Answer:
C i believe
Step-by-step explanation:
the y intercept is at -4 and the line crossing through x is at 2 so the slope would be rise 4 run 2 also 4/2 and that can be simplified to 2.
Triangle PQR is isosceles. It's a unique side-angle-side triangle (both PQ and QR are congruent), so the other two angles in it are congruent and have the same measure. The interior angles of any triangle sum to 180° in measure, so
64° + <em>m</em>∠QPR + <em>m</em>∠PRQ = 180°
2 <em>m</em>∠QPR = 116°
<em>m</em>∠QPR = 58°
Angles PRQ and TRS form a vertical pair, so they are also congruent and <em>m</em>∠TRS = 58°.
This in turn means triangle RST is isosceles (again due to the side-angle-side postulate) so that angles RST and RTS have the same measure. Then
58° + <em>m</em>∠RST + <em>m</em>∠RTS = 180°
2 <em>m</em>∠RST = 122°
<em>m</em>∠RST = 61°
making the answer B.
Answer:
0
Step-by-step explanation:
Using the algebraic expansion
x³ + y³ = (x + y)³ - 3xy(x + y)
Given
x³ + y³ - 12xy + 64
= (x + y)³ - 3xy(x + y) - 12xy + 64
Substitute x + y = - 4 into the expression
= (- 4)³ - 3xy(- 4) - 12xy + 64
= - 64 + 12xy - 12xy + 64
= 0
