what is the value of x in the eqation 3 [2x+5]=3x+4x

Answers

Answer:

x = 15

Step-by-step explanation:

3 ( 2x + 5 ) = 3x + 4x

Distribute;

3 ( 2x + 5 ) = 3x + 4x

6x + 15 = 3x + 4 x

Combine like terms;

6x + 15 = 3x + 4x

6x + 15 = 7x

The graph of function g is a parabola with the vertex located at (5,9). The parabola also passes through the point (3, 1). Which of the following is an
equation in vertex form for this function?

Answers

I just did this the answer is C. g(x) = –2(x – 5)2 + 9

The required function is [tex]g(x)=-2(x-5)^2+9[/tex].

Important information:

Vertex of parabola is at (5,9).Parabola passes through the point (3,1).

We need to find the equation in vertex form for the function g.

Parabola:

The vertex form of a parabola is:

[tex]g(x)=a(x-h)^2+k[/tex]         ...(i)

Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is the vertex.

Substitute [tex]h=5,k=9[/tex] in (i).

[tex]g(x)=a(x-5)^2+9[/tex]          ...(ii)

Parabola passes through the point (3,1). So, substitute [tex]x=3,g(x)=1[/tex] in (ii).

[tex]1=a(3-5)^2+9[/tex]

[tex]1-9=a(-2)^2[/tex]

[tex]-8=4a[/tex]

[tex]-2=a[/tex]

Substitute [tex]a=-2[/tex] in (ii).

[tex]g(x)=-2(x-5)^2+9[/tex]

Thus, the required function is [tex]g(x)=-2(x-5)^2+9[/tex].

Which relation diagram represents a function?

Answers

Answer:

It is going to be the first one on the top left.

Step-by-step explanation:

the rule for something to be a function is every input must have exactly one output. now that does not mean that two different inputs cannot have the same output. but on a vertical line test every other one would be wrong.

A relation will be a function if for every single input there is only one output thus option (A) is correct.

What is a function?

A certain kind of relationship called a function binds inputs to essentially one output.

A function can be regarded as a computer, which is helpful.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

As per the given diagrams,

A relation will be a function if for every single input there is only one output.

In the second diagram for input = 5 the output is 2 and -3 so it will not a function. Similarly third and fourth will also not function.

In the first diagram for  every single input there is only one output.

Hence "A relation will be a function if for every single input there is only one output".

1 1/6 as an improper fraction

Answers

Answer:

The mixed number 1 1/6 converted into an improper fraction is 7/6.

Step-by-step explanation:

The improper fraction representation after converting of 1 1/6 is 7/6 where numerator is 7 and denominator is 6

To convert a mixed number to an improper fraction, we follow these steps:

Multiply the whole number by the denominator of the fraction.

In this case,  multiply 1 (the whole number) by 6 (the denominator), which gives  6.

Add the numerator to the result obtained in step 1.

The numerator in this case is 1. Adding 1 to 6 gives 7.

Place the result from step 2 as the numerator of the fraction, and keep the denominator the same.

The denominator remains 6.

Therefore, the improper fraction representation of 1 1/6 is 7/6.

Answer:

  B. The graph of h(x) opens downward.

  D. The graph of h(x) is wider.

Step-by-step explanation:

The negative leading coefficient causes the graph to be reflected across the x-axis, making it open downward.

The leading coefficient magnitude less than 1 compresses the graph vertically, giving it a wider appearance.

Answers

Answer:

Fifteen minutes and twenty-four seconds.

Step-by-step explanation:

In four minutes, Estabon's drink cooled down 20 degrees (201 - 181 = 20). This means that the drink cooled down five degrees a minute. The drink must cool down 77 more degrees, (181 - 104 = 77). 77 divided by 5 is 15.4. 15.4 translated to seconds is 15 minutes and 24 seconds.

The probability that boys passed in Statistics is 0.4 and the probability that girls passed in Statistics is 0.25. One student is selected at random. What is the probability that the selected student is passed in statistics?​

Answers

Step-by-step explanation:

If a boy student was picked, the probability that they passed is 0.25 * 0.4 = 0.1.

If a girl student was picked, the probability that they passed is 0.75 * 0.25 = 0.1875.

Total probability = (0.1 + 0.1875) * 100% = 28.75%.

Determine whether the functions f(x) = -7/5x +4/5 and g(x) = x – 4 intersect at x = 2.

A.No, because f (2) #g(2) when r =
B. No, because f (0) = 9(2) when I = 2.
C. Yes, because f(x) + 9(2) when r = 2.
D. Yes, because f(x) = 9(2) when I = 2.​

Answers

Answer:

D. Yes, because f(x) = g(x) when x = 2.​

Step-by-step explanation:

Given the functions f(x) = -7/5x +4/5 and g(x) = x – 4, for the functions to intersect, f(x) must be equal to g(x) i.e f(x) = g(x) at x = 2

-7/5x +4/5= x- 4

If x = 2

f(2) = -7/5 (2)+ 4/5

f(2) = -14/5 + 4/5

f(2) = -10/5

f(2) = -2

g(x) = x - 4

g(2) = 2-4

g(2) = -2

Since f(2) = g(2), hence the lines intersects at x = 2
