Answer:

see below

Step-by-step explanation:

6|x/3| < 18

Divide by 6

6/6|x/3| < 18/6

|x/3| < 3

Now we get two equations, one positive and one negative, remembering to flip the inequality

x/3 < 3   x/3 > -3

Multiply by 3 to isolate x

x/3 *3 < 3*3  and  x/3*3 > -3*3

x < 9          and      x > -9

Rewriting

-9 < x<9

Check -12

6|-12/3| < 18

6|-4| <18

24<18  False  good

Check 0

0<18  true

Check 12

6|12/3| < 18

6|4| <18

24<18  False  good

Answer: No, it would not be a solution.

Step-by-step explanation:

The solution to a systems of equations is the point where the lines intersect. The lines do not intersect at (4,-2) so it is not a solution. The lines do intersect at (-2,4), so (-2,4) would be the solution to this system.

[tex]b=-2[/tex]

Step-by-step explanation:

[tex]-9+7b=8b-7\\-9+9+7b=8b-7+9 \leftarrow \text {Addition Property of Equality} \\7b+8b=2\\7b-8b+8b-8b=2\leftarrow \text {Subtraction Property of Equality} \\-b=2\\\frac{-b}{-1}=\frac{2}{-1} \leftarrow \text {Division Property of Equality}\\\boxed {b=-2}\\\\\huge\text {The value of 'b' should be -2}[/tex]

Answer:

Step-by-step explanation:

In the image attached you can observe a representation of this situation.

First, we need to transform each mixed number to a fraction.

[tex]25 \frac{7}{10}=\frac{257}{10}=25.70 \ in[/tex]

[tex]50 \frac{1}{4} =\frac{201}{4} =50.25 \ in[/tex]

[tex]134 \frac{1}{5} = \frac{671}{5} =134.20 \ in[/tex]

Now, if the poster is centers, then the distance to the wall on the right and on the left, must be equal. We know that the space on the right is 50.25 inches. Then, we subtract to find the other side

[tex]134.20-50.25-25.70=58.25 \ in[/tex]

So, the space in the left side of the poster is 58.25 inches long.

Therefore, the poster is not centered.

Answer: $44.10

Step-by-step explanation:

We are given our p, r, t in the problem.

p=40 (starting amount)

r=0.05 (5%)

t=2 (years)

With the given information, we can plug this into our equation.

B=p(1+r)^t

B=40(1+0.05)^2

B=44.1

Answer:

18 golf balls in all, 1/18 is the answer

Step-by-step explanation:

Answer:

1. 18

2. {blue, magenta, purple}

3. P(blue) = 1/2

P(magenta) = 7/18

P(purple) = 1/9

Step-by-step explanation:

Total balls:

9 + 7 + 2 = 18

Sample space: all possible outcomes

{blue, magenta, purple}

P(blue) = 9/18 = 1/2

P(magenta) = 7/18

P(purple) = 2/18 = 1/9

Answer: 27

Step-by-step explanation:

The expression given is inside a cube root. This is a simplified version of a fractional exponent, 1/3.

We can take the expression outside of the radical to get this:

3 ^ 9 ^ (1/3)

When an exponent is raised to another exponent, multiply the exponents and keep the base the same:

3 ^ (9 * 1/3)

3 ^ 3

The expression is equal to 27.

Answer: 56.55

Step-by-step explanation: im assuming there was a typo and instead of free its fee so 25%-12% is 13% and 100%-13% is 87% therefore 87%of 65 is equal to 56.55

Conversion:

12 inches = 1 foot

Divide:

48 / 12 = 4

Therefore, Hailey has 4 feet of ribbon.

Best of Luck!

Answer: 4 foot of ribbon

Step-by-step explanation: there is 12 inches in one foot so this means to get the answer you must divide 48 by 12 to get 4 so 4 feet is the answer

Answer: x = - 3.5

Step-by-step explanation:

Rewrite the equation by completing the square.

4x2 + 28x + 49 = 0

Completing the square method :

Divide through by the Coefficient of x^2

x^2 + 7x + (49/4) = 0

a = 1, b = 7, c = 49/4

Move c to the right side of the equation

x^2 + 7x = - 49/4

Complete the square on the left hand side by squaring its half of the x term

(7/2)^2 = (49/4)

Add the output to both sides of the equation

x^2 + 7x + (49/4) = - (49/4) + (49/4)

(x + 7/2)^2 = 0

Square root of both sides

x + 7/2 = 0

x = - 7/2

x = - 3.5

Answer:

x = - 3.5

Step-by-step explanation:

Please consider the complete question.

A student is deriving the quadratic formula. Her first two steps are shown. Step 1: [tex]-c = ax^2 + bx[/tex]

Step 2: [tex]-c = a[x^2+\frac{b}{a}x][/tex]

Which best explains or justifies Step 2?

A. division property of equality

B. factoring the binomial

C. completing the square

D. subtraction property of equality

We can see that in step 2 student has factored the right side of equation.

The student factored our a from the right side of equation. To factor our a from right side, student has divide the bx term by a.

We can multiply and divide by same quantity in an equation.

[tex]-c = ax^2+a\cdot \frac{b}{a}x[/tex]

Now we can factor out a as:

[tex]-c = a(x^2+\frac{b}{a}x)[/tex]

Therefore, the 2nd step is known as factoring of binomial and option B is the correct choice.

Answer:

it b factoring a binomial on

Answer:

Mean = 78.5

Median = 83

Answer:

19

Step-by-step explanation:

In any triangle, the sum of the measures of the angles is 180 degrees.

(5x + 5) + (x + 16) + (2x + 7) = 180

Combine like terms.

8x + 28 = 180

8x = 152

x = 19

Answer:

No she won't

Step-by-step explanation:

200(0.30)=60

60(0.06)=3.6

60+3.6=63.6

75(0.06)=4.5

75+4.5=79.5

79.5+63.6=143.1

200-143.1=56.9

56.9<60

Answer:

I think you mean: x^2 + 3x - 10, then

x^2 + 3x - 10

= x^2 + 5x - 2x - 10

=x(x + 5)  - 2(x + 5)

=(x - 2)(x + 5)
