Write the system of equations in Slope-Intercept Form from the graph below.

Answers

Answer 1

Answer:

y > -2x +3 . . . . line Ay ≤ x . . . . . . . . line B

Step-by-step explanation:

You want the equations for the inequalities shown on the graph.

Line A

The downward sloping dashed line crosses the y-axis at y=3. It has a "rise" of -2 units for each 1 unit to the right. Its slope is rise/run = -2/1 = -2.

The equation for this boundary line can be written ...

y = -2x +3

The graph is shaded above this line, which is not included in the solution. The inequality graphed is ...

y > -2x +3

Line B

The upward sloping solid line crosses the y-axis at y=0 and has a rise of 1 for each run of 1 unit to the right. Its slope is 1/1 = 1, and its y-intercept is 0.

The equation for the boundary line can be written ...

y = 1x +0

The graph is shaded below the solid boundary line, so the boundary is included in the solution. The inequality graphed is ...

y ≤ x

How do you solve this?

Answers

Answer:

4 miles per hour

Step-by-step explanation:

Using division would be the easiest way to solve this problem, since we are finding miles "per" hour.

Knowing that a fish is going 12 miles in 3 hours, we can divide these numbers by each other to find how many miles the fish runs in an hour.

12/3

4 mph

60/15

4mph

it is 4 miles per hour because 12 miles divided by 3 hours is 4 miles per hour and also 60 miles divided by 15 hours is 4 miles per hour

What is Area of Rectangle?

The area of Rectangle is length times of width.

In the given figure there are 3 rectangles.

Area of rectangle is length times width

Length is 5m and width is 4m

Area of rectangle = 5×4

=20 square meters

Area of three rectangles = 3(20)

=60 square meters

There are four right triangles, base is 2m and height is 3.5 m

Area of rectangle = 1/2 × 2× 3.5

=3.5 square meter

As there are 4 right triangles 4(3.5)

Area of 4 right triangles is 14 square meters

Total surface area = 60+14

=74 square meters

Hence, the total surface area of the prism is 74 square meters, Option C is correct.
