Find The Value Of Xx=

Answers

Answer 1

Answer:

The value of x is 3

Step-by-step explanation:

Here, we want to find the value of x

to do this, we apply the principle of similar triangles

That would work as follows;

4/x + 5 = 7/(2x + x + 5)

4/x + 5 = 7/3x + 5

4(3x + 5) = 7(x + 5)

12x + 20 = 7x + 35

12x - 7x = 35-20

5x = 15

x = 15/5

x = 3

Given the function f(x) = 1/2x - 3, evaluate f(10).

Answers

Answer:

f(10)=2

Step-by-step explanation:

f(10) basically means you substitute 10 for x. SO you have f(10)= 1/2(10)-3. 1/2 times 10 equals 5 and 5 -3 is 2 so f(10)=2

The 10 in f(10) means that you plug in 10 for x. f(10) = 2. Here’s my work:

f(x) = 1/2 (10) - 3
f(x) = 5-3
f(x) = 2

Answer:

Please check the explanation.

Step-by-step explanation:

Given the table

Minutes       6         15        27

Pages          20       50       90

Given two points to find the slope

(6, 20)(15, 50)

Finding the slope between (6, 20) and (15, 50)

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [50 - 20] / [15 - 6]

                = 30 / 9

                = 10/3

Thus, the slope = m = 10/3

Using the point-slope form of the linear line function

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line and (x₁, y₁) is the point

substituting the values m = 10/3 and the point (6, 20)

[tex]y-20=\frac{10}{3}\left(x-6\right)[/tex]

Add 20 to both sides

[tex]y-20+20=\frac{10}{3}\left(x-6\right)+20[/tex]

[tex]y=\frac{10}{3}x-20+20[/tex]

[tex]y=\frac{10}{3}x[/tex]

Therefore, the rule relating the minutes, x, to the number of pages, y.

[tex]y=\frac{10}{3}x[/tex]

Determining the number of pages when the minutes equal 72

We already got the equation or rule relating the minutes, x, to the number of pages, y.

[tex]y=\frac{10}{3}x[/tex]

substitute x = 72

[tex]y=\frac{10}{3}\left(72\right)[/tex]

[tex]y=\frac{720}{3}[/tex]

[tex]y=240[/tex]

Therefore, the total pages are 240 when the minutes equal 72

Solution:

The equation of a straight line is in the form y = mx + b, where m is the slope of the graph and b is the y intercept (value of y when x = 0). To graph the line, online geogebra graphing calculator was used for plotting the two graphs by writing the equation of the graphs.

After plotting the two graphs, the intersection of the two lines should be traced to get the x coordinate and y coordinate of the point. This point is the solution of the two graph equations, hence:

Answers

Answer:

270%

Step-by-step explanation:

Hey there!

Step by step explanation:

2.7 is break apart to 200% and 70%. In decimal form, the 7 is 70. 1.0 is also known as 100. This means that 200 would be 200% since 1.00 is equal to 100 and 100 is equal or known as 100%. Now we can add 200% and 70% which would be 270%.

This means that 2.7 in a percent form is 270%.

Computers store information in units called bits and bytes. There are 8 bits in one byte of data. Select the number of bits in one byte as a power with a base of 2.

Answers

Answer:

2^3

Step-by-step explanation:

Given that:

8 bits = 1 byte

To express 1 byte in bits in power notation with a base of 2 ;

1 byte = 8 bits

8bits = 2^x

8 bits = 2 * 2 * 2

8bits = 2^3

Hence,

1 byte = 2^3 bits
