D=dollars earned
T=time spent painting the fence.
(1,5) (2,10) (3,15)
D=5T
Y-5=3-9(y+2). so so u are going to distribute-9 to y and 2 which is -9y-18
so u are going to add like terms 3 and -18 which is -15. so the next step is going to be y-5=-9y-15 so u are going to add 5 to -5 and -15 to balance the equation and u will get -10 . y=-9y -10. since u are multiplying -9 by y so have to expand it y= -9 * y -10. so u have to divide y by y to get y . -9-10= -19 soo y =-19

Let X = smaller
Number. Then, x+4 = larger number
4x = 3(X+4) -3
4X = 3x + 12 - 3
X = 9
Answer:
Step-by-step explanation:
answer is -3 because tan^2 theta-sec^2 theta means -1 and when u multiply -1 and 3 u will get -3.
