Answer:

x = 3, -5

Step-by-step explanation:

<u>Step 1:  Set the equation to 0</u>

<u />x^2+2x-15=0

<u>Step 2:  Factor</u>

<u />x^2+2x-15=0

x^2-5x+3x-15=0

(x-3)(x+5)=0

<u>Step 3:  Solve for x</u>

<u />x - 3 +3=0 +3

x = 3

x+5-5=0-5

x = -5

Answer:  x = 3, -5

Answer:

f = 2 + -15x-1 + x

Step-by-step explanation:

Simplifying

f(x) = x2 + 2x + -15

Multiply f (x)

fx = x2 + 2x + -15

Reorder the terms:

fx = -15 + 2x + x2

Solving

fx = -15 + 2x + x2

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Divide each side by 'x'.

f = -15x-1 + 2 + x

Simplifying

f = -15x-1 + 2 + x

Reorder the terms:

f = 2 + -15x-1 + x

I'm not quite sure but the first one I'm pretty sure....

+3,+5,+7,+9 so then +11,+13,+15,+17,+19

24+11=35 => 6th term

35+13=48 => 7th term

48+15=63 => 8th term

63+17=80 => 9th term

80+19=99 => 10th term

14,34,54,74,94

Each increases by 20...

94+20= 114

114+20= 134

134+20= 154

154+20= 174

174+20= 194

37,46,55,64,73

Each increasing by 9,

73+9= 82

82+9= 91

91+9= 100

100+9= 109

109+9= 118

What point on the parabola is closest to the point
Thepotemich [5.8K]

Answer:

Suppose the closest point is at p=(x0,y0), and set q=(−2,−3). Then the tangent to the parabola at p is perpendicular to ℓ, the line through p,q. and we end up numerically computing the roots from here.
