5 What is the range of
y = -x?- 2x + 3?


A X54
B X > -4
Cy 54
Dy >-4

Answer:

-1 = x              1 = x  

Step-by-step explanation:

We want to factor this first

-4x^2 = -4

x^2=1

sqrt x^2 = sqrt 1

x = ± 1

x=-1        x=1

Answer:

La segunda montaña más alta del mundo tiene 8611 metros.

Step-by-step explanation:

La montaña más alta del mundo es Everest cuya altura es de 8.848m.

La altura de la segunda montaña más alta es de 2hm 3dam y 7m menos. Para calcular la altura que tiene la segunda montaña más alta del mundo, debes realizar primero un cambio de unidades sabiendo que

Entonces podes aplicar las siguientes reglas de tres simple:

Si 1 hm equivale a 100 m, 2 hm equivale a ¿Cuántos metros?

[tex]metros=\frac{2 hm*100 m}{1 hm}[/tex]

metros= 200

Si 1 dam equivale a 10 m, 3 dam equivale a ¿Cuántos metros?

[tex]metros=\frac{3 dam*10 m}{1 dam}[/tex]

metros=  30

Entonces, la altura de la segunda montaña más alta es de 200 m+30 m+ 7 m menos que el Everest. Esto es, 237 metros menos que la montaña más alta del mundo. Entonces:

8848 metros - 237 metros= 8611 metros

La segunda montaña más alta del mundo tiene 8611 metros.

Answer:

Speed in miles per hour = 45 miles per hour

Step-by-step explanation:

Given:

Distance cover by Mrs Perez = 33.75 miles

Time taken by Mrs Perez = 3/4 hours = 0.75 hour

Find:

Speed in miles per hour

Computation:

Speed = Distance cover / Time taken

Speed in miles per hour = Distance cover by Mrs Perez / Time taken by Mrs Perez

Speed in miles per hour = 33.75 / 0.75

Speed in miles per hour = 45 miles per hour

Answer:  

(-1/2,1/2)

Step-by-step explanation:

Normally for sinx amplitude is 2 (1 +1). In the case when it is half sine amplitude is halved, therefore 0.5 +0.5 = 1 Paramers alpha = 2x does not matter because it only stretches the graph horizontally.

Actually Welcome to the concept of Isosceles triangles.

They have two sides equal to each other, so we get as,

==> 3x + 3 = 2x + 8

==> 3x - 2x = 8-3

==> x = 5

hence the length of AC = 5 units.

Answer:

AC = 5

Step-by-step explanation:

here's your solution

=> This is a isosceles triangle

=> both sides are equal.

=> AB = CB

=> 3x + 3 = 2x + 8

=> 3x - 2x = 8 - 3

=> x = 5

so, AC = 5

Answer:

B- 960 square meters

Step-by-step explanation:

Answer:

565.49 or if rounded to the nearest tenth, 565.5

Explanation:

The formula for finding the volume of a cone is V=1/3Bh

B = pi times the radius squared

h = height

Substitute 6 for r and 15 for h.

V= 1/3·[tex]\pi[/tex]·([tex]6^{2}[/tex])·15

Multiply.

V= 565.49 or 565.5 rounded to the nearest tenth.
