Answer: (y - 2) = - ¹/₄ (x - 10) </h2>
Step-by-step explanation:
When two lines are perpendicular, the product of their slope/gradient = -1. Another way of thinking of this is that they are negative-reciprocal of each other.
Let y = 4x + 6 be [a] & the perpendicular line [b]
since the slope of [a] = 4
then the slope (m) of [b] = - ¹/₄
Since we know the slope of [b], we can use the point-slope form (y - y₁) = m (x - x₁); where (x₁ , y₁) = (10 , 2) & m = - ¹/₄
∴ the equation of the perpendicular line : (y - 2) = - ¹/₄ (x - 10)
Answer:
A
Step-by-step explanation:
Answer:
17/18
Step-by-step explanation:
1/2 + 4/9
9/18 + 8/18 (need common denominators to add)
17/18
cannot simply because 17 is prime
Answer:
Step-by-step explanation:
5/14=x/28
Cross multiply to get
14x=140
Divide both sides by 14
x=10
Or
See that 28 is 14*2 and multiply 5*2 to get the same answer
