Answer:

The region to the left of -8 including -8 in the number line

Step-by-step explanation:

Given in an inequality in variable x as

$-0.5x\geq 4$

To solve for x we divide by -0.5

Since we divide by a negative number we find that inequality is reversed.

$x\leq \frac{4}{-0.5} =-8$

So solution is

$x\leq -8$

Hence the solution is the region to the left of -8 in the number line.

There are 36 students on the bus. There are 2 times as many girls than boys on the bus. On your paper, write a system of liner e

Ghella [55]

X = girls
y = boys
z = students in the bus

x + y = z
x + y = 36

total girls = 2 * total boys
x = 2 * y

2y + y = 36
3y = 36
y = 12
x = 2y = 24 (B)

The product of 3 x is less than 9

3x-9 would equal 3(x-3) because you factor the 3 out of the 9.

A bird has a mass of 26 g and perches in the middle of a stretched telephone line. (a) Show that the tension in the line can be

Semmy [17]

Answer:

a) is demonstrated below, b) T=1.462N, c) T=14.6N

Step-by-step explanation:

a) Refer to the attached diagram.

Since the bird is standing in the middle of the line and each half is a straight line, Ta=Tb, so we will call the tension T=Ta=Tb and Tay=Tby

By trigonometry Tay=Ta·Sinθ

Since the system is in equilibrium W=Tay+Tby then:

W=2·Tay=2·Ta·Sinθ=2·T·Sinθ

Since W=mg, being m the mass of the bird and g, gravity:

$mg=2TSin\theta$
