Answer:

(5x+3)/((2x-3)(x+2)) = 3/(2x-3)+1/(x+2)

Step-by-step explanation:

Let

(5x+3)/((2x-3)(x+2)) = A/(2x-3)+B/(x+2)

5x+3=A(x+2)+B(2x-3)

5x+3=x(A+2B)+(2A-3B)

comparing x:

5=A+2B ... (1)

comparing constant:

3=2A-3B ... (2)

By solving:

A=3, B=1

(5x+3)/((2x-3)(x+2)) = 3/(2x-3)+1/(x+2)

What is the slope of the line through (–4, 3) and (5, 3)?

slamgirl [31]

Answer:

slope = 0

Step-by-step explanation:

Calculate the slope m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (- 4, 3) and (x₂, y₂ ) = (5, 3)

m = $\frac{3-3}{5+4}$ = $\frac{0}{9}$ = 0

How do you translate this:<br> 45% of two-fifteenths of the product of (x+1) and one-twelfth y

zvonat [6]

45% of two-fifteenths is equal to 0.45 * 2/15
the product of (x+1) and one-twelfth is equal to (x+1) * 1/12 or (1/12x + 1/12)
Multiply them together to get your answer.

Prove<br> cos(^2)x-sin(^2)x=1-2sin(^2)x

aleksley [76]

Answer:

Step-by-step explanation:

$cos^2x-sin^2x=1\\\\cos^2x+sin^2x=1\\\\so~cos^2x=1-sin^2x\\cos^2x-sin^2x=1-sin^2x-sin^2x=1-2sin^2x$
