Answer:
I'm pretty sure its -4-12x but I could be wrong
Step-by-step explanation:
First I tried to solve for x but got -12x+4 so to get 4 on the other side of the equation I subtracted and got -4-12x I hope this helps :)
Step-by-step explanation:
Equation of straight line is y=mx+c
choose any two points on straight line
for me I choose:(-3,11) and (3,-1)
use these two points to find gradient,m.
m= (-1-11)/(3-(-3))
m= -2
now, y=-2x+c
choose any point on the straight line
I choose point (3,-1)
sub the point into the equation to find c
-1=-2(3)+c
c=5
equation: y=-2x+5
yes
3/7 multiplied by 6 (each no.) gives 18/42
Thus, 18/14=18/42
3/7=18/42
I combined the three steps together and the following are my thoughts:
We can set the fixed fee for renting as (f) and an dynamic fee related to days as (d) per day, then we have:
Then we could get f=16, d=4, so we could have the equation as follows:
y = 16 + 4x
Answer:
Measure of exterior angle of a regular polygon= 360°
No of sides: Sum of exterior angle
---------------------------------
Each interior angle
= 360°÷24
= 15
#
Hence, the regular polygon has 15 sides..
