Answer:
c. Positive, as time goes on, more women are in army
Step-by-step explanation:
The graph shows the rise of the percentage of women in army in the course of time. In 1981 it was 9%. In 1991, it increased by 2% .In 2001, it rose sharply to 15%. But in 2011, it faced slight decrease in the percentage. But overall, the graph highlights the gradual increase of the percentage , which is positive.
Answer: The number is 1.
Step-by-step explanation:
create the formula from the problem
4x -7 = 1
move the seven to the other side by adding seven to both sides
4x (+7) -7 = 1 (+7)
4x = 8
then to get the x by itself, divide both sides by 4
4x/4 = 8/4
x = 2
You can check your work by plugging the x back into the original problem
4 (2) -7 = 1
8 -7 = 1
1 = 1 (this means it is correct)
Answer:
6 and 10
Step-by-step explanation:
xy=60
2(x+y)=32
x+y=16
y=16-x
Substitute y into area equation
x(16-x)=60
16x-x^2=60
x^2-16x+60=0
(x-10)(x-6)=0
x=10, 6
y=6, 10
Answer:5
Step-by-step explanation: F(-3)=(-3)^2 -4
(-3)^2=9
F(-3)=9-4
F(-3)=5
Their corresponding sides are proportional and their corresponding angles are equal.
