Answer:

x = -4.59, -7.41.

Step-by-step explanation:

x^2 + 12x + 34 = 0

(x + 6)^2 - 36 +34 = 0

(x + 6)^2 = 36 - 34 = 2

x + 6 = +/-√2

x =   +/-√2 - 6

x = -4.59, -7.41

Given: g(x) = 3x² + 2 and h(x) = 2x + 2<br> Find: g(h(x))
kompoz [17]

Step-by-step explanation:

g(x) = 3x² + 2

h(x) = 2x + 2

g(h(x)) = g([2x + 2]) = 3[2x+2]² + 2

= 3[4x² + 8x + 4] + 2

= 12x² + 24x + 12 + 2

= 12x²+ 24x + 14

`bar(JK)` is dilated by a scale factor of n with the origin as the center of dilation, resulting in the image `bar(J'K')`. The s
dalvyx [7]

Answer:

Length of Bar JK=l

Bar (JK) is dilated by a scale factor of n, having origin as the center of dilation.

New line segment formed named  bar (J'K').

As given slope of bar(JK) =m

When we dilate a line segment with respect to origin , having origin as the center of dilation, there is no effect of slope on Dilation.

Length of bar (J'K')= (Length of bar JK)×(Scale factor)

                             = l×n Or n×l

Option (D) is correct.

Answer:

The slope is 3/8!

Explanation:

You put your equation in slope-intercept form, that is how you find the slope.

3x-8y=-20

-8y=-3x-20

y=3/8x-20

the fraction is now positive because the numerator and the denominator are both negative so they are changed into positive.

Hope This Helps!
