Answer:

1) x=3/2y+1/2

2)x=-1/3y+-5/3

Step-by-step explanation:

1)

Let's solve for x.

2x−3y=1

Step 1: Add 3y to both sides.

102x−3y+3y=1+3y

2x=3y+1

Step 2: Divide both sides by 2.

2x/2

=

3y+1/2

x=3/2y+1/2

Answer:

Step-by-step explanation:

h(x) = 7 - x - 2x^5

h(-1) = 7 + 1 - 2(-1)^5

h(-1) = 7 + 1 + 2

h(-1) = 10

Now differentiate h(x)

h'(x) = -1 - 2*5*x^4

h'(x) = -1 - 10x^4

h'(x) = -1 - 10(x)^4

h'(x) = -1 - 10 (x)^4

h'(-1) = -1 - 10(10000)

h'(-1) = -1 - 100000

h'(-1) = - 99999

[tex]m = \frac{dy}{dx} = \frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute these coordinate values in.

[tex]m = \frac{0 - ( - 3)}{0 - 1} \\ m = \frac{3}{ - 1} \\ m = - 3[/tex]

Hence, the slope is -3.

From the graph, the line passes through the origin point. Therefore, the y-intercept is (0,0).

[tex]y = mx + b \\ \begin{cases} \sf{m = slope} \\ \sf{b = y - intercept} \end{cases}[/tex]

Substitute both m and b in the slope-intercept form.

[tex]y = - 3x + 0 \\ y = - 3x[/tex]

Hence the answer is y = -3x.

Answer:

16

Step-by-step explanation:

since he needs 32 points to get to 75 points,

soo you just dividi the points you need by the points you get by every question since it's 2 for every question you just need half of the question needed to get to 32 points soo divide it by 2 and the answer you get is 16.

Answer:

No they aren't equal........

Answer:

So the first step would be is to multiply the denominators so you would get this:

6/30 + 5/30

Then you would have 11/30 no simplification needed.

Se image below for more info:

Answer:

11/30

Step-by-step explanation:

To add fractions, you need to find the common denominators

the common denominator for 5 and 6 is 30, because 5*6 = 30

1/5 times (6/6) to get a common denominator of 30. Remember, you have to multiply the numerator by 6 too!

1           6          6

_    x    _    =    _

5         6          30

Now, we just have to multiply 1/6 by (5/5) to get a common denominator of thirty.

1           5          5

_    x    _    =    _

6         5          30

5             6         11

_     +      _    =    _

30          30        30

You final answer should be 11/30

Answer:

t^2+4

Step-by-step explanation:

The perimeter of the table can be given by the equation 2l+2w, and we know the length is 2t-3, meaning 2(2t-3)+2w=2t^2+4t+2, as we know 2t^2+4t+2 is the perimeter. Simplifying we get:

4t-6+2w=2t^2+4t+2

4t+2w=2t^2+4t+8

2w=2t^2+8

w=t^2+4

This means that the table's width is t^2+4

Answer:

3/4x+2

Step-by-step explanation:

Step-by-step explanation:

Answer:

E' (-2,5)

F' (-3,1)

G' (-2,-1)

H' (0,3)

Step-by-step explanation:

The rule for 90 degree clockwise rotation is (h,k) -> (k,-h). This means flip the x-value's sign and then switch x and y's position. For example E (-5,-2), first flip x's sign (5,-2) and then switch x and y's places (-2,5).

Answer:

0.46875 ; 1.133 ; $17 ;19.27

Step-by-step explanation:

Number of slots = 32

0, 00, {1,.. 30}

Odd outcomes = {1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29}

1.) probability of winning :

P(winning) = number of odd outcomes / tot possible outcomes

P(winning) = 15 / 32 = 0.46875

2.)

Odds against winning :

Number of losing outcomes / number of winning outcomes

Not odd numbers / odd numbers = 17 /15 = 1.133

C.)

Payoff odd = 1:1

If bet value = $17 ;

Profit made on winning = $17 * 1 = $17

d.)

If Payoff odd = odd against winning = 17 / 15

Profit on $17

17/ 15 * 17

(1.1333333) * 17

= 19.27

Answer + Explanation:

First, find what the sum of the interior angles must be. You can use the formula 180(n - 2) where n is the number of sides to find this.

n = 5, so 180( 5 - 2) = 180 * 3 = 540 degrees.

Then, you can add up all the interior angles of the pentagon and it will add to 540. This means that:

2x + x + 2x + 90 + 90 = 540

5x + 180 = 540

5x = 360

x = 72

Then you can go through and find the measure of each angle:

S = 90 degrees (given)

T = 2x = 2 * 72 = 144 degrees

U = x = 72 degrees

V = 2x = 72 * 2 = 144 degrees

W = 90 degrees (given)

Answer:369

Step-by-step explanation:

Answer: El otro avión recorrió a distancia de 1362.5 km.

Step-by-step explanation:

Vamos a definir:

Norte es el eje y-positivo.

Oriente (o este) es el eje x-positivo.

Y también sabemos que si tenemos los puntos (a, b) y (c, d)

La distancia entre esos puntos es:

Distancia = √( (a - c)^2 + (b - d)^2)

Ahora, uno de los aviones va hacia el norte, entonces si el aeropuerto está en la posición (0, 0), después de un rato viajando hacia el norte su nueva posición va a ser (0, A)

Mientras que el que va al oeste va a tener una nueva posición (B, 0)

La distancia entre ellos es:

Distancia = √( (B - 0)^2 + (0 - A)^2) = √( B^2 + A^2)

Sabemos que cuando la distancia entre ellos es 1580 km, uno de ellos ha recorrido 800km, asumamos que A = 800km.

Entonces tenemos la ecuación:

1580 km = √( B^2 + (800km)^2)

(1580km)^2 = B^2 + (800km)^2

(1580km)^2 - (800km)^2 = B^2

√((1580km)^2 - (800km)^2 ) = B = 1362.5 km

El otro avión recorrió a distancia de 1362.5 km.

Question:

Round 2,641 to the nearest thousand

Solve:

When the number is less than 5, you move down

When the number is greater or equal to 5, you move up

2 is the thousands place

the number before 2 is 6 on the hundreds place

6 is greater than 5, so you move up

Answer:

-8.4 + 6 hope this helped!

Step-by-step explanation:

Answer:

-38

Step-by-step explanation:

-8.x – 3y

x = 4

y = -2

Since we have the value for x and y we can use that and substitute it into the expression

-8(4) - 3 (-2)

-32 - 6

When you add 2 negative numbers (or subtract them) they will give you a bigger number so think of it as adding 2 positive numeber, but then putting a negative sign in the beginning of it.

-32 - 6

-38

The number of high outliers in the data set will be 1.

The interquartile range is a measurement of a data set's "middle fifty." A range is a measurement of where a set's beginning and end are located.

To get the interquartile range, we must know the first and third quartiles. To find those, we need to know the median of the data.

The following histogram summarizes the ages of the 25 employees who work for Elon's company. According to the 1.5 IQR wall for outliers. The number of the high outliers will be 1.

Answer:

609 males

Step-by-step explanation:

A city council organized a marathon race to promote good health.

Let the number of

Females = x

Males = y

There were 3 times as many female participants as male participants in the marathon.

3x = y

If the total number of participants was 812,

x + y = 812..... Equation 1

We substitute 3x for y in Equation 1

x + 3x = 812

4x = 812

x= 812/4

x = 203 females

3x = y

Solving for y

3(203) = 609 males

The number of males participants = 609

the value of 2⁵ is greater than the value of 5² because 2⁵ is equal to 32 then the value of 5² is equal to 25.

Answer:

w = 215 degrees

Step-by-step explanation:

A  circle = 360 degrees total. So, 145 + w should equal 360.

145 + w = 360

145 + w -145 = 360 - 145

w = 215
