Answer:
im sorry i cant help you without a picture
Step-by-step explanation:
To get -4 from 1, we must either subtract 5 from 1 or mult. 1 by -4. Unfortunately subtracting 5 from -4 does not result in 9, and mult -4 by -4 does not result in -16. So neither "works" in predicting the next term.
Can you think of any other experiments to do that would help you discover the pattern 1, -4, 9, -16?
81 inches converted to feet is 6.75 feet
Answer:
Step-by-step explanation:
Let x represent the number of stamps from Europe.
Let y represent the number of stamps from Africa.
Let z represent the number of stamps from Asia.
She has 47 stamps in all. This means that
x + y + z = 47 - - - - - - - - - - - 1
The number of African stamps is 2 times the number of Asian stamps. This means that
y = 2z
She has 20 stamps from Europe. Therefore, substituting x = 20 and y = 2z into equation 1, it becomes
20 + 2z + z = 47
3z = 47 - 20 = 27
z = 27/3 = 9
y = 2z = 2 × 9
y = 18
She has 20 stamps from Europe, 18 stamps from Africa and 9 stamps Asia.
Y = -2x - 2...the slope here is -2. A parallel line will have the same slope.
y = mx + b
slope(m) = -2
(4,5)...x = 4 and y = 5
now we sub and find b, the y int
5 = -2(4) + b
5 = -8 + b
5 + 8 = b
13 = b
so ur parallel equation is : y = 2x + 13
