Write the equation of a line with a slope of -2 and a y-intercept of -5
Answer:
y = -2x - 5
Step-by-step explanation:
y = is a standard for any equation, as is the use of x as a variable, unless something else is specified.
-2x is the way to denote a slope of -2, and -5 gives you the y-intercept of 5. One point on this line would be (0, -5).

Mrs. Jones decided to buy some pencils for her class. She bought 4 packages of pencils, and each package contained 57 pencils. There are 19 students in her class and she divided up the pencils so that each student had the same amount of pencils. If there were no pencils left over, how many pencils did each student get?
Answer:
The correct answer is 19 pencils.
Step-by-step explanation:
First, we have to multiply
57 x 4 = 228
Second, we have to divide
228 ÷ 19 = 12

Reaserch how x ray technications use math in their careers
Answer:
X-ray technicians, also referred to as radiologic technologists, would need math skills to be able to use accurate calculations when mixing chemicals used in x-ray imaging processes. In addition to this, the critical and logical thinking abilities practiced in the study of mathematics are useful in the day to day job, especially because working with imaging technology and machines to get detailed images for physicians to view is crucial to patient care and treatment.
Education for an associate's degree in radiologic technology is going to be focused heavily on STEM related courses such as anatomy, radiation safety, imaging procedures, and pathology. For this reason, it is recommended that high school students planning on pursuing this educational path take plenty of classes in math, science, and technology.
Radiologic technology job opportunities are expected to increase by 9 percent between 2018 and 2028 according to the Bureau of Labor and Statistics. This is greater than the 5 percent average increase projected for all other jobs, which means radiological technology is a career with a strong and stable outlook.

Step-by-step explanation:
Because they are scaled copies, the ratios of the sides are equal.
Figure A has a base of 6 units by inspection.
Figure B has a base 3 units by inspection.
So, the scale factor from Figure A to Figure B is [tex]3/6=\boxed{1/2}[/tex] and we're done!
The scale factor from Figure A to Figure B is 1/2
What is the scale factor from Figure A to Figure B?Figure A:
Base = 6 units
Height = 4 units
Figure B:
Base = 3 units
Heights = 2 units
Using Base of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 3 units / 6 units
= 1/2
Using Height of the shape:
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape
= 2 units / 4 units

Answer:
x= 1
Step-by-step explanation:
TO solve you can use the equation 50x+10=70x-10.
First, subtract 10 from both sides:
50x= 70x-20
Then subtract 70x from both sides:
-20x=-20
Then divide by -20:
x=1

EASY IVE DONE IT
Using conversion of units and the relationship between velocity, distance and time, it is found that the distance between the two stations is of:
c. 454 kilometers
Velocity is distance divided by time, that is:
[tex]v = \frac{d}{t}[/tex]
In this problem:
Time of 6 hours, hence [tex]t = 6[/tex].Velocity of 21 m/s. To convert from m/s to km/h, we multiply by 3.6, hence [tex]v = 21(3.6) = 75.6[/tex]Then, solving for the distance:
[tex]v = \frac{d}{t}[/tex]
[tex]75.6 = \frac{d}{6}[/tex]
[tex]d = 6(75.6)[/tex]
[tex]d = 453.6[/tex

The inequality is x/5 < 20, and 100 is in the box.
Step-by-step explanation:
x = the amount she spends in June.
So, since she spends an equal amount five times, the amount she spends each time is x/5.
She wants this to be less than 20.
So, x/5 < 20.
Solving for x by multiplying both sides of the equation by yields
x < 5 * 20
x < 100, so that 100 goes into the box.

Answer:
2x° + 10° = 90°
3x° = 120°
2x° + 5° = 85°
2x° - 15° = 65°
Step-by-step explanation:
360° = 3x° + 2x° + 5° + 2x° + 10° + 2x° - 15°
360° = 3x° + 2x° + 2x° + 2x° + 5° + 10° - 15°
360° = 9x°
9x° = 360°
x° = 360° : 9
x° = 40°
2x° + 10°
= 2(40°) + 10°
= 80° + 10°
= 90°
3x°
= 3(40°)
= 120°
2x° + 5°
= 2(40°) + 5°
= 80° + 5°
= 85°
2x° - 15°
= 2(40°) - 15°

4. Identify the graph of the solution set of 9 > 3 + 2x.
Answer:
A
Step-by-step explanation:
9 > 3 + 2x
6 > 2x
3 > x
or
x < 3
and that means 3 is NOT included (otherwise there must be a smaller or equal sign). hence A is the right answer.
The graph of the solution set [tex]9 > 3 + 2x[/tex] is represented by the inequality relation x < 3.
The correct answer is Option A.
Given data:
The inequality is represented as 9 > 3 + 2x
The solution set of the inequality 9 > 3 + 2x can be found by isolating x on one side of the inequality:
Subtract 3 from both sides: 9 - 3 > 2x
Simplify: 6 > 2x
Divide both sides by 2: 3 > x
So, the solution set is x < 3.
Graphically, this represents all the values of x that are to the left of (less than) 3 on the number line. It forms an open interval to the left of 3. The graph consists of all real numbers less than 3, not including 3 itself. In interval notation, this can be written as (-∞, 3).
Hence, the inequality is x < 3.
