The inequality that represents the domain of the function is $\frac 12x - 10 \ge 0$

<h3>How to determine the domain?</h3>

The function is given as:

$f(x) = \sqrt{\frac 12x - 10} + 3$

Set the radicand greater than or equal to 0

$\frac 12x - 10 \ge 0$

Multiply through by 2

x - 20 ≥ 0

Add 20 to both sides

x ≥ 20

Hence, the domain of the function is x ≥ 20

Answer:

3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°

Step-by-step explanation:

Triangle g

180° = 80° + 3y + 2y

100° = 5y

y = 20°

Triangle h

y = 180° - 130°

y = 50°

180° = 4x + x + 50°

130° = 5x

x = 130 / 5

x = 26°

A line through (-4,6) with slope-3/2 and graph

marin [14]

Answer:

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

Step-by-step explanation:

Given

Passes through: (-4,6)

Slope: -3/2

Required

The equation and graph

The equation is calculated as:

$y = m(x - x_1) + y_1$

Where

$m = -\frac{3}{2}$

$(x_1,y_1) = (-4,6)$

So, we have:

$y = -\frac{3}{2}(x --4) + 6$

$y = -\frac{3}{2}(x +4) + 6$

Open bracket

$y = -\frac{3}{2}x -6 + 6$

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