Answer:
y= -5x+15
Step-by-step explanation:
the point-slope formula is
where m= slope
plug the given point (4,-5) and slope m=-5 into the formula
simplify and distribute
subtract 5 from both sides
Answer:
The final estimate of √388 is 20.
Step-by-step explanation:
The number provided is:
<em>x</em> = 1388
Estimate the square root of 1388 as follows:
15² = 225
16² = 256
17² = 289
18² = 324
19² = 361
20² = 400
So, we now know that the square root of 388 lies between 19 and 20.
Check for 19.5²:
19.5² = 380.25
Check for 19.6²:
19.6² = 384.16
Check for 19.7²:
19.7² = 388.09 ≈ 388
The square root of 388 is closer to 19.7 or is approximately 20.
Thus, the final estimate of √388 is 20.
1 & 5/8 because 7/8 is closer to 1 whole than 5/8
The least common factor is 4
Answer:
