The system of inequalities and a possible solution is by working 2 hours removing wires and 6 hours tutoring.

What is Inequalities?

An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The most frequent application is to size-compare two numbers on a number line.

Here are the variables defined:

x is the quantity of tutoring hours worked.

Y = quantity of h

clearing cables is our job.

Since we know she can only work a maximum of 9 hours per week:

x + y ≤ 9

She also wants to earn at least $130 each week, so:

x*$22 + y*$10 ≥ $130

As a result, we have the inequality system listed below:

x + y ≤ 9

x*$22 + y*$10 ≥ $130

The graph of this system can be shown in the graphic below, where the intersection of the two shaded regions shows where the system's solutions are.

There are some solutions there, including:

y = 0, x = 8

y = 2, x = 6.

Answer:

  (a) in 2001: 150.4 thousand

  (b) in 2018: 467.5 thousand

Step-by-step explanation:

You want the value of the expression modeling the number of students abroad for different values of x. That expression is 123.1(1.069^x).

The value of x is the difference between the year (2001) and the reference year (1998). In the attachment, we let the calculator find that difference. It tells us, for x = 2001 -1998 = 3, the number of students is about ...

  y = 123.1(1.069^3) ≈ 150.4 . . . . thousand

In 2018, the value of x is 2008 -1998 = 10, and the number of students studying abroad is ...

  y = 123.1(1.069^10) ≈ 467.4 . . . . thousand

If the measurement of ∠3 & ∠6 is given,i.e.∠3 = 4x + 7 and ∠6 = 2x + 53 then ∠1 = 120 - 6x.

Given, ∠3 = (4x + 7) and ∠6 = (2x + 53)

Let ∠1 = a,

Now, as we know the angle sum property in triangles,

the sum of all the angles in a triangle is 180°.

So, ∠1 + ∠3 + ∠6  = 180°

a + (4x + 7) + (2x + 53) = 180°

a + 6x + 60 = 180

a = 180 - 60 - 6x

a = 120 - 6x

Hence, ∠1 = 120 - 6x, if the ∠3 = 4x + 7 and ∠6 = 2x + 53

Answer:

m = -3

b = 8

Step-by-step explanation:

y = -3x + 8 is in slope-intercept form, which is:

y = mx + b

so the slope is the m, the number right there beside the x. In your equation its -3. The b is the y-intercept, so its the last number tacked on the end of the equation there on the right. For your question, its the 8.

Slope is -3 and y-intercept is 8.

The acute angles in a right triangle have measures of 30 degrees and 60 degrees if the ratio of these angles is 1:2.

The hypotenuse, along with the two legs, make up a right triangle. The hypotenuse, the longest side of the right triangle and the side opposite the right angle, is where the two legs of a right triangle come together at a 90° angle. There are a few unique varieties of right triangles, including the 45°-45° and the 30°-60° varieties.

The ratio of the angular dimensions of the acute angles of a right triangle is 1:2.

Consider x

Sum of three angles is 180 degrees.

Now,

180=90 + x + 2x

180 - 90=3x

3x = 90

x = 30

here, x and 2x, are two angles  30 and 60 degrees.

Option2 and 4 are the exponential decay from the equation.

Given that,

We have to find which one is exponential decay function.

Exponential decay function is in the form of y=abˣ where a is the initial value and b≠0,  0<b<1. power is x.

Now, Take the 1st option

y=0.25(2)ˣ

Here a is 0.25 and 2 is b

b>1

So, Option 1 is not an exponential decay.

Now, Take the 2nd option

y=2(0.20)ˣ

Here a is 2 and 0.20 is b

b<1

So, Option 2 is an exponential decay.

Now, Take the 3rd option

y=4.2(1.25)ˣ

Here a is 4.2 and 1.25 is b

b>1

So, Option 3 is not an exponential decay.

Now, Take the 4th option

y=0.55(0.91)ˣ

Here a is 0.55 and 0.91 is b

b<1

So, Option 4 is an exponential decay.

The cake slice with 15m due west and 15m due north is closer

Here , the slice of cake is 20m due east and then 10 m due south.

consider it as triangle ABC.

Required Displacement can be calculated by Pythagoras theorem -

AC = √ ( AB )² + ( BC )²

By substitution,

⇒ AC = √ ( 20 )² + ( 10 )²

⇒ AC = √ ( 400 + 100 )

Simplifying this equation, we get

⇒ AC = √500

⇒ AC = 10 √5

⇒ AC = 22.56

Thus , The cake slice is 22.56 m far away.

Here another slice of cake is 15m due west and 15m due north.

consider it as a triangle DEF.

Therefore,

⇒ DF = √ ( DE )² + ( EF )²

By substitution,

⇒ DF =  √ ( 15 )² + ( 15 )²

Simplifying this equation, we get

⇒ DF = √ ( 225 + 225 )

⇒ DF = √ 450

⇒ DF = 15 √2

⇒ DF = 21.21

Thus the cake slice is 21.21 m far away.

Let us assume the number to be x. So, there will be two sides of equation, that is Left Hand Side and Right Hand Side. Writing the equation for each side.

Left Hand Side = 11x - 21

Right Hand Side = 7x - 29

Equating both sides of the equation.

11x - 21 = 7x - 29

Rewriting the equation with identical values on each side

11x - 7x = 21 - 29

Performing subtraction on both sides of the equation

4x = -8

Shifting 4 to Right Hand Side of the equation

x = -8 ÷ 4

Performing division on Right Hand Side of the equation

x = -2

The coordinates of triangle PQR under the translation (x,y) → (x+2,y-4) are P'(-1,-6), Q'(1,0), R'(4,-6).

Translation of coordinates is done by adding the horizontal translation at each vertex of the triangle. It is the process of shifting the location of the figure without changing the size and dimensions of the figure.

The coordinates of the triangle PQR are given as P(-3,-2), Q(-1,4), R(2,-2). The property under translation is given as (x,y) → (x+2,y-4). Now, let us apply this for all vertices.

P(-3,-2) → P'(-3+2,-2-4) → P'(-1,-6)

Q(-1,4) → Q'(-1+2,4-4) → Q'(1,0)

R(2,-2) → R'(2+2,-2-4) → R'(4,-6)
