Find real or imaginary solutions of x^4-10x^2=-9

Mathematics
1 answer:
malfutka [58]3 years ago
6 0
This resembles a quadratic and we can factor it using that pattern.

(x^2)^2-(10x^2)+9=0

(x^2-9)(x^2-1)

(x+3)(x-3)(x+1)(x-1)=0

Determine the rate of change for 3/2x -5/4y = 15
Aleksandr-060686 [28]

Answer:

-6/5

Step-by-step explanation:

3/2x - 5/4y = 15

-5/4y = -3/2x + 15

multiply each side by (-4/5)

(-4/5)(-5/4y) = (-4/5)(-3/2x + 15)

y = -6/5x - 12

rate of change: -6/5

The sum of two numbers is 15. four times the smaller number is 60 less than twice the larger number. what is the larger number?
kirza4 [7]
X = smaller number, y = larger number
x + y = 15.....x = 15 - y
4x = 2y - 60

4(15 - y) = 2y - 60
60 - 4y = 2y - 60
60 + 60 = 2y + 4y
120 = 6y
120/6 = y
20 = y <==== larger number is 20

x + y = 15
x + 20 = 15
x = 15 - 20
x = - 5

Lesechka [4]
First, convert how many yards there were to inches. 3 1/2 yards gets you 126 inches. Next, find out how many inches 2 feet and 10 inches of ribbon is. 34 is your answer. Subtract 34 from 126 to get an answer of 92 inches (7 feet, 6 inches.)
