Answer:
Step-by-step explanation:
<u>Given </u>
<u>Perimeter of a square is:</u>
<u>Substitute the value:</u>
Something to the second power is simply that number multiplied by itself once. The third power is something multiplied by itself 2 times, and so on
To be perpendicular, the slope of the new line has to have the reciprocal of the original slope.
Do this by flipping the slope (ifi t's a whole number make it a fraction) and change the sign.
3 ⇒ -1/3
Input x and y and solve for b.
5 = -1/3(-6) + b
Simplify.
5 = 2 + b
Subtract 2 from both sides.
3 = b
y = -1/3x + 3
Answer:
19. Opposite of a Difference ↔ E. -(8 - 3·m) = 3·m - 8
20. Opposite of a sum ↔ A. -[(-r) + 2p] = -(-r) - 2p
21. Opposite of an Opposite ↔ F. -1[ -1(9 - 2w)] = 9 - 2w
22. Multiplication by 0 ↔ B. 160 - (3d + 2)(0) = 160 - 0
23. Multiplication by ↔ D. -1 -(4r + 3s) + t = (-1)(4r + 3s) + t
21. Distributive property ↔ C. 5(2 - x) = 10 - 5x
Step-by-step explanation:
19. Opposite of a difference is the difference of the opposites
20. Opposite of a sum is the sum if the opposites
21. Opposite of an opposite is the original number
22. Multiplication by 0- The result of multiplication by 0 is 0
23. Multiplication by -1 results in the change in sign of a number
24. Distributive property - Multiplying the sum or difference of two numbers by a number, will have the same result as multiplying each each of the addends by the number individually and adding the product together.
The negative means it is a decrease.
0.12 x 100 = 12%
Her weight decreased 12%
Answer: B
