You need to substitute the y for 32 and multiply the -5 by the -7. I got 32=37.
Answer:
y= -3x + 14
Step-by-step explanation:
m=-3
x=4
Y=2
Y=mx+b
2=-3(4)+b
2=-12+b
You add +12 in both side and you get
14=b
To find the probability of landing on a triangle, you will want find the combined areas of the triangles and the total area of the square target.
Divide the area of the combined areas and the total area to find the probability of landing on a triangle.
A = 1/2bh
1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)
A = bh
26 x 26
A = 676 square inches
128/676 = 0.189
There is an approximate probability of 0.19 of hitting a triangle.
The questions ask you to caculate how many elements must a set of numbers of proper subsets of the set 1/2 of the total number of subsets per a subset,base on the question I bet the answer is 1 I hope this helps let me know if u passed and I will try to work it out again GREAT LUCK!!
Answer: Hope this helps.
