Answer:

(5,27)

Step-by-step explanation:

parabolas are symmetrical around the vertex. therefore x axis crossing points are equidistant from the vertex.

f(x) cross x axis when x=2 and x=8

the mid point of 2 and 8 is 5.

f(5)=-3(5-2)(5-8)

f(5)=27

vertex=(5,27)

Which of the binominals below is a factor of this trinomial? x2-10x-39
Reika [66]

Answer:

b

Step-by-step explanation:

given x² - 10x - 39

since the coefficient of the x² term is 1

consider the factors of - 39 ( constant term ) which sum to give - 10 ( the coefficient of the x term )

The factors are - 13 and + 3, hence

x² - 10x - 39 = (x - 13)(x + 3) ← in factored form

Hence (x - 13) is a factor → b

The total amount of money earned by all three plumbers on Monday was $1,400. On Tuesday they earned a total of $1,660, and on We
Alekssandra [29.7K]
Set of equations that can be used to calculate rate for each plumber:
2A+8B+8C = 1,400 --- (1)
4A+7B+10C = 1,660 --- (2)
3A+9B+9C = 1,660 --- (3)
------------------------------------
2*(1) - (2)
------------------------------------
4A+16B+16C = 2,800
4A+7B+10C = 1,660 -
------------------------------------
       9B+6C = 1,140 --- (4)
------------------------------------
3(2) -4(3)
-----------------------------------
12A+21B+30C = 4,980
12A+36B+36C = 6,600 -
-----------------------------------
         -15B-6C = -1,620 --- (5)
------------------------------------
(4) + (5)
------------------------------------
9B+6C = 1140
-15B-6C = -1620 +
-------------------------------------
-6B = -480 => 6B = 480 => B = 480/6 = 80
-------------------------------------------------------
Using (4), 9(80)+6C = 1140
720+6C = 1140 => 6C = 1140-720 = 420 => C = 420/6 = 70
------------------------------------------------------------------------------
Using (1), 2A+8(80)+8(70) = 1400
2A+640+560 =1400 => 2A = 1400-640-560 = 200 => A = 200/2 = 100
----------------------------------------------------------------------------------------------
The rates are:
A = $100
B = $80
C = $70
--------------------------------
On Thursday, number of calls: A = 4 hrs, B = 6 hrs, C = 3 hrs
Money earned = 4*100+6*80+3*70 = $1,090
