-3x + 6y + 5 = -7
<u> -5 -5</u>
-3x + 6y = -12
-3x + 3x + 6y = -12 + 3x
<u>6y</u> = <u>-12 + 3x</u>
6 6
y = -2 + 1/2x
-3x + 6(-2 + 1/2x) = -12
-3x - 12 + 3x = -12
-3 + 3x - 12 = -12
0x - 12 = -12

0 0
x = 0
-3(0) + 6y = -12
0 + 6y = -12

y = -2
(x, y) = (0, -2)
Answer:
A square pyramid has five faces: four triangle faces and one square face.
Step-by-step explanation:
Answer: 71 degrees.
Step-by-step explanation:
Due to the triangle being isosceles (Two sides are equal), we can assume that the angles will also be equal.
You can take 180 (The total of a triangle) and subtract by the known degree
180 - 38 = 142
Now we divide 142 by two, ONLY because this is case; both angles will be the same degree.
142 / 2 = 71
Therefore; x = 71
Answer:
79 degrees.
Step-by-step explanation:
M < 4 = m < 1 + m <3 (External Angle of a Triangle Theorem).
m < 4 = 26 + 53
= 79 degrees.
