Rewrite the function by completing the square (vertex form)<br><br> f(x)=x^2+16x-46
insens350 [35]

Answer:

\large\boxed{f(x)=(x+8)^2-110}

Step-by-step explanation:

\text{The vertex form of equation}\ y=ax^2+bx+c:\\\\y=a(x-h)^2+k\\\\\text{We have the equation:}\\f(x)=x^2+16x-46=x^2+2(x)(8)-46=x^2+2(x)(8)+8^2-8^2-46\\\\\text{use}\ (a+b)^2=a^2+2ab+b^2\to x^2+2(x)(8)+8^2=(x+8)^2\\\\f(x)=(x+8)^2-64-46=(x+8)^2-110

Solve the system of equations below 4x+y=16 and 2x+3y=-2
astraxan [27]
4x+y=16 multiply both sides by -3 and will get 
2x+3y=-2

-12x -3y = -48
   2x +3y = -2
--------------------------
-10x  0  = -50

-10x = -50

x = -50/(-10) = 5

x = 5 

4x+y=16
4*5+y=16
20+y=16

y = 16-20

y = -4

x = 5
y = - 4

hope helped

A jar contains 46 quarters and pennies. The total value of the coins is $4.30. Which system of equations can be used to find p,
Crazy boy [7]

Answer:

16 quarters

30 pennies

Step-by-step explanation:

q= quarters

p=pennies

set up a system of equations. One equation is for total value, the other is total # of coins.

q + p = 46

0.25q + 0.01p = 4.30 -> multiply this equation by 4 so you can subtract from the top equation

q + P =46

1q + 0.04p = 17.20

subtract the bottom equation from the top

0.96p = 28.8

divide by 0.96

p=30

substitute p in the top equation

q + 30 = 46

subtract 30 from both sides

q = 16
