Mathematics

arlik [135]3 years ago

Answer:

B

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c (m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (6, 0)

m = \frac{0-6}{6-0} = \frac{-6}{6} = - 1

Note the line crosses the y- axis at (0, 6 ) ⇒ c = 6

y = - x + 6 or y = 6 - x ⇒ B

at a building site there are 16 pallets with sacks of cement. The total weight of all the pallets and cement is 4,856 pounds. Ea
Neporo4naja [7]

Answer:

303.5 pounds

Step-by-step explanation:

If all the pallets weigh 4,856 together and each pallet weighs the same since they have equal cement and cement weight is equal, then 16 pallets will weigh 303.5 pounds each.

This is true because 4,856 / 16 = 303.5.

If two zeroes of a polynomial x3+5x2+7x+3 are -1 and-3 then find the third Zero
belka [17]

Answer:

Third zero is -1.

Step-by-step explanation:

consider the given polynomial is  

P(x)=x^3+5x^2+7x+3

It is given that -1 and -3 are two zeroes, therefore (x+1) and (x+3) are two factors of given polynomial.

The given polynomial can be rewritten as

P(x)=x^3+x^2+4x^2+4x+3x+3

P(x)=x^2(x+1)+4x(x+1)+3(x+1)

P(x)=(x+1)(x^2+4x+3)

Now, splitting the middle term, we get

P(x)=(x+1)(x^2+3x+x+3)

P(x)=(x+1)(x(x+3)+1(x+3))

P(x)=(x+1)(x+1)(x+3)

P(x)=(x+1)^2(x+3)

Here, power of (x+1) is 2. It means the multiplicity of zero -1 is 2.

So, three zeroes are -1, -1 and -3.

Therefore the third zero is -1.
