Set each answer up equal to the question, solve and see if the two numbers you end up with are equal, if not try the next answer!
c = -8 which means whenever you see a c replace it with -8
d = 2 means the same for 2
and cd means c times d
so
cd + d
is
(-8)(2) + (2) =
-16 + 2 = -14
Answer:
- m = -3/4
- y-intercept = 399
- slope-intercept equation: y = -3/4x + 399
Step-by-step explanation:
It can be easiest simply to solve the equation for y.
3x + 4y = 1596
4y = -3x + 1596 . . . . subtract 3x
y = -3/4x + 399 . . . . divide by 4
From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.
Answer:
x
Step-by-step explanation:
If both the function and its inverse exist, then the composition of the function with its inverse is just 'x.'
For this problem plug in the given x and y values:
For the first one: No
