Someone help me with these math problems please !! (It is not obligatory to put the explanation so I save time and you will answer me more quickly please!

the first option

Step-by-step explanation:

it is directly there in the problem description.

f(x) = 1.8x - 10

g(x) = -4

so, for f(x)=g(x) that automatically means

1.8x - 10 = -4

1.8x = 6

x = 6/1.8 = (6/1) / (18/10) = 10×6 / 18×1 = 60/18 = 10/3

one set of data has more variation than the other. hope this !

- (2, -7)

- lines r and s and lines t and u must be parallel
