If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>
Answer:
Supplementary angles
Step-by-step explanation:
Supplementary angles are two angles whose sum is 180 degrees while complementary angles are two angles whose sum is 90 degrees.
Answer:
The answer to your question is the letter D. (x - 11)² + (y - 6)² = 72
Step-by-step explanation:
Data
Equation = ?
Center = (11, 6)
Point = (17, 12)
Process
1.- Calculate the length of the radius using the distance between two points formula.
d = 
x1 = 11 y1 = 6
x2 = 17 y2 = 12
-Substitution
d = 
d = 
d = 
d = 
radius = 
2.- Write the equation of the formula
(x - 11)² + (y - 6)² = (
)²
Result
(x - 11)² + (y - 6)² = 72
Step-by-step explanation:
2x + 3 = x-4
2x-x. = -4-3
x= -7
