Answer:
A
Step-by-step explanation:
The inverses of functions are basically the Xs and Ys swapped. For example, the inverse of (2,-3) is (-3,2).
Thus, the inverse of (-2,4), (3,2), and (-6,10) will be (4,-2), (2,3), and (10,-6).
the answer is A.
Answer: $37
Step-by-step explanation:
The remaining balance, B (in dollars), on the card after buying x prints is given as $50.00 - 0.15x.
Therefore, the remaining balance on the card if Jane bought 20 prints will be:
= $50.00 - 0.15x.
= $50.00 - 0.15(20)
= $50.00 - $3.00
= $47.00
Answer: 5?
Step-by-step explanation: It says along the tops of the for walls so I'm assuming perimeter. 12+12+10+10 divided by 9.
Answer:
10x
Step-by-step explanation:
The height on the left is the same as the height on the right:
(2x -y) +(y) = (2x)
2x = 2x . . . . . not particularly helpful
The width across the top is the same as the width across the bottom:
3x = (y) +(4x -2y)
y = x . . . . . . . . add y-3x to both sides
The perimeter is the sum of side lengths. Working clockwise from the top, that is ...
P = 3x +2x +(4x-2y) +y +y +(2x -y) = 11x -y = 10x
The perimeter is 10x. (or 10y, if you like)
Answer: y= -4x/3 - 4/3
Step-by-step explanation:
The equation of the line in the slope-intercept form is y=3x4−32.
The slope of the perpendicular line is negative inverse: m=−43.
So, the equation of the perpendicular line is y=−4x3+a.
To find a, we use the fact that the line should pass through the given point: −4=(−43)⋅(2)+a.
Thus, a=−43.
Therefore, the equation of the line is y=−4x3−43.
