20 | 6



ab = 2 * 6 = 12

4b/2 = (4 * 6) / 2 = 24 / 2 = 12

a^3 + 2b = 2^3 + 2 * 6 = 8 + 2 * 6 = 8 + 12 = 20

b^2 / (4 + a) = 6^2 / (4 + 2) = 6^2 / 6 = 36 / 6 = 6

Find the slope of the line passing through the two points.<br><br> (2.1, 3.8), (3.1, 7.6)
bixtya [17]

Answer:

3.8

Step-by-step explanation:

Slope formula- m = y2 - y1            

                                x2 - x1      

x1, y1

2.1, 3.8

                                   7.6 - 3.8

                                    3.1 - 2.1   =   3.8

Complete the square than convert to vertex form. y=2x^2+8x-9​
8_murik_8 [283]

y=2x^2+8x-9\\D=b^2-4ac\\D=64-4(2)(-9)\\D=64+72 > 0

There are 2 roots so the only way to complete the square is,

y=2x^2+8x-9\\y=2[(x^2+4x)]-9\\y=2[(x^2+4x+4)-4]-9\\y=2[(x+2)^2-4]-9\\y=2(x+2)^2-8-9\\y=2(x+2)^2-17

Just factor 2 out of 2x^2+8x (just ignore the -9) then find the number that will make the terms be able to complete the square.

then complete the square and multiply 2 inside the brackets.

subtraction as you already get the vertex form and know how to complete the square.

Vertex Form: y=2(x+2)^2-17
