Answer 1

Answer:

Step-by-step explanation:

Let the number be x,

2(4+x)= 4x-6

8+2x= 4x-6

Collect like terms

8+6. = 4x-2x

14 = 2x

x = 14/2

The math SAT score of a high school student graduate can be approximated by S(x)=573-133(0.987), where x is the household income of the student in thousands of dollars per year. What is the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year, in points per thousand dollars? Round answers to 3-decimal places and do not include units with your answer.

Answers

Answer: 0.907

Step-by-step explanation:

The average rate of change in a function from x= a to x = b is given by :-

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

Given: [tex]S(x)=573-133(0.987)^x[/tex]

Then, the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per year will be :

[tex]\dfrac{S(60)-S(40)}{60-40}=\dfrac{573-133(0.987)^{60}-573-133(0.987)^{40}}{20}\\\\=\dfrac{512.34-494.20}{20}\\\\=\dfrac{18.14}{20}\\\\=0.907[/tex]

Hence,  the average rate of change of the SAT score for students with household incomes ranging from $40,000 to $60,000 per yearr= 0.907

3x + 2(4x - 4) = 3
Anyone know the answer?

Answers

Answer:

x=1

Step-by-step explanation:

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

3x+8x-8 = 3

11x-8 = 3

11x = 11

x = 11/11 = 1

The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

The given expression is,

⇒ 3x + 2 (4x- 4) = 3

We can simplify by apply distributive property and combine like term,

⇒ 3x + 2 (4x- 4) = 3

Apply distributive property,

⇒ 3x + 8x - 8 = 3

Combine like term,

⇒ 11x - 8 = 3

Add 8 both side,

⇒ 11x = 3 + 8

⇒ 11x = 11

Divide by 11,

⇒ x = 11 / 11

⇒ x = 1

Therefore, The solution for x in the expression 3x + 2 (4x- 4) = 3 is,

⇒ x = 1

If twelve inches correspond to 30.48 centimeters, how many centimeters are there in thirty inches?

Answers

Answer:

Pythagoras's theorem is used to calculate the sides of a right angle triangle. The formula is represented as follows

c² = a² + b²

where

c = hypotenuse

a and b are either adjacent or opposite sides of the triangle.

6x²-12x-25=-7

axis of symmetry

Answers

Axis of symmetry: x=1
Vertex: (1, -24)

Explanation:

6x²-12x-25=-7

6x²-12x-18=0

a=6, b=-12, c=-18

Formula of axis of symmetry: x=-b/2a

x=-b/2a

x= -(-12)/2(6)

x= 12/12

x= 1

Vertex: (1,?)

Sub x= 1 into the equation,
6(1)² - 12(1) - 18 = y

6 - 12 - 18 = y

y = -24



Answer:

Step-by-step explanation:

                                                                                                           -b

The axis of symmetry can be calculated using this formula:  x = ------

                                                                                                           2a

                                         -(-12)

which in this case is  x = ---------- = 1.  The axis of symmetry is the vertical

                                         2(6)             line x = +1

Thus, x = 1 is the x-coordinate of the vertex.  Normally we'd find the y-coordinate by evaluating the function at x = 1.  Unfortunately your

6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.

Example:  Suppose we have  6x²-12x-25 = f(x) and we evaluate this function at x = 1:  f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)

leads to the vertex (1, -31).

x = 6.6, y = -6.8

Step-by-step explanation:

Subtract  3 x  from both sides of the equation.

y = 13 - 3x

4x + 3y = 6

Replace all occurrences of  y  with  13  −  3 x  in each equation.

-5x + 39 = 6

y = 13 - 3x

Solve for  x  in the first equation.

x = [tex]\frac{33}{5}[/tex] or 6.6

Replace all occurrences of  x  with 6.6  in each equation.

y = [tex]-\frac{34}{5}[/tex] or - 6.8

The time, t, for am ice cube to melt. is inversely proportional to the temperature, T, of the water the ice cube is placed. If it takes an ice cube 2 minutes to melt in 75f water, how long will it take an ice cube of the same size to melt in 80f water?

Answers

Answer:

15/8 minutes

Step-by-step explanation:

The inverse relationship implies the following equation.

[tex]t=\frac{k}{T}[/tex]

where k is a constant.

You are given a t and T that go together, so

[tex]2=\frac{k}{75}[/tex]

This implies that k=150.  Now you know that the relationship is

[tex]t=\frac{150}{T}[/tex]

Now substitute 80 for T to get the answer.

[tex]t=\frac{150}{80}=\frac{15}{8}[/tex][tex]t=\frac{150}{80}=\frac{15}{8}[/tex]

minutes.

It takes an ice cube of the same size to melt in 80f water 15/8 minutes.

We have given,
