Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

Answer:
I make it 6 cm diameter (well....5.97 cm really, but it depends how many places you take π to!).
Explanation:
You have been given density (d) and mass (m), so first you can determine volume (v).
<span>d=<span>m/v</span></span> therefore <span>v=<span>m/d</span></span> = <span>3000/2.33</span> = 1287.55 <span>c<span>m^3</span></span>
Now you have the volume and the length (L) from which you can work out the cross sectional area, <span>π.<span>r2</span></span>, and from that the diameter.
Volume v =<span>π.<span>r2</span>.L</span> therefore r = <span>√<span>v/<span>π.L</span></span></span> and diameter D = 2r = <span>√(<span>v<span>π.L)</span></span></span>x 2.
So plugging in the numbers gives: D = <span>√(<span>1287.55/<span>3.142X46)</span></span></span> X2 = 5.97 cm.

Answer:
Answer:4.8 monthsStep-by-step explanation:First, let's write down the information that we are given.Plant A: Initial Height: 3 in.Constant Rate of Growth (CRG): 2in/month (2 inches per month)Plant B:Initial Height: 1 in.CRG: 29in/year (29 inches per year)We can see that Plant B grows 29 inches per year, so lets convert Plant B's 'CGR' to months.Plant B - Divide by 12 (12 months in a year)29/12 in/yearNow, Lets put these into equations:Plant A: y = 2x + 3Plant B: y = 29/12 x + 1Now, set these two equations together and solve for x.2x + 3 = 29/12 x + 12 = 5/12 x4.8So, after 4.8 months, the plants will be the same height.
hope it helps you
