Answer(1):
Given that h(y)=2y-7.
h(8) means plug y=8 into h(y)=2y-7.
h(8)=2*8-7=16-7=9
Hence C) 9 is the final answer.
Answer 2:
(7/8) = (m/32)
to solve for m, we begin by cross multiply
8m=7*32
8m=224
m=28
Hence choice C) 28 is final answer.
Reflection symmetry occurs when a line is drawn to divide a shape in halves so that each half is a reflection of the other.
Rotational symmetry is to check if the given picture is symmetric after some rotation.
Answer 3:
Letter "E" will have
B) the letter has reflection symmetry only
So B) is correct.
Answer 4:
Which statement is true?
Letter "Z" will have
B) the letter has rotation symmetry only
Hence B) is correct.
Answer 5:
Letter "X" will have
A) the letter has both reflection and rotation symmetry
Hence A) is correct.

Answer:
24 ft
Step-by-step explanation:
a^2 + b^2 = c^2
7^2 + b^2 = 25^2
7^2 - 25^2 = -b^2
49 - 625 = -b^2
-576 = -b^2
24 = b

Answer:
Step-by-step explanation:
If it costs $30 to make 6 notebooks then that is $5 for each notebook. So multiply $5 times 50 and you get $250.
