Answer:x=-7+1/2

Step-by-step explanation:You move all terms to the left: x-15/2-(2x)=0

then add all the numbers together, and all the variables:-1x-15/2=0

You multiply all the terms by the denominator:-1x*2-15=0

Multiply elements:-2x-15=0

You move all terms containing x to the left, all other terms to the right-2x=15

x=15/-2

x=-7+1/2

Answer:

10th term of the sequence = 0.537

Step-by-step explanation:

First three terms of the sequence are → 5, 4, $\frac{16}{5}$ ..........

Ratio of 2nd and 1st term of the sequence = $\frac{4}{5}$

Ratio of 3rd and 2nd term of the sequence = $\frac{\frac{16}{5} }{4}$

= $\frac{4}{5}$

Therefore, ratio between every successive term to the previous term is common.

Common ratio 'r' = $\frac{4}{5}$

First term of the sequence 'a' = 5

nth term of a geometric sequence = $a(r)^n$

Therefore, nth term of the given term will be $T_n=5(\frac{4}{5})^n$

Now we have to find the 10 term of the given sequence.

For n = 10,

$T_{10}=5(\frac{4}{5})^{10}$

= 0.53687

≈ 0.537

Therefore, 10th term of the sequence is 0.537

The value of x and y which satisfies the equation : <br>9x+-5y=-34<br>

jarptica [38.1K]

Answer:
x=1
y=8.6

Explanation:

first start by assigning a random value to a random variable, let’s say x=1

from there the equation becomes solveable

9x1+-5y=-34
simplify
9-5y=-34
-9 from both sides
-5y=-43
divide both sides by-5
y=8.6

hope this helps :)

Can y’all solve this one

Soloha48 [4]

(f g)(x) means f(x) * g(x), so plug the value of each function in:

(x+2)(x-4)

And solve by distributing using FOIL:

Firsts: x * x = x²

Outers: x * -4 = -4x

Inners: 2 * x = 2x

Lasts: 2 * -4 = -8

Combine them all together:

x² - 4x + 2x - 8

Combine like terms (the -4x and 2x):

x² - 2x - 8

So the second to last one is correct.
