Answer:

-6 <= x <= 4

Step-by-step explanation:

a) -15<= 2x -3

-15+3 <= 2x

-12/2 <= x

x >= -6

b) 2x - 3 <= 5

2x <= 5 + 3

x <= 8/2

x <= 4

The number of distinct ways in which the digits of the number 7,511,111 can be arranged is of:

42.

The total number of arrangements of n elements is given by the factorial of n, as follows:

A(n) = n!

When a few of the elements repeat, the number of arrangements with repetition is given by the equation presented as follows, also involving factorials.

[tex]A_n^{n_1, n_2, \cdots n_n} = \frac{n!}{n_1!n_2! \cdots n_n!}[/tex]

In which [tex]n_1, n_2, \cdots n_n[/tex] is the number of times that each element repeats.

For the number 7,511,111, we have that:

Hence the number of distinct arrangements of the number 7,511,111 is given as follows:

7!/5! = 7 x 6 = 42 distinct arrangements.

So we know that x = 90º because it is a right angle. And angle B also has to be 47º because it is a reflection of angle C. And all the angles of any triangle are equal to 180º, so if we do 180-(90+47)=43. So now we know that y=43º and x=90º Your welcome, please give me brainlest.

Answer:

y=0.2x+1

Step-by-step explanation:

2=5a+b

1.2=1a+b

0=-5a+b

we get that a=0.2, b=1

The required equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

A linear equation is defined as an equation in which the highest power of the variable is always one.

According to the given graph,

We can see two points are (-5, 0) and (5, 2)

The linear equation will be: y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₁]

Here

x₁ = -5, y₁ = 0

x₂ = 5, y₂ = 2

⇒ y - y₁ = (y₂ - y₁)/(x₂ -x₁ )[x -x₂]

Substitute values in the equation, we get

⇒ y - 0 = (2 - 0)/(8-4)(x-(-5))

⇒ y - 30 = (2)/(-4)(x + 5)

⇒ y - 30 = -1/2(x + 5)

⇒ y = (-1/2)x - 5/2 + 30

⇒ y = -0.5x + 27.5

Thus, the required equation will be y = -0.5x + 27.5 passes through the points  (-5, 0) and (5, 2).

Answer:

$1.69

Step-by-step explanation:

Half a dollar = $0.50

Eight dimes = $0.80

Six nickels = $0.30

Nine pennies = $0.09

Total = $0.50 + $0.80 + $0.30 + $0.09 = $1.69

Answer:

1.69

Step-by-step explanation:

Step-by-step explanation:

the rate of change is the slope of the line y/x. it is always the factor of x in the equation.

it indicates how many units y changes, when x changes a certain amount of units when going from one point to another.

we only need to look at 2 points.

to go from (0, 4) to (4, -3)

x changes by +4 (from 0 to 4),

y changes by -7 (from 4 to -3).

so the rate of change is -7/3

Answer:

the 4th one

Step-by-step explanation:

Answer:

Step-by-step explanation:

Step-by-step explanation:

first find out the area of sector ECF

π(10)² × 40°/360°

=100π×1/9

=100π/9 m²

now find the area of sector DCG

π(2)² × 40°/360°

=4π/9 m²*

so the area of the shaded region would be the big sector minus the small sector

so

100π/9 - 4π/9

=96π/9

=33.5 m² (3sig.fig.)

*Note that 4π/9 DOES NOT equal to 2π/3

4/9 DOES NOT EQUAL TO 2/3

Answer:

Step-by-step explanation:

Answer:

275mm = 27.5cm

1,000L = 1 kL

Hope this helps :)

275mm= 27.5cm and 1000L= 1KL

Step-by-step explanation:

For 257mm to get to 27.5cm, you have to divide the length value by 10 and so it becomes 27.5. Also for 1000L to become to 1KL you have to divide the volume value by 1000.
