Answer:
you would move left once, then left again 6 times. so 7 times to the left.
Step-by-step explanation:
You're moving left because you're working with negative numbers, so -1 would be the first step, and then just move 6 times more to the left. When you work with positives you do the same but to the right.
You will have to move left by 6 units.
What is equation modelling? What is a mathematical equation and expression?Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Given is a number line.
The given expression is -
-1 + (-6)
on solving, we get -
- 1 - 6
- 7
You will have to move left by 6 units.
Therefore, you will have to move left by 6 units.

Answer:
9. not possible
13, 14, 19. AAS — 13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
15, 16. not possible
Step-by-step explanation:
9. You're looking for three sides, or two sides flanking a congruent angle. Here, the angle is not between the two sides, so the SAS theorem does not apply. Proving congruence is not possible.
__
13, 14, 19. You have two adjacent angles, followed by a side, so the AAS theorem will prove congruence.
When you write the congruence statement, you need to make sure the nodes are named in corresponding order. It can be useful to name the nodes in the same order as the elements you claim for congruence. For these, we name the two angle nodes first, then the other end of the side.
13: WYX≅AYZ; 14: CFD≅CEB; 19: DEH≅GEF
__
15, 16. With only one angle and one side, it is not possible to prove congruence.
_____
Additional comment
With these theorems, you are looking for angles or sides that are adjacent (next to each other). In figure 9, there are two sides and an angle, so you might be tempted to claim SAS congruence. The name SAS means the angle must be between the two sides. In that figure, the two sides are adjacent, and the angle is adjacent to only one of the sides (not between them). Hence SAS does not apply.
(You will find later that two sides and a non-adjacent angle will define a unique triangle if, and only if, the angle is opposite the longest of the two given sides. In figures like these, no side lengths are given, and you are not allowed to rely on appearances.)

Ulani is constructing a triangle that has sides measuring 12 cm and 28 cm. Which measurements could be the length of the third side? Select two options.
Answer:
16 < n < 40
Step-by-step explanation:
use triangle inequality theorem:
n = length of third side
12 + 28 > n; n > 40
12 + n > 28; n > 16
n + 28 > 12 (this inequality can be discounted because it results in a negative)

Step-by-step explanation:
plug 5x into y since y=5x:
5x=4x+9
-4. -4
x=9
5(9)=45
Answer:
x=9 y=45
Step-by-step explanation:
y=4x + 9.......(1)
y= 5x.........(2)
Substitute 5x for y in equation 1.
5x= 4x + 9
5x - 4x = 9 (Collect like terms 5 and 4 have x in common if +4 crossover it changes to -4)
x = 9
substitute 9 for x in equation 2.
y = 5(9)
y = 5 x 9(multiplication)
y = 45
karen purchased a DVD player on sale. The original selling price was $159.92 The sale price was $179. 30 find the percent markdown
Answer:
Step-by-step explanation:
Answer:
19.26%
Step-by-step explanation:
Given the original selling price of DVD player as $179.30 and the new sale price to be $144.77, the the first step in finding the percent markdown is to take the difference between the original selling price and the sale price to give $179.30 - $144.77 = $34.53
Percent markdown = original selling price- new sale price/original selling price × 100%
Percent markdown = $34.53/$179.30 × 100%
% markdown = 19.26%

please help, can't understand.
Step-by-step explanation:
Angle ACO = 140° - x. (Sum of angles in a triangle is 180°)
Now draw the line OD. The triangles ODC and OBC are congruent via the SSS congruence property. (OD and OB are both the radius of semicircle, common side OC, and side CD = CB is given)
Hence Angle BCO = Angle ACO = 140° - x.
Since triangle OBC is an isosceles triangle with OC = OB, this means that Angle CBO is also 140° - x.
By Exterior Angle theorem,
we have Angle AOC = Angles BCO + CBO
=> x = (140° - x) + (140° - x)
=> 3x = 280°
=> x = 280°/3. (B)

The grizzly bear population in Yellowstone National Park in 1970 was about 270. Over the next 35 years, it increased by about 115%. What was the population in 2005?
Answer: 311 bears
Step-by-step explanation:
Population increased by 115% in the 35 years from 1970 to 2005.
Population in 2005 is:
= 270 * 115/100
= 310.5
= 311 bears
Answer:
581
Step-by-step explanation:
270x%115=310.5
We have to round 310.5 to the nearest So 310.5 will be 311
So if it increased by 115% we have to add the 115% to 270
270+311= 581
By the 2005 the population will be 581

Which of the following expressions would give a sequence with a first term of 2 and a common difference of 5? 2 - 5 n 2 n - 5 5 n - 3 5 n + 2
9514 1404 393
Answer:
5n -3
Step-by-step explanation:
Try n=1 in each expression and see which gives you a first term of 2.
2-5n = 2-5·1 = -3
2n -5 = 2·1 -5 = -3
5n -3 = 5·1 -3 = 2 . . . . . this is the expression you want
5n +2 = 5·1 +2 = 7

For a common difference of 5, the coefficient of n must be 5. The second answer choice fails on that count also.

Maria's bill for lunch was $12.25. How much would her tip be if she leaves a 20% tip?
Answer:
$2.45
Step-by-step explanation:
First, we find how much 20% of 12.25 is:
we can convert 20% directly to a decimal:
20% = 0.2
Then we find
20% of 12.25 = 0.2 x 12.25 = 2.45
So Maria's tip would be $2.45

During its first year, there were 138 volunteers at a community outreach program. Over the next 2 years, there were 156 volunteers and 175 volunteers, respectively. What is the percent of increase in volunteers from Year 1 to Year 2 and from Year 1 to Year 3? Round to the nearest tenth percent if necessary.
Answer:
0.1%
Step-by-step explanation:
138 into a percent=1.38%
156 into a percent=1.56%
175 into a percent=1.75%
1.38-1.56=0.18
1.56-1.75=0.19
0.19-0.18= 0.1%
The increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.
PercentageThe percentage can be defined as a relative value that represents the hundredth part of any quantity.
Given that the number of volunteers in a program during year 1, year 2 and year 3 are 138, 156 and 175 respectively.
The percentage of increase in volunteers from year 1 to year 2 is given below.
Volunteers (%) = [tex]\dfrac {156-138}{138} \times 100[/tex]
Volunteers (%) = 13.04%
The percentage of increase in volunteers from year 1 to year 3 is given below.
Volunteers (%) = [tex]\dfrac {175-138}{138} \times 100[/tex]
Volunteers (%) = 26.81 %
Hence we can conclude the increase in volunteers from year 1 to year 2 is 13.04 % and the increase from year 1 to year 3 is 26.81 %.
