If Sadie earns $11.25 per hour, her earnings will vary directly with the number of hours that she has worked per week.
If she made $146.25 in a work week, she worked 13 hours.
13 hours x 11.25 = 146.25
Hint: "4x 2 - 25 = 0" is nearly meaningless. You want 4x^2 - 25 = 0.
Note that both 4x^2 and 25 are perfect squares, so this is the difference of two squares, and is equal to (2x-5)(2x+5)= 0.
Answer:
y=-2x+3
Step-by-step explanation:
the points of intersect are (0,3) and (2,-1) then i made it into slope
3+1/0-2
4/-2
-2
substitute (0,3)
3=b
y=-2x+3
Answer:
I think b no. is the correct answer
