The zeros of a quadratic function are 4 and 8. What is the axis of symmetry of the function?

PLS HELP AND IF YOU COULD SHOW UR WORK IT WOULD HELP A LOT <33

Answers

Answer 1
So if you want to have a factored form...

If the zeroes are +4 and +8, you would write
(X-4) (x-8)
Then you would multiply it out to get to quadratic form...

So, (x-4)*(x-8)
X^2 - 12x + 32

Then you would plug it into the formula for axis of symmetry...
X= -b/2a

X=12/2 = 6


X=6

1) b (think commutative and associative properties) , 2) a (think that minus a negative equals positive)

Answer:

1.)d. (because if you search up -14-8 then you get 22 which is same as d.)

2.)a.

Answers

x=y-bm is the answer you are looking for
y = mx + b

y - b = mx + b - b (Subtract b from both sides this cancels out b on right side)

y - b / m = xm/m (Divide m on both sides this cancels out m on right side)

x = y - b / m (Final answer)

Mateo and Tyrone collect baseball cards. Mateo has 27 pages in his binder with 9 cards on each page. If the boys have a total of 748 cards, which equation represents the number of baseball cards that Tyrone has?
A.(27x9)+748=c
B.(27x9)+c=748
C.(27 divided by 9)+748=c
D.(27 divided by 9)+c=748

Answers

The answer is B: (27x9)+c=748

Answer:

The answer would be B

Step-by-step explanation:

You would have to multiply 27 x 9 to get a total of 243. Then, You can subtract 748 - 243 (But since that's not an option, B would be the answer because it's basically the same total you get.)

Hope it helps! :D

Terri is trying to save $250 so she can buy a new surfboard . She has \$75 saved already and plans to save $45 per week . How many weeks will it take her to save up enough money to purchase a new surfboard ?

Answers

Answer:

It will take Terri 4 weeks to save up enough money for a new surfboard.

Step-by-step explanation:

250-75= 175

175/45= 3.888

But its asking for whole weeks, so round to the nearest whole number, which is 4.

btw 45x4= 180 so she'll have 5 extra dollars.

$250=$75+$45 •x
x= number of weeks
250=75+45•x
75+45•x=250
45•x=250-75
45•x=175
x=175/45
x=3.88
Terri needs to save money for at least 4 weeks.
4•45=$180
$180+$75=$255
