Solve 3x+9 so it has no solution.

Mathematics
1 answer:
Serjik [45]3 years ago
5 0

Answer:

x = -3

Step-by-step explanation:

<em>I hope you mean "no solution" as in 'equal to zero' because that's what I'm doing and what makes sense.</em>

<em>Start by setting the equation equal to zero.</em>

3x + 9 = 0

<em>Subtract the </em><em>9</em><em> from both sides to move it to the right side.</em>

3x = -9

<em>Divide the </em><em>3</em><em> from both sides to isolate the </em><em>x.</em>

x = -3

<em>We can check that </em><em>x = -3</em><em> is the correct answer by plugging it in and seeing if it equals </em><em>zero</em><em>.</em>

3(-3) + 9

-9 + 9

Find the approximate perimeter of ABC plotted below.
maksim [4K]

Answer:

B. 21.2

Step-by-step explanation:

Perimeter of ∆ABC = AB + BC + AC

A(-4, 1)

B(-2, 3)

C(3, -4)

✔️Distance between A(-4, 1) and B(-2, 3):

AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

AB = \sqrt{(-2 - (-4))^2 + (3 - 1)^2} = \sqrt{(2)^2 + (2)^2)}

AB = \sqrt{4 + 4}

AB = \sqrt{16}

AB = 4 units

✔️Distance between B(-2, 3) and C(3, -4):

BC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

BC = \sqrt{(3 - (-2))^2 + (-4 - 3)^2} = \sqrt{(5)^2 + (-7)^2)}

BC = \sqrt{25 + 49}

BC = \sqrt{74}

BC = 8.6 units (nearest tenth)

✔️Distance between A(-4, 1) and C(3, -4):

AC = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

AC = \sqrt{(3 - (-4))^2 + (-4 - 1)^2} = \sqrt{(7)^2 + (-5)^2)}

AC = \sqrt{47 + 25}

AC = \sqrt{74}

AC = 8.6 units (nearest tenth)

Perimeter of ∆ABC = 4 + 8.6 + 8.6 = 21.2 units

What is the pobability that a number cube with six
Snowcat [4.5K]

Answer: \dfrac{1}{6}

Step-by-step explanation:

We know that the total number of outcomes for fair dice {1,2,3,4,5,6} = 6

Given : Favorable outcome = 5

i.e. Number of favorable outcomes =1

We know that the formula to find the probability for each event is given by :-

\dfrac{\text{Number of favorable outcomes}}{\text{Total outcomes}}

Then, the probability that the six  faces cube will land with the number 5 face up will be :_

\dfrac{1}{6}

Hence, the required probability = \dfrac{1}{6}
