6 0

To multiply a negative number by any number, take the opposite, which would be positive, of the negative number and multiply it by the other number!! Then take the opposite of that Negative by Positive Number !
Examples:
-4*-4= 16
-4*4= -16
4*-4= -16

Hope that helps! :)

Yo sup??

this is of the form called slope and point... hence

y-11=-4(x+2)

therefore the correct answer is option A

The graph of a linear function has a slope of 1/4 and passes through the point (1,3). What is the y-intercept of the function?

Vikki [24]

Answer:

Step-by-step explanation:

In slope intercept form, y = mx + b, the m is the slope, the b is the y intercept, and x and y can be subbed in from the point you are given of (1, 3). We are told the slope, so everything we have fills in like this:

$3=\frac{1}{4}(1)+b$

Now we just need to solve for b:

$3-\frac{1}{4}=b$ and

$\frac{12}{4}-\frac{1}{4}=b$ so

$b=\frac{11}{4}$

Factor the expression completely. 625x4 - 256y4

scoundrel [369]

Answer:

(625 • (x4)) - 28y4

54x4 - 28y4 3.1 Factoring: 625x4-256y4

Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)

Proof : (A+B) • (A-B) =

A2 - AB + BA - B2 =

A2 - AB + AB - B2 =

A2 - B2Note : AB = BA is the commutative property of multiplication.

Note : - AB + AB equals zero and is therefore eliminated from the expression.

Check : 625 is the square of 25

Check : 256 is the square of 16

Check : x4 is the square of x2

Check : y4 is the square of y2

Factorization is : (25x2 + 16y2) • (25x2 - 16y2) 3.2 Factoring: 25x2 - 16y2

Check : 25 is the square of 5

Check : 16 is the square of 4

Check : x2 is the square of x1

Check : y2 is the square of y1

Factorization is : (5x + 4y) • (5x - 4y)this is the answer: (25x2 + 16y2) •(5x + 4y) • (5x - 4y)

A dinner plate has a circumference of 106.76 cm. What is the area of the dinner plate? Use = 3.14.

Sphinxa [80]

C=2pr, r=c/(2p)

a=pr^2, using r found above we get:

a=p(c^2/(4p^2))

a=(c^2)/(4p), since c=106.76 and we approximate pi as 3.14

a=(106.76^2)/(4*3.14)

a=11612.2176/12.56 cm^2

a≈924.54 cm^2 (to nearest one-hundredth of a square cm)
