Answer: Simplifying

4x = 4x

Add '-4x' to each side of the equation.

4x + -4x = 4x + -4x

Combine like terms: 4x + -4x = 0

0 = 4x + -4x

Combine like terms: 4x + -4x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

Answer:

  28

Step-by-step explanation:

It is often convenient to compute the Least Common Multiple (LCM) as the product of the numbers divided by their greatest common factor. In this case, that would be ...

  LCM = (14 × 4)/2 = 28

___

As a check, you can do it by looking at the prime factors of these numbers. The LCM will be the product of the unique factors to their highest powers.

  14 = 2·7

  4 = 2^2

Unique factors are 2 and 7. The highest power of 2 is 2; the highest power of 7 is 1.

  LCM = 2^2·7 = 28

Start by setting up a factor tree for 4 and 14.

4 factors as 2 ·  2 and 14 factors as 7 · 2.

When finding the least common multiple, we're looking for factors that match up and here we have a pair of 2's that matches up.

So our least common multiple is 2 from the 2's that match up × the the 2 that doesn't match up x the 7 from the 7 that doesn't match up.

So we have 2 × 2 × 7 or 4 × 7 which is 28.

On my whiteboard, I have attached my factor tree.

Answer:

D) [tex]y\:<\:2x+2[/tex], [tex]y\:>\:-x[/tex]

Step-by-step explanation:

The blue boundary line has a y-intercept of 2 and a slope of  2.

It has equation : [tex]y=2x+2[/tex]

Since the boundary line is not solid and the lower half plane of this line is shaded, its inequality is

[tex]y\:<\:2x+2[/tex]

The blue boundary line passes through the origin and has slope [tex]-1[/tex].

Its equation is [tex]y=-x.[/tex]

Since the boundary line is not solid and the right half-plane is shaded, its inequality is [tex]y\:>\:-x[/tex]

The correct choice is D.

The correct choice is D: y < 2x + 2, y > -x.

The blue boundary line is represented by the equation y = 2x + 2.

Since the lower half-plane is shaded, the inequality is y < 2x + 2.

The blue boundary line also passes through the origin and has a slope of -1, which gives it the equation y = -x.

Since the right half-plane is shaded, the inequality is y > -x.

So, the correct choice is D: y < 2x + 2, y > -x.

Answer:

x=6.7

Step-by-step explanation:

What you have to do is you have to eliminate y. So you need to make y cancel each other out.

2x+2y=17. I can multiply 2 to the second equation to cancel the y's out.

8x-2y=50.

10x=67.

x=67/10 or 6.7.

The value of x for the system of equations will be x=6.7.

A set of simultaneous equations is a finite set of equations for which common solutions are sought in mathematics. It is also known as a system of equations or an equation system.

Given that the two equations are 2x + 2y = 17 and 4x - y = 25. The value of x will be calculated by eliminating the variable y from the equation.

Multiply the second equation by 2 and subtract from the first equation,

2x+2y=17.

8x-2y=50.

10x=67.

x= 67/10

x = 6.7.

Therefore, the value of x for the system of equations will be x=6.7.

answer: 11

explanation: just plug in -2 for x. the new problem becomes 5(-2)^2 - 9. Negative two squared is 4. 5 times 4 is 20. 20 minus 9 is 11.

Final answer:

When evaluating the expression 5x^2 - 9 for x = -2, we substitute -2 into the expression and find that the value is 11.

Explanation:

To evaluate the expression 5x2 − 9 when x = −2, we first substitute the value of x into the expression and then perform the calculation:

5(−2)2 − 9
→ 5(4) − 9
→ 20 − 9
→ 11

Therefore, when x = −2, the value of the expression 5x2 − 9 is 11.

Answer:

(2z - 3)(15z - 4)

Step-by-step explanation:

To factor the quadratic

Consider the factors of the product of the coefficient of the z² term and the constant term which sum to give the coefficient of the z- term

product = 30 × 12 = 360 and sum = - 53

The factors are - 45 and - 8

Use these factors to split the z- term

30z² - 45z - 8z + 12 ( factor the first/second and third/fourth terms )

= 15z(2z - 3) - 4(2z - 3) ← factor out (2z - 3)

= (2z - 3)(15z - 4) ← in factored form

Answer:

1) Factor the denominator and the numerator of each fraction.

2) Simplify.

3) Find the Least common denominator (LCD).

4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator (The LCD is the same denominator of the second fraction, so its numerator stays the same).

5) Apply Distributive property on the numerator and on the denominator.

6) Add like terms.

Step-by-step explanation:

The steps required to determine the sum of the two expressions are:

1) Factor the denominator and the numerator of each fraction:

[tex]\frac{3x+6}{x^2-x-6}+\frac{2x}{x^2+x-12}=\frac{3(x+2)}{(x-3)(x+2)}+\frac{2x}{(x-3)(x+4)}[/tex]

2) Simplify (Remember that [tex]\frac{(x+2)}{(x+2)}=1[/tex]):

[tex]\frac{3}{(x-3)}+\frac{2x}{(x-3)(x+4)}[/tex]

3) Find the Least common denominator (LCD). In this case this is:

[tex]LCD=(x-3)(x+4)[/tex]

4) Rewrite the LCD. Divide it by the denominator of the first fraction and multiply the result of the division by its numerator. As the LCD is the same denominator of the second fraction, its numerator stays the same:

[tex]=\frac{3(x+4)+2x}{(x-3)(x+4)}[/tex]

5) Apply Distributive property on the numerator and on the denominator:

[tex]=\frac{3x+12+2x}{x^2+x-12}[/tex]

Step-by-step explanation:

Slope can be translated to "rise over run". You go down 5 spaces and then move over 4 spaces.

6r -4 +8(15-r) + 23

expand brackets

6r -4 +120 -8r + 23

collect like terms

120 + 23 - 4 = 139

6r - 8r = -2r

139 - 2r

139 - 2r = -3r + 137

-137 from both sides

-2r = -3r -2

add 3r

R = -2

sub in both equations and see if you get the same value

-3r + 137

-3 (-2) + 137

6 +137 = 143

139 - 2r

139 - 2(-2)

139 + 4

143

yes they are equal

Final answer:

After simplifying the given expression by combining like terms and using the distributive property, we find that the simplified form is indeed -3r + 137, which means it is equivalent to the original expression.

Explanation:

To determine if the expression -3r + 137 is equivalent to the given expression 6r – r + 8(15 – r) + 23 – 6, we need to simplify the given expression.

Let's simplify the given expression step-by-step:

Therefore, the simplified form of the given expression is indeed -3r + 137, which means it is equivalent to the given expression.

Since

[tex]a=2x+2,\\ \\b=x+3,\\ \\z=n,[/tex]

then

[tex]2x+2+x+3>n\Rightarrow n<3x+5,\\ \\2x+2+n>x+3\Rightarrow n>1-x,\\ \\x+3+n>2x+2\Rightarrow n>x-1.[/tex]

Thus,

[tex]x-1<n<3x+5.[/tex]

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side. The correct option is A, 3x + 5 > n > x - 1.

Triangle inequality theorem of a triangle says that the sum of any of the two sides of a triangle is always greater than the third side.

Suppose a, b and c are the three sides of a triangle. Thus according to this theorem,

(a+b) > c

(b+c) > a

(c+a) > b

Given the three sides of the triangle 2x + 2 ft, x + 3 ft, and n ft. Now using the triangle inequality theorem we can write,

2x + 2 + x + 3 > n  → 3x + 5 > n

2x + 2 + n > x + 3 → n > -x + 1

x + 3 + n > 2x + 2 → n > x - 1

Since x can not be a negative term therefore, we can write,

3x + 5 > n > x - 1

Hence, the correct option is A, 3x + 5 > n > x - 1.
