Answer:

Sample Response: The goal is to get x alone on one side of the equals sign. First, isolate the variable by applying the subtraction property of equality to subtract 1/2x from both sides. Next, find a common denominator to combine like terms. Then use inverse operations to multiply both sides by the reciprocal of the fraction coefficient. The result will be x = 16. Finally, check the solution by substituting 16 for x in the original equation.

Step-by-step explanation:

58x = 12x + 2

58x -12x = 2

46x = 2

x = 2/46 = 0.434

Answer: 22

Step-by-step explanation:

28 + 7 + 6 + 3 = 44

then multiply it and you end up with 44 over 2 and then you divide it, which is 22!

your answer would be 22.

-- first, do what is in the parenthesis

28 plus 7 is 35; 35 plus 6 is 41; 41 plus 3 is 44.

-- second, 1/2 is another word for splitting in half or dividing by 2. SO, do 44 divided by 2. you get 22.

Answer:

The correct answer option is D. [tex]10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}[/tex].

Step-by-step explanation:

We are given the following expression:

[tex] \left ( \sqrt { 10 x ^ 4 } -x \sqrt { 5 x ^ 2 } \right ) \left ( 2 \sqrt { 15 x ^ 4 } + \sqrt { 3 x ^ 3 } \right ) [/tex]

Assuming that [tex]x\geq 0[/tex], we are to find its simplified product.

[tex] \left ( \sqrt { 10 x ^ 4 } -x \sqrt { 5 x ^ 2 } \right ) \left ( 2 \sqrt { 15 x ^ 4 } + \sqrt { 3 x ^ 3 } \right ) [/tex]

[tex]\\\\ = 2 \sqrt { 150 x ^ 8 } + \sqrt { 3 0 x ^ 7 }-2x\sqrt{75x^6}-x\sqrt{15x^5} \\\\ =2\sqrt{25\times6x^8}+x^3\sqrt{30x}-2x\sqrt{25\times3x^6}-x^3\sqrt{15x} \\\\ =10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}[/tex]

The simplified product is:

       [tex]10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}[/tex]

The expression is given by:

[tex](\sqrt{10x^4}-x\sqrt{5x^2})(2\sqrt{15x^4}+\sqrt{3x^3})[/tex]

Now we know that:

[tex]\sqrt{x^2}=x\\\\and\\\\\sqrt{x^4}=\sqrt{(x^2)^2}=x^2[/tex]

Hence, we get the expression as follows:

[tex](\sqrt{10x^4}-x\sqrt{5x^2})(2\sqrt{15x^4}+\sqrt{3x^3})=(x^2\sqrt{10}-x\cdot x\sqrt{5})(2x^2\sqrt{15}+x\sqrt{3x})[/tex]

Now, we will use the property that:

[tex](a+b)(c+d)=a(c+d)+b(c+d)[/tex]

Hence, we have the expression as:

[tex]=x^2\sqrt{10}(2x^2\sqrt{15}+x\sqrt{3x})-x^2\sqrt{5}(2x^2\sqrt{15}+x\sqrt{3x})[/tex]

[tex]=2x^4\sqrt{10}\sqrt{15}+x^3\sqrt{10}\sqrt{3x}-2x^4\sqrt{5}\sqrt{15}-x^3\sqrt{5}\sqrt{3x}[/tex]

Now we know that:

[tex]\sqrt{a}\sqrt{b}=\sqrt{ab}[/tex]

i.e. we have:

[tex]=2x^4\sqrt{150}+x^3\sqrt{30x}-2x^4\sqrt{75}-x^3\sqrt{15x}\\\\=2x^4\sqrt{5^2\cdot 6}+x^3\sqrt{30x}-2x^4\sqrt{5^2\cdot 3}-x^3\sqrt{15x}\\\\=10x^4\sqrt{6}+x^3\sqrt{30x}-10x^4\sqrt{3}-x^3\sqrt{15x}[/tex]

Answer:

[tex]\large\boxed{f^{-1}(x)=\dfrac{1}{2}x-\dfrac{1}{2}}[/tex]

Step-by-step explanation:

[tex]f(x)=2x+1\to y=2x+1\\\\\text{exchange x to y and vice versa:}\\\\x=2y+1\\\\\text{solve for y:}\\\\2y+1=x\qquad\text{subtract 1 from both sides}\\\\2y=x-1\qquad\text{divide both sides by 2}\\\\y=\dfrac{x-1}{2}=\dfrac{1}{2}x-\dfrac{1}{2}[/tex]

2. if a bird is a cardinal, it is red

A conditional statement is a statement that can be written in the form “If P then Q,” where P and Q are sentences.

Given:

Exercise makes you healthier.

So, we have to write in the form of if- then statement

Answer:  The radius of the given circle is 4 units.

Step-by-step explanation:  We are given to find the radius of the circle with the following equation :

[tex]x^2+y^2-10x+6y+18=0~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

We know that

the standard equation of a circle with center at the point (h, k) and radius r units is given by

[tex](x-h)^2+(y-k)^2=r^2.[/tex]

From equation (i), we have

[tex]x^2+y^2-10x+6y+18=0\\\\\Rightarrow (x^2-10x+25)+(y^2+6y+9)-25-9+18=0\\\\\Rightarrow (x-5)^2+(y+3)^2-16=0\\\\\Rightarrow (x-5)^2+(y-(-3))^2=4^2.[/tex]

Comparing it with the standard equation, the radius of the circle is given by

[tex]r=4.[/tex]

Thus, the radius of the given circle is 4 units.

Answer:

"It is translated 1 unit left and stretched vertically by a factor of 3"

Step-by-step explanation:

The parent function here is y = x^2

Let's give out some general rules of transformation:

If y = f(x) is a parent function, then

1. If we have y = a * f(x)

| a | > 1 is a stretch;  

0 < | a | <1 is a compression, vertically for both

and

2. If we have y = f(x-c), this means horizontal translation to right c units and y = f(x+c) means horizontal translation c units left

Looking at y = 3(x+1)^2, we can say that "it is vertical stretch by a factor 3 and horizontal translation 1 units left"

Answer: C is correct, No solution

Step-by-step explanation:

Let’s simplify the second equation,

8x-4y=-20

We can divide the whole equation by 4...

8x/4-4y/4=-20/4

Which becomes....

2x-y=-5

Now let’s move things around to see if it’s the same equation as the one on top...

-y=-2x-5

y=2x+5

Now we need to solve the systems...

y=2x-5

y=2x+5

Since their slopes are both 2 and their y-intercepts are not identical, the answer is no solution. The two lines will continue on without ever crossing because they have the same slope.

The solution set for the given system of linear equations is -

(2.5, 0).

A function is a relation between a dependent and independent variable. We can write the examples of function as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to find the number of solutions that the given linear system of equations have -

y = 2x - 5

- 8x - 4y = -20

We will solve the given system of equations using the method of substitution. We can write -

y = 2x - 5

- 8x - 4y = - 20

- 8x + 20 = 4y

y = - 2x + 5

Now -

2x - 5 = - 2x + 5

4x = 10

x = 2.5

and -

y = 2 x 2.5 - 5

y = 0

Therefore, the solution set for the given system of linear equations is -

(2.5, 0).

Answer:

Minimum = 50

First Quartile = 80

Median = 135

Third Quartile = 165

Maximum = 200

Step-by-step explanation:

First, it is important to reorder our values into ascending order:

50, 60, 100, 130, 140, 150, 180, 200

You've correctly identified the minimum, median and maximum values, however the quartiles are where the mistakes lie.

1. In order to calculate the first quartile, you need to look at where the median of the first half of the values is, ie. 50, 60, 100, 130

The median will be the value between (or the average of) 60 and 100:

(60 + 100)/2 = 80

Thus, the first quartile is 80.

2. In order to calculate the third quartile, we must find the median of the second half of the data set, ie. 140, 150, 180, 200

The median will be the value between (or the average of) 150 and 180:

(150 + 180)/2 = 165

Thus the third quartile is 165.

I find it's always a good idea to just draw this out and label the different values on paper to make it a bit easier.

The minimum, first quartile, median, third quartile, and maximum of the data set are:

Minimum = 50

First quartile = 115

Median = 145

Third quartile = 190

Maximum = 200

It is the middle value of the given set of numbers after arranging the given set of numbers in order.

We have,

To find the minimum, first quartile, median, third quartile, and maximum of the given data set, we need to arrange the data in order from smallest to largest:

50, 60, 100, 130, 140, 150, 180, 200

The minimum is the smallest number in the set, which is 50.

To find the first quartile, we need to find the median of the lower half of the data set.

Since there are 8 numbers in the set, the median is the average of the 4th and 5th numbers in the set:

First quartile = (100 + 130)/2 = 115

The median is the middle number in the set.

Since there are 8 numbers in the set, the median is the average of the 4th and 5th numbers in the set:

Median = (140 + 150)/2 = 145

To find the third quartile, we need to find the median of the upper half of the data set.

Since there are 8 numbers in the set, the median is the average of the 6th and 7th numbers in the set:

Third quartile = (180 + 200)/2 = 190

The maximum is the largest number in the set, which is 200.

Therefore,

The minimum, first quartile, median, third quartile, and the maximum of the data set are:

Minimum = 50
