How do you solve the system: y+1=2x 5y+5=10x

Marta_Voda [28]

Answer:

choose "infinitely more solutions"

Step-by-step explanation:

Let's solve this system by substitution method

y+1=2x

- 1 = - 1

y = 2x -1 <-- sbstitute this in the next equation

---------------------------------------------------------------------------------

5y+5 = 10x

5(2x -1) + 5 = 10x

10x -5 + 5 = 10x

10x + 0= 10x

- 10x = -10x

0 = 0 <-- infinitely more solutions

Which ratio is equivalent to 3/7? A) 6 to 10 B) 9:12 C) 12/35 D) 7 to 3

Leona [35]

we are ratio as

$=\frac{3}{7}$

It will be equivalent to only those terms which would be multiple of this term

so, we will multiply top and bottom term by 5

and we get

$=\frac{3\times 5}{7\times 5}$

$=\frac{15}{7\times 5}$

$=\frac{15}{35}$

so, it is very similar to 12/35

so, it will be equivalent to 12/35

so, option-C.......Answer

Answer:

$a_n = 3 ({5})^{n - 1}$

Step-by-step explanation:

The given sequence is 3,15,75,375,...

The first term of this geometric sequence is

$a_1=3$

The common ratio is

$r = \frac{15}{3} = 5$

The explicit formula is given by:

$a_n = a_1 {r}^{n - 1}$

We plug the first term and common ratio into the formula to get:

$a_n = 3 ({5})^{n - 1}$
