A group of t tourists visits a museum. Thirty of the tourists go to see a planetarium show. The remaining tourists are divided evenly into 4 groups to tour the exhibits. How many tourists are in each group that tours the exhibits? (t – 30) tourists

(t/4-30) tourists

1/4(t-30) tourists

1/4(t+30) tourists

g(x) = x² + 2

step-by-step explanation:

it is given that the graphs are the same shape.

the only difference is that the red graph is 2 units higher than the blue graph.

that is to say that the red graph is simply the blue graph that has been moved vertically by 2 units in the positive y direction.

hence

g(x) = f(x) + 2

or

g(x) = x² + 2

6, 10

9, -13

12, -21

18, -23

step-by-step explanation:

you just add 6 to the x-coordinate and subtract 10 from the y-coordinate.
