Find the zeros of the function by rewriting the function in intercept form

galben [10]

$y=3x^2+2x\\
y=x(3x+2)\\
y=x(x+\frac{2}{3})\\
x=0 \vee x=-\frac{2}{3}\\\\
f(x)=5x^2-25x+30\\
f(x)=5(x^2-5x+6)\\
f(x)=5(x^2-2x-3x+6)\\
f(x)=5(x(x-2)-3(x-2))\\
f(x)=5(x-3)(x-2)\\
x=3 \vee x=2

What is the value of n in this equation 1/2(n-4)-3=3-(2n+3)?

alexdok [17]

Answer:

n = 2

Step-by-step explanation:

Given

$\frac{1}{2}$ (n - 4) - 3 = 3 - (2n + 3)

Multiply through by 2 to clear the fraction

n - 4 - 6 = 6 - 2(2n + 3) ← distribute

n - 10 = 6 - 4n - 6 ( add 4n to both sides )

5n - 10 = 0 ( add 10 to both sides )

5n = 10 ( divide both sides by 5 )

n = 2
