The constant variation of y=15x is 15 and the constant variation of y=8x is 8 :)
<span>When you multiply numbers, two negative signs cancel each other out. Therefore if four of the numbers are negative the product is positive. If either one or three numbers are negative, the product is negative.
1.a negative, b positive, c positive, d positive
2.a positive, b negative, c positive, d positive
3.a positive, b positive, c negative, d positive
4.a positive, b positive, c positive, d negative
5.a positive, b negative, c negative, d negative
6.a negative, b positive, c negative, d negative
7.a negative, b negative, c positive, d negative
8.a negative, b negative, c negative, d positive</span>
Answer:
The anwser is c
Step-by-step explanation:
Answer:
They are similar
Step-by-step explanation:
Answer:
22.14
Step-by-step explanation:
Using the Pythagorean Theorem:
a^2 + b^2 = c^2
21^2 + 7^2 = c^2
441 + 49 = c^2
490 = c^2 (square root both sides so c^2 becomes c)
c = 22.13594363 (round to hundredths)
c = 22.14
