Answer:
6,653 square miles
Step-by-step explanation:
Subtract South Dakota's area, 77,353 by North Dakota's area, 70,700, and you get 6,653
Answer:
20 units
Step-by-step explanation:
The 3 part of the ratio refers to 15 units
Divide 15 by 3 to find the value of one part of the ratio
15 ÷ 3 = 5 ← value of 1 part of the ratio, thus
4 parts = 4 × 5 = 20 units ← perimeter of larger figure

originally. Then you reduces the side lengths a so it will be

Just note that 40% is the same as 2/5.<span />
Answer:
9. No
10. Yes
Step-by-step explanation:
The first one is not, since you have (3, 3) and (3, 9). In a function, each x maps to a single y.
The second one is since every x appears only once.
Answer:
Any equation of the line that is different from y=x is the solution to the problem.
Step-by-step explanation:
step 1
Find the slope of the line that passes through the points (1, 1) and (5, 5)
m=(5-1)/(5-1)=1
step 2
Find the equation of the line into slope point form
y-y1=m(x-x1)
we have m=1
(x1,y1)=(1,1)
substitute
y-1=(1)(x-1)
y=x-1+1
y=x
therefore
Any equation of the line that is different from y=x is the solution to the problem.
