Answer: y= -13/25x
Step-by-step:
Using (50,-26) and -13/25
You put it in the equation y=mx+b which would be -26 = -13/25 (50) +b
Then you simplify to find b which would be 0
so the answer would be y = -13/25x
Hope this helps :^
Answer:
x = 20
y = 50
Step-by-step explanation:
10x + 2y = 300 | ×2 |
8x + 4y = 360 | ×1 |
20x + 4y = 600
8x + 4y = 360
_____________--
12x = 240
x = 240/12
x = 20
10x + 2y = 300
10(20) + 2y = 300
200 + 2y = 300
2y = 300 - 200
2y = 100
y = 100/2
y = 50
Lets first divide the deck into shapes, in this case, we will have three.
The first shape, will be the rectangle that represents the lower portion of the deck. Its' dimensions are 12ft x 33ft. 396 Square ft.
Next lets do the upper rectangular section. It has the dimensions of (22ft-12ft)*24ft. 240 Square ft.
Third, we have the last remaining shape, the right triangle. Its' dimensions are 1/2(22ft - 12ft)*(33ft - 24ft). 45 Square ft.
Finally! We can now add the three areas together to get the full figure.
396 Square ft + 240 Square ft + 45 Square ft = 681 Square ft!
Answer:
Step-by-step explanation:
Given is a point (3,7,-5)
We have to find the distance from
(a) The xy-plane
=Distance here would be z coordinate = |-5|=5
(b) The yz-plane
=Distance here would be x coordinate = |3|=3
(c) The xz-plane
=Distance here would be y coordinate = |7|=7
(d) The x-axis
Here y =0 z=0
So distance would be
(e)The y -axis
(f) The z-axis
