Answer:
Step-by-step explanation:
x = larger number, y = smaller number
x + y = 57
x = 2y - 3
2y - 3 + y = 57
3y - 3 = 57
3y = 57 + 3
3y = 60
y = 60/3
y = 20 <=== the smaller number
x = 2y - 3
x = 2(20) - 3
x = 40 - 3
x = 37 <=== the larger number
Original line equation: y=-4x+4
Perpendicular lines have opposite reciprocals, so the slope of the perpendicular line would be 1/4x.
Perpendicular line equation: y=1/4x+b
Plug in the coordinates that the line passes through to solve for b. Plug -8 in for x and 2 in for y.
2=1/4(-8)+b
Multiply.
2=-2+b
Add 2 to both sides.
4=b
Equation of the perpendicular line: y=1/4x+4
Hope this helps! :)

B. Every year the coin is worth 3 more dollars.
X=-4 is the answer for this question
Answer:
Step-by-step explanation:
Finding an equation of a tangent line to that function requires that we find the derivative of the function at that point. Since this is an absolute value function with its cusp at (2, 5), the function is not differentiable here.
