In slope-intercept form find a line that passes through (-4, 6) and is perpendicular to 2x + 3y = 12
leonid [27]

Answer:

y = 3/2 * x + 12

Step-by-step explanati

2x + 3y = 12

y = -2/3x + 4

slope: -2/3

slope' of perpendicular line: 3/2

6 = 3/2 * (-4) + b

b = 12

equation: y = 3/2 * x + 12

The equation of line CD is (y-3) = -2 (x -4). What is the slope of a line perpendicular to line CD
larisa [96]

This linear equation is written in point-slope form, meaning that the constant outside of the (x - 4) is the slope: -2.

Perpendicular lines' slopes are oppositely negated, so -2 turns into positive 1/2.

So, the slope is 1/2.

Which equation could be solved using this application of the quadratic formula? A. -2x2 â’ 8 = 10x â’ 3 B. 3x2 â’ 8x â’ 10 = 4 C
hodyreva [135]

The given question can be solve using quadratic formula.

The correct option is (c) 3x^2 +8x -10=-8.

Given:

The given equation is,

x=\dfrac{-8\pm\sqrt{8^2-4(3)(-1)}} {2(3)}---------------------------(1)

Write the general quadratic equation.

ax^2 + bx +c=0

Write the quadratic formula.

x  =\dfrac {-b \pm  \sqrt{(b^2 - 4ac)} } {2a}------------------------------- (2)

Compare equation (1) and (2).

a=3\\b=8\\c=-2

Substitute the value of a, b and c in general quadratic.

3x^2 +8x -2=0

Subtract 8 from each side of above equation.

3x^2 +8x -2 -8=0-8\\3x^2 +8x -10=-8

Thus, the correct option is (c) 3x^2 +8x -10=-8.
