X/5=2/3=5/y 2/3 4/9 1

1 answer:

5 0

$\frac{x}{5}= \frac{2}{3} = \frac{5}{y}$
Break the equation into parts;
$\frac{x}{5} = \frac{2}{3} ; \frac{2}{3}= \frac{5}{y}$
Solving for x;
$\frac{x}{5} = \frac{2}{3}$
x= $\frac{10}{3}$
Solving for y;
$\frac{2}{3} = \frac{5}{y} 
y= \frac{3*5}{2} 
y= \frac{15}{2}$
$\frac{x}{y} = \frac{10/3}{15/2}$
$\frac{x}{y} = \frac{4}{15}$

The graph for the system of inequalities without the shading of its solution set is shown on the coordinate grid.

BartSMP [9]

Answer:

C. Area 3

Step-by-step explanation:

<h3>The first line</h3>

Line x - y > 5 ⇒ y < x - 5

This line has positive slope and the y-intercept is -5, shaded area is below the line, covers the areas:

Area 3 and Area 4

<h3>The second line</h3>

Line x + 2y < -6 ⇒ 2y < - x - 6 ⇒ y < -1/2x - 3

This line has negative slope and the y-intercept is -3, shaded are is below the line, covers the areas:

Area 2 and Area 3

Solution of the system is the intersection of the areas:

Area 3

Determine if y = 2x + 1 is a function

horsena [70]

Yes! There is one output and one input, which is the definition of a function. You can also graph the function and test for the vertical line test. Graph a few points, connects the dots. Draw a vertical line through the graph and if the vertical line passes through the graph more than once, it is not a graph.

Can someone plz help me!??!

Vaselesa [24]

To solve for x, you simplify both sides of the equation and then isolate the variable.

10x + 12 = $72.00
x = 6

Six people attended the concert.
Check the answer:
(10 • 6) + 12 = 72.00
60 + 12 = 72.00

Solve the simultaneous linear equation 2x+5y=11, 7x+4y=2

Andrews [41]

Answer:

x = - $\frac{34}{27}$ and y = $\frac{73}{27}$

Step-by-step explanation:

2x + 5y = 11

7x + 4y = 2

Let's try elimination here since we have a system of equations:

-7(2x + 5y = 11) = -14x - 35y = -77

and

2(7x + 4y = 2) = 14x + 8y = 4

The x's cancel out now so let's combine the two equations:

-35 + 8 = -27

-77 + 4 = -73

-27y = -73

y = $\frac{73}{27}$

Now that we have y's value, let's plug that value in for y in the other equation. You may choose whichever equation you want to solve for x but it is recommended to use the easiest one. (Since this value is complicated, it won't really matter.)

2x + 5( $\frac{73}{27}$ ) = 11

2x + $\frac{365}{27}$ = 11

2x = - $\frac{68}{27}$

x = - $\frac{34}{27}$

To check and make sure you have the correct values, plug both values into the orginal equation and make sure the equation is true.
