Answer:
Estimate.
18,185 + 493 = 20,000 + 500 = 25,000
Step-by-step explanation:
18,185 + 493
18,185 rounded to the nearest ten thousand is 20,000
493 rounded to the nearest hundred is 500
Answer:
y = 3/2x + 2
Step-by-step explanation:
Step 1: Write original equation into slope-intercept form
3y = -2x + 3
y = -2/3x + 1
Step 2: Find slope of perpendicular line
Take the negative reciprocal of the other slope.
m = 3/2x
Step 3: Find <em>b</em>
y = 3/2x + b
-4 = 3/2(-4) + b
-4 = -6 + b
b = 2
Step 4: Rewrite perpendicular equation
y = 3/2x + 2
