Pls help -10y + 18 = -3(5y - 7) + 5y what is y?

You find yourself with 17 guilders( a gold coin) but you are planning on taking a trip to a country where the local currency is

3241004551 [841]

We are given

The current exchange rate is 2 guilders for every 3 florins

so,

2 guilders = 3 florins

now, we can find for 1 guilders

so, we get

$1guilders=\frac{3}{2} florins$

now, we can multiply both sides by 17

$17\times 1guilders=17\times \frac{3}{2} florins$

now, we can simplify it

$17guilders=25.5florins$

so, option-A........Answer

which of the binomials below is a factor of this trinomial? x^2 + 5x - 36 A. x - 5 B. x - 9 C. x + 9 D. x^2 + 5

<h3>Answer: C. x+9</h3>

===============================================

Explanation:

Think of two numbers that multiply to -36 and also add to 5. Put another way: think of two factors of -36 that add to 5.

Those two numbers are 9 and -4 since

9 times -4 = -36

9 plus -4 = 5

So we have x^2 + 5x - 36 factor into (x+9)(x-4)

x+9 is one factor

x-4 is the other factor

-------

Alternatively, you can use a graphing tool to locate the x intercepts, and that will in turn lead to the factorization. Or you could use the quadratic formula to get the job done. Completing the square is yet another tool to use. So there are multiple approaches.
