Which equation represents a proportional relationship

Answer:

-3

Step-by-step explanation:

Answer: -3

Step-by-step explanation: The additive inverse tells us that if we

add a number and the opposite of that number, the result will be 0.

So in this problem, 3 + (-3) = 0.

Answer:

A

Step-by-step explanation:

You must multiply the number your buying by the price then you need to multiply by 1.07 because you need 7% or .07 to get the tax but you want to add that to the old number so you need a 1 in front so the answer is c(p) = 1.07(3p) however you still need the $15 gift card so instead you add the 7% into the three dollars you are multiplying by the number then subtract the 15 dollars because you aren't really paying. The reasonable domain is 0 1 2 3 4 because the number 5 would be over the 15 dollar limit.

Answer:A coordinate system is a two-dimensional number line

Step-by-step explanation:

A coordinate system is a two-dimensional number line, for example, two perpendicular number lines or axes. An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x,y

The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

What is Coordinates?

A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.

Given that;

There are an ordered pair and coordinates.

Now,

The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

And, An ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of

(a, b) and a coordinate system is a two-dimensional number line.

Thus, The difference between an ordered pair and coordinates will be;

''Coordinates are used in geometry, and when there are two coordinates, they are ordered pairs when both component are of the same type.''

Answer:

D

Step-by-step explanation:

We have the set:

[tex]\{(2, -3), (-1,0), (0, 4), (-1, 5), (4, -2)\}[/tex]

Remember that the domain for a set of values is simply the input values.

In other words, our domain will be all of our x-coordinates.

We can see that our x-coordinates are: 2, -1, 0, -1, and 4.

So, our domain is:

Answer:

y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Step-by-step explanation:

Solve for y:

-4 y^2 - 3 x y + x^2 = 0

Hint: | Multiply both sides by a term to make the coefficient of y^2 positive.

Multiply both sides by -1:

4 y^2 + 3 x y - x^2 = 0

Hint: | Using the quadratic formula, solve for y.

y = (-3 x ± 5 sqrt(x^2))/8:

Answer: y = 1/8 (5 sqrt(x^2) - 3 x) or y = 1/8 (-3 x - 5 sqrt(x^2))

Answer:

The answer is: (x , y) = (19/10 , 1/5)

Step-by-step explanation:

Solve the equation for y-

y = 4 - 2x

4x - 3y = 7

Substitute the given value of y into the equation-

4 x - 3 ( 4 - 2x ) = 7

Solve the equation for x-

x = 19/10

Substitute the given value of x into the equation y = 4 - 2x-

y= 4 - 2 * 19/10

Solve the equation for y-

y = 1/5

The possible solution of the system is the ordered pair ( x , y )-

( x , y ) = ( 19/10 , 1/5)

Check if the given ordered pair is the solution of the system of equations-

{2 * 19/10 + 1/5 =4

4 * 19/10 - 3*1/5 =7}

Simplify the equalities-

4 = 4

7 = 7

Since all equalities are proven true the ordered pair is the solution of the system-

( x , y) = (19/10, 1/5)

FINALLY haha the solution is: ( x , y ) = (19/10 , 1/5)

Answer:

Bed A --- Third Option

Bed B --- Fifth Option

Step-by-step explanation:

Flower Bed A)

The formula for circumference is:

[tex]C=2\pi r[/tex]

The diameter of A is 10 feet. So, its radius is 5 feet.

Substitute 5 for r. So, the circumference of Bed A is:

[tex]C=2\pi (5)=10\pi\text{ feet}[/tex]

The formula for the area of a circle is:

[tex]A=\pi r^2[/tex]

Substitute 5 for r:

[tex]A=\pi (5)^2[/tex]

Square and simplify:

[tex]A=25\pi \text{ square feet}[/tex]

So, the circumference of Bed A is 10π feet and its area is 25π square feet.

Therefore, match Bed A to the third option.

Flower Bed B)

The radius of Bed B is 6 feet. Again, we can use the circumference and area formulas. Substitute 6 for r for circumference:

[tex]C=2\pi (6)[/tex]

Multiply:

[tex]C=12\pi\text{ feet}[/tex]

Substitute 6 for r for the area formula:

[tex]A=\pi(6)^2[/tex]

Square and simplify:

[tex]A=36\pi\text{ square feet}[/tex]

So, Bed B has a 12π feet circumference and a 36π square feet area.

Therefore, match Bed B to the fifth option.

And we're done!

Answer:he team advisor randomly chooses 4 students to debate in the next competition. How many different ways can a team that includes Joseph, Malena, Carlos, and Abby be chosen? ... If two angles are congruent, then they are vertical angles.

Step-by-step explanation:

Answer:

11. ∠9 = 100°

12. ∠6 = 80°

13. ∠8 = 80°

14. ∠2 = 80°

15. ∠5 = 100°

16. ∠11 = 100°

Step-by-step explanation:

Answer:

11. 100°    12. 80°     13. 80°    14. 80°    15. 100°    16. 100°      

Step-by-step explanation:

We know a straight line is 180 degrees and that m∠7 is 100 degrees.

m∠9, m∠5 and m∠11 are 100 degrees

To find m∠6, m∠8, and m∠2 we subtract 100 from 180 and get 80 degrees.

If you fill in all the degrees of the angles, you will notice a zig-zag pattern. That helps when solving these kinds of problems

f(-3)=-17

Step-by-step explanation:

Substitue -3 for t

-2(-3)^2 + 1

Simplify

-2(9) + 1

-18 + 1

Answer: -17

A function is defined as a relation between a set of inputs having one output each.

The value of the function f(t) = -2t² + 1 at t = -3 is -17.

The domain of the function is -17.

The range of the function is -3.

A function is defined as a relation between a set of inputs having one output each.

f(x) = x + 2

At x = 2,

f(2) = 2 + 2 = 4

Domain = 2

Range = 4

We have,

f(t) = -2t² + 1

We need to find for t = -3.

f (-3) = -2 ( -3 )² + 1

[ -3 x -3 = 9 ]

f (-3) = -2 x 9 + 1 = -18 + 1 = -17

Thus the value of the function f(t) = -2t² + 1 at t = -3 is -17.
