(2x^2-17x-38)/(2x+3)

Answers

Answer 1

Answer: (2x^2-17x-38)/(2x+3)
=-15x^2-38)/2x+3)
=-7.5x^2/2x+3
=-3.525x-38+3
=-3.525x-35

Answer 2

Answer: (2x^2-17x-38)=(2x+3)(x-10)+8
(2x^2-17x-38)/(2x+3)=x-10+8
(2x^2-17x-38)/(2x+3)=x-2

Just plug in the domain values in the equation to find y.

f(x)=-x+4

f(-3)=-(-3)+4=3+4=7
f(-2)=-(-2)+4=2+4=6
f(-1)=-(-1)+4=1+4=5
f(1)=-1+4=-1+4=3

So the range is Option B : {7, 6, 5, 3}

Convert the polynomial equation y=(x+2)(x-6)(x+7) from factored form to general form

Answers

y = (x+2)(x-6)(x+7)

(x+2)(x+7)
x^2 - 6x + 2x - 12
x^2 - 4x - 12

(x^2 - 4x - 12)(x + 7)
x^3 + 7x^2 - 4x^2 - 28x - 12x - 84
x^3 + 3x^2 - 40x - 84

y = x^3 + 3x^2 - 40x - 84

$y = (x + 2) (x -6) (x + 7) \n \n i.e, y = (x+2) (x^2 - x - 42) \n\n => y = x^3 + 3x^2 - 40x - 84$

Dirk Nowitzki of the Dallas mavericks scored 44 points in a recent basketball game. He scored no 3-point shots, but made a number of 2-point field goals and 1-point free throws. He scored 30 times. How many 2-point shots did he make? How many free throws did he make?

Answers

x - 2-point field goals
y - 1-points field goals

2x + y = 44
x + y = 30

2x = 44 - y
y = 30 - x

2x = 44 - y
y = 30 - (22 - 1/2y)

2x = 44 - y
y = 30 - 22 + 1/2y

2x = 44 - y
1/2y = 8

2x = 44 - y
y = 16

2x = 44 - 16
y = 16

2x = 28
y = 16

x = 14
y = 16

x + y = 30
14 + 16 = 30
L = R

2x + y = 44
28 + 16 = 44
44 = 44
L = R
