Mathematics
1 answer:
alexandr402 [8]2 years ago
3 0

Step-by-step explanation:

\frac{y}{20 \sqrt{3} }  =  \sin(30)

y = 20 \sqrt{3}  \times   \frac{1}{2}

y = 10 \sqrt{3}

\frac{x}{20 \sqrt{3} }  =  \cos(30)

x = 20 \sqrt{3}  \times  \frac{ \sqrt{3} }{2}

x = 30

option D, x=30 and y = 10√3

Given the system of inequalities:
Margaret [11]
Answer:
First inequality: y > \frac{4}{5} x - \frac{1}{5}
Second inequality: y < 3 + x

Explanation:
The inequality in slope-intercept form has the following general formula:
y < mx + c or y > mx + c (according to the given sign)
where m is the slope and c is the y-intercept

This means that to get any inequality in slope-intercept form, we will have to isolate the y on one side of the inequality.

First given inequality:
4x - 5y < 1
4x - 5y + 5y < 1 + 5y
1 + 5y > 4x
1 + 5y - 1 > 4x - 1
5y > 4x - 1
y > \frac{4}{5} x -  \frac{1}{5}
comparing this to the general form, we would find that:
slope (m) = 4/5
y-intercept (c) = 1/5

Second given inequality:
y - x < 3
y - x + x < 3 + x
y < 3 + x
comparing this to the general form, we would find that:
slope (m) = 1
y-intercept (c) = 3

Hope this helps :)
