Find the value of d so that the line that passes through (a, b) and (c, d) has a slope of 12

fiasKO [112]

Answer:

I'm guessing that in the book or the homework sheet, they gave you

the values of 'a', 'b', and 'c', and you're supposed to find the value of 'd'.

If you have two points on the line, then the slope of the line is

(the change in 'y') divided by (the change in 'x') .

If the two points are (a, b) and (c, d), then the slope of the line is

(d - b) divided by (c - a) ,

and you have to find the value of 'd' that makes that whole expression

equal to 1/2.

(d - b) / (c - a) = 1/2

Multiply each side by (c - a): (d - b) = 1/2(c - a)

Add 'b' to each side: d = 1/2(c - a) + b

If you know the values of 'a', 'b', and 'c', you can find the value of 'd'.

What number must you add to complete the square?<br> x2 + 8x = 11

notsponge [240]

Answer:

Step-by-step explanation:

The number to add on both sides to complete the square is the square of the numerical coefficient that accompanies the term in "x", divided by 2.

That is in our case: $(\frac{8}{2}) ^2 = 4^2=16$

Therefore:

$x^2+8x+16=11+16\\x^2+8x+16 = 27$

That way the left hand side of the equation becomes the perfect square of the binomial: (x+4).

You can also prove that such is correct by developing the square of the binomial:

$(x+4)^{2} = (x+4)(x+4)= x^2+4x+4x+16= x^2+8x+16$
