Answer:

(-2, 5/3)

Step-by-step explanation:

Step 1: Write out systems of equations

y = 2/3x + 3

x = -2

Step 2: Substitution

y = 2/3(-2) + 3

y = -4/3 + 3

y = 5/3

Step 3: Write solution

(-2, 5/3)

Answer:

[tex]\boxed{(-2, \frac{5}{3} )}[/tex]

Step-by-step explanation:

y = 2/3x+3

x = -2

Plug x as -2 in the first equation.

y = 2/3(-2) + 3

Solve for y.

y = -4/3 + 3

y = -4/3 + 3/1

y = -4/3 + 9/3

y = 5/3

The value of x is given already as -2.

The value of y is 5/3.

The solution to the system of equations is (-2, 5/3).

Answer: 4cm

Step-by-step explanation:

Ok so no matter the orientation of the carton, it will contain the same volume of milk. We can use the fact it's volume of milk will stay constant to find out it's new depth.

Before being turned over the milk volume is:

5 * 8 * 12 = 480. This is because the volume of a cuboid is length * width * height (depth).

Therefore the volume of the milk once turned over is 480

When on it's side, the volume of the milk equals

8 * 15 (the base) * depth

120 * depth

120 * depth = 480

so the depth = 4cm

Answer:

(0,-6) and (-1,0)

Step-by-step explanation:

First:

Set both sides equal to each other: -6x-6=x^2-5x-6

Next:

factor -6 our from the first side and write -5x as a difference:

-6(x+1)=x^2+x-6x-6

Then:

factor out x and -6 drom the second side:

-6(x+1)=x(x+1)-6(x-+1)

Then:

Factor out (x+1)

-6(x+1)=(x+1)(x-6)

Next Combine to one side and factor:

-(x+1)(6+x-6)=0

Simplify:

(x+1) (x)=0

find the zero:

x+1=0 --> x=-1

x=0 --> x=0

Substitute into the equations to find y:

y=-6(-1)-6

y=-6(0)-6

Solve:

y=0

y=-6

Answer:

(x1,y1)= (-1,0)

(x2,y2)= (0,-6)

[tex]1\frac{3}{20}[/tex]

Step-by-step explanation:

'23' fits into '20' one time. So, '1' would be the whole number. We would be left over with  '[tex]\frac{3}{20}[/tex]'  as the remainder, so  '[tex]\frac{3}{20}[/tex]' would be the fraction of the mixed number.  

Put them together, and you get: [tex]1\frac{3}{20}[/tex]

The fraction is already in it's simplest form.

Answer:  8 days

Step-by-step explanation:

Given, At Sami's Shoe Warehouse, it takes 4 over 5 of a day to complete 1 over 10 of an order of sneakers.

i.e. [tex]\dfrac{4}{5}[/tex] x  (1 day) = [tex]\dfrac{1}{10}[/tex] x (an order of sneakers)

Multiply 10 on both the sides , we get

[tex]\dfrac{4}{5}\times10[/tex] x  (1 day) = [tex]\dfrac{1}{10}\times10[/tex] x (an order of sneakers)

⇒[tex]4\times2[/tex] x  (1 day) = an order of sneakers

⇒[tex]8[/tex] x  (1 day) = an order of sneakers

i.e. Time to complete an order of sneakers = 8 days

Hence, it will take 8 days to complete the entire order of sneakers.

Answer:

500cm or 5 meters

Step-by-step explanation:

The ratio of drawing and field is 1:90.

So we have to make 450 m into cm.

450 -> is 45,000

Now we can make 2 fractions,

[tex]\frac{1}{90}=\frac{x}{45000}[/tex]

Cross multiply

90*x = 90x

1*45000 = 45000

90x = 45000

Divide 90 to both sides

x = 500cm

Thus,

the drawing's field is 500cm or 5m long.

Answer:

$95.42  more

Step-by-step explanation:

To find out how much money was made with Investment A after 2 years:

First, we are told that 160 dollars is saved per month for 2 years.  There are 24 months in 2 years, so we have to multiply $160 by 24 months.

160 *24=$3840 after 2 years.

Next, we learn thar 2.5% interest rate is added to the total amount saved in those two years.  So, we must turn 2.5% in to a decimal, which is 0.025.

Now, multiply 3840*0.025 to get $96.

We have to add that on the the amount saved, so 3840+96=$3936.

Investment A made $3936 after 2 years.

To find out how much money was made with Investment B.

So, we have to find compound interest.  The formula for compound interest is:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

In this problem: P=3800, r=3% or 0.03, n=1, and t=2.

So, lets write it out: [tex]A=3800(1+\frac{0.03}{1} )^{2*1}[/tex]

That becomes: [tex]A=3800(1.03)^{2}[/tex]

Simplify it even further: [tex]A=3800(1.0609)[/tex]

Multiply the last two numbers to get: [tex]A=4031.42[/tex]

Investment B made $4031.42 after 2 years.

The question asks us to find out how much more money Investment B made than Investment A after 2 years.  It's simple.  Just subtract Investment A's amount from Investment B's amount.

4031.42-3936=95.42

Investment B made $95.42 more than Investment A after 2 years.

Answer:

1) 33.11 m

2) 58.1°

3) 35·√2

4) 491.925 m²

Step-by-step explanation:

Side length of the pyramid = 35 m

The height of the pyramid = 22 m

The slant height = √(Height² + (1/2 Side length)²)

The slant height = √(22² + (1/2×35)² = 28.11 m

1) The slant edge length = √((Slant height)² + (1/2 Side length)²

The slant edge length = √(28.11² + (1/2×35)²) = 33.11 m

2) The base angle = tan⁻¹((Slant height)/(1/2 Side length))

The base angle = tan⁻¹(28.11/(1/2×35)) = 58.1°

3) The distance between the center pf the base and the corner of the pyramid is half the length of the base diagonal

The length of the base diagonal = √((Side length)² + (Side length)²)

The length of the base diagonal = √(35² + 35²) = 35·√2

The distance between the center pf the base and the corner of the pyramid = 35·√2/2 = 24.75 cm

4) The area of the side of the pyramid = 1/2×(Side length)× (slant height)

The area of the side of the pyramid = 1/2*35*28.11 = 491.925 m²

Answer:

1/3

Step-by-step explanation:

Let's say you picked the blue one first. You have a 2/3 chance of doing that, and now you're left with 2. Now, to pick the green one, you have a 1/2 chance. Multiply that and you  see that you have a 1/3 chance of picking it last.

Answer:

1/3.

Step-by-step explanation:

The probability that the red cube WON'T be picked on the first draw is 2/3. This is because there is a 1/3 probability of picking a green cube, added to a 1/3 probability of picking a blue cube.

The probability that the red cube WON'T be picked on the second draw is 1/2.  This is because one cube has already been picked, so there are two remaining. You can only pick one of the two.

(2/3) * (1/2) = (2 * 1) / (3 * 2) = 2 / 6 = 1/3.

Step-by-step explanation:

Queremos encontrar el valor de x que maximiza la expresión dada.

Veremos que el valor de x que maximiza la producción es x = 4.

Tenemos la expresión:

F(x) = -2*x^2 + 16*x + 25

Y queremos maximizarla.

Notar que es una función cuadratica cuyo coeficiente principal es negativo, es decir, el máximo de la función esta en el vertice.

Para una cuadratica generica:

y = a*x^2 + b*x + c

El vertice está en:

x = -b/2a

Entonces en nuestro caso, el vertice va a estar en:

x = -16/(2*-2) = 4

x = 4

Step-by-step explanation:

so x = minus 9

then

7 × (-9) - 2y = 35

-63 - 2y = 35

-2y = 35 plus 63

-2y = 98

- y = 49

y = -49

Answer:

[tex]\boxed{y = -49}[/tex]

Step-by-step explanation:

=> [tex]7x-2y = 35[/tex]

Given that x = -9

=> [tex]7(-9) -2y = 35[/tex]

=> [tex]-63-2y = 35[/tex]

Adding 63 to both sides

=> [tex]-2y = 35+63[/tex]

=> [tex]-2y = 98[/tex]

Dividing both sides by -2

=> [tex]y = -49[/tex]
