Answer:

The correct answer is b) 3p = 6

Step-by-step explanation:

First, we need to find p:

3p - 2 = 6p + 4

-2 = 3p + 4

-6 = 3p

-2 = p

Now, we just need to plug p's value into each question:

a) 3p = 6p + 6

3(-2) = 6(-2) + 6

-6 = -12 + 6

-6 = -6

Since -6 = -6, a is not the correct answer.

b) 3p = 6

3(-2) = 6

-6 = 6

Since -6 ≠ 6, b is the correct answer.

c) -6 = 3p

-6 = 3(-2)

-6 = -6

Since -6 = -6, c is not the correct answer.

d) -3p - 2 = 4

-3(-2) - 2 = 4

6 - 2 = 4

4 = 4

Since 4 = 4, d is not the correct answer.

Therefore, b is the correct answer.

PLEASE HELPPPPPP!!!!!!Solve this system of linear equations separate the x-and y-values with a comma

GenaCL600 [577]

Answer:

$x=-6,\\y=6$

Step-by-step explanation:

Rewrite the system of equations as:

$\begin{cases}-13x+2y=90\\-6x+2y=48\end{cases}$

Subtract the second equation from the first to isolate $x$ :

$-13x+2y-(-6x+2y)=42,\\-7x=42, \\\fbox{$x=-6$}$

Plug in $x=-6$ into any of the equations above and solve for $y$ :

$-6(-6)+2y=48,\\2y=12,\\\fbox{$y=6$}$

Verify that the solution pair $(-6, 6)$ works $\checkmark$

Therefore, the solution to this system of equations is:

$x=-6,\\y=6$

SOMEONE PLEASE HELLPPPP

ipn [44]

Answer:

93.39

Step-by-step explanation:

So the sum of exterior angles of the convex octagon is: 360 degrees

This means if we add all the equations that represent each angle, we can set it equal to 360 and solve for x

$(x+14) + (2x-3) + (3x+8) + (3x+16) + (2x-17) + (3x-4) + (3x-12) + (6x)$

Group like terms

$(x+2x+3x+3x+2x+3x+3x+6x) + (14-3+8+16-17-4-12)$

Add like terms

$23x+2$

Now let's set the sum of exterior angles to 360

$23x+2 = 360$

Subtract 2 from both sides

$23x=358$

Divide both sides by 23

$x\approx 15.565$

So by looking at all these, it appears that 6x is the highest value, given that x is positive. The way I estimated, is approximately 15.5, whenever I saw an equation like x+14, I estimated it's about 2x, since 14 is not exactly, but close to 15.5. I did this with each polynomial given. You could also manually check each one

Original equation

6(15.565)

Simplify

$93.39$

Identify the reference angle

ser-zykov [4K]

Answer:

Below in bold.

Step-by-step explanation:

300 degrees - reference angle is |360 - 300 |= 60 degrees

225 = 225 - 180 = 45 degrees

480 = 480 - 360 = 120 so it is 180 - 120 = 60 degrees.

-210 = |-210 + 180| = 30 degrees.
