Answer:

The first term is 80 and the common ratio is 2.5 because every term is being multiplied by 2.5.  to figure this out when it is not obvious, divide the 2nd term by the first term.  the equation is   y = 80(2.5)^x

Solve on the interval 0,2pi) 2cscx-3=-5
nydimaria [60]
We have that

<span>2cscx-3=-5---------> 2cscx=-5+3---------> cscx=-2/2---------> cscx=-1

we know that
csc x=1/sin x
then
1/sin x=-1--------------> sin x=-1
x=arcsin (-1)---------> x=-90</span>°
x=-90°---------------> 360°-90°-----------> x=270°------------> 3pi/2<span>

the answer is
x=3pi/2 radians

One number is six times another number. Their difference is 35. What are the two numbers?
konstantin123 [22]









x - y = 35
x = 6y
Plug 6y in for x in the first equation.
6y - y = 35
5y = 35
Divide both sides by 5
y = 7
x = 6y
x = 6(7) = 42
42 and 7
Letter C
Since we had the answers we could have just tried the answers but you will not always have multiple choice so this is the method for solving.
