Answer:
(-1, -3)
Step-by-step explanation:
We suppose your notation means you want to reflect given point P across the horizontal line y=1.
The x-coordinate will remain the same.
The new y-coordinate will be such that y=1 is the midpoint between the original and its reflection:
(5 + y)/2 = 1
5 + y = 2 . . . . multiply by 2
y = 2 -5 = -3 . . . subtract 5
The reflected point is (-1, -3).
___
The same sort of math applies whenever you have a midpoint and want to find the other end point. Double the midpoint value and subtract the end point you have in order to find the other end point.
Answer:
She did better on the Math test.
Step-by-step explanation:
14/17 is 82 percent, and 31/19 is only about 80%.
Answer:
Firstly, we'll apply the below identity.
Applying the above identity.
⇒ (√5 + √2)²
⇒ (√5)² + (√2)² + 2×(√5)×(√2)
⇒ 5 + 2 + 2√10
⇒ 7 + 2√10
Comparing the LHS and RHS
⇒ 7 + 2√10 = a + b√10
∴ a = 7 and b = 2.
The expanded form of a number involves rewriting the number
The expanded form of 239238 is 13291 * 3 * 3 * 2
<h3>How to write the number in an expanded form</h3>
The number is given as: 239238
Express as a product of 2
239238 = 119619 * 2
Express as a product of 3
239238 = 39873 * 3 * 2
Further, expand
239238 = 13291 * 3 * 3 * 2
The number cannot be further expanded.
Hence, the expanded form of 239238 is 13291 * 3 * 3 * 2
