Answer:
y =1/2x+6
y = -2x+2
Step-by-step explanation:
Perpendicular line have slopes that multiply to -1
The slopes are negative reciprocals
-4*4 = 16 not perpendicular
1/2 * -2 = -1 perpendicular
1/5 *5 = 1 not perpendicular
2/3 * 2/3 = 4/9 not perpendicular
Add the whole numbers since they all have the square root of 6: 4+2-1=5. The answer is 5squre root of 6 or D :)
The error is 1.0 mile, too large.
Write the ratio
1.0 mile
--------------- = 0.069
14.5 miles
Mark's estimate is 6.9% greater than the actual distance.
Answer:
8.84 ×10⁻¹
Step-by-step explanation:
Move one decimal to the right to make one number go after the decimal. (ONLY one number from 0 - 9)
0.884 to 08.84
Now with how many times the decimal moves, it determines the power. Left equals positive and right is negative.
Standard form goes with × 10ˣ
the x next to 10 is the power.
The decimal moved 1 right so the power would be -1.
So,
8.84 × 10⁻¹
x3+3x2−4
________
9x4−12x2
Algebra isn't fun. Hope that helps though!
