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:

To eliminate the x-terms, multiply the second equation by 2.

To eliminate the y-terms, multiply the second equation by 3.

Step-by-step explanation:

The first step of solving by elimination requires that you eliminate either the x-terms or y-terms by making the two terms have the same coefficient, but opposite signs.  

So, if you wanted to eliminate the x-terms, you could multiply the second equation so that its x term has the same coefficient as the x-term in the first equation, but with opposite signs. The x-term in the first equation is 4x. The x-term in the second equation is -2x. They already have opposite signs, so we just need the -2x to become -4x. -4x divided by -2x is 2, thus you would multiply the second equation by 2.  

If you wanted to eliminate the y-terms, the process is the same. The y-term in the first equation is -9y and the y-term in the second equation is 3y. Again, they already have opposite signs, we just need 3y to become 9y. 9y divided by 3y is 3, thus you would multiply the second equation by 3.

Answer:

to eliminate x, u would multiply second equation by 2

to eliminate y, u would multiply second equation by 3

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:

slope: 1

Step-by-step explanation:

(1, 2) and (3, 4)

To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(4 - 2) / (3 - 1)

Simplify the parentheses.

= (2) / (2)

Simplify the fraction.

2/2

= 1

This is your slope.

Hope this helps!

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.

Answer:

6n - 1.

Step-by-step explanation:

Arithmetic sequence.

a1 = 5, d = 6.

nth term = a1 + d(n - 1)

= 5 + 6(n - 1)

= 5 + 6n - 6

= 6n - 1.

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:

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: 2,641⇒3,000

Step-by-step explanation:

      2                       6                     4                 1

Thousand         Hundred            Ten             one

------------------------------------------------------------------

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

Hope this helps!! :)

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

Hope this helps :)

Answer:

1cm

Step-by-step explanation:

Kindly refer to the attached image for clarity

Given data

Let the big circle have a radius R= 3.5cm

and the small circle have a radius r= 2.5cm

From the image, we can see that the distance between the two centers is the difference of the radii

Distance= R-r

Distance= 3.5-2.5= 1cm

Hence the distance is 1cm

Answer:

3/4x+2

Step-by-step explanation:

We can see the y intercept is 2 so our equation looks like this

y=mx+2

We just need to solve for m

We can take the point

(4,5)

and plug it in

5=4x+2

solve for x

x=3/4
