If the coefficient of x^2 is negative, the graph will be n shaped and curve down instead of like a u shape if it was positive. If the vertex is below the x axis and curves down, it won’t pass the x axis, Tia is right.
The equation of a line which has the slope m and passes through the point A(x1,y1) has the formula:
y-y1=m(x-x1)
in your case m= -5 ; A(x1;y1)=(1;-1)
y-(-1)= -5(x-1)
y+1= -5(x-1)
answer is c
Hi lovely,
The answer you're looking for is 21.
You made the choice to choose the letter A, a second time.
(9.69-9.58):9.58*100 =
(9.69:9.58-1)*100 =
101.14822546973-100 = 1.1
Eso sería una disminución de 1.1
O como porcentaje redondeado 1.14%.
Espero eso ayude!
