Solve the equation 3x2 + 19x + 9 = 0 to the nearest tenth.

×=-0.8

Step-by-step explanation:

3×2=6

6+9=15

19x+15=0

subtract 15 from both sides

19x=-15

divide both sides by 19

x=-0.789 which rounds up to -0.8

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
