Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{m = 140}}}}}$

Step-by-step explanation:

$\sf{1.9m + 14 = 2m}$

Move 2m to right hand side and change it's sign

Similarly, move 14 to left hand side and change it's sign

$\dashrightarrow{ \sf{1.9m - 2m = - 14}}$

Collect like terms

$\dashrightarrow{ \sf{ - 0.1m = - 14}}$

Divide both sides by -0.1

$\dashrightarrow{ \sf{ \frac{ - 0.1m} { - 0.1} = \frac{ - 14}{ - 0.1}}}$

Calculate

$\dashrightarrow{ \sf{m = 140}}$

Hope I helped!

Best regards! :D

Which function can be used to model the graphed geometric sequence?

andreev551 [17]

Answer: The correct option is 1, i.e., $f(x+1)=\frac{5}{6}f(x)$ .

Explanation:

The geometric sequence is in the form of,

$a,ar,ar^2,ar^3,....$

Where, a is the first term of the sequence and r is the common ratio of the sequence.

It means the $n_{th}$ term of the sequence is defined as,

$a_n=ar^{n-1}$

So the the $(n+1)_{th}$ term of the sequence is defined as,

$a_{n+1}=ar^n$

$a_{n+1}=r(ar^{n-1})$

$a_{n+1}=ra_n$

It means the geometric sequence is in the form of,

$f(x+1)=rf(x)$

Where, r be any constant.

From the options only $f(x+1)=\frac{5}{6}f(x)$ is in the form of $f(x+1)=rf(x)$ with common ratio $\frac{5}{6}$ .

Therefore, the function can be used to model the graphed geometric sequence is $f(x+1)=\frac{5}{6}f(x)$ .

Chocolates costing $8 per pound are to be mixed with chocolates costing $3 per pound to make a 20 pound mixture. If the mixture

rewona [7]

put the amount of $8 a pound chocolate as say it as x
As the total number of pounds is 20
so the amount of $3 a pound chocolate must be <span>20−x
so it will be</span>.
8x + 3(20 - x) = 5(20)
so correct option is C
hope it helps
