A bag contains 40 red and green marbles. The number of green marbles, g, is 9 times the number of red mapples, . How many red ma

marin [14]

Answer:

Step-by-step explanation:

You need to try out all the numbers.

lets start with 4

if there where 4 red marbles then there would be 9 times as many marbles

so 4 x 9 = 36

Now we add and see if the sum is 40

36 + 4 = 40

We got it on the first try

You can use the same method on more problems like these.

Hope this helps :)

Help Please I dont even know what to do :(

Answer:

(a). Function 1

(b) Function 2

Step-by-step explanation:

Find the equation for all functions;

function 1: y= 2x+1

function 2: y= -2x+3

function 3: y= 5x-2

function 4: y= -4x-4

for answer of (a) y= mx+c

c is intercept. so function 1 has closest intercept to 0

for (b) the greatest y intercept is function 2

for(c) slope is m: we have function 1, 2 and 4

1. What is the vertex form of the equation?

sergeinik [125]

1.vertex form is $y=a(x-h)^2+k$

to get into vertex form, complete the square

$y=-x^2+12x-4$

step 1: group x terms

$y=(-x^2+12x)-4$

step 2: factor coefient in front of x^2 term

$y=-1(x^2-12x)-4$

prep for next step: take 1/2 of linear (1st dgree term) and square it

$\frac{-12}{2}=-6$ , $(-6)^2=36$

step 3: add positive and negative of that previous number inside the parenthasees

$y=-1(x^2-12x+36-36)-4$

factor perfect squaer trionmial

$y=-1((x-6)^2-36)-4$

take out that -36 by expansion

$y=-1(x-6)^2+36-4$

$y=-1(x-6)^2+32$

2. factor out the 2

$2(x^2+8x+12)$

what 2 numbers multiply to get 12 and add to get 8?

2 and 6

$2(x+2)(x+6)$

for $ax^2+bx+c=0$

$x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}$

in our case

$x^2-7x-6=0$

a=1, b=-7, c=-6

$x=\frac{-(-7) \pm \sqrt{(-7)^2-4(1)(-6)}}{2(1)}$

$x=\frac{7 \pm \sqrt{73}}{2}$

so $x=\frac{7+\sqrt{73}}{2}$ and $x=\frac{7-\sqrt{73}}{2}$

4. remember that $i=\sqrt{-1}$ so $i^2=-1$

treat $i$ as a variable

$(-2i)(8i)=$

$(-2)(i)(8)(i)=$

$(-2)(8)(i)(i)=$

$(-16)(i^2)=$

$(-16)(-1)=$
