Write an equation of the line that passes through (2, -3) and is perpendicular to the line y=-2x-3

Natalija [7]

Answer:

$y=\frac{1}{2} (x-2)-3$ or $y=\frac{1}{2} x-4$

Step-by-step explanation:

The perpendicular slope is the opposite-reciprocal of the original slope:

Perpendicular slope of -2 is $\frac{1}{2}$

Write the equation in point-slope form ( $y=a(x-h)+k$ ):

$y=\frac{1}{2} (x-2)-3$

Convert to slope-intercept form if needed:

$y=\frac{1}{2} x-1-3$

$y=\frac{1}{2} x-4$

Find the value of x. 7 D 3 B В х С X =

bekas [8.4K]

Answer:

x = $\sqrt{30}$

Step-by-step explanation:

Using the Altitude- on- Hypotenuse theorem

(leg of Δ ABC )² = (part of hypotenuse below it ) × ( whole hypotenuse )

x² = 3 × (3 + 7) = 3 × 10 = 30 ( take the square root of both sides )

x = $\sqrt{30}$

Evaluate the expression 4(2x + 3) + 2(x + 1)-7

Svetlanka [38]

4 (2x + 3) + 2 (x + 1) - 7

8x + 12 + 2x + 2 - 7

10x + 7

10x = -7
10x/10 = -7/10

x = -7/10

hope this helps
