6x +12

Step-by-step explanation:

Answer:

x = 5.6

Step-by-step explanation:

5x:8 = 7:2

First, find the relationship between 2 and 7.

2 x 3.5 = 7

Since the ratios are equal, this means:

8 x 3.5 = 5x

Solve algebraically. First simply 8 x 3.5

5x = 28

Divide both sides by 5

x = 5.6

Answer:

5.48

Step-by-step explanation:

First, we convert all the fractions into improper fractions. 1 3/7 is 10/7, 3 5/9 is 32/9, and 1/2 stays the same. then we find a common denominator, which would be the LCM of 7, 9 and 2, which is 126. Finally, we rewrite the fractions with the common denominator of 56, and we get 180/126, 448/9 and 63/126. adding these together we get 691/126, which is approximately 5.48412698, which we can round to 5.48

Answer:

m=-2

Step-by-step explanation:

Take 2 points (0,0) and (-3,6)

m(slope)= m = rise/run = y2 - y1/ x2 - x1

y2-y1= 6-0=6

x2-x1 = -3-0 = -3

m=6/-3 = -2

y=-2x

Answer:

(-1, 8) (-5, 11)

Step-by-step explanation:

We are subtracting 3 from the x coordinate and adding 5 to the y coordinate

(2,3) becomes (2-3, 3+5) = (-1,8)

(-2,6) becomes (-2-3, 6+5) = (-5,11)

Answer:

x = 4√2

Step-by-step explanation:

Find the value of x. Leave your answer in simplest radical form. The chord measures 14, the diameter measures 18. Hint: use pythagorean theorem

To solve, we will follow the steps below:

using Pythagoras theorem

opposite² +  adjacent² = hypotenuse²

14² + y² = 18²

196 + y² = 324

subtract 196 from both-side of the equation

196 -196 + y² = 324-196

y² =128

Take the square root of both-side

√y² = √128

y =√128

y = √64×2

y =√64×√2

y = 8√2

x = half of y

x = y/2

x = 8√2  ÷  2

x = 4√2

Answer:

B 45 degrees

Step-by-step explanation:

if AB and CA are = the M2 = 90 degrees

in an right triangle ware one angle is 90 degrees and one is 45 degrees the outer one will be 45 degrees  

the total of the angles in a triangle is 180 degrees so 180 - 90 = 90

90 - 45 = 45

so the remaining angle is 45.

Answer:

Second, Hour, and Millisecond

Step-by-step explanation:

An hour is 60 full minutes

A second is 60 milliseconds

1 Hour = 60 min

1 min = 60 seconds

1 sec = 60 milliseconds

1 millsec = 60 microseconds

1 microsec = 60 nanoseconds

1 nanosec = 60 picoseconds

Answer:

4. (12x)(5x) = 60x^2 because x times x is x to the power of 2

5. F are the front not the back meaning (6)(11) which is 66

Answer:in a the triangle is isosceles therefore it bisects triangle equally into two 90°

B they add up to 180°

C Within the individual triangles they add up to 180°

Answer:

The correct option is C.

C) The range represents the number of users each month for 36 months

Step-by-step explanation:

We have been given that:

x-axis ⇒ Number of Months

y-axis ⇒ Number of Users

x-axis values = 0 to 36

y-axis values = 0 to 60

We have a function which is represented by a straight line from (0,0) to (36,54).

We have to find the RANGE of the function.

Range of a function is a complete set of values of dependent variable y, for all possible values of independent variable x

As total number of months = 36

Range is the set of all values of y (Number of Users) for each month for a period of 36 months.

Hence, the correct option is C.

Answer:

B. Phone company B because the sample was not biased.

Step-by-step explanation:

While Phone company A had a higher satisfaction rate, 25 people that conducted this poll were in at least 1 commerical of the phone company's in the past 3 years. This means that their reflection of the company is biased (typically higher) and not completely based off of their performance but instead how cool it was to be in a commerical or how much they were paid. If the poll was a more random sample of just customers, it would be more believable data. On the other hand, while phone company B had a lower satisfaction rate and higher deviation, their statistics are more believable due to the random sampling of customers.

Answer:

Answer: C. 6 1/6

Step-by-step explanation:

yes

The required value of the expression [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Given that,
The expression [tex]\frac{a + 2bc}{3a}[/tex]  is given, The value of the expression at a = 4, b = -5, and c = -7 is to be determined.

Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Here,
The given expression
=  [tex]\frac{a + 2bc}{3a}[/tex]
At  a = 4, b = -5, and c = -7
[tex]= \frac{4 +2 * -4 * -5 }{3 * 4 } \\= 74 / 12\\= 37 / 6[/tex]

Thus, the required value of the expression  [tex]\frac{a + 2bc}{3a}[/tex]  is 74 / 12 or   37 / 6 .

Answer: i thini its 2

Step-by-step explanation:

The function g(x) is:

g(x) = Ix - 5I.

Therefore, the option A in the given question is correct.

When a function is transformed, the graph's curve either "moves to the left, right, up, or down," "expands or compresses," "reflects," or all three.

The function is made possible by the fundamental function f(x) and the constant

g(x) = f(x - k),

horizontally moving, the f(x) k unit coordinates may be drawn.

The shift's direction depends on the value of k. Specifically,

If k > 0, the basis graph shifts right by k units.

If k < 0, the base graph shifts k units to the left.

Given that the parent function is f(x) = IxI.

From the definition,

the transformed function is moved horizontally to 5 units to the right.

So, the function is g(x) = Ix - 5I.

Therefore, g(x) = Ix - 5I.

======> Mathematics <=======

Step-by-step :

the sum of all angles in the triangle is 180°, So =>

180° = 50° + 60° + x

180° = 110° + x

180° - 110° = x

70° = x

[tex]F(2)=C-12[/tex]

Step-by-step explanation:

Given: [tex]F(x)=x^2-8x+C[/tex]

To find: value of [tex]F(2)[/tex]

Solution:

[tex]F(x)=x^2 - 8x + C\\=x^2-2(4)x+C[/tex]

Add and subtract [tex]4^2[/tex] in the left side of the equation

[tex]F(x)=x^2-2(4)x+4^2-4^2+C[/tex]

Use formula: [tex](a-b)^2=a^2-2ab+b^2[/tex]

[tex]F(x)=(x-4)^2-4^2+C\\=(x-4)^2+C-16[/tex]

Put [tex]x=2[/tex]

[tex]F(x)=(x-4)^2+C-16\\F(2)=(2-4)^2+C-16\\=4+C-16\\=C-12[/tex]
