What are the zeros of the function f(x) = x2 + 8x + 4, expressed in simplest radical form?

Katyanochek1 [597]

Answer:

Step-by-step explanation:

assuming it is $x^{2} +8x+4$

Using Quadratic formular -

a - 1

b - 8

c - 4

$x= \frac{ -8 -,+ \sqrt{(8^2) - 4 (1)(4)}}{2(1)} \\\\$

$x = \frac{-8 +,- \sqrt{48} }{2}\\\\$

$x = \frac{-8+,- 4\sqrt{3} }{2}$

$x = {-4+,- 2\sqrt{3} }$

PLZ HELP NEED ASAP, much appreciated

Margaret [11]

Answer:

Ok that's not it

x=-1 then y=4

x=0 then y= 6

x=1 then y = 8

x=2 then y= 10

x=3 then y= 12

Step-by-step explanation:

when y=2x+6

you have to plug what it says x is in each of the equations.

For the first one it says x=-1

you then plug that in and you get y=2(-1)+6

then you go through PEMDAS and first you get y=-2+6

-2+6 = 4

therefore y=4

and you just go through the rest wiht that

Resolver la siguiente ecuación por eliminación o sustitución: a-8b= -9 a-2b= -7

Crazy boy [7]

Answer: Solution: $a=\dfrac{-19}{3}$ and $b=\dfrac{1}{3}$ .

Step-by-step explanation:

The given pair of equations:

$a-8b= -9\ ...(i)\\\\ a-2b= -7\ ...(ii)$

Eliminate equation (i) from (ii) , we get

$-2b-(-8b)=-7-(-9)\\\\\Rightarrow\ -2b+8b=-7+9\\\\\Rightarrow\ 6b=2\\\\\Rightarrow\ b=\dfrac{1}{3}$

Put value of b in (ii) , we get

$a-2\times\dfrac{1}{3}=-7\\\\\Rightarrow\ a=-7+\dfrac{2}{3}\\\\\Rightarrow\ a=\dfrac{-21+2}{3}\\\\\Rightarrow\ a=\dfrac{-19}{3}$

Solution: $a=\dfrac{-19}{3}$ and $b=\dfrac{1}{3}$ .

The sum of two consecutive odd integers is 188. list the numbers from smallest to largest:

mixer [17]

X and x+ 2 equal 188
add all the like terms to get 2x+2=188
subtract 2 from each side
2x=186
divide by 2
x=93
so the numbers are 93 and 95
