MATH PROBLEM! PLEASE HELP ME IT'S TTM!!!

Answer:

The system of equations i.e. y - x = 15 and 25 + 2x = y represents the correct graph as the point of intersection of this system is (x, y) = (-10, 5) which is also the point of intersection of the two lines shown in graph.

Step-by-step explanation:

The graph is showing the following system of equations:

y - x = 15 and 25 + 2x = y

The reason is very simple. As the point of intersection of two lines is (-10, 5). It means the two lines in the graph meet at the x-coordinate = -10 and y-coordinate = 5. So, (-10, 5) is the point of intersection of the two lines as shown graph.

If we solve the system of equations i.e. y - x = 15 and 25 + 2x = y to get the values of x and y to determine its intersection. So, we would get the value of x = -10, and y = 5. Hence, The graph is showing the system of the equation of y - x = 15 and 25 + 2x = y.

Verification: Lets solve system of equations i.e. y - x = 15 and 25 + 2x = y to get the values of x and y to determine its intersection.

y - x = 15

y = x + 15

Substitute x+15 for y in 2x+25 = y

2x + 25 = y

2x + 25 = x + 15

x = −10

Substitute x = −10 for x in y = x+15

y = x + 15

y = −10 + 15

y = 5

So, x = −10 and y = 5

Hence, The graph is showing the system of the equations of y - x = 15 and 25 + 2x = y.

The system of equation in first choice (y=15 and y =25), represent a pair of parallel lines which will never intersect at any point, and two other system of equations in the given options yield different point of intersections. Hence, they do not represent the corresponding graph.

Therefore, only the system of equations i.e. y - x = 15 and 25 + 2x = y represents the correct graph as the point of intersection of this system is (x, y) = (-10, 5) which is also the point of intersection of the two lines shown in graph.

Write an equation in slope intercept form of the line has a slope of 2/5 and a Y intercept of -7

inessss [21]

Step-by-step explanation:

Slope (m) = 2/ 5

Y-intercept (c) = - 7

writing in slope intercept form

y = mx + c

y = 2/5 x - 7

Hope it will help :)

I NEED HELP!!!! I am currently reviewing for my last test, and i am struggling with this problem. I KNOW WHAT THE ANSWER IS BUT

stira [4]

Answer:

$336\:\mathrm{ft^2}$

Step-by-step explanation:

The total surface area simply consists of three rectangles and two triangles. To find the total surface of the figure, find the sum of each of the shapes that make up the outside of the figure:

2 triangles: 2 x 1/2 x 6 x 8 = 48 ft^2

First rectangle: 6 x 12 = 72 ft^2

Second rectangle: 8 x 12 = 96 ft^2

Third rectangle: 10 x 12 = 120 ft^2

*Note: One of the dimensions is in yards, so make sure to convert it to ft (1 yd = 3ft)

Thus, the total surface area of the figure is 48+72+96+120 = 336 ft^2.

A graph is shown below

andrezito [222]

We have that

using a graph tool
see the attached figure

case A) x − 2y > 3
this inequality represented the graph

case B) x − 2y < 3
this inequality not represented the graph

case C) 2x − y > 3
this inequality not represented the graph

case D) 2x − y < 3
this inequality not represented the graph

the answer is
the option A, x − 2y > 3
