Answer: j=t^2+5
Step-by-step explanation:
Answer: The numbers are: <u>x = 34, y = 12</u>
Step-by-step explanation:
Lets say the numbers are x and y. The two equations are:
x+y=46
x= 3y-2
Next you use substitution for x in the first equation which brings you to
3y-2 + y = 46 which simplyfies to:
4y - 2 = 46
4y = 48
48 / 4 = 12
y = 12
Then you plug back y=12 in either of the equation to solve for x:
x = 3y - 2
x = 3(12) - 2 = 36 - 2 = 34
x = 34, y = 12
Answer:
1
Step-by-step explanation:
Cosine = adjacent/hypotenuse
Cos A = 3/4.24
Cos B = 3/4.24
Since they are equivalent, Cos A/Cos B = 1
