So since you know that this is a line you can use the slope intercept form which is y=mx+b. M being the slope and B being the y intercept. So for 5a. It is asking for the equation so you just plug in the numbers into y=mx+b.

y=5x-2

For 5b all you have to do is plug in 0 for y in the equation above.

So it will be 0=5x-2. So you simplify it.

Subtract 2 to both sides and you get -2=5x

THen divide by 5 on both sides to isolate the x and so you will get -2/5 =x.

So the answer would be the value of x when y is 0 is -2/5

I really hope that this helped you in some way. If you have any questions feel free to ask me. Have a great day :)

Find the surface area of the rectangular prism. 5ft tall 5 feet long 2 feet wide

Mars2501 [29]

Answer:

46.25 feet squared

Step-by-step explanation:

base area = 5x2 = 10

you need to find how tall the faces of the prism are now. You can do this using the pythagorean theorem: a^2+b^2=c^2

5^2+2.5^2=c^2 and 5^2+1^2=c^2

(since it is a rectangular pyramid)

c= 5.60 and c= 5.01

now be can find the surface area of the 4 triangles

SA= 5.60x2 and SA= 5.01x5

SA=11.2 and SA= 25.05

add all the components (11.2, 25.05, 10) together to get the final surface area: 46.25
