Darcy has a bladed spinner. A spinner has sections labelled 1,2,3 and 4. The table below shows information about some of the probabilities work out the value of x ( each section of the table , 1=x 2=0.15 3=0.05 4=0.2 5= 0.35

What is the length of the segment, endpoints of which are intersections of parabolas y=x^2− 11/4 x− 7/4 and y=− 7 /8 x^2+x+ 31/8 ?

The height of a birch tree, f(x), in inches, after x months is shown in the graph below. how much does the birch tree grow per month, and what will be the height of the birch tree after 10 months? a. the birch tree grows 1 inch per month. the height of the birch tree will be 16 inches after 10 months. b. the birch tree grows 2 inches per month. the height of the birch tree will be 26 inches after 10 months. c. the birch tree grows 3 inches per month. the height of the birch tree will be 36 inches after 10 months. d. the birch tree grows 2 inches per month. the height of the birch tree will be 24 inches after 10 months.

1. solve the system of equations by graphing: y = -3x - 3 m = b = y = 2x + 2 m = b = plz solve now
