Writing in Math. Explain how the digit 7 can have different values.

1 answer:

6 0

The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.

Which graph shows the solution to the equation below? log3(x+2) = 1

sdas [7]

Refer the attached figure of the graph (Option A) that shows the solution to the given equation

Step-by-step explanation:

The given logarithmic equation is

$\log _{3}(x+2)=1$

The solution to this logarithmic equation is where the graph of

$y=\log _{3}(x+2)$

When comparing above with the given equation, we find that y = 1.

Now, find the 'x' value by using this. So, applying log base 3 rule on right side, we get as below,

$x+2=3^{1}$

x = 3 - 2 = 1

Plot the asymptote and the point (1 , 1). Sketch the log curve using those two reference facts. Hence, concluded the graph in option A as solution to the given equation.

10. Your Turn: Find the equation of a line that is perpendicular to y=2x+7, and passes through the point (-4, 7). SHOW YOUR WORK

agasfer [191]

Alright, so since the slope of the perpendicular line is -1/(slope), we get (-1/2)=-1/2 and y=(-1/2)x + something. Plugging 7 in as y and -4 in as x, we get 7=(-1/2)(4)+something (let's make it a variable b), and multiplying it out we get 7=-2+b. Adding 2 to both sides, we get 7+2=9=b, so the perpendicular line equation is therefore y=(-1/2)x+b

Answer:

1 = Given

2 = Addition Property of Equality

3 = Division Property of Equality

Step-by-step explanation:

1 = Given

[] The problem gives us this equation

2 = Addition Property of Equality

[] We add 2x to both sides, which is the addition property of equality

3 = Division Property of Equality

[] We divide both sides of the equation by 6, which is the division property of equality
