Answer:

Step-by-step explanation:

The midpoint formula is useful here. For midpoint M, we have ...

  M = (C + D)/2

  2M = C + D

  2(10, 10) = (15, s) +(t, 3)

  (20, 20) = (15+t, s+3)

  t = 20 -15 = 5

  s = 20 -3 = 17

__

Check

  (C +D)/2 = ((15, 17) +(5, 3))/2 = (20, 20)/2 = (10, 10) . . . checks OK

t = 12

Answer:

c. x=1,000

Step-by-step explanation:

log x = 3

Imagine that it's log10 x = 3

So, x =  10^3 (10 to the third power)

x = 10 * 10 * 10

x = 1,000

Answer:

-5

-3 + -5 = -8

Answer:

18.75%

Step-by-step explanation:

Green beans = 160 pounds

Amount sold in 1 hour = 10 pounds

Amount sold in 3 hours = 3x10= 30 pounds

Decrease in 3 hours = 30 pounds

% decrease = (30/160) x 100

=300/16

=75/4

=18.75%

Answer:

At the end of 50 days , Amount of money = $2500x

where x is the value that added every day.

Step-by-step explanation:

Let daily amount added in 1 envelope = $x

As, we have 50 envelope,

so, daily added amount in 50 envelope = $ 50x

⇒ Each day , we add money = $ 50 x

After 50 day, it becomes  $50×50x = $2500x

For example -

If we add $ 1 every day in each envelope

then ,

Total amount added in 50 envelope each day = $50×1 = $ 50

Then,

After 50 days,

Total amount = $ 50×50 = $2500

∴ we get

At the end of 50 day, total amount we have = $2500

Answer:

9x^2-9x-3

Step-by-step explanation:

3x*3x=9x^2

3x*-4=-12x

1*3x=3x

1*-4=-3

9x^2-12x+3x-3

9x^2-9x-3

Answer:

9x^2 - 9x - 4

Step-by-step explanation:

(3x + 1)(3x – 4)

Here you can use the FOIL method (FOIL stands for: First, Outer, Inner and Last)

First you multiply 3x by 3x since these are the First inside both binomials.

3x * 3x = 9x^2

Then you multiply 3x by -4 since these are the Outer inside both binomials.

3x * -4 = -12x

Then you multiply 1 by 3x since these are the Inner inside both binomials.

1 * 3x = 3x

Then you multiply 1 by -4 since these are the Outer inside both binomials.

1 * -4 = -4

And finally add everything together:

9x^2 + (-12x) + 3x + (-4)

Since adding a negative number is the same as subtracting it:

9x^2 - 12x + 3x - 4

We can now simplify this a little by adding all the x's together:

9x^2 - (12x + 3x) - 4 =

9x^2 - 9x - 4

Answer:

5x = 2y

Step-by-step explanation:

Responda:

$ 980

Explicação passo a passo:

Dado que:

Salário mensal = $ 1400

Data de emprego = 10 de janeiro

Usando o sistema de mês de 30 dias:

Taxa diária =. $ 1400/30 = $ 46.66666

Dias não trabalhados = janeiro - 9 de janeiro = 9 dias

Subtraia o salário de 9 dias do total:

Salário total - (9 * taxa diária)

$ 1400 - (9 * $ 46,66666)

$ 1400 - $ 420

= $ 980

Portanto, o saldo do salário é de $ 980

Answer:

(y - 6) = 3/5(x - 5)

Step-by-step explanation:

First, let's look at what point-slope form is: (y - y₁) = m(x - x₁)

Let's plug in the vallues we know.

m is the slope: 3/5

x₁ is 5

y₁ is 6

Therefore:

(y - 6) = 3/5(x - 5)

This is your equation.

Answer:

510/600 of the shirts are not yellow or pink.

Step-by-step explanation:

First we turn 7/200 with a denominator of 600.

7/200 = 21/600

Next we add 69/600 with 21/600.

69/600 + 21/600 = 90/600

Now we subtract 600 by 90.

600 - 90 = 510.

So, the answer is 510/600

Hope this helps! :)

Answer: y = 2x + 4

Step-by-step explanation:

y = mx + b

(1,6) and (2,8)

Finding Slope:

(8 - 6) / (2 - 1)

=> 2/ 1 or 2

y = 2x + b

Finding "B":

y = 2x + b

=> 6 = 2(1) + b

=> 6 = 2 + b

=> b = 4

so y = 2x + 4

4.  5.75%

5. $15,785

6. $20,960

Step-by-step explanation:

I (interest) = p(principal, or money deposited) x r (rate, converted from percentage to decimal) x t (time, in years)

Plugging in info for #4:

241.50 = (1,050) (r) (4)

241.50 = 4200r

divide both sides by 4200

r = 0.0575

multiply by 100 to change from decimal to percentage, = 5.75% is the rate

Plugging in for #5:

(remember to divide percentage by 100 to go from percent to decimal)

I = (410,000)(0.0385)(1)

Interest = $15,785

Number 6 takes two steps. One is the equation we've been doing, the other is to add that interest to the amount deposited in the first place.

I = (8,000)(0.09)(18)

Interest = $12,960

Now add the $12,960 to the $8,000 deposit in the first place, and you have $20,960
