Step-by-step explanation:
step 1. 17/21 - 2/10 = x (in order to subtract you need a common denominator)
step 2. (17/21)(10/10) - (2/10)(21/21) = x
step 3. 170/210 - 42/210 = x
step 4. 128/210 = 64/105 = x
step 5. x = 64/105.
Answer:
4i*sqrt(3)
Step-by-step explanation:
Break into prime factors.
48:2 * 2 * 2 * 2 * 3
sqrt(- 2 * 2 * 2 * 2 * 3) for every pair of factors take 1 out of the brackets and throw the other one away.
2 * 2 sqrt(-3) The square root of a minus is i
2 * 2 * i * sqrt(3)
4i * sqrt(3) Answer
To find the slope of the line, first find the slope of 3x + y = 5, and then its opposite reciprocal.
3x + y = 5
y = -3x + 5
the slope of 3x + y = 5 is -3.
the slope is -3, so the opposite reciprocal slope is 1/3.
the equation of any line is y = ax + b
to find this line, y = 3, x = -9, and the slope is 1/3.
3 = -9a + b
3 = -9 (1/3) + b
3 = -3 +b
b = 6
substitute a and b into the equation
y = ax + b
y = 1/3x + 6
the equation of the line is y = 1/3x + 6.
