y = 100 - 0.08^ x

Step-by-step explanation:

Sorry that took so long......

Messed up on the last part!

Have a great day!!!!!

Answer:

Together they have $79.52

Standard Form: Ax + By = C

---A cannot be negative, nor can it be a decimal or fraction

y - 6 = -1/2(x - 5)

Distribute the -1/2

y - 6 = -1/2x + 5/2

Add -1/2x to both sides

1/2x + y - 6 = 5/2

Add 6 to both sides

1/2x + y = 17/2

Multiply everything by 2 to get rid of the fractions

x + 2y = 17

Si el año es ordinario, entonces Raquel y Beatriz se encontrarán el 8 de febrero, más si el año es bisiesto, entonces se encontrarán el 7 de febrero.

El período de coincidencia es el tiempo que pasa entre dos fechas en las que Raquel y Beatriz coinciden y queda determinado por el mínimo común múltiplo de los tiempos de frecuencia de cada una. En este caso, el período de coincidencia corresponde a 12 días.

Si tenemos que coincidieron el 24 de febrero, debemos considerar dos posibilidades: (i) Año ordinario, (ii) Año bisiesto.

Si el año es ordinario, entonces Raquel y Beatriz se encontrarán el 8 de febrero, más si el año es bisiesto, entonces se encontrarán el 7 de febrero.

Answer:

The answer is 2a^3\sqrt11a

Step-by-step explanation:

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

Answer:

2[tex]2\sqrt{11} a^{3} \sqrt{a}[/tex]

Step-by-step explanation:

Apply Radical rule: ([tex]\sqrt{ab}= \sqrt{a}\sqrt{b}[/tex])

Which gets you:

[tex]\sqrt{44a^{7} }=\sqrt{44}\sqrt{a^{7} }[/tex]

= [tex]\sqrt{44} \sqrt{a^{7} }[/tex]

Simplify and gets you the answer above

3(m+2) = 5m-58

3m+6 = 5m-58

Step-by-step explanation:

Let's start by decoding this :)

First lets do 60% more than 10; 16 (mental math)

Next, lets do 20% less than 16;  x/16 = 80/100 (Equation)

After solving by cross multiplying & then simplifying (make sure both denominators are 100), you should get 12.8 as your final #! Hope this helped.

Answer:

2/5 * 4/5 =  8/25        7/9 * 2/3 = 14/27   4/7 * 2/3 = 8/21  1/6 * 7/8 = 7/48  2/3 *3/9 = 2/9

Step-by-step explanation: Just multiply the top with top and bottom with the bottom    To draw = just use a ruler for the width  we know if you measure the square box say it is already { 20 mm } wide  then you 2 * 4 = 8 is 2/5 of 20 so you shade the 8mm    Then to get the 4 as ultiplier we know 20/5 =4  

an integer is the number that is not a fraction,

a whole number cannot be negative or fractional or decimal

Answer:

y=2x+1, assuming my change in the reported data was correct.

Step-by-step explanation:

The data for x had one more entry than the values for y.  I removed the second "0" so that the x and y points line up, as shown in the attached image.  The data indicate a straight line, with a slope of 2 (y increases by 2 for every x increase of 1).  The y-intercept is 1, as per the first data point (0,1).

it's actually 92.6666666667 but i rounded

Step-by-step explanation:

Given equation is 4/(s-3) + (s/2) = -2

=> [(4×2)+s(s-3)]/2(s-3) = -2

=> (8+s²-3s)/(2s-6) = -2

=> 8+s²-3s = -2(2s-6)

=> 8+s²-3s = -4s+12

=> s²-3s+8+4s-12 = 0

=> s²+s-4 = 0

The standard form is s²+s-4 = 0

(7x - 1) + 79° = 21x + 8

• An exterior angle of a triangle is equal to the sum of its two interior opposite angles.

[tex](7x - 1) +79 = 21x + 8 \\ 7x - 1 + 79 = 21x + 8 \\ 7x + 78 = 21x + 8 \\ 78 - 8 = 21x - 7x \\ 70 = 14x \\ \frac{70}{14} = x \\ 5 = x \\[/tex]
