Jasmine works at the public library after school. She makes $7.00 per hour. She cannot work more than 15 hours per work. If y=7x represents Jasmine's earning, what are the values in the domain?
A. x (greater than or equal symbol) 15
B. All real numbers.
C. 0 (greater than or equal to symbol) x (greater than or equal to symbol) 15
D. 1 (greater than or equal to symbol) x (greater than or equal to symbol) 15

Answer: Subtract 18 on both sides is wrong. Its supposed to be add 18 on both sides.

Answer:

-159

Step-by-step explanation:

Answer:

For the first one

x= About 32.02

y= About 27.58

z= About 55.16

For the second one

x= 6

y= 12

z= about 16.97

Step-by-step explanation:

Their all really simple

These are special right triangles, a 45, 45, 90 and a 30, 60, 90 triangle. The formla for these triangles are shown in the picture below.

Now for the first one ]

Lets find Z first

Now this is a 45 special right triangle so we know the other side s 39 but the hypotenuse is n[tex]\sqrt{2}[/tex] (I’m using N becuase x and y is taken) So n is basically 39 (look at the image below) and just solve that. Now for x and y. We know its a 30, special right triangle. We know that 39 here is already the answer for  N[tex]\sqrt{3}[/tex] so make an equation to find the n and you’ll get 27.58 for y. Now For x, its just doubled the y.

For the second one this is easier

We know that the x is (6) becuase its already in the radical number, now to find the hypotnuse, we double that and get 12. Now we know what y is becuase since the 2nd triangle is a 45/45/90, we know that 12 is y, the hypotnuse is just N[tex]\sqrt{2}[/tex] and we just plug in the n with 12 and solve it!

The graphical function representation of a function, represents the mapping of the domain of the function to the range of the function

The sum of the coordinates of the point is 7.25

The reason the above values are correct is as follows;

The given parameter is;

The point (9, 7) is on the graph y = f(x)

Required:

A point on the graph, 2·y = (f(2·x)/2) + 2

Solution:

Let x = 9/2, given that (9, 7), is on the graph, f(x), we get;

f(2·x) = f(2 × 9/2) = f(9) = 7

Therefore;

2·y = (f(2·x)/2) + 2 = (7/2) + 2) = 5.5

y = 5.5/2 = 2.75

y = 2.75

The coordinate of the point is (x, y) = (2.75, 9/2)

The sum of the coordinates of the point is 2.75 + 9/2 = 7.25

Answer:

C

Step-by-step explanation:

Answer:

Density is defined as mass per unit volume:

density = mass/volume

Density can be calculated using the mathematical formula (expression):

d = m ÷ V

where d = density, m = mass, V = volume

The greater the density, the more mass per unit volume.

The unit of density derived from SI units is kilograms per cubic meter, kg/m3 or kg m-3.

More commonly, densities are given in g/mL (g mL-1) or g/cm3 (g cm-3 or g/cc).

Density is a characteristic property of pure substances so density can help identify a particular pure substance.

Since different substances have different densities, density can also be used to separate one substance from another.

In general, solids are more dense than liquids which are more dense than gases:

density of solid > density of liquid > density of gas

Step-by-step

Answer:

0.338 g/mL

Step-by-step explanation:

Density is the mass per unit volume of any object. It is calculated by dividing the mass of an object by its volume. This is:

ρ = m/V

ρ = 4.05 g  / 12 mL

ρ = 0.3375 g/mL

ρ ≅ 0.338 g/mL

Answer:

1. QS and RT= 15

2. Im not positive but I think it's TQ=18

Step-by-step explanation:

For question 1, you would do 6x+3=8x-1 and solve to get the result of x=2

Then you'd plug in 6 and get QS and RT=15

For the second one I am unsure because I wasn't positive how to solve but it seems like the side RQ might be 1/2 of TQ. Sorry if thats wrong I can try and help more if you need

Answer:

x=2

Step-by-step explanation:

x+(-4) is the same as x-4

First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.

x-4=-2

+4    +4

x= -2+4                or you can see this as 4-2 which is 2

x=2

Answer:

Let a = the larger number and b = the smaller

a + b = 14

a - b = 18

We can add the 2 equations together.

2a = 32

2a/2 = 32/2

a = 16

Answer:

A = (-2 , -1)                 A’ = (-5 , -1)

B = (2 , -1)                  B’ = (-1 , -1)

Step-by-step explanation:

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!
