-x/3 = 27 ???????????????????????????????????????????????????/

6 0

Im assuming that you are wanting to find x. Follow these steps to get the answer

1. You need to write out the equation
2. You need to get to get the 3 away from that side with the X. To do that, you have to do the opposite of division, which is multiply. You will multiply the 3 by 3 which cancels it out.
3. Since you canceled out the 3 on the one side, you have to do it to the other.
4. Multiply 27 by 3. Which gives you 81.
5. You are left with -x=81. You’ve got to get the x all by itself, so you need to get rid of the negative sign. In order to do that, you need to divide the -x by -1. The reason for that is because you’re taking the negative part of x away, which will leave you with x.
6. Since you divided -1 out of -x, you will need to do that to the other side.
7. That leaves you with x = - 81. Which is your answer.

Solve for x and y simultaneously: X-2y=3 4xsquared-5xy+6y=3

Mkey [24]

X - 2y = 3
4x^2 - 5xy + 6y = 3
lets solve for x the first and substitute in the second:
x = 3 + 2y
4(3 + 2y)^2 - 5(3 + 2y)y + 6y = 3
4(9 + 12y + 4y^2) - 15y - 10y^2 = 3
36 + 48y +16y^2 - 15y - 10y^2 = 3
6y^2 + 33y + 33 = 0
we can solve using the general quadratic formula:
y = (-33 +- √(33^2 - 4*6*33))/12
y = (-33 +- √(297))/12
so there are 2 solutions for y:
y1 = (-33 + √(297))/12
y2 = (-33 - √(297))/12
pick one and then substitute the y value in the first equation to find x

Which geometric model using algebra tiles represents the factorization of x2 – 5x 6? An algebra tile configuration. 4 tiles are

son4ous [18]

The statement for geometric model using algebra tiles represents the factorization is the statement number 2.

<h3>What is algebra tile?</h3>

Algebra tiles used to represent the algebraic expression in the table form. The shape of algebra tile is square and rectangle, in which the variables represented.

The given polynomial equation in the problem is,

$x^2 -5x+6$

In the above polynomial, the highest power of variable is 2. Thus, it is a quadratic equation.The image of the algebra tile for the given polynomial attached below.

The statement which satisfy the polynomial and its algebra tile is,

An algebra tile configuration.

3 tiles are in the Factor 1 spot: 1 is labeled x and 2 are labeled negative.
3 tiles are in the Factor 2 spot: 1 is labeled x and 2 are labeled negative.
11 tiles are in the Product spot: 1 is labeled x squared, 4 are labeled negative x, and 6 are labeled.

Thus, the statement for geometric model using algebra tiles represents the factorization is the statement number 2.

Jon is in a raft 100m from the base of a 54m cliff. What is the angle of depression from the he top of the cliff to the raft? Le

kvv77 [185]

Answer:

28.4 degrees

Step-by-step explanation:

In the diagram attached

Height of the cliff, AB=54 m

Distance of the raft to the base of the cliff, AC=100m

We want to determine the angle of depression from the top of the cliff to the raft. This is angle OBA.

$\angle OBA = \angle BAC $ (Alternate Angles)\\Therefore, in the right triangle ABC\\\tan A =\dfrac{BC}{AC}\\ \tan A =\dfrac{54}{100}\\\tan A =0.54\\A=\arctan 0.54\\A=28.4^\circ$ (to the nearest tenth)$

The angle of depression from the top of the cliff to the raft is 28.4 degrees correct to the nearest tenth.
