Answer:

{(-5, 7), (-4, -9), (–5, – 4), (2, -6)}

Step-by-step explanation:

In a function, no two points can have the same x-coordinates. In other words, all x-coordinates of the points must be different.

{(5, -6), (-1, - 2), (2, –9), (–8, -2)} : All x-coordinates are different: 5, -1, 2, -8. This is a function.

{(-5, 7), (-4, -9), (–5, – 4), (2, -6)} : Two x-coordinates are the same: -5, -5. This is not a function.

{(-4,2), (-2,8), (-1,6), (5,6)} : All x-coordinates are different: -4, -2, -1, 5. This is a function.

{(2,2), (-4,9), (9, -3), (-3, 2)}: All x-coordinates are different: 2, -4, 9, -3. This is a function.

Step-by-step explanation:

The figure of the triangle is attached and we have the following data:

[tex]A=45\°[/tex]

[tex]s=18[/tex] is the length of arc

[tex]r=14[/tex] is the radius

This problem can be solved by the Law of Sines:

[tex]\frac{sin A}{r}=\frac{sin C}{y}=\frac{sin D}{r+x}[/tex]

In order to find [tex]C[/tex], we will use the formula of the length of arc:

[tex]s=\frac{2 \pi r C}{360\°}[/tex]

Then: [tex]C=\frac{360\° s}{2 \pi r}[/tex]

[tex]C=\frac{360\° (18)}{2 \pi (14)}=73.66\°[/tex]

Returning to the Law of Sines:

[tex]\frac{sin A}{r}=\frac{sin C}{y}[/tex]

Finding [tex]y[/tex]:

[tex]y=\frac{sin C r}{sin A}[/tex]

[tex]y=\frac{sin (73.66\°) 14}{sin (45\°)}[/tex]

Finally:

[tex]y=18.99 \approx 19[/tex]

The length of side y is approximately 19 units.

The problem can be approached using the Law of Sines, which relates the angles and sides of a triangle. Given the data:

Angle A (A) is 45°, the side opposite angle A (s) is 18 units, and the radius of the circumcircle (r) is 14 units.

This problem can be solved by the Law of Sines:

sinA / r = sinC / y= sin D/ r + x

To find the length of side y, we can first calculate the measure of angle C (C) by using the formula for the length of an arc:

s= 2πrC/ 360

Then:

C= 360 s/ 2πr

C= 360 (18) / 2π(14)

C= 73.66

Now, we can use the Law of Sines to find the length of side y. The Law of Sines states:

sinA / r = sinC / c

In this case, we want to find side y, which is opposite angle C:

sinA / r = sinC / y

Solving for y :

y = sinCr/ sinA

y= sin ( 73.66 )14/ sin 45

Finally:

y = 18.99 = 19

So, the length of side y is approximately 19 units.

Jeremy’s net income was $514.8

Step-by-step explanation:

The given is:

We need to find what Jeremy’s net income was

The net income = total income - taxes

∵ Jeremy’s pay is $8.25 per hour

∵ Jeremy worked 78 hours in a month

- Jeremy's income =  the pay for an hour × the worked hours

∴ Jeremy's income = 8.25 × 78

∴ Jeremy's income = $643.5 in a month

∵ There was $128.7 as taxes in his pay statement

∴ The taxes = $128.7

- Substitute the values of his income and the taxes in the

   formula of the net income

∵ The net income = total income - taxes

∴ The net income = 643.5 - 128.7

∴ The net income = $514.8

Jeremy’s net income was $514.8

Answer:

B. x < 5

Step-by-step explanation:

Lets go first with 3x – 8 < 23  then with - 4x + 26 > 6 and after that we put them together. (I will use the < > signs but as I see on the pictures these include the =, being less and greater OR equal).

3x – 8 < 23

Lets sum 8 in both sides:

3x < 23 +8

3x < 31

Now, divide both sides by 3:

3x/3 < 31/3

x < 31/3

Here we found one condition. Lets go with the other inequality for the other condition:

- 4x + 26 > 6

Lest sum 4x in both sides to get a potive x:

- 4x + 26 + 4x > 6 +4x

26 > 6 +4x

Now subtract 6 in both sides

26 - 6 > 6 +4x - 6

20 > 4x

Finally, divide both sides by 4:

20/4 > x or 5 > x (simplifying we get the second)

So, our second condition says that x must be less than 5.

So, putting both conditions together:

x < 5

x < 31/3 = 10.33

So, if x must be less than 5 and less than 10.33, is the same that saying that x mus be less than 5. We con obviate the condition that x must be less than 10.33 as it is included in the other. So our answer is:

x < 5

It is the option B in the image (remember I didnt use the less or equal sign because you didn't included it in the statement).

Answer:

[tex]\large\boxed{y>\dfrac{c-ax}{b}}\\\text{for}\ a>0,\ b>0,\ c>0[/tex]

Step-by-step explanation:

[tex]ax+by>c\qquad\text{subtract}\ ax\ \text{from both sides}\\\\ax-ax+by>c-ax\\\\by>c-ax\qquad\text{divide both sides by}\ b\ (\text{we can, because}\ b>0)\\\\\dfrac{by}{b}>\dfrac{c-ax}{b}\\\\y>\dfrac{c-ax}{b}[/tex]

To solve the inequality ax - by > c for y, you first subtract ax from both sides which gives -by > -ax + c. Then you divide both sides by -b, remembering to flip the inequality sign, which gives y < (ax - c) / b.

To solve the inequality ax - by > c for y, you need to isolate y on one side of the inequality.

This is the solution for the inequality in terms of y.

Answer:

y - 2 = 3(x - 5)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = 3 and (a, b) = (5, 2), thus

y - 2 = 3(x - 5) ← equation of line

Answer:

y - 2 = 3(x - 5)

Step-by-step explanation:

Start with the general point-slope equation:

y - k = m(x - h)

Now substitute 2 for k, 5 for h and 3 for m:

y - 2 = 3(x - 5)

To solve 50 1/2 divided by 1/4, convert the mixed number 50 1/2 to an improper fraction (101/2), then multiply by the reciprocal of 1/4 (which is 4), resulting in 202. The numbers are related through these multiplication and division steps.

Step by Step Solution:

To understand how the numbers are related in the equation 50 1/2 divided by 1/4, follow these steps:

First, convert the mixed number 50 1/2 to an improper fraction. This is done by multiplying the whole number part by the denominator of the fractional part and adding the numerator. Therefore, 50 1/2 becomes:

50 × 2 + 1 = 101/2

Next, when dividing by a fraction, you multiply by its reciprocal. So, dividing by 1/4 is the same as multiplying by 4/1.

Now multiply the improper fraction 101/2 by 4/1:

(101/2) × (4/1) = 101 × 4 / 2 × 1 = 404/2

Simplify the result by dividing the numerator by the denominator:

404 / 2 = 202

Therefore, the numbers are related through these multiplication and division operations, confirming that 50 1/2 divided by 1/4 equals 202.

Step-by-step explanation:

  Inch   =   Cm

        1   =   2.54

       15   =   ?

We have to find out the question mark. So to do this we have to find out how we got from 1 to 15. We did this by multiplying by 15.

Inch   =   Cm

        1   =   2.54

×15

       15   =   ?

So we must do the same on the other side.

         1   =   2.54

×15                 ×15

       15   =   ?

2.54×15=38.1

   1   =   2.54

×15                 ×15

       15   =   38.1

The answer is therefore 38.1cm

Deb can use 6.5 ounces of cheese per loaf of bread. The calculation is made by dividing the total amount of cheese by the number of loaves.

Deb has 26 ounces of shredded cheese and she is making 4 small loaves of garlic cheese bread. To equally distribute the cheese across each loaf, we perform division.

We divide the total amount of cheese by the number of loaves: Thus, 26 ounces divided by 4 loaves equals 6.5 ounces of cheese per loaf.

The reasoning here is simple: we are equally distributing the cheese across each loaf, so we divide the total amount by the number of loaves. This ensures each loaf gets the same amount of cheese.

Prove that the area of the two small squares combined is equal to the area of the larger square

Step-by-step explanation:

The Pythagorean Theorem in an equation would be:

a² + b² = c²

Where:

c = hypotenuse (longest side of the triangle)

a and b = two other legs of the triangle

The theorem states that the sum of the squares of the shorter sides is equal to the square of the longest side in a right triangle or a triangle that has a right angle (90°)

Let's say that we have a right triangle with the lengths of 3cm , 4cm, and 5cm.

(3cm)² + (4cm)² = (5cm)²

9cm² + 16cm² = 25cm²

25cm² = 25cm²

Look at the attached image to see what happens when we draw the squares of each leg.

A statement that best describes how to translate the graph y = Ixl to obtain the graph of y = |x - 1| - 1 is: C. 1 unit right and 1 unit down.

In Mathematics, the vertex form of the equation for an absolute value function can be modeled by the following:

y = a|x - h| + k.

Where:

By critically observing the equation of the transformed absolute value function, we can logically deduce that the parent absolute value function y = |x| was horizontally shifted to the right by 1 unit and then vertically shifted 1 unit down as follows;
