Ms. Cook's class bought 2 bags of concrete and some bricks to build a border for their class garden. The bricks cost
$51. The total cost of the bricks and the concrete was $57.
Which equations can be used to find the cost, b, of 1 bag of
concrete?
o 2(51) + b = 57
o 2b + 51 = 57
O 2 + 51b = 57
ob + 51 = 57

shift 4 units up, and 1 unit left.

it will translate f(x) = 3^x to g(x) = 3^(x+1) + 4

50x5=$250

step-by-step explanation:

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
