Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.

Vlada [557]

Isolating s, the equation written in terms of s is:

$s = 12 - 0.5b$

-------------------------

The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

$b = 24 - 2s$

To solve for the lengths of the congruent sides, we isolate s, thus:

$b = 24 - 2s$

$2s = 24 - b$

Inverse of multiplication is division, thus:

$s = \frac{24 - b}{2}$

Separating into two fractions:

$s = \frac{24}{2} - \frac{b}{2}$

Solving each fraction:

$s = 12 - 0.5b$

Find the midpoint of the line segment joining the points P = (-7,1) and Q = (5,-7)

stealth61 [152]

Answer:

(-1, -3)

Step-by-step explanation:

The midpoint coordinates are the average of the respective end point coordinates:

M = (P +Q)/2

M = ((-7, 1) +(5, -7))/2 = (-7+5, 1-7)/2 = (-2, -6)/2

M = (-1, -3) . . . . the midpoint of PQ

12y^2+12y-3y^3 = 124-(y+5)

stepladder [879]

Answer:

${ \tt{12 {y}^{2} + 12y - 3 {y}^{3} = 124 - (y + 5)}} \\ 3 {y}^{3} - 12 {y}^{2} - 12y = - 124 + (y + 5) \\ {3y}^{3} - 12 {y}^{2} - 12y = - 124 + y + 5 \\ { \tt{3 {y}^{3} - {12y}^{2} - 11y + 119 = 0 }}$
