In the following equation, when x=0, what is the value of y? 3x + 4y = 12

iren2701 [21]

Answer:

(3)(0)+4y=12

Step 1: Simplify both sides of the equation.

(3)(0)+4y=12

0+4y=12

(4y)+(0)=12(Combine Like Terms)

4y=12

Step 2: Divide both sides by 4.

4y

4

=

12

4

y=3

Which compound sentence has its solution set shown on the graph below

musickatia [10]

A compound inequality is a sentence with two inequality statements joined either by the word “or” or by the word “and.” “And” indicates that both statements of the compound sentence are true at the same time.

“Or” indicates that, as long as either statement is true, the entire compound sentence is true.

Now as shown in the graph, the solution inequality of the graph is :

x > 3 and x < 5 [please note, circles in the graph indicate exclusion, dots indicate inclusion. in the graph given circles are shown, so it depicts exclusion]

Now let's solve each option to find if it fits in with the above inequality

Option 1 : 2x-4 > 6 or 3x < 9

⇒ x > 5 or x < 3

Option 2 : 2x - 4 < 6 and 3x > 9

⇒ x < 5 and x > 3

Option 3 : 3x + 8 > -7 or -4x < 12

⇒ 3x > -15 or x < -3

⇒ x > -5 or x < -3

Option 4 : 3x + 8 < -7 and -4x > 12

⇒ 3x < -15 and x > -3

⇒ x < -5 and x > -3

So the compound sentence in option 2 : 2x - 4 < 6 and 3x > 9

has its solution set on the graph.

Factor each completely. "If non-factorable, write " Non-factorable" n^3-4n^2+6n-24

SIZIF [17.4K]

$n^{3}$ -4 $n^{2}$ +6n-24
factor out $n^{2}$ from the first two values and 6 from the last two values:
$n^{2}$ (n-4)+6(n-4)
( $n^{2}$ +6)(n-4) is your final answer

Which of the following sets of measurements CANNOT represent the three side lengths of a triangle? A 3 cm, 3 cm, 3 cm B 3 cm. 4

umka21 [38]

Answer:

Step-by-step explanation:

As here,

3 cm + 6 cm = 9cm. = 9cm

And as we know,

According to Triangle Inequality Property, 

Measurement of any two sides of a triangle is always greater than the third side. 

But here,

Sum of two sides is same as the third side,

So,

Option D is the required answer.
