3 0

Answer:

y=x^2-9x+18

Step-by-step explanation:

If x1=3 and x2=6, then the equation for the zeroes would be (x-3)(x-6)=0, which can then be expanded to x^2-9x+18=0, making the function y=x^2-9x+18

pshichka [43]

Answer:

\large\boxed{y=(x+5)^2-64}

Step-by-step explanation:

\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\h=\dfrac{-b}{2a},\ k=f(h)\\\\\text{We have the equation:}\ y=x^2+10x-39\to x=1,\ b=10,\ c=-39.\\\\\text{Substitute:}\\\\h=\dfrac{-10}{2(1)}=\dfrac{-10}{2}=-5\\\\k=f(-5)=(-5)^2+10(-5)-39=25-50-39=-64\\\\\text{Finally:}\\\\y=1(x-(-5))^2-64=(x+5)^2-64

If 3x+2=5/9, what is the value of −3x+8?<br><br>Group of answer choices
allsm [11]

Answer:

= 4

Step-by-step explanation:

first lets find the value of x in 3x+2=5/9

3x+2=5/9

3x = \frac{5}{9} -2

3x = \frac{3}{9}

3x = \frac{1}{2}

x = \frac{1}{2 * 3\\ }

x = \frac{1}{6}

\frac{1}{6} can also be written as 6^{-1}

−3x+8

-3 (\frac{1}{6}) +8

\frac{-3}{6} +8

= 4
