The original price was $20, the sales price is $15. Is this an increase or decrease? What was the percent change?

8a+8+5a−6

=8a+8+5a+−6

=8a+8+5a+−6

=(8a+5a)+(8+−6)

=13a+2

=> (8a + 8) + (5a – 6)

=> (8a + 5a) + (8 – 6) [Combine like terms]

=> (13a + 2)

Answer:

A. the slope is -2

    the y-intercept is (0,1)

Step-by-step explanation:

If y=mx+b, m is the slope and b is the y-intercept.

If we replace the variables with y=-2x+1, we can see -2 is the slope and the y-intercept is (0,1).

Answer:

  c = 17.8, A = 25.7°, B = 64.3°

Step-by-step explanation:

Side c can be found from the Pythagorean theorem:

  c = √(a² +b²)

  c = √(7.7² +16²) = √315.29

  c ≈ 17.8 . . . feet

__

The tangent relation is ...

  Tan = Opposite/Adjacent

  tan(A) = a/b = 7.7/16

  A = arctan(7.7/16)

  A ≈ 25.7°

  B = 90° -25.7°

  B = 64.3°

Answer: 1.1818^37 kg

Step-by-step explanation:

Given that:

Orbit speed = 1300 km/s

Radius (r) = 18 light days

Mass of object the star is orbiting :

Using the relation :

M = rv² / G

Where ; r = Radius in m ; v = velocity in m/s

G = 6.67 * 10^-11 = gravitational constant

18 light days in meters = 4.662 * 10^14 m

v = 1300km/s to m/s

v = (1300 * 1000)m /s = 1300000 m/s = 1.3 * 10^6 m/s

Hence ;

M = (4.662 * 10^14 * (1.3 * 10^6)^2 / (2/3) * 10^-10

M = (4.662 * 10^14) * (1.69 * 10^12) / (2/3) *10^-10

M = (7.87878 * 10^26) / 6.67 * 10^-11

= 1.1818^37 kg

total yards lost = 18

no. of matches = 3

given,

they lost the same number of yards on each play

yards lost on each match = 18/3 = 6

yards lost on second match = 6

Step-by-step explanatio

A.6 yards

Answer:

Y=1x-7

Step-by-step explanation:

First use two points to find the slope. I used the first 2. The formula is (y1-y2)/(x1-x2). So (6-8)/(1-3)= -2/-2 = 1. Then you plug in a point and the slope for the equation y1-y2=m(x1-x2). I am using the first point and m is the slope which is 1. Y-6 = 1(x-1)

y-6 = 1x -1 then get y by itself

y=1x-7

Step-by-step explanation:

Answer: B

Step-by-step explanation:

A = 3.8

B = 3.9

C = 4.0

D = 4.2

You take 4.5 - 3,6 = 0.9, so each big line should be .3.

Answer:

Answer:

a. Profit from each book = $15

b. No, Travis was wrong.

c. Travis isn't correct because Mr. Roberts made $15 from the sales of each book.

Step-by-step explanation:

Given the following data;

Number of books bought = 500

Selling price = $35

Robert savings (cost price) = $9,512 + $488

Robert savings (cost price) = $10,000

Purchasing price = $10,000/500 = $20

Revenues from book sold = 500 * 35 = $17,500

Total profit = Revenues - Cost price

Total profit = $17,500 - $10,000

Total profit = $7,500

To find the amount earned from each book;

[tex] Profit \; from \; each \; book = \frac {Total \;profit}{Numbers \; of \; book} [/tex]

Substituting into the equation, we have;

[tex] Profit \; from \; each \; book = \frac {7500}{500} [/tex]

Profit from each book = $15

Therefore, Mr. Roberts earned $15 from selling each book.

Check:

Selling price = purchasing price + profit = $20 + $15 = $35

Answer:

  2876 books

Step-by-step explanation:

If we let y1 and y2 represent the costs from method 1 and method 2, then we have, for x books published, ...

  y1 = 12841 +24.25x

  y2 = 48072 +12x

These costs will be equal when ...

  y1 = y2

  12841 +24.25x = 48072 +12x

  12.25x = 35231 . . . . . . . . . . . . . subtract 12841+12x

  x = 2876 . . . . . . . . . . divide by 12.25

The costs will be the same for production of 2876 books.

Answer: 35

the age of Roberto is x (x > 3)(x ∈ N)

because Roberto is 3 years older than Carolyn => the age of Carolyn is x - 3

in 7 years, the age of Roberto is x + 7; the age of Carolyn is x - 3 + 7 = x + 4

because  In 7 years the sum of their ages will be 81 =>

x + 7 + x + 4 = 81

⇔ 2x + 11 = 81

⇔ 2x = 70

⇔ x = 70/2 = 35

=>  the age of Roberto is 35

Answer:

Steno lo sebroo disculpa pero lo hice por los puntos gracias

Answer:

Why?:

The interest formula is A = P(1+r/m)^mt

A is the Amount, P is principal (initial investment), R is rate, M is times per year (not used) and T is time.

So if we want 1000 = 800(1+r)^4, we need to find R. In this case, R is about 5 percent.  (I'm not super confident, so see if you have other answers)
