Step-by-step explanation:
Answer:
√85 units
Step-by-step explanation:
If we move from (-1, 4) to (6,-2), we see x (the run) increasing by 7 and y (the rise) decreasing by 6.
The distance between these two points is found using the Pythagorean Theorem:
d = √ [7² + 6²] = √85 units (we cannot leave off the " √ " operator). Compare this to the 3rd answer choice.
Answer:
Step-by-step explanation:
Lets age of father be x and age of son be y
x+5=3(y+5)
x=3y+15-5
x=3y+10
x-5=7(y-5)
3y+10-5=7(y-5)
3y+5=7y -35
35+5= 7y-3y
40=4y
y=10 years son`s age
