28-3c-4=2c+12+c now group this on the same side. Remember when you move the number to the other side of = it changes the sign.
28-4-12=2c+c+3c
12=6c
12/6=c
2=c
To solve the question we need to calculate the equation of the straight line;
the equation is given by:
m=(y1-y)/(x2-x)
where;
m is the slope;
selecting 2 points from the graph say (0,2) and (2,0), the slope of the graoh will be:
m=(0-2)/(2-0)=-1
thus using point (-2,4) the equation will be given by:
-1=(y-4)/(x+2)
-1(x+2)=(y-4)
this can be written as:
-x-2=y-4
this can be written as:
y+2=-x+4
this can be written as:
y+2=-(x-2)
The answer is A.y+2=-(x-2)
Answer:
a. $1000
b. 100
c. 900
d. 1017
Step-by-step explanation:
a.
marked price = 800×1.25=1000
b.
discount amount
1000×0.9=900
1000-900=100
c.
1000×0.9=900
d.
900×1.13=1017
Answer:
8. tenths
9. 90,000
Step-by-step:
tenths: ones are 10 times as small and move the decimal point one more time, tenths (note the ths)
90,000 the 9 in 295 is 90. 90*1000=90,000
