34 = 28 - 2/5X

Move +28 to the other side. Sign changes from +28 to -28

34-28=28-28-2/5x

34-28=-2/5x

6=-2/5x

Multiply both sides by -5/2

6(-5/2)=-2/5(-5/2)x

Cross out 6 and 2, divide by 2 and becomes :

3*-5=-15=X

Answer: X=-15

Answer:

(3w - 7)(3w + 7)

Step-by-step explanation:

The expression is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Thus

9w² - 49

= (3w)² - 7²

= (3w - 7)(3w + 7)

Find the equation of the line show

nexus9112 [7]

Answer:

Equation : y = 2x + 3

Step-by-step explanation:

By considering any two coordinates from the line.

For example: I choose (0, 3) and (2, 7)

slope :

$slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{7-3}{2-0} = \frac{4}{2} = 2$

Equation :

$(y - y_1) = m (x - x_1)\\\\(y - 7) = 2 (x - 2)\\\\y - 7 = 2x - 4\\\\y = 2x - 4 + 7 \\\\y = 2x + 3$
