30/40 say no, so x/1000 would say no. 1000/40=25, 25*30=750. So, about 750 would dislike it.
Step-by-step explanation:
x²+4-4x+y²=3
x²+y²-4x+1=0
X = 2 expand the brackets and then collect like terms (x's on one side) and then dived to get x on its own! :)
Answer:
She will have $71.32.
Step-by-step explanation:
135-(44.8+18.88)=71.32
Answer:
If we used the quadratic formula to solve the equation we can say:
-b = -5
b² - 4ac = 13
2a = 2
Solving the first and last equations we get b = 5 and a = 1. Substituting these values into the second equation we get:
25 - 4c = 13
Solving this we get c = 3 so the answer is x² + 5x + 3.
