Please someone help me and do not just write anything explain thank you . use the information provided to write the vertex form equation of each parabola. y= -2x^2-12x-28 I ended up with (6,-64) is that correct? And remember to add 28 to both sides first PPPPPPPPPPPLLLLLZZZ SOOOOOMMMMONE HEEEELP ME

Answers

ok, so user says that it should be solve for vertex not vertex form
(x,y)
to find the vertex of
y=ax^2+bx+c

the x value of the vertex is -b/2a
the y value is found by plugging in the x value for the vertex back into the original equation and evaluating

y=-2x^2-12x-28
a=-2
b=-12

xvalue of vertex is -(-12)/(2*-2)=12/-4=-3

x value of vertex is -3

plug backin for x
y=-2x^2-12x-28
y=-2(-3)^2-12(-3)-28
y=-2(9)+36-28
y=-18+8
y=-10

yvalue is -10
x value is -3

vertex is (-3,-10)

Is this right and what's the answer for number 3?

Answers

Answer: Hello!

the problems are wrong:

in the first problem, you have 38 rocks, and you can separate them into groups of 10 or in single rocks.

You have 4 options to do it:

0 groups of 10, and 38 single rocks.

1 group of ten and (38 - 19) = 28 single rocks

(this is 10 rocks in the group of then + 28 single rocks = 38 total rocks)

2 groups of ten and (38 - 2*10) = 18 single rocks

3 groups of ten and (38 - 3*10) = 8 single rocks

and you can't form more groups of tens because you only have 8 single rocks left at this point.

in the second problem, the case is the same, now you have 30 pieces of felt and you can divide them into groups of 10 or in single pieces.

then the possible options are:

0 groups of ten and 30 single pieces

1 group of ten and (30 - 10) = 20 single pieces

2 groups of ten and (30 - 2*10) = 10 single pieces

3 groups of ten and (30 - 3*10) = 0 single pieces

in the third problem you need to write, similarly as i did, why you organized the rocks or the pieces as you did.

That looks great! But say you chose number 2. You could say you organized it by multiplying single packs by the pieces of packs.

kedar earns a monthly salary of $2,200 plus a 3.75% commission on the amount of his sales at a mens clothing store. what would he earn this month if he sold $4,500 in clothing? round off to the nearest cent

Answers

$2200 + 3.75% of $4500 would be 2200 + 0.0375 x 4500 or $2200 + $168.75

2200 + 168.75 = $2368.75

Answer:

2368.75 total cost

Step-by-step explanation:

3.75% divided by 100 = 0.0375.

Then 4500 X 0.0375= $168.75.

2,200 + 168.75 = 2,368.75.

= 2,368.75 total cost.
