Answer:
C
Step-by-step explanation:
You have to divide both sides by the coefficient of x
X - a leg (x > 6);
x - 6 - a leg;
x + 1 - a <span>hypotenuse;</span>
Use the Pythagorean theorem

Use:



The perimeter:
Answer:
total population in the year 2000=4400
total population in the year 2010=5060
no of people increased=5060-4400
=660
increase percent=660/4400*100%
=3/20*100%
=15%
Step-by-step explanation:
15/100*5060
0.15*5060
759
in 2020 population will be
5060+759
5819
therefore the population will be 5819 in 2020
-7x-5y=5
-(-9x-5y)=15 It's minus because negative times negative = positive
2x=-10
x= -5
-7(-5) - 5y = 5
35-5y =5
-5y = -30
y=6
Answer:
x=4,y=−2
Step-by-step explanation:
1 Solve for x in -2y+x=8
x=8+2y
2 Substitute x=8+2y into 3y+2x=2
7y+16=2
3 Solve for y in 7y+16=2
y=-2
4 Substitute y=-2 into x=8+2y
x=4
5 Therefore,
x=4
y=−2
