Answer:

$y = \frac14 x - 4$

Step-by-step explanation:

The slope is 1/4 since y increases 1 when x increases by 4 (you divide deltaY by deltaX).

Then, to make it go through (0,-4) you subtract -4.

julia-pushkina [17]

Answer: 49

Step-by-step explanation:

This polygon has 5 sides, meaning its interior angles add to $180(5-2)=540^{\circ}$ .

$3x+30+x+2x+x+20+3x=540\\\\10x+50=540\\\\10x=490\\\\x=49$

How do I find x in this problem, x/5-2/3=3/2

d1i1m1o1n [39]

<h3 /><h3> $⇒\frac{x}{5} - \frac{2}{3} = \frac{3}{2} \\ \frac{x}{5} = \frac{3}{2} + \frac{2}{3} \\ \frac{x}{5} = \frac{3 \times 3}{2 \times 3} + \frac{2 \times 2}{3 \times 2} \\ \frac{x}{3} = \frac{9 + 4}{6} \\ \frac{x}{3} = \frac{13}{6} \\ = \frac{13}{6} \times 3 \\ = \frac{13}{2}$ </h3>
