Y = 2/5x + 3. The slope here is 2/5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal. we " flip " the slope and change the sign. So the perpendicular line will need a slope of -5/2.
y = mx + b
slope(m) = -5/2
(4,-4)....x = 4 and y = -4
now we sub and find b, the y int
-4 = -5/2(4) + b
-4 = - 10 + b
-4 + 10 = b
6 = b
so ur perpendicular line is : y = -5/2x + 6
Answer:
Step-by-step explanation:
4/9-1/6=5/18
First, we need to calculate 80% of what they earned before:
50,000 * 0.80 = 40,000 per year
Social Security = 1200 a month x 12 months ( 1 year) = 14,400 per year
Additional income = 40,000 - 14,400 = $25,600 per year
Answer:
2 ^ 20
Step-by-step explanation:
The answer of first question is 'true'.
The answer of the second question is 4.
3 - 2x = -5
-2x = -5-3
-2x = -8
2x = 8
x = 8/2
x = 4
The answer of the third question is (2,5).
2 = 5 - 3
