Answer:

3 is not 4 is proportional

Step-by-step explanation:

Given:

Seven hot dogs and two hamburgers cost 14.50

Two hot dogs and seven hamburgers cost 17.00.

To find:

The cost of one hot dog and the cost of one hamburger.

Solution:

Let the cost of one hot dog be x and the cost of one hamburger be y.

According to the question,

[tex]7x+2y=14.50[/tex]       ...(i)

[tex]2x+7y=17.00[/tex]       ...(ii)

Multiply (i) by 7.

[tex]49x+14y=101.5[/tex]       ...(iii)

Multiply (ii) by 2.

[tex]4x+14y=34.00[/tex]       ...(iv)

Subtract (iv) from (iii).

[tex]49x-4x=101.5-34[/tex]  

[tex]45x=67.5[/tex]  

Divide both sides by 45.

[tex]x=1.5[/tex]  

Put x=1.5 in (i).

[tex]7(1.5)+2y=14.50[/tex]

[tex]10.50+2y=14.50[/tex]

[tex]2y=14.50-10.50[/tex]

[tex]2y=4[/tex]

Divide both sides by 2.

[tex]y=2[/tex]

Therefore, the cost of one hot dog is 1.5 and the cost of one hamburger is 2.

Answer:

(0, 2) or C

Step-by-step explanation:

The solution to the system of linear equations is (0,2). The correct option is C.

A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.

It is given that in a coordinate grid with 2 lines. The first line labelled f(x) passes through (-3, 3), (0,2), and (3, 1). The second line labelled g(x) passes through the points at (-3, 0) and (0, 2).

Plotting the two lines by using the points on the graph. After plotting the points there will be two lines that will intersect at the point ( 0, 2 ). Then the solution of the equation is ( 0,2).

Therefore, the solution to the system of linear equations is (0,2). The correct option is C.

Answer:

Step-by-step explanation:

In a unit rate, the denominator is always 1. So, to find unit rate, divide the denominator with the numerator in a way that the denominator becomes 1. For example, if 50km is covered in 5.5 hours, the unit rate will be 50km/5.5 hours = 9.09 km/hour.

Answer:

because unit rate means 1 hour not 3 hour.

Answer:

Step-by-step explanation:

Not a function

In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.

For

x2+y2=9

(for example)

x=0

there are two values for y (namely +3 and −3) which satisfy the equation

If you plug this graph into a calculator, you will find that it is a graph of a circle.

Circles have the formula x2+y2=r2 if they are centered at the origin.

From that, we can find that the radius is 3, and it is centered at the origin.

To find the domain and range, we just find the largest and smallest x and y values.

Since the radius is 3, and the graph is centered at the origin, the largest x value is 3. Similarly, the smallest x value is -3.

The domain is −3≤x≤3

We can use the same thing for the range. The radius is 3, so the largest and smallest values of the y will be 3 and -3.

The range is -3≤y≤3

Answer:

See below

Step-by-step explanation:

6. Look at the graph of the equation x^2+y^2=8. Give its domain and range.

7. Use algebraic means to show that x^2+y^2=8 is not a function. Explain your process.

8. Is there any value(s) of the domain of x^2+y^2=8 that passes the vertical line test? If so, name the value(s) and state whether or not the existence of this value makes this relation a function. You can use Desmos to help you explore this idea, if needed.

Answer:

Sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.

Step-by-step explanation:

A). Usual price of a sweat shirt is = $18

Sale price of the sweat-shirt is 85% of the usual price.

Therefore, Sale price = 85% of $18

=

= $15.30

B). Usual price of a soccer ball is = $24.80

Sale price of the soccer ball is 85% of its usual price.

Therefore, Sale price = 85% of $24.80

=

= $21.08

Therefore, sale price of a sweat shirt is $15.30 and a soccer ball is $21.08.

Answer:

MN = 2.8 units

Step-by-step explanation:

By the property of isosceles trapezoid,

1). Bases are parallel.

2). Base angles of an isosceles trapezoid are congruent.

2). Opposite sides of the congruent angles are congruent.

By third property,

Measure of side KL = Measure of side MN

2.8 = Measure of side MN

Another way to find the length of MN is,

Distance between M and N = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

MN = [tex]\sqrt{(3-1)^2+(0+2)^2}[/tex] = [tex]\sqrt{8}[/tex]

MN = 2.8 units

Therefore, MN = 2.8 will be the answer.

Answer:

The correct option is;

Never acute

Step-by-step explanation:

When an angle intercepts an ark, we have;

The legs of the angle meets with the endpoints of the arc

Therefore, given that the arc is greater than 180°, and that the angle of the arc is the angle defined at the center of the circle, while the angle defined by the inscribed angle is defined at the circumference of the circle

By circle theorem, the angle at the center is twice that at the circumference, whereby the angle of the arc > 180°, the angle at the subtended by the inscribed angle will > 180°/2, which is > 90° or an obtuse angle
