f K = {(x, y) | x - y = 5}, is Set K a function?

Answer:

I believe it's the second one

Step-by-step explanation:

A dilation factor of 1/2 and reflection across the x-axis that triangle JKL is dilated to form triangle  J'K'L' which is the correct answer would be an option (C)

Dilation is a process for creating similar figures by changing the size.

A graph can be defined as a pictorial representation or a diagram that represents data or values.

Here triangle JKL is dilated to form triangle J'K'L

Given that the coordinates for each of the shapes:

Regular:

J = -8, 6

K = -4, 6

L = -6, 2

Prime notation:

J' = -4, -3

K' = -2, -3

L' = -3, -1

We have to determine the dilation factor.

As we know dilation factor is the ratio of sides in the original image and the image after dilation.

Dilation factor = J'K'/JK

Dilation factor = 2/4 =  1/2

Hence, a dilation factor of 1/2 reflection across the x-axis that triangle JKL is dilated to form triangle  J'K'L'

#SPJ2

Answer:

C. 50 deg

Step-by-step explanation:

m(arc)BDC = 260 deg

Since a full circle has an arc measure of 360 deg, we can find the measure of arc BC.

m(arc)BC = 360 deg - 260 deg = 100 deg

Angle 1 is formed by a tangent to the circle and a chord of the circle and has a vertex on the circle. Its measure is half the measure of the intercepted arc.

m<1 = (1/2)m(arc)BC = (1/2) * 100 deg = 50 deg

Answer: C. 50 deg

Answer:

y = -2x+5

Step-by-step explanation:

y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept

-2 is the slope

Parallel lines have the same slope so our new line will have the same slope

y = -2x+b

The point given is the y intercept (value when x is zero)

b = 5

y = -2x+5

Your answer would be the last option, 0.71.

To find the probability of the next pizza not being a cheese pizza, we need to find how many pizzas in the sample weren't cheese by adding them up. This gives us:

14 + 23 + 14 = 51

The total number of pizzas made is 21 + 14 + 23 + 14 = 72.

Therefore the probability of not making a cheese pizza would be 51/72 = 0.708 = 0.71

Answer:

D

Step-by-step explanation:

When an expression is divided by its factor, there are no remainders.

Let's look at the number 6.

6= 1(6)= 2(3)

Thus, the factors of 6 are 1,2,3 and 6.

This is because 6 is divisible by all those numbers to give no remainders.

Let's look at the question again.

D. 2(x-a) is divisible by (x-a) since

[tex] \frac{2(x - a)}{x - a} = 2[/tex]

A.

[tex] \frac{ - (x + a) - 2}{x - a}[/tex]

This fraction cannot be simplified further

B.

[tex] \frac{ - 2(x + a)}{x - a} [/tex]

This fraction cannot be simplified either

C.

[tex] \frac{(x - a) + 2}{x - a} \\ = \frac{x - a}{x - a} + \frac{2}{x - a} \\ = 1 + \frac{2}{x - a} [/tex]

There is a remainder of 2 since 2 cannot be divided by (x-a). Thus, (x-a) is not a factor of this fraction.

Answer: A

Step-by-step explanation:

For a system of equations to have no real solution, the lines of the equations must be parallel to each other. The correct option is A the lines have different slopes.

Inconsistent System

For a system of equations to have no real solution, the lines of the equations must be parallel to each other.

Consistent System;

For a system of the equation to be a Dependent Consistent System, the system should have multiple solutions for which the lines of the equation must be coinciding.

For a system of the equation to be an Independent Consistent System, the system should have one unique solution for which the lines of the equation must intersect at a particular.

If the two of the given system of equations are plotted on the graph, y = 2x – 3, y = –3

Then it can be seen that the two lines have different slopes. Therefore, the correct option is A.

Your answer would be the second option, (-4,5).

We can find this by substituting in each point into the equation y < |x - 3| and seeing if it is true.

For the first one you get 1 < |2 - 1|. |2 - 1| = |-1| = 1, and 1 cannot be less than itself, so this is false.

For the second one you get 5 < |-4 - 3|. |-4 - 3| = |-7| = 7, and 5 is indeed less than 7, so this is correct.

Answer:

Add 4 to 17, then divide both sides by 3.

Step-by-step explanation:

Given that :

Suri's age is 4 less than 3 times her cousin's age

Suri is 17 years old

Let her cousin's age be c

Then ;

3c - 4 = 17

By adding 4 to 17; we have

3c = 17 + 4

3c = 21

Now, dividing both sides by 3 ; we have

3c/3 = 21/3

c = 7

The age of her cousin is 7 years

Answer:

Algebraic equation

Step-by-step explanation:

We would use an algebraic equation.

An algebraic equation is a mathematical statement in which two expressions are made equal to each other using the equal sign.

In this case the algebraic equation consists of constant, variables and algebraic operation.

One of the type of algebraic equation is a linear equation. The expression below relating suri's age with her cousin's is a linear equation.

We can derive equations from sentences that involves unknown values by representing them with variables such as x, y, etc.

Suri's age = 17years old

Let Suri's cousin's age = x

3 times her cousin's age = 3x

Suri's age = 4 less than 3 times her cousin's age = 3x-4

17 = 3x-4

3x = 17+4 = 21

x = 21/3

x = 7

Her cousins age = 3x = 3×7

Her cousins age = 21 years

Final answer:

The bicycle should be worth a value of $79.16 after 6 years.

Explanation:

To calculate the value of the bicycle 6 years later, we need to find the depreciated price. The bicycle depreciates at a rate of 15% per year, so after 6 years, it will be worth 85% of its original value.

First, we calculate the value after one year: $250 * 0.85 = $212.50. Then, for each subsequent year, we multiply the previous year's value by 0.85 to calculate the new value.

Therefore, the bicycle should be worth $212.50 * 0.85 * 0.85 * 0.85 * 0.85 * 0.85 = $79.16 after 6 years.

Have a great day guys. ✌

Step-by-step explanation:

The probability of picking a 5 or an even number is [tex]\dfrac{5}{9}[/tex].

Important information:

One card of number 5 between 1 and 9.

Even cards between 1 and 9 are 2, 4, 6, 8.

Possible outcomes for picking a 5 or an even number is 4 + 1 = 5.

Total number of cards is 9.

The probability of picking a 5 or an even number is:

[tex]P=\dfrac{5}{9}[/tex]

Answer:

[tex]221.4m^{3}[/tex]

Step-by-step explanation:

To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4[tex]m^{3}[/tex]

1) Multiply 12 by 4.1.

[tex]12*4.1=49.2[/tex]

2) Divide 49.2 by 2.

[tex]49.2/2=24.6[/tex]

3) Multiply 24.6 by 9.

[tex]24.6*9=221.4m^{3}[/tex]
