Answer:

Step-by-step explanation:

-3x +4y = 20 Multiply this equation by 2.

======================

6x + 3y = 15

-6x + 8y = 40 Notice that -3 becomes -6, 4 becomes 8 and 20 becomes 40

===================== Add

11y = 55 The xs have disappeared. Divide by 11

y = 55/11

y = 5

=====================

6x + 3y = 15

6x + 3*5 = 15

6x + 15 = 15

6x = 15 - 15

6x = 0

6x/6 = 0/6

x =0

Step-by-step explanation:

Step 1: Define

10 - 4x ≤ 50

Step 2: Solve for x

Subtract 10 on both sides: -4x ≤ 40
Divide -4 on both sides: x ≥ -10

Here we see that any value x greater than or equal to -10 would be a solution to the inequality.

Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours

s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the COSINE operator to solve for the length of the course of ship B.

$cos(x) = \frac{adjacent}{hypotenuse}$
