Which value for x makes the sentence true?

Mathematics
1 answer:
Illusion [34]3 years ago
7 0

Answer:

D

Step-by-step explanation:

Given

- \frac{2}{5} + x = \frac{8}{3}

Add \frac{2}{5} to both sides

x = \frac{8}{3} + \frac{2}{5}

Before adding the fractions we require them to have a common denominator

Multiply the numerator/ denominator of the first fraction by 5 and

Multiply the numerator/ denominator of the second fraction by 3

x = \frac{8(5)}{3(5)} + \frac{2(3)}{5(3)}

  = \frac{40}{15} + \frac{6}{15}

Now add the numerators leaving the denominator

x = \frac{40+6}{15} = \frac{46}{15} → D

if you have 89 apples and you take 72 away and buy 14 more and take 12 away then buy 42 more and give them 16 more
Delicious77 [7]

Answer:

The correct answer is that there will be 45 remaining apples.

Step-by-step explanation:

So, you start off with 89 and then you take 72 away, that leaves you with 17 apples. Then, you buy 14 more which brings it up to 31. After that, you give 12 more away which brings your total down to 19. Next, you go out and buy 42 more, which adds up to  61 remaining apples. Finally, you give away 16 more, which brings you to a grand total of, 45 apples left.

Hope this helps!

Square ABCD was translated using the rule (x, y) → (x – 4, y + 15) to form A'B'C'D'. What are the coordinates of point D in the
Vitek1552 [10]

Answer:

D = (13, - 23 )

Step-by-step explanation:

Given the translation rule

(x, y ) → (x - 4, y + 15 )

To go in the reverse direction, that is image to original, then, reverse the operations in the translation rule.

(x , y ) → (x + 4, y - 15 ) , thus

D'(9, - 8 ) → D(9 + 4, - 8 - 15 ) → D(13, - 23 )

Consider the triangle.
mr Goodwill [35]

For this case we observe that the three angles of the triangle are equal. Also, we have by definition:

A triangle is equilateral, when the three sides have the same length (in addition, the three internal angles measure 60 degrees or\frac {\pi} {3}.

Answer:

The three sides have the same length

Find the inverse of the relation?
melisa1 [442]
The inverse....switch ur x's and y's...

inverse :
domain is { -2,2,4,4,5} ...notice u have 2 "x" values that are 4
range is {-3,0,2,3,4}

The relation DOES NOT represent a function. A function will not have any repeating x values. It can have repeating y values, just not the x ones.

Now the relation would be a function...but the inverse is not

4tan^2 x-8tanx+3=0 on interval [0,2pi]
Vadim26 [7]
\bf 4tan^2(x)+8tan(x)+3=0\qquad [0,2\pi ]
\\\\\\
\textit{since it's just a quadratic, we'll just factor it}
\\\\\\\
[2tan(x)+1][2tan(x)+3]=0\implies 
\begin{cases}
2tan(x)+1=0\\
\qquad tan(x)=-\frac{1}{2}\\
\qquad \measuredangle x=tan^{-1}\left( -\frac{1}{2} \right)\\
\qquad \measuredangle  x\approx 333.4^o, 153.4^o\\
2tan(x)+3=0\\
\qquad tan(x)=-\frac{3}{2}\\
\qquad \measuredangle x=tan^{-1}\left(-\frac{3}{2}  \right)\\
\qquad \measuredangle x\approx303.7^o, 123.7^o
\end{cases}
