It’s the letter “B” I think
Answer:
a) 20 units
b) 2 √10 units
c) 2 √17 units
Step-by-step explanation:
The distance formula is;
D = √(y2-y1)^2 + (x2-x1)^2
a) D = √(-7-9)^2 + (-7-5)^2
D = √256 + 144
D = √400
D = 20
b) D = √(10-8)^2 + (9-2)^2
D = √(2)^2 + 6^2
D = √4 + 36)
D = √40
D = 2 √10 units
c) D = √(1 + 7)^2 + (-8+10)^2
D = √(64 + 4)
D = √68
D = 2 √17 units
I think the answer is 1.97 hope it helps you
You add them and then divide by how many numbers there are.
a. (3+43)/2 = 23
b. 0
c. -1
Answer:
substituting x=5y into 2x-3y=7, Answer: y = 1 x = 5
Step-by-step explanation:
2(5y)-3y=7
10y-3y=7
7y=7
y=1
substitute y=1 into x=5y
x=5(1)
x=5
