Answer:

  2

Step-by-step explanation:

The output increases by a factor of 4 when the input increases by 2 units:

  (b^(x+2))/(b^x) = 4 = b^2

  √4 = b = 2

The output value increases by a factor of 2 as each input value increases by 1.

_____

That rate of increase could also be -2. I see nothing in the problem setup that requires the sequence not alternate signs.

What is the value of the function f(x)=10x+2?
Nookie1986 [14]

Answer:

2 if x=0

Step-by-step explanation:

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type.

f(x) = 10x + 2

Replacing f(x) with y

y = 10x + 2

If x = 2,

y = 10(0)+2

y=2

A number is equal to twice a smaller number plus 3. The same number is equal to twice the sum of the smaller number and 1. How m
Pie

Answer:

No solutions exist because the situation describes two lines that have the same slope and different y-intercepts.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to call the numbers x and y.

A number is equal to twice a smaller number plus 3.

Greater number is x, and smaller is y. So

x = 2y + 3

The same number is equal to twice the sum of the smaller number and 1.

This means that x = 2y + 1

Equaling the values for x:

2y + 3 = 2y + 1

0y = -2

y = -\frac{2}{0}

Since division by 0 does not exist, it means that there is no solution for the system.

50 points take it or leave it<br> 3x+4=22
Lerok [7]

Answer:

<h2>X=6</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • equation
  • PEMDAS
<h3>let's solve:</h3>
  1. \sf cancel \: 4 \: from \: both \: sides :  \\  \sf   \implies \: 3x + 4 - 4 = 22 - 4 \\  \implies \sf \: 3x = 18
  2. \sf divide \: both \: sides \: by \: 3 :  \\  \sf  \bcancel \frac{3x}{3}  =  \frac{  \cancel{18} \:  \:  ^{6} }{ \cancel{ \: 3}}  \\  \therefore \rm \: x = 6

Evaluate. 3 to the 3rd power+1⋅9+12 A.24 B.30 C.48 D.264
forsale [732]
Evaluate: 3^{3} + 1 ⋅ 9 + 12&#10; 
First you calculate the exponent: 3^{3} = 27
27 + 1 <span>⋅ 9 + 12
</span>Then you multiply and divide left to right: 1 <span>⋅ 9 = 9
27+ 9 +  12
Then add and subtract: 
27 + 9 + 12 = 48
So the answer to this is 48.
Hope I helped :)
