Draw a line on y=-2 and reflect the dot on the other side. The x doesn’t change, only y changes. So only option is (2,1).

Point x is located at ( 2,5)

When reflecting across the y axis the x value remains the same.

The reflection is at y -2, from -2 to the location of z (-5) is a difference of 3 units.

Add 3 to the reflection line -2 + 3 = 1 , the new y value would be 1.

Answer:

a) 8/11 x 5/3

b) It will be positive. When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

Step-by-step explanation:

a) -8/11 / -3/5

1) -8/11 ÷ (-3/5)

Write the complex fraction as a division expression. Use parentheses because our second fraction is a negative.

2) 8/11 ÷ 3/5

When we have an even number of negatives, the result will be positive ( (-) + (-) = +).

3) 8/11 x 5/3

Dividing is the same as multiplying the second part of the fraction flipped.

4) 40/33

Multiply them: 8 x 5 / 11 x 3

Since the question wants you to write as a multiplication expression, this is the answer:

8/11 x 5/3.

Answer:

Step-by-step explanation:

When you have a coefficent in front of a logarithm function, you can take the argument to the power of that coefficient. For example, the 3 in front of the logarithm can be brought into the argument, and you can take 'x' to the third power. You get:

[tex] log_{4}( {x}^{3} ) = log_{4}(32) + log_{4}(2) [/tex]

When you add logarithms, it is equivalent to multiplying their arguments:

[tex]log_{4}( {x}^{3} ) = log_{4}(32 \times 2) = log_{4}(64) [/tex]

Since both sides are log base 4, the arguments must equal each other:

[tex] {x}^{3} = 64[/tex]

[tex]x = \sqrt[3]{64} = 4[/tex]

here it is, this is ur answer x=4

The range Girls Choose


The mean Choose.​

Answers

Answer:

Range

The range of the data is the difference between the largest data value and the smallest data value.

Therefore, the ranges are:

Boys:  10 - 3 = 7

Girls:  9 - 5 = 4

So the boys have a larger range than the girls.

Mean

To calculate the mean, add up all the data values then divide by the number of values.

[tex]\textsf{Mean of Boys}=\dfrac{3+6+7+7+8+8+8+8+9+10}{10}=\dfrac{74}{10}=7.4[/tex]

[tex]\textsf{Mean of Girls}=\dfrac{5+6+6+6+7+7+7+8+8+9}{10}=\dfrac{69}{10}=6.9[/tex]

So the boys have a higher mean than the girls.

2 |3x-5| - 4 = 12

Show work

Answers

Isolate the absolute-value term:

2 |3x - 5| - 4 = 12

2 |3x - 5| = 8

|3x - 5| = 4


Recall the definition of absolute value:

[tex]|x| = \begin{cases}x & \text{if }x \ge0\\-x&\text{if }x<0\end{cases}[/tex]

We consider two cases:

• If 3x - 5 ≥ 0, then |3x - 5| = 3x - 5, and the equation resolves to

3x - 5 = 4

3x = 9

x = 3

• Otherwise, if 3x - 5 < 0, then |3x - 5| = -(3x - 5) = -3x + 5, hence

-3x + 5 = 4

-3x = -1

x = 1/3
