How many solutions are there to the equations 5x+1=3x+7?

Answers

5x + 1 = 3x + 7

Subtract 3x to both sides:

2x + 1 = 7

Subtract 1 to both sides:

2x = 6

Divide 2 to both sides:

x = 3

So this equation only has 1 solution.

$5x+1=3x+7\n2x=6\nx=3$

Which of the following describes a one-to-one function?

Answers

Option C) is correct.

Step-by-step explanation:

One to one function can be checked by using horizontal line test and vertical line test.

A) $y = \left | x \right |$

the graph of this function ia attached below named as Graph 1.

The above function did not pass the horizontal line test therefore it is not a one to one function.

$\rm B) \;y = \left\{\begin{matrix}4 & , & x<0\n 5 & , & 0\leq x\leq 2\n 6 & , & x > 2\end{matrix}\right.$

the graph of this function is attached below named as Graph 2.

The above function did not pass the vertical line test therefore it is not a one to one function.

$\rm C)\;y = \left\{\begin{matrix}5x-1 & , & x<-2\n x-9 & , & x \geq -2\n \end{matrix}\right.$

the graph of this function is attached below named as Graph 3.

The above function pass the horizontal line test as well as vertical line test and therefore this function is one to one function.

$\rm D)\; y=[[x]]$

the graph of this function ia attached below named as Graph 4.

The above function is a floor function and fail the vertical line test.

Therefore, correct answer is option C).

check the picture below.

bearing in mind that a one-to-one function must pass the horizontal line test as well as the vertical line test.

now, |x| is the graph of a letter V more or less, and that'd fail the horizontal line test.

the first piecewise function, has say 4 : x < 0, namely for all values before 0, "y" is a steady constant of 4, that will be a horizontal line and will definitely fail the vertical line test.

[[x]] is pretty much the "floor function", and you can do a quick google search on it, or do it in your calculator, it should have a floor function, but that one will definitely fail the vertical line test as well.

According to the table, the die was rolled 40 times:

10+6+4+8+6+6=40

odds of rolling a 2 were 6/40 and the odds of rolling a 4 were 8/40

P(2)=6/40

P(4)=8/40

P(2 or 4)=6/40+8/40=14/40 when simplified, its 7/20

7/20=0.35 or 35%

Answer= 7/20 or 35%

Make the following changes to the number 7.849: make the 7 worth 1/10 as much.

Answers

Answer:

The change applied to 7.849 is to multiply it by 0.1 to get 0.7849.

Step-by-step explanation:

We need to make 7 in 7.849 worth $(1)/(10)$ .

Now, $(1)/(10)$ = 0.1

Thus, to make 7 in 7.849 worth 0.1, we multiply the number by 0.1

i.e. 7.849 × 0.1 = 0.7849

Hence, the change applied to 7.849 is to multiply it by 0.1 to get 0.7849.

So you want 7 to be 1/10 of much. Pretty easy. All you need to do is change 1/10 into a decimal by dividing.

1 ÷ 10 = 0.1

Now you multiply 7 and 0.1

7 × 0.1 = 0.7

So your answer is 0.7!
