Answer:
n = -4/5
Step-by-step explanation:
-3/4 n + 1/8 n= 1/2
use the rules of signs for multiplication
-3/4 n + 1/8 n= 1/2
multiply both sides 8
-6n + n = 4
collect like terms
-5n = 4
divide both sides by -5
n=-4/5
or alternative form
n=-0.8
The factoring method which can be considered for such a cubic tetranomial expression is; factor by grouping sum of cubes.
<h3>What factoring method can be considered for the polynomial?</h3>
It follows from the task content that the order of the Polynomial is 3 and the polynomial is a tetranomial as it contains 4 terms.
On this note, since 3x³ is not a perfect cube, it follows that the best factorisation method for such a polynomial is; factor by grouping sum of cubes.

Answer:
C proportional
Step-by-step explanation:
The answer is c because
proportional means equal
and as u can see in the photo you have represented a proportional relationship because ther line is going in and equal line across the axis and it is increasing at a proportional rate!
and there you go!
Because angleCBD＋angleBDC＋angleC＝180
so angleCBD＋angleBDC＝180－angleC＝180－82＝98
because BC＝DC
so angleCBD＝angleBDC
so 2 angleCDB＝98
so angleCDB＝49
so y＝29
