Help me with this question I will mark brainlist no web link Solve :-9n²-64=0

1 answer:

6 0

Factorize

(3n + 8) (3n - 8) = 0
3n + 8 = 0 and 3n - 8 = 0

Solve both for n

3n + 8 = 0
3n = -8
n = -8/3

3n - 8 = 0
3n = 8
n = 8/3

Therefore n = -8/3 and n = 8/3

Tell whether the angles are adjacent or vertical. Then find the value of x.

maxonik [38]

Answer:

x = 63°

Step-by-step explanation:

~ They are adjacent angles because they have a common (one) vertex.

~ To find the value of x we must make an equation.

Angles on a straight line add up to 180°.

117 + x = 180

x = 180 - 117

x = <u>63°</u>

Find the coordinates if the midpoint of a line segment with endpoints (-3,4) and (7,9).

svetoff [14.1K]

Using the midpoint formula
$\frac{ x_{1}+ x_{2} }{2}, 
 \frac{ y_{1}+ y_{2} }{2}$
$\frac{-3+7}{2},
 \frac{4+9}{2}$
$\frac{4}{2},
 \frac{13}{2}$
$(2,6.5)$
So, your answer would be (2,6.5).
