Answer:

western beach:  y = -2x + 100

dunes beach : y = 5x + 20

set the equations equal to each other

-2x + 100 = 5x + 20

100 - 20 = 7x

80 = 7x

80/7 = x

Kevin is 333 years older than Daniel. Two years ago, Kevin was 444 times as old as Daniel.
tia_tia [17]

Answer: the equations are

k = d + 33

k - 2 = 4(d-2)

Step-by-step explanation:

Let the present age of Kevin be represented by k

Let the present age of Daniel be represented by d

Kevin is 33 years older than Daniel. This means that the expression for their current age is

k = d + 33

Two years ago, Kevin was 4 times as old as Daniel. This means that 2 will be subtracted from their present ages to depict two years ago. Therefore, Two years ago for Daniel will be d-2

Two years ago for Kevin will be k - 2

Remember that Kevin was 4 times as old as Daniel two years ago, it becomes

k - 2 = 4(d-2)

Prove sin^2A + cos^2A = 1
Nady [450]

Step-by-step explanation:

{sin}^{2} A +  {cos}^{2} A  = 1 \\ lhs =  {sin}^{2} A +  {cos}^{2} A  \\  =  {sin}^{2} A +  1 - {sin}^{2} A  \\  = 1 \\  = rhs \\  \therefore \:  {sin}^{2} A +  {cos}^{2} A  = 1 \\
