Y = -4*6^(x-1). This is a geometric sequence, so you need a common ratio and a first term. The first term in this sequence is -4, and the common ratio is 6, so you will get this.

Solve the equation 7/z-1 = 9/z+4
algol [13]

Answer:

z is equal to 18.5

Step-by-step explanation:

When an equation is in the format a/b = c/d, the quickest way to simplify it is to cross multiply.  Each side is multiplied by the other sides denominator, eliminating the division:

\frac{7}{z-1} = \frac{9}{z + 4}\\7(z + 4) = 9(z - 1)\\7z + 28 = 9z - 9\\7z - 9z = -9 - 28\\-2z = -37\\z = 37/2\\z = 18.5

So z is equal to 18.5

If u want u can answer question 14 and 15 but if u don’t just answer 14
natali 33 [55]

Answer:

For #14, (around) 108 times.

#15 = 53

Step-by-step explanation:

14)

2.69*10^5 = 269000

2.5*10^3 = 2500

269000/2500 = 107.6

Rounding up, we get 108

15)

√(53 - 8)2 + (31 - 3)2

= √(45)2 + (28)2

= √2809

= 53
