Answer:(7/8 - 4/5)^2 = 9
1600
= 0.005625
Step-by-step explanation:
Subtract: 7
8
- 4
5
= 7 · 5
8 · 5
- 4 · 8
5 · 8
= 35
40
- 32
40
= 35 - 32
40
= 3
40
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(8, 5) = 40. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 8 × 5 = 40. In the next intermediate step the fraction result cannot be further simplified by cancelling.
In words - seven eighths minus four fifths = three fortieths.
Exponentiation: the result of step No. 1 ^ 2 = (3
40
) ^ 2 = 32
402
= 9
1600
In words - three fortieths squared = nine one-thousand six-hundredths.
Answer:
The answer to your question is: y = -2x + 10
Step-by-step explanation:
Data
Point = (1, 8)
Line y = x/2 + 3
perpendicular
slope = 1/2 but the lines are perpendicular, then slope = -2
Equation
( y - y1) = m ( x - x1)
(y - 8) = -2(x - 1)
y - 8 = -2 x + 2
y = -2x + 2 + 8
y = -2x + 10
