The computation of the equation shows that the answers will be:

12. 340 units

13. 2(270) + (2 × x) = 690

14. x = 5

<h3>How to compute the equations?</h3>

12. The first equation that's given will be:

(13.50 × x) - (3.65 × x) = 3349

13.50x - 3.65x = 3349

9.85x = 3349

x = 3349/9.85

x = 340

The number to break even is 340 units

13. The equation that can be used to find the perimeter will be:

2(270) + (2 × x) = 690

540 + 2x = 690

2x = 690 - 540

2x = 150

x = 150/2 = 75

14. x + x + 2 + 8 = 20

2x + 10 = 20

2x = 20 - 10

2x = 10

x = 10/2

x = 5

The equation of a line is given by, 13x – y + 12 = 0. Find the slope and both the intercepts.

MArishka [77]

Answer:

The slope is 13.

The x intercept is $x=\frac{-12}{13}$ .

The y intercept is $y=12$ .

Step-by-step explanation:

1. Finding the slope.

This is a linear equation, because it's graph forms a line. In a linear equation, the slope is always the value that multiplies x. In this case, x is being multiplied by 13, therefore, the slope is 13.

2. Finding the x intercept.

The x intercept is found when the value of y is 0. Let's replace the value of y for 0 in the equation and solve the x:

$13x-y + 12 = 0\\\\13x-(0) + 12 = 0\\\\13x+12 = 0\\\\13x= -12\\\\x=\frac{-12}{13}$

The x intercept is $x=\frac{-12}{13}$ .

3. Finding the y intercept.

The y intercept is found when the value of x is 0. Let's replace the value of x for 0 in the equation and solve the y:

$13x-y + 12 = 0\\\\13(0)-y + 12 = 0\\\\-y + 12 = 0\\\\-y=-12\\\\y=12$

The y intercept is $y=12$ .

Prove this identity sin(2A)=2sinAcosA.

34kurt

The solution for proving the identity is as follows:

sin(2A) = sin(A + A)
As sin(a + b) = sinacosb + sinbcosa,
sin(A + A) = sinAcosA + sinAcosA

Therefore, sin(2A) = 2sinAcosA
