5x + 3y = 26 6x + 7y = 21

4 0

So, look. It sorta depends on what the question is asking. Since I only have the equations, and not the question, I'll do my best.

Right, so, if you wanna know the slope and everything, the first equation
5x + 3y = 26 the slope and everything for it, it:
Slope = -3.333/2.000 = -1.667
x-intercept = 26/5 = 5.20000
y-intercept = 26/3 = 8.66667

And the second one 6x + 7y = 21:
Slope = -1.714/2.000 = -0.857
x-intercept = 21/6 = 7/2 = 3.50000
y-intercept = 21/7 = 3

Now, theres also where you just wanna find "x" and "y". Tell me which one you need to know. :)

Answer:

Jenny is wrong the correct answer is x²+ 4 - 4 x.

Step-by-step explanation:

Given that

(x-2)³∕x-2

(x-2)³∕(x-2) =(x-2) (x-2)²∕(x-2)

(x-2)³∕(x-2) = (x-2)²

As we know that

(a-b)² = a²+b² - 2 ab

(x-2)² = x²+ 2² - 2 ˣ 2 ˣ x = x²+ 4 - 4 x

(x-2)² = x²+ 4 - 4 x

It means that

(x-2)³∕(x-2) = (x-2)² = x²+ 4 - 4 x

So Jenny is wrong the correct answer is x²+ 4 - 4 x.

A container ship left port last week caring some good weighing a total of 125,890 tons today I stopped in another port to unload

Answer:

Step-by-step explanation:

You need to be specific. Did the weight decrease by 60 tons or 60 pounds? I assume tons, but in math, you can't assume.

This problem seems overly simple, so I am wondering if some information is missing. With the given information and assuming the decrease was in fact 60 tons, you would have:

125,890 - 60 = 125,830 tons
