If f(x) = 2x + 7 and g(x)= 3x² -1, what expression represents (f(g(x)) ? A 6x2 +5
B 6x2 +12
C 3x2 - 2x -8
D 3x2 + 2x + 6

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

your answer is -9

step-by-step explanation:

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
