leonid [27]

Well, her initial investment happened at day 0, namely x = 0, let's check,

$\bf M(x)= 4.96(2.18)^x\qquad \boxed{x=0}\qquad M(0)= 4.96(2.18)^0
\\\\\\
M(0)= 4.96(1)\implies M(0)=4.96$

Subtract (5x^2-5) from the sum (x^2-9x+2) and (4x^2-5x+1)

Ivan

Assignment: $\bold{Solve \ Equation: \ \left(x^2-9x+2\right)+\left(4x^2-5x+1\right)-\left(5x^2-5\right)}$

<><><><><><><>

Answer: $\boxed{\bold{-14x+8}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Remove Parenthesis: (a) = a

$\bold{x^2-9x+2+4x^2-5x+1-\left(5x^2-5\right)}$

[ Step Two ] Simplify $\bold{-\left(5x^2-5\right)}$

$\bold{-5x^2+5}$

[ Step Three ] Rewrite Equation

$\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$

[ Step Four ] Simplify $\bold{x^2-9x+2+4x^2-5x+1-5x^2+5}$

$\bold{-14x+8}$

A line has a slope of -4 and passes through the point (0,-6) how do you do this ?

Murrr4er [49]

Answer:

y = -4x-6

Step-by-step explanation:

point slope form

y-y1 = m(x-x1)

y--6 = -4 (x-0)

y+6 = -4(x)

solve for y

subtract 6 from each side

y = -4x-6

I have a bag with blue marbles and yellow marbles in it. At the moment, the ratio of blue marbles to yellow marbles is 8:5. If I

harina [27]

There were 15 blue marbles in the bag before removing some

Let B=blue marbles and Y= yellow marbles

The ratio of B to Y is

$\frac{B}{Y} =\frac{8}{5}$

If we remove 12 blue marbles and add 12 yellow marbles,

the ratio will be

$\frac{B-12}{Y+21} =\frac{1}{3}$

$3(B-12)=1(Y+21)$

$3B-36=Y+21\\$

$3(\frac{8}{5}Y)-36=Y+21$

$\frac{24}{5}Y-Y=21+36$

$\frac{19}{5}Y=57$

$Y=\frac{57*5}{19}\\$

$Y=15$

$B=\frac{8}{5} (15)\\B=24$

Hence, there were 15 blue marbles in the bag before removing some
