Answer:

(0,3)

Step-by-step explanation:

Solving Simultaneously, 4(5x + 3y = 9)

-5(4x - 2y = -6)

then, 20x + 12y = 36

-20x + 10y = 30

adding the two equations we get,

22y=66, hence y= 3

then substituting y in one of the equations

5x + 3(3) = 9 hence x = 0

Choose a situation that could be described by the following ratios, and write a sentence to describe the ratio in the context of

a_sh-v [17]

Part A:

Given the ratio 1 : 2, we can describe this ratio with the following situation.

The number of green balls to orange balls in the bag is in the ratio of 1 : 2. For every green ball in the bag, there are 2 corresponding orange ball.

Part B:

Given the ratio 29 : 30, we can describe this ratio with the following situation.

The ratio of the amount of sugar used to the amount of salt used to prepare the sugar-salt solution is 29 : 30. For every teaspoons of sugar used in the solution, 30 teaspoons of salt needs to be used.

Part C:

Given the ratio 52 : 12, we can describe this ratio with the following situation.

The number of kilometers travelled by the car and the bicycle is in the ratio of 52 : 12. For every 52 kilometers travelled by the car, the bicycle travelled 12 kilometers.

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 :)
