2)

combine the like terms

4 + 2 =n

6 = n
