Answer:
11
Step-by-step explanation:
x= -b/2a
x= -8/2(-2)
x=-4/-2
x=2
f(2) = -2(2) +8(2)+ 3
f(2) = -8 +16 + 3
f(2) = 11
Maximum value is 11
Answer:
11
Step-by-step explanation:
it has a vertex at (2,11)
.
f(2) = 11
how to find the vertex;
function equation is f(x) = ax^2 + bx + c
we can find x by :-b/2a, -8/-4 = 2
and by putting the x value we get the y
f(2) = 11

What is an equation of the line that passes through the points (-6, 2) and (6, –2)?
Answers
Answer:
y=(-1/3)x
Step-by-step explanation:
y=mx+b
(x,y)
put in the first point into y=mx+b
2=m(-6)+b
then the second point is (6,-2)
put the point into y=mx+b
-2=6m+b
----------------------------
Put both equations in a system of equations
-2=6m+b
2=m(-6)+b
solve for m and b
-1/3=m and 0=b
so put that back into y=mx+b
y=(-1/3)x+0
so that is the only line that passes through both points
Which best describes the probability of the rolling a 7 on a number cube that is numbered from 1 through 6
Answers
Answer:
[tex]\huge\boxed{\text{Impossible}}[/tex]
Step-by-step explanation:
To find the probability of something happening, we find all the outcomes that can happen, find all the outcomes in which our criteria is met, and set that up as a fraction, where it's criteria met/total possible outcomes.
When we roll a 6-sided die, we will have 6 possible outcomes that we can roll.
1, 2, 3, 4, 5, and 6.
We can not roll anything except these 6! Since a die only has 6 sides, numbered 1-6, we will only roll these numbers.
7 is not in this list! It is impossible to roll a 7 on a die that only has 6 sides. Since 7 isn't even possible, it would be impossible to get a 7 on a 6-sided die.

Answers
Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

so the sum will be 8x and the product
will be 15.In the product part look for a no
that when you multiply it by another no
it will give you 15 by when you add it will
become 8.The no.is 5 and 3.you now rewrite the equation x^2+3x+5x+15=0
you now simply the equation x(x+3)+5(x+3)

7) $2600
8) d = 36 in
9) h= 1176 m
Step-by-step explanation:
5) r=v/r
r= 15,600 gals ÷ 390 mins
r= 40 gals/min
6) r=v/t
r= 1000mm ÷ 8 hrs
r= 125 mm/hr
7) $4500 - $1900 = $2600
8) C = Pi x d

Get the center and radius from the graph.
Center is: (-3, 6)Radius is: 2Use the circle formula:
(x - h)² + (y - k)² = r²We have:
h = -3, k = 6, r = 2Substitute and get the equation:
(x - (-3))² + (y - 6)² = 2² ⇒(x + 3)² + (y - 6)² = 4Correct choice is C

WHOEVER ANSWERS IS CONSIDERED THE BRAINLIEST QUESTION: Faye has a bag that contains 10 red, 13 blue, 16 white, 10 green, and 11 black marbles. She pulls a marble out of the bag without looking. What is the probability Faye pulls out a white marble.
SHOW WORK!
Answers
Answer:
Faye's probability of pulling out a white marble is 3/80.
Step-by-step explanation:
To find the probability, we must first add everything up. 10 + 13 + 16 + 10 + 11 = 60 marbles. Now we divide 60 by the amount of white marbles there are. 60 ÷ 16 = 3.75% or 3/80. Therefore, the probability of Faye pulling out a white marble is 3/80.
