Answer: 36

Step-by-step explanation:

$\overline{AB} \cong \overline{BC}$ (Triangle ABC is isosceles)

$m\angle CAB=m\angle CBA=30^{\circ}$ (base angles of an isosceles triangle are congruent)

$\angle MCB=90^{\circ}$ (In triangle CMB, angles in a triangle add to 180 degrees)

$\angle ACM=30^{\circ}$ (triangle sum theorem)

$MB=24$ (30-60-90 triangle CMB)

$AB=12$ (sides opposite congruent angles in a triangle are congruent)

$AB=36$ (segment addition postulate)

Which equation represents the graph?

klio [65]

The second option.

That is because
$y -3 = - \frac{1}{2}(x + 1) \\ (y -3)+3 = (- \frac{1}{2} x - \frac{1}{2}) + 3 \\ y = - \frac{1}{2}x + 2 \frac{1}{2}$

sineoko [7]

Answer:

11.5 hours

Step-by-step explanation:

25 pages every 75 minutes (1 1/4)

Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)

230 pages would mean 690 minutes (times the 3 by 230)

690/6 = 11.5

Y = x - 4 y = 4x + 2 x = y =

marshall27 [118]

Answer:

x=-2 y=-6

Step-by-step explanation:

x-4=4x+2

subtract x from both sides

-4=3x+2

subtract 2 from both sides

-6=3x

divide by 3 on both sides

x=-2

y=-2-4=-6

y=4(-2)+2=-8+2=-6
