Answer:
the one that looks closest to this
Step-by-step explanation:
Answer:
x=9
y=12
Step-by-step explanation:
you know what the value of x is in terms of the second equation
so put that value into the first equation
so
-5(2y-15) + 4y = 3
-10y + 75 + 4y = 3
-6y + 75 = 3
-6y = -72
y = 12 (now we have the actual value of y, just substitute this into any of the first two original functions)
x = 2(12) - 15
x = 24 - 15
x = 9
Answer:
Step-by-step explanation:
X/8 = 5
X = 40
Adding 1 to the largest number (or any other of the numbers, for that matter) makes the sum 41 and the average 41/8 or 5 1/8.
The answer should be C. 8.0 x 10 *-7
Substitute the f(x) and g(x) following the required operations:
A. (f+g)x = (x^2 + 1) + (x + 1) = x^2 + x + 2
B. (f-g)x = (x^2 + 1) - (x + 1) = x^2 - x
C. (fg)x = (x^2 + 1)(x + 1) = x^3 + x^2 + x + 1
D. (f/g)x = (x^2 + 1) / (x + 1) or x - 1 + 2/(x+1) if answer must be in expanded form
E. (f o g)x = (x+1)^2 + 1 = x^2 + 2x + 2
F. (g o f)x = (x^2 + 1) + 1 = x^2 + 2
