2x²+8x=x²-16

2x²-x²+8x+16=0

x²+8x+16=0

D=b²-4ac

=8²-4×1×16

=64-64

=0

x= -b+VD / 2a

=-8+V0 /2

= -8/2

=-4

Can someone help me with the questions in the picture?
OverLord2011 [107]

Answer:

y = 8

Step-by-step explanation:

Equation of the line that passes through (-2, 8) with a slope of 0, can be written in point-slope form, y - y_1 = m(x - x_1) and also in slope-intercept form, y = mx + b.

Using a point, (-2, 8) and the slope (m), 0, substitute x1 = -2, y1 = 8 and m = 0 in y - y_1 = m(x - x_1).

Thus:

y - 8 = 0(x - (-2))

y - 8 = 0

Rewrite in slope-intercept form

y - 8 + 8 = 0 + 8 (addition property of equality)

y = 8

What is the reciprocal of 5/9
Nat2105 [25]

Answer:

 \frac{9}{5}

Step-by-step explanation:

To find the reciprocal, divide 1 by the number given'

 

                                                   \frac{1}{\frac{5}{9} }

<em>                            (if you can't see it, it is 1 over 5/9)</em>

<em />

Simplify;

Multiply the numerator by the reciprocal of the denominator.

                                                    1(\frac{5}{9} )

<em>                         (if you can't see it, it is 1 × 5/9)</em>

<em />

Multiply \frac{9}{5} by 1.

                                                   \frac{9}{5}

<em />

So our answer is   \frac{9}{5}  !

We did it!
