Answer:

y = 2x - 4

Step-by-step explanation:

Slope intercept form: y=mx+b

m=2

point (2,0) means x=2 and y=0

Plug into the equation:

0 = 2(2)+b

0 = 4+b

b = -4

Resulting equation:

y = 2x - 4

Graph:

Start at origin -4 on y-axis. Since slope is 2/1, rise 2 and run 1 to find the line.

Give three real-world examples of rectangular prisms. Then give two real-world examples of triangular prisms. Explain how you kn
denpristay [2]

Three real world examples of rectangular prisms include juice boxes, cereal boxes, and even cargo containers. Two real world examples of triangular prisms include camping tents and triangular roofs. I chose these objects to represent triangular and rectangular prisms because triangular prisms have two triangular faces and three rectangular faces and rectangular prisms have six rectangular faces.

Sample Response: Boxes, ice cubes, and brick are examples of rectangular prisms. Ramps and tents are examples of triangular prisms. A rectangular prism has six rectangular faces. A triangular prism has two triangular faces and three rectangular faces.

Dom has enough tins of paint to cover a total surface of 280m.
Inessa [10]
So he has to paint 255 m from the 280 m of paint he has
First divide 255/280 to give you a decimal
You should get .9107
Since this is in decimal form (out of 1) you want to get percentage which is out of 100 you multiply by 100
So .9107 times 100
This gives you the percentage which is
91.07%
Now it says round to 1 decimal so it would be
91.1%

Find the equation of line parallel to y=-2x+1 and passing through the point (2,4)
SOVA2 [1]

Answer:

y=-2x+8

Step-by-step explanation:

Hi there!

<u>What we need to know:</u>

  • Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0)
  • Parallel lines always have the same slopes

<u>1) Determine the slope (m)</u>

y=-2x+1

The given line has a slope of -2. Because parallel lines always have equal slopes, we know that the line parallel to this would also have a slope of -2. Plug this into y=mx+b:

y=-2x+b

<u>2) Determine the y-intercept (b)</u>

y=-2x+b

Plug in the given point (2,4) to solve for b

4=-2(2)+b\\4=-4+b

Add 4 to both sides to isolate b

4+4=-4+b+4\\8=b

Therefore, the y-intercept of the line is 8. Plug this back into y=-2x+b:

y=-2x+8

I hope this helps!
