It would be answer A since moving it right from the axis makes the x part include a negative next to the number that's being shifted from the axis, and when reflecting it across the x-axis, the number outside of the parenthesis becomes negative
Since the scale factor is greater than 1, this dilation will be an enlargement. Therefore, you multiply 7.2 times 8.1 to get 58.32. This question asks for diameter, so multiply 58.32 times 2 to get 116.64 in.
Answer 16.
Step-by-step explanation:
First you replace the xs with 1/2
(√2•1/2+3)/(6•1/2-5)
Then you solve the multiplications
2•1/2=1
6•1/2=3
Now write them in
(√1+3)/(3-5)
Simplify
(√4)(-2)
Root of 4 equals to
2/-2
And the answer is -1
Answer 17:
Replace x with 8
1/2•8^2-(1/4•8+3)
Solve parenthesis, multiplication first
1/2•8^2-(2+3)
1/2•8^2-(5)
1/2•8^2-5
Solve the 8^2 and the 1/2
1/2•64-5
32-5
The answer is 17
Answer:
Length: 40 Width: 76
Step-by-step explanation:
W is width, and L is length.
We know that the length is 36 less than the width, so L = w - 36. Two times the width plus two times the length equals the perimeter, so set up the equation for the perimeter as:
232 = 2w + 2(w-36)
Now solve for w:
232 = 2w + 2w - 72
304 = 4w
w = 76
we now know that the width is 76, so solve for the length:
L= 76-36
L = 40
