Answer:
1003
Step-by-step explanation:
I'll guess P is the perimeter, the sum of the edge lengths.
In centimeters
I get 4 + 4 + 4 + 4 for the sides of the isoscles triangles
5 + 5 + 2.8 + 2.8 for the rectangular base
5 for the apex/top
P = 4+4+4+4+5+5+2.8+2.8+5=36.6 cm
Not sure why the exact answer isn't there, but first choice seem best.
Get packing.
To be perpendicular the product of the two slopes must equal -1.
2m/5=-1
2m=-5
m=-2.5
since y=mx+b we have so far
y=-2.5x+b, using point (-3,4) we can solve for b
4=-2.5(-3)+b
4=7.5+b
b=-3.5 so
y=-2.5x-3.5 We can multiply the whole equation by two so that the coefficients are integers...
2y=-5x-7 add 5x to both sides
5x-2y=-7
Answer:
y-intercept = 3
Step-by-step explanation:
The given equation is :
6x-5y=-15
We can rewrite it ib slope-intercept form as follows :
Dividing both sides by 5
.....(1)
The general equation of slope-intercept form is:
y = mx +c ....(2)
On comparing equation (1) and (2) we get :
m = 6/5
c = 3
Hence, the y intercept of the graph of the equation is 3.
