1. x represents one battery, y represents the other battery
x+y=6.5
x-y=2.5
2. x represents the number of small drinks sold, y represents the number of other size drinks sold
x+y=230
x+1.5y=285
84 is no less than 7 times K, 84 divided by 7= 12,
K=12
Answer:
ALine 1,B neither,CLine 2
Step-by-step explanation:
The answer to 40 is line one. all you have to do is replace x with the first number in the parenthesis and y with the second. In addition remeber that 2 negatives make a positive.
So A: Line 1
B : neither
C: Line 2
hope this helps please tell me if it is correct :)
A linear transformation is a function T:R^n-->R^m that satisfies the following properties
1.T(x+y)=T(x)+T(y)
2.T(ax)=aT(x)
i hoped this helped i honestly tried . let me know if im missing something
Answer:
14/5
Step-by-step explanation:
That " • " signifies multiplication.
g(x) = (x + 1) / (x - 2) and h(x) = 4 - x are to be multiplied together to obtain (g·h)(x):
(x + 1)(4 - x)
(g·h)(x) = --------------------
x - 2
This could be simplified.
But our task is to evaluate this product function at x = -3. So we replace each instance of x with -3:
( -3 + 1 )( 4 - [-3] ) (-2)(7)
(g·h)(-3) = -------------------------- = ----------- = 14/5
-3 - 2 -5
