Line passing through $(0,2),(1,-21)$ .

Step-by-step explanation:

$y=-23x+2\\at\ y\ axis\ x=0\\y=-23\times0+2\\y=2$

hence this line passes through $(0,2)$ .

When $x=1$

$y=-23\times1+2\\y=-21$

Hence this line passes through $(1,-21)$ .

What are the solutions of 4x2 - 8x +5 = 0 ?

MrRissso [65]

Answer:

x= {2+ i}/2 , {2- i}/2 = C

Step-by-step explanation:

4x² - 8x +5 = 0

using quadratic formula

x= {-b±√b²-4ac}/2a

x= [-(-8)±√(-8)²-4(4)(5)] /2x4 = [8±√64-80]/8= [8±√-16]/8 = {8±4 i}/8

x= {8+4 i}/8 , {8-4 i}/8

x=4 {2+ i}/8 , {2- i}/8

4 divides 8

x= {2+ i}/2 , {2- i}/2 = c
