I used a calculator, pls let me know if im incorrect

Hey there!

2(p + 1) + 8(p - 1) = 5p

2(p) + 2(1) + 8(p) + 8(-1) = 5p

2p + 2 + 8p - 8 = 5p

10p - 6 = 5p

SUBTRACT 5p to BOTH SIDES

10p - 6 - 5p = 5p - 5p

SIMPLIFY IT!

5p - 6 = 0

ADD 6 to BOTH SIDES

5p - 6 + 6 = 0 + 6

CANCEL out: -6 + 6 because it gives you 0

KEEP: 0 + 6 because it helps solve for the p-value

5p = 0 + 6

5p = 6

DIVIDE 5 to BOTH SIDES

5p/5 = 6/5

CANCEL out: 5/5 because it gives you 1

KEEP: 6/5 because gives you the result of the p-value

SIMPLIFY IT!

p = 6/5

Therefore, your answer is: p = 6/5

Good luck on your assignment and enjoy your day!

Answer:

  y = 9x

Step-by-step explanation:

We notice that each y-value is a multiple of 9, and the multiple is x.

  y = 9x

Step-by-step explanation:

The equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface

ii. The miners elevator is deeper than that of the equipment.

The speed of an object is the rate at which the object moves.

i.e speed = \frac{distance}{time}

time

distance

Thus,

Speed of the equipment elevator = 4 feet per second

Speed of the miners elevator = 15 feet per second.

Time of descent of the equipment elevator = 30 + 14

= 44 seconds

So that, the distance of the elevator at this time is;

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 4 x 44

= 176

distance = - 176 feet

The distance of the miners elevator after 14 seconds is:

speed = \frac{distance}{time}

time

distance

⇒ distance = speed x time

= 15 x 14

= 210

distance = - 210 feet

Thus after another 14 seconds, the equipment elevator is at a depth of 176 feet (-176 feet), while the miners elevator is at a depth of 210 feet (-210 feet) below the surface.

Therefore, the miners elevator is deeper than that of the equipment.

Answer:

A = 42.5 yd²

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

Here b = 17 and h = 5 , then

A = [tex]\frac{1}{2}[/tex] × 17 × 5 = [tex]\frac{1}{2}[/tex] × 85 = 42.5 yd²

y2−x2+1=50

Step 1: Add -y^2 to both sides.

−x2+y2+1+−y2=50+−y2

−x2+1=−y2+50

Step 2: Add -1 to both sides.

−x2+1+−1=−y2+50+−1

−x2=−y2+49

Step 3: Divide both sides by -1.

−x2

−1

=

−y2+49

−1

x2=y2−49

Step 4: Take square root.

x=√y2−49 or x=−√y2−49

Answer:

x=√y2−49 or x=−√y2−49

y2+6y+9=x+8

Step 1: Flip the equation.

x+8=y2+6y+9

Step 2: Add -8 to both sides.

x+8+−8=y2+6y+9+−8

x=y2+6y+1

Answer:

x=y2+6y+1

The degrees on a triangle add up to 180.

(x) + (x-7) + (3x+12) = 180 ; Just shwoing what i'm doing.

x + x-7 + 3x + 12 = 180

5x + 5 = 180 ; x + x + 3x = 5x , 12 - 7 = 5

5x = 175 ; Subtract 5 from 180

x = 35 ; 175/5 = 35

P: x - 7 = 35 - 7 = 28

Q: 3 (x) + 12 = 3 (35) + 12 = 105 + 12 = 117

R: x = 35

Answer:

58

Step-by-step explanation:

We are given the arithmetic sequence:-

-12,-7,-2,3,...

First, find the common difference which we can obtain by:-

[tex] \displaystyle \large{d = a_{n + 1} - a_n}[/tex]

Check:-

-7-(-12) = -7+12 = 5

-2+7 = 5

3+2 = 5

Therefore, our common difference is 5.

General Arithmetic Term

[tex] \displaystyle \large{a_n = a_1 + (n - 1)d}[/tex]

Since we want to find the 15th term, substitute a1 = -12, n = 15 and d = 5.

[tex] \displaystyle \large{a_{15}= - 12 + (15 - 1)5} \\ \displaystyle \large{a_{15}= - 12 + (14)5} \\ \displaystyle \large{a_{15}= - 12 + 70} \\ \displaystyle \large{a_{15}= 58} \\ [/tex]

Answer:

domain: (–∞,∞)    or  all real numbers

range: (–∞,∞)       or  all real numbers

Step-by-step explanation:

domain is left to right (x-axis). looking at the graph, as you go from left to right, the x-values are infinitely getting more negative and positive.

range is bottom to top (y-axis). as you go from bottom to top, the y-values are infinitely getting more negative and positive.

Answer:

3 hours and 45 Minutes

Step-by-step explanation:

If you multiply 45 minutes for five days it's equal to 3 hours and 45 minutes.

Angle 8 and Angle 2 are supplementary. So Angle 8 + 70 would equal to 180.

180-70 is 110 hence angle is 110 degrees.

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the slope formula:

Answer:

x = - (15 - 11y)/4

y = x/2

Step by step explanation:Let's first solve for x

=>- 4x + 11y = 15

=>- 4x + 11y - 11y = 15 - 11y

=>- 4x = 15 - 11y

=>(- 4x)/- 4 = 15/- 4 - (11y)/- 4

x = - (15 - 11y)/4

let's solve for y

=>x = 2y

=>2y = x

=>(2y)/2 = x/2

y = x/2

Answer:

The remainder is 40.

Step-by-step explanation:

We're applying synthetic division here.

The coefficients of this function are {1, 6, -3, 0}.  The divisor (x + 5) is represented by the monomial divisor -5.

Setting up synthetic division, we get:

-5    1    6    -3    0

            -5   -5   40

      ---------------------

       1     1    -8    40

The remainder is 40.

Answer:

so it is basically 2 times 27 or 27 plus 27 witch is 54 you will need 12

Step-by-step explanation:

Answer:

72+(7x+24)=180

7x+96=180

7x=84

x=12

Step-by-step explanation:

Answer: x = 12.

Step-by-step explanation:

72 + (7x + 24) = 180   Now we add like terms

96 + 7x = 180             Take away 96 from both sides

7x = 84                       Divide both sides by 7

x = 12                          X equals 12.

Step-by-step explanation:

Ive heard this joke before lol so corny

1. If two parallel lines are cut by a transversal then the pair of consecutive interior angles are supplementary.

2. If two parallel lines are cut by a transversal then pair of alternate interior angles are equal.

3. m∠1 is  106°.

4.  m∠3 is 74°

5.  m∠8 is 114°

6.  m∠6 is  124°

7. m∠7 is  66°

8.  m∠2 is 66°

We know when a transversal intersects two parallel lines at two distinct points,

Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.

1. If two parallel lines are cut by a transversal then the pair of consecutive interior angles are supplementary.

2. If two parallel lines are cut by a transversal then pair of alternate interior angles are equal.

3. m∠2 is 74° then m∠1 is (180 - 74)° = 106°.    (linear pair of angles)

4. m∠2 is 74° then m∠3 is 74°.    (vertically opposite angles)

5. m∠1 is 114° then m∠8 is 114°   (alternate angles)

6. m∠4 is 56° then m∠6 is (180 - 56)° = 124°  (180° - m∠5)

7. m∠1 is 84° then m∠7 is (180° - m∠8) = 180° - 114° = 66°.

8. m∠8 is 114° then m∠2 is m∠7 = 66°

Answer:

3.4156020*10^-1 for scientific notation if you want to keep that ending zero (I'd normally write it 3.415602*10^-1)

Step-by-step explanation:

So the idea of scientific notation (or engineering notation) is to make things smaller and more manageable. The idea is to move the variables so that one is in front of the point.

So if you had something like this:

12342300000000000000

It'd be equal to 1.23423*10^19

Or something like this

0.0000095675

Would be 9.5675*10^-6
