What does it mean to say we have a base ten system? Be specific. Use examples.
NeTakaya

Answer:

This means that the decimal system is responsible for representing quantities using ten different digits.

Step-by-step explanation:

This means that the decimal system is responsible for representing quantities using ten different digits: 0 (zero), 1 (one), 2 (two), 3 (three), 4 (four), 5 (five ), 6 (six), 7 (seven), 8 (eight) and 9 (nine).

The digits acquire their value according to the relative position they occupy. This position, in turn, depends on the base in question. It has the powers of the number ten as a base. Thus: 10 raised to 0 is equal to 1; 10 raised to 1 is equal to 10; 10 raised to 2 equals 100; etc.

The number 123, for example, has three figures. In the decimal system, it is constructed as follows, respecting the corresponding positions:

(1 x 10 raised to 2) + (2 x 10 raised to 1) + (3 x 10 raised to 0)

(1 x 100) + (2 x 10) + (3 x 1)

100 + 20 + 3

123

As you can see, from right to left, the first place corresponds to the unit (10 raised to 0), the second place corresponds to the ten (10 raised to 1) and the third place corresponds to the hundred (10 raised to 2 ).

Hope this helps!

Determine the solution x^2 - 3x -28 ≥ 0
IgorC [24]

x^2 - 3x -28 ≥ 0

factor

(x-7) (x+4) ≥ 0

x=7  x=-4

we have three regions where the answers can lie

x<-4  between -4 and 7  and x>7

pick a point and see if it works

x=-10

(-10-7) (-10+4) ≥ 0

negative * negative  is greater than 0 so this is a solution   x< -4

x=0

(0-7) (+4) ≥ 0

negative * positive  is less than 0 so this is  not a solution  

x=10

(10-7) (10+4) ≥ 0

positive * positive is greater than 0 so this is a solution   x>7

We have two regions that work

x<-4 and x>7

Is it possible for an exponential equation to have no solutions? If so, give an example. If not, explain why.
vredina [299]
A function f(x) has solutions if we can find a value to plug in that leads to 0. In other words, there are solutions to f(x) = 0. Another term for "solution" is "root" or "x intercept"

An exponential function may cross the x axis at one point only. Though there are plenty of cases when there are no solutions at all. For instance, in the case of f(x) = (2^x) + 10

The right hand side will never be equal to zero no matter what you plug in for x. The graph will never cross the axis.

To answer your question, yes it is possible to have an exponential equation to have no solutions.

Write the equation of each line in slope intercept form (If possible please show work)
kow [346]

Answer:

y = -2/3x-9

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b where m is the slope and b is the y intercept

y = -2/3x+b

We have a point we can substitute into the line

-5 = -2/3(-6)+b

Subtract 4 from each side

-5-4 =4+b-4

-9 =b

y = -2/3x-9
