Answer:

{ \tt{f(x) = 3x + 1}}

• when f(x) is 7,

{ \tt{3x + 1 = 7}} \\  \\ { \tt{3x = 6}} \\  \\ { \tt{x =  \frac{6}{3} }} \\  \\ { \boxed{ \rm{ \: x = 2 \: }}}

What is the solution of the equation? (√2x-1) + 2=x
Gwar [14]

Answer:

x = 5

Step-by-step explanation:

√(2x − 1) + 2 = x

√(2x − 1) = x − 2

2x − 1 = (x − 2)²

2x − 1 = x² − 4x + 4

0 = x² − 6x + 5

0 = (x − 1) (x − 5)

x = 1 or 5

Check for extraneous solutions.

√(2(1) − 1) + 2 = 1

√(1) + 2 = 1

3 = 1

No solution

√(2(5) − 1) + 2 = 5

√(9) + 2 = 5

5 = 5

x = 5

Marcus ate half of a pizza on Monday night. He then ate one third of the remaining pizza on Tuesday. Which of the following expr
Strike441 [17]

<em><u>Option E</u></em>

<em><u>The expression show how much pizza Marcus ate in total is:</u></em>

Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}

<em><u>Solution:</u></em>

Given that,

Marcus ate half of a pizza on Monday night

He then ate one third of the remaining pizza on Tuesday

Therefore,

Monday\ night = \frac{1}{2}\\

Remaining is given as:

Remaining = 1 - \frac{1}{2} = \frac{1}{2}

He then ate one third of the remaining pizza on Tuesday

Therefore,

Tuesday = \frac{1}{3} \times \frac{1}{2}

<em><u>Thus expressions show how much pizza Marcus ate in total is:</u></em>

Total = monday night + tuesday

Total = \frac{1}{2} + \frac{1}{3} \times \frac{1}{2}

Thus Option E is correct

I need help plz<br> 99 points waiting for the person that answers the question
amid [387]

Answer:

No

Step-by-step explanation:

This is from a website so you might have to rephrase it but Direct variation describes a simple relationship between two variables . We say y varies directly with x (or as x , in some textbooks) if:

y=kx

for some constant k , called the constant of variation or constant of proportionality . (Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x .")

This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.

The graph of the direct variation equation is a straight line through the origin.
