How can we get equation b from equation a ?

Choose 1 Multiply/divide both sides by the same non-zero constant. Multiply/divide both sides by the same variable expression.

Step-by-step explanation:

Multiply/divide both sides by the same non-zero constant

hope this helps

have a good day :)

Step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
