Aug 26, 2016 · Parallel lines have equal slope. The slope of line 6x −7y = 10 or 7y = 6x − 10 or y = 6 7 x − 10 7 ∴ slope = 6 7. Hence the slope of the line is also 6 7 [Ans]

Jan 29, 2017 · 6x^2+x-1 = (2x+1) (3x-1) Here are a couple of methods (in no particular order): Method 1 Note that: (ax+1) (bx-1) = abx^2+ (b-a)x-1 Comparing with: 6x^2+x-1 we want to find a, b such that …

Jun 4, 2018 · First of all, get rid of the parenthesis, multpilying each term inside it by 7: 7(4 −3x) = 7 ⋅ 4 − 7 ⋅ 3x = 28 − 21x The expression is now −6x + 28 −21x Now sum the similar terms, i.e. those …

f (x) has zeros +-sqrt (5) and -2 Given: f (x) = 3x^3+6x^2-15x-30 Note that all of the terms are divisible by 3. In addition, the ratio of the first and second terms is the same as that of the third and fourth terms.

Aug 1, 2015 · Explanation: In order to solve this quadratic equation by completing the square, you need to write the left side of the equation as the square of a binomial.

Sep 9, 2017 · First, divide each side of the equation by 3 to eliminate the need for parenthesis while keeping the equation balanced: 3(9 −6x) 3 = − 153 3 3(9 − 6x) 3 = −51 9 − 6x = −51 Next, subtract 9 …

Explanation: As you are using # f (x) # I am assuming you are at a higher level of Mathematics.

Nov 11, 2015 · f (1) + f (2) = 12. To get to this answer we have to substitute x in f (x)by 1 and then by 2. How? Let's see: f (x) = 6x - 3. So, f (1) = 6 (1) - 3 = 6 - 3 = 3, f (1 ...

We're dividing a single term, #6x^3#, into a polynomial, so we can take advantage of the following fact which allows us to effectively divide one term into other terms:
