Answer:
4x + 5y = 15
-4x + y = 7
6y = 22
y = 22/6 = 11/3
-4x + 11/3 = 21/3
-4x = 10/3
x = -40/3
Step-by-step explanation:
To solve this we would need to find 2/3 of 864. To make this simpler we can convert 2/3 into decimal form which can be found by dividing 2 by 3. This equals 0.6. Now we simply multiply 864 by 0.6 to get 518.4, if that is needed as a fraction it would be 518 2/5
Answer:
see below
Step-by-step explanation:
f(x) = 5x^3 +1, g(x) = – 2x^2, and h(x) = - 4x^2 – 2x +5
f(-8) = 5(-8)^3 +1 = 5 *(-512) +1 =-2560+1 =-2559
g( -6) = -2 ( -6) ^2 = -2 ( 36) = -72
h(9) = -4( 9)^2 -2(9) +5 = -4 ( 81) -18+5 = -324-18+5=-337
Answer: 10
Step-by-step explanation:
9 1/6 x 1 1/11
55/6 x 12/11
cross reduce
5/1 x 2/1
10
This expression is factored completely. However, if we foil, we can make it to it's original expression.
When you foil, you get:
Simplify.
