Which of these steps will eliminate a variable in this system? 4x-9y=8 2x+3y=24
For eliminate a variables we need addition method or elimination method.
Define the term Variable?In an equation or formula, a variable is a symbol or letter that stands in for an unknowable or varying quantity or value.
We can multiply the second equation by -2, so that the coefficient of x in both equations will be the same but with opposite signs:
⇒ 4x - 9y = 8
⇒ -4x - 6y = -48
Add the two equations together: ⇒ -15y = -40
⇒ y = 8/3
Substitute this value of y back into either equation to solve for x.
⇒ 4x - 9(8/3) = 8
⇒ 4x - 24 = 8
⇒ x = 8
Therefore, the steps to eliminate a variable in this system using the addition method are to multiply the second equation by -2, add the two equations together to eliminate the x variable, solve for y, and then substitute that value back into either equation to solve for x.

You have $150 in a savings account and you have some cash. The tape diagram represents the ratio of the amounts of money. You want to have twice the amount of money in your savings account as you have in cash. How much of your cash should you deposit into your savings account?
Answer: $200
Step-by-step explanation:
We know that:
You have $150 in a savings account.
This is represented with two tiles.
Then each tile represents:
$150/2 = $75
And in cash you have 5 tiles, then in cash you have:
5*$75 = $375.
Then the problem is:
You have $150 in the savings account
You have $375 in cash.
You want to deposit a quantity such that you have twice the amount of money in your savings account as you have in cash.
Suppose that you move a quantity X from cash to the savings account, then now we have the situation:
Sav. Acc. = $150 + X
Cash = $375 - X
And we want that:
Sav. Acc. = 2*Cash
($150 + X) = 2*($375 - X)
Let's solve this for X.
$150 + X = $750 - 2*X
3*X = $750 - $150 = $600
X = $600/3 = $200
You should deposit $200 in the Savings acount.
Tape diagrams are used to represent numbers as a ratio
$200 from the cash should be deposited into the savings account
Represent the amount in the savings account with s, and the cash with c.
So, we have the following ratio from the tape diagram
[tex]\mathbf{s : c = 2 : 5}[/tex]
You have $150 in the savings account.
So, the ratio becomes
[tex]\mathbf{150 : c = 2 : 5}[/tex]
Express as fractions
[tex]\mathbf{\frac c{150}= \frac 52}[/tex]
Multiply both sides by 150
[tex]\mathbf{c= \frac 52 \times 150}[/tex]
[tex]\mathbf{c= 375}[/tex]
Let the deposited amount be x.
Twice the amount in the savings account as cash means that:
[tex]\mathbf{150 + x = 2 \times (375 - x)}[/tex]
Open brackets
[tex]\mathbf{150 + x = 750 - 2x}[/tex]
Collect like terms
[tex]\mathbf{2x + x = 750 - 150}[/tex]
[tex]\mathbf{3x = 600}[/tex]
Divide both sides by 3
[tex]\mathbf{x = 200}[/tex]
Hence, $200 from the cash should be deposited into the savings account

The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use this formula to find the curvature function of the following curve. f(x)=−5x2 The curvature function is κ(x)=nothing.
Answer:
K(x) = [tex]\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }[/tex] ( curvature function)
Step-by-step explanation:
considering the Given function
F(x) = [tex]-5x^2[/tex]
first Determine the value of F'(x)
F'(x) = [tex]\frac{d(-5x^2)}{dy}[/tex]
F'(x) = -10x
next we Determine the value of F"(x)
F"(x) = [tex]\frac{d(-10x)}{dy}[/tex]
F" (x) = -10
To find the curvature function we have to insert the values above into the given formula
K(x) [tex]= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }[/tex]
K(x) = [tex]\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }[/tex] ( curvature function)
