Answer:

b=-3/4 or b=-0.75

Step-by-step explanation:

$2(-2b+3)=9$

$2b+3=\cfrac{9}{2}$

$-2b=\cfrac{9}{3} -3$

$-2b=\cfrac{3}{2}$

$b=-\cfrac{\frac{3}{2} }{2}$

$b=-\cfrac{3}{2\times 2}$

$b=-\cfrac{3}{4}$

Hope it helps! :)

Answer:

B. $r_{x-axis}(x,y) \circ R_0,90\degree)$

Step-by-step explanation:

The vertices of triangle ABC have coordinates A(5,2) B(2,4) and C(2,1).

The mapping for reflection in the x-axis is

$(x,y)\to (x,-y)$

When we reflect triangle ABC in the x-axis, we obtain

A1(5,-2) B1(2,-4) and C1(2,-1).

The mapping for 90 degrees clockwise rotation about the origin is

$(x,y)\to (y,-x)$

When we rotate the resulting triangle through 90 degrees clockwise above the origin, we obtain;

A2(-2,-5) B2(-4,-2) and C2(-1,-2).

The vertices of triangle A''B''C'' also have coordinates A''(-2,-5) B''(-4,-2) and C''(-1,-2).

Hence the rule that describes the composition of transformation that maps ABC to A''B''C'' is

$R_0,90\degree \circ r_{x-axis}(x,y)$

The correct choice is B.

Evaluate: \frac{23}{56} + \frac{3}{8} - ( - \frac{4}{28} )

MrMuchimi

I think this is what you mean. I don't know why the Latex didn't work. Good for you that you can use it.

$\frac{23}{56} + \frac{3}{8} - \frac{-4}{28}$
$\frac{23}{56} + \frac{3}{8} - \frac{-4}{28}$ Reduce the 4/28 to 1/7
$\frac{23}{56} + \frac{3}{8} - \frac{-1}{7}$ Make the 2 minuses into a +
$\frac{23}{56} + \frac{3}{8} + \frac{1}{7}$ 56 is the common denominator.
$\frac{23}{56} + \frac{21}{56} + \frac{8}{56}$

Answer = [23 + 21 + 8] / 56 = 52 / 56 = 13 / 14 When both numerator and denominator are divided by 4

13 / 14 <<<< answer.
