Answer:
(4, -6)
Step-by-step explanation:
A reflection across the y-axis means the point is equal but opposite distance from the y-axis. It begins at 4 units to the LEFT (negative) of the y-axis, so after the reflection, it should be 4 units the the RIGHT (positive) of the y-axis. This has no change on the y-value of the point, because no matter the y-value, the point will still be the same distance from the y-axis. Long story short, if you're reflecting across the y-axis, change the sign of the x-coordinate. If you're reflecting across the x- axis, change the sign of the y-coordinate. That's why the answer is (4, -6).
Answer:
He should have divided 12 ÷ 3 first.
Step-by-step explanation:
Following PEMDAS/BODMAS, the first step is solving equations in parentheses. Since the parentheses contain a multi-step equation, Jay needs to follow PEMDAS for inside the parentheses as well. Instead of adding 3+12 first, he should have done division first (12 ÷ 3).
How the problem should be solved:
-3 × (3 + 12 ÷ 3) - 4
-3 × (3 + 4) -4
-3 × 7 - 4
-21 - 4
-25
The volume of a rectangular prism or cube is: Length × Width × Height
In this case,
- the length of the prism is 2 feet
- the width of the prism is 1.5 feet
- the height of the prism is 1.5 feet
Multiply the above to find the volume: 2 × 1.5 × 1.5 = 4.5 ft³
Keep in mind that volume is represented in cubic units!
Answer:
The earth is bigger
Step-by-step explanation:
The Earth is bigger than the sun, because 1 million earths can fit inside the sun.
