Does anyone know how to do this?

71%

Step-by-step explanation:

She has 65% for 1st paper which have 120marks, we can calcule how marks she done:

120*0,65=78

On the 2nd pper she done:

80*0,80=64

The total marks was 120+80=200

She done 78+64=142

200—>100%

142—->x%

X=14200/200=71

Total procent score is 71%

(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.
