B) draw the graph of y=-x^2+2x+1 on the grid below -3<x<5
-14<y<4

c) use your graph to find the solutions to the equations
-x^2+2x+1=0

d)i) on the grid, draw the line of symmetry of the graph
ii) write down the equation of this line of symmetry

e)i) draw the line y=-2 on the grid
ii) write down the coordinates of the interception of the two graphs.

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

$54.99

step-by-step explanation:

$54.99 includes 500 min. if she does not exceed 500 min then her bill is $54.99
