Answer:
None of the above.
Step-by-step explanation:
The system of equations which should have the same solution as the system below;
x + 4y = 11
4x + 2y = 16
is
x + 4y = 11
-8x - 4y = - 32
This system of equations is missing from your choices.
The trick is that -2 is multiplied to the second equation of the first system.
i.e -2 (4x + 2y = 16) gives; -8x - 4y = -32
Answer: B
Step-by-step explanation:
Acute angle, right angle, obtuse angle, straight angle, supplementary angles, complementary angles, vertical angles, & adjacent angles! hope this was what you were looking for!
Step-by-step explanation:
f(x) = 4x²
g(x) = x + 1
= (fog)(x)
= f( g(x) g
= 4x²
= 4(x + 1)²
Option → C
Triangle ABC is isosceles (even tho' it doesn't look so).
m<BDE = m<BED because of that.
Thus, 66 degrees + 2 m<BDE = 180 degrees, and
2 m<BDE = 114 degrees. Thus, m<BDE = 57 degrees.
