Standard form: ax+by=c
With standard form there are a few rules One being ax and by cannot be fractions. Two being ax has to be positive.
Now ill explain the problem.
y=-1/2x-5 ↔ You will need to multiply the whole problem by 2 which will leave you will this 2y=-2x-10
Next you will need to move x over to the y side which will look like this 2x+2y=-10 (your answer)
Now you might be asking where the - went that was in front of the x term. Another rule is when you move across the equal sign you change the sign.
Let me know if this helped!
Answer:
closest choice: (-2, 0.2)
Step-by-step explanation:
The attached image from a graphing calculator shows the solutions (to the nearest tenth) to be ...
(-1.9, 0.2)
(1.0, 6.0)
The closest of the offered choices is (-2, 0.2). None are actually correct.
Anonymous's answer is completely correct. I thought this problem was asking how to find the distance along the function from the point (2,2^8), and wrote the answer to that nice, tasty problem.
Simply integrate the line element with respect to some affine parameter!
<span><span>L=<span>∫10</span><span><span><span><span>(<span><span>∂x</span><span>∂λ</span></span>)</span>2</span>+<span><span>(<span><span>∂y</span><span>∂λ</span></span>)</span>2</span></span><span>−−−−−−−−−−−−−</span>√</span>dλ</span><span>L=<span>∫01</span><span><span><span>(<span><span>∂x</span><span>∂λ</span></span>)</span>2</span>+<span><span>(<span><span>∂y</span><span>∂λ</span></span>)</span>2</span></span>dλ</span></span>
In this case,
<span><span>x(λ)=λ(X−2)+2,</span><span>x(λ)=λ(X−2)+2,</span></span>
<span><span>y(λ)=(λ(X−2)+2<span>)8</span>.</span><span>y(λ)=(λ(X−2)+2<span>)8</span>.</span></span>
<span>Note that this approach can also solve the original problem, with some simplification.</span>
The formula is
A=p (1+r/k)^kt
A future value?
P present value 120
R interest rate 0.86
K compounded monthly 12
T time 21 year
A=120×(1+0.86÷12)^(12×21)
A=4,510,568,953.1372
