Line segment CD is shown on a coordinate grid:
A coordinate plane is shown. Line segment CD has endpoints 1 comma 2 and 1 comma negative 1.
The line segment is reflected about the y-axis to form C′D′. Which statement describes C′D′?
C′D′ is perpendicular to CD.
C′D′ is half the length of CD.
C′D′ is greater than twice the length of CD.
C′D′ and CD are equal in length.
Answer:
im pretty sure the answer would be C'D' and CD would be equal in length!
Step-by-step explanation:
because you are only reflecting it across the y-axis, no changes will be made to the line itself, only the location of the line :)

Which product is negative? −6⋅(−7)⋅(−8)⋅0 −3⋅(−2)⋅(−4)⋅(−7) −2⋅(−7)⋅12⋅(4) 4⋅(−9)⋅(−3)⋅(−1)
Answer:
Last choice
Step-by-step explanation:
To say it simply if products are in negative or not, we can tell by:-
Looking at negative symbolsThen count how many negative signs are there.If there are even-number signs (2 negative signs, 4 negative signs, etc.) then the product is positive.If there are odd-number negative signs (a negative sign, 3 negative signs, 5 negative signs, etc.) then the product is negative.The only choice that has odd-number negative signs is last choice — othere have 2 or 4 negative signs.
Additionally, keep in mind that:-
positive • positive = positivepositive • negative = negativenegative • negative = positivesame signs multiply each others = same signopposite signs multiply each others = negative (For plus and minus)Above are important fundamental to Algebra and many mathematic courses so you better remember it!

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet?
StartFraction 12 kilometers Over 1 EndFraction times StartFraction 0.62 miles Over 1 kilometer EndFraction times StartFraction 5280 feet Over 1 mile EndFraction = 392,832 feet
Sila put a wrong number in her calculator when multiplying the numerators.
Sila’s first fraction should be StartFraction 1 kilometer Over 0.62 miles EndFraction.
Sila’s last fraction should be StartFraction 1 mile Over 5280 feet EndFraction.
Sila forgot to divide by 0.62.
Answer:
A
Step-by-step explanation:
Sila put a wrong number in her calculator
Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.
Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:
1. Kilometers to Miles:
Start by converting kilometers to miles.
There are 0.62 miles in 1 kilometer.
So, the first fraction is correct:
Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.
2. Miles to Feet:
Next, convert miles to feet.
There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.
Now, let's put it all together:
- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction
Multiply the fractions step by step:
- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile
- This simplifies to 392,832 feet.
So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.
The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.
