equations.

a. Equation 1 y=2x+1
Equation 2 y=-3x-3
Point (-0.8,-0.6)

b. Equation 1 x+y=3
y+2=X
Equation 2

Point (13,2)

C. Equation 1 x+y = 9
Equation 2 0.3x+0.6y = 4.5

Point (0,9)

Samantha is growing a garden in her back yard. she spend $90 setting up the garden bed and buying the proper garden supplies. in addition, each seed she plants cost $0.25. a. write the function f(x) that represents samantha's total cost on her garden. b. explain what x represents. c. explain what f(x) represents. d. if samantha plants 55 seeds, how much did she spend in total?

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.

Can someone, me with this.i really need with this
