Answer:
Right triangle
Step-by-step explanation:
Using pythagorean theorem,

Hence satisfied. So it is right triangle.
Answer:
The equation is 4y+8=9
The expression is 3-2
The inequality is 7/y < 6
Step-by-step explanation:
Answer:
a - (6-9)
Hopefully this is correct
Step-by-step explanation:
Y=7x+1
*note that the first number is always the x.
so,
a) (0,?)
y=7(0)+1
y=1
(0,1)
b) (3,?)
y=7(3)+1
y=21+1
y=22
(3,22)
The two-way table is attached.
We know that 63 people took the survey, and 22 of them were left-handed. This means that 63-22=41 of them are right handed.
Out of the 63 total, 37 are left brain dominant; this means that 63-37=26 are right brain dominant.
Of the 26 that are right brain dominant, 21 are right handed; this means 26-21=5 are left handed.
Of the 22 left-handed people, 5 are right brain dominant; this means 22-5 = 17 are left brain dominant.
Of the 37 left brain dominant people, 17 are left handed; this means 37-17=20 are right handed.
