A.Wrong its 2^8 as 2x4=8
B.wrong its 3^-10 and not its reciprocal
C.correct
D.correct
E.correct
F.wrong as 3x2=6
The answer would be 240 because 12 times 8 equals 96 and 18 times 8 equals 144 but you have to add it so the answer is 240
Use the quadratic formula with a = 2, b = -5, and c = 1
x = -b ± sq rt b2 - 4ac
-------------------- <---------- Please note: sq rt is over entire expression of b^2 - 4ac
2a
x = - (-5) ± sq rt (-5)2 + 4(2)(1)
-------------------------------- <---------Please note: sq rt is over entire expression (-5)2 + 4(2)(1)

Answer:
12x + y = 16
Step-by-step explanation:
Standard Form: Ax + By = C
Step 1: Write point-slope form
y + 4 = -12(x - 1)
Step 2: Find slope-intercept form
y + 4 = -12x + 12
y = -12x + 16
Step 3: Find standard form
12x + y = 16
Answer:
A = 140°
B = 40°
C = 140°
Step-by-step explanation:
1. Since we know that opposite angles are equal, b = 40°
2. Since we also know that the angle of a line adds to 180°,
a = 180° - 40°
So, 140°
Then repeat step 1 to find C through A.
