Answer:
y = -2x + 8/5
Step-by-step explanation:
Answer:
x. = sqrt 6 and x = - sqrt 6
Step-by-step explanation:
x^4 + 2x^2-48=0
(x^2 - 6) (x^2 + 8) = 0
x^2 - 6 = 0
x = + sqrt 6 and x = - sqrt 6
x^2 + 8 = 0
x^2 = sqrt -8 (a negative number doesn’t have a real square root)
Answer:
3a +16b
Step-by-step explanation:
Use the distributive property to eliminate parentheses:
7a +10b -4a +6b
Group like terms, if you need to:
(7a -4a) +(10b +6b)
Simplify each group:
3a +16b
Lets say that x is the amount in dollar that both Elijah and his sister spent on the snacks in the movie
The equality would be :
2x = 34 - (2 * 9.50)
2x = 34 - 19
2x = 15
x = $ 7.5
