for the function g (x) shown graphed below, over which of the following intervals is g (x) > 0

Answer:

x is equal to 19/5 which can also be expressed as  [tex]3\frac{4}{5}[/tex], or 3.8

Step-by-step explanation:

[tex]3x - 2/4 - 2x - 5/3 = 1 + x/6\\\\x - x / 6 = 1 + 2/4 + 5/3\\\\5x/6 = 6/6 + 3/6 + 10/6\\\\\frac{5}{6}x = 19/6\\\\x = \frac{19}{6} * \frac{6}{5}\\\\x = \frac{19}{5}[/tex]

Answer:

x = 12

Step-by-step explanation:

Solve:

[tex]\displaystyle \frac{3x-2}{4}-\frac{2x-5}{3}=\frac{1+x}{6}[/tex]

To eliminate denominators, we multiply all terms by the LCM of 4,3, and 6 = 12.

Multiply by 12:

[tex]3(3x-2)-4(2x-5)=2(1+x)[/tex]

Operating:

[tex]9x-6-8x+20=2x+2[/tex]

[tex]9x-8x-2x=6-20+2[/tex]

Simplifying:

-x=-12

x = 12

1. 2x+y=11

7x=14

rewrite them like this

7x=14;2x+y=11

solve for 7x=14

7x=14

x=2

Substitute 2 for x in 2x+y=11

(2)(2)+y=11

y+4=11

y=7

2. −7x=14;9x+8y=6

9x+8y=6

-7x=14

fist solve for x

x=-2

Then substitute in first equation

y=3

3. 6x+4y=6;3x=−15

6x+4y=6

3x=-15

solve for x

x=-5

Then plug in and solve

(6)(−5)+4y=6

4y=36

y=9

4. 7x+4y=24;4x=16

same process solve for x and plug in

x=4 and y=−1

5.  5x+8y=14;4x=24

same process

x=6 and y=−2

6. x-5y=21;-6x=24

same process solve for x and plug it in

x=−4 and y=−5

Answer:

The height of the pile is increasing at a rate of 1.78 ft/min

Step-by-step explanation:

As we can see, we have the rate at which the volume is increasing

Mathematically, the volume of a cone can be calculated by the formula;

1/3 * π * r^2 * h

but here, we are dealing with base diameter which is d

and r is d/2

So we have the formula as;

1/3 * π * (d/2)^2 * h

since h is same as d for this particular cone, we can replace d with h so that we now have;

1/3 * π * h^3/4

= πh^3/12

what we have in the question is dv/dt

what we want to calculate is dh/dt

Mathematically;

dh/dt = dh/dv * dv/dt

dh/dv is 1/dv/dh

dv/dh = πh^2/36 where h = 15

dv/dh = 225 π/36

dh/dv is now;

36/225π

So, finally;

dh/dt = 36/225 π * 35

dh/dt = 1.78 ft/min

Step-by-step explanation:

For childcare facilities for each visit is $9, we would say 9x because we dont know the exact amount of time that she visits the gym with her child. Her monthly gym bill is $32 which would ve added to the amount she would pay for childcare. The sum of it all should be less than or equal to that of $122.

Answer:

A. 9x + 32 ≤ 122

Step-by-step explanation:

$32 is the fixed monthly due

$9 everytime she uses childcare

$122 is the maximum she wants to spend This month.

32 + 9x ≤ 122

Answer:

Step-by-step explanation:

They are similar by the definition of similarity in terms of a dilation.

Two figures must have congruent (equal) comparable angle measures and proportional sides in order to be considered similar. Dilations produce comparable numbers because adding the scale factor produces proportional sides while keeping the angle measurement and form constant.

Answer:

  (4x +5)

Step-by-step explanation:

The square of a binomial is ...

  (a +b)² = a² +2ab +b²

We assume that the given trinomial is a perfect square, so we can find the terms of the squared binomial by looking at the square roots of the first and last terms:

  √(16x²) = 4x

  √25 = 5

So, our first choice of side length for the square is ...

  s = (4x +5) . . . . . side length of the square

__

Using the above identity, we can verify that the square of this gives the right area:

  A = s² = (4x +5)² = (4x)² +2(4x)(5) +5²

  A = 16x² +40x +25 . . . . . . as required

Associative property of addition

Answer:

Step-by-step explanation:

It is H

        Function for the graph of the parabola given in the picture attached will be Option (H). f(x) = x² - 6x

          y = a(x - h)² + k

          Here, (h, k) is the vertex of the parabola

Given in the graph,

Equation of the graph with vertex (3, -9) will be,

y = a(x - 3)² - 9

Since, the parabola passes through (0, 0),

0 = a(0 - 3)² - 9

0 = 9a - 9

a = 1

Substitute the value of 'a' in the equation of the parabola,

y = 1.(x - 3)² - 9

y = x² - 6x + 9 - 9

y = x² - 6x

      Hence, the function representing the graph will be f(x) = x² - 6x

Richard's cumulative GPA = 2.5

Step-by-step explanation:

Richard's cumulative GPA for 3 semesters was 2.0 for 42 credits.

Average = 2

Total credits = 42

Average = sum of terms/total no of terms

2 = sum of terms/42

sum of terms = 84 ....(1)

His fourth semester GPA was 4.0 for 14 course units

Average = 4

Total credits = 14

C. ECA = BDA

Step-by-step explanation:

An angle is said to be produced whenever two or more lines meet at a point. An interior angle is an angle form within two lines meeting at a point. Then, alternate interior angles are internal angles that are equal due to alternate theorem. These angles should have equal measures.

From the given question, the alternate interior angles by the theorem is;

ECA = BDA

By the alternate interior angle theorem, the alternate interior angles are ECA and BDA. This implies that the measure of <ECA should be equal to the measure of <BDA.
