[tex]n - 12 = 3n[/tex]
please I need help
Answer:
n = -6
Step-by-step explanation:
n -12 = 3n
2n = -12
n = -6
Answer:
n=-6
Step-by-step explanation:
So first, you should subtract n from both sides to isolate the number -12. This will make the equation look like 2n=-12. Divide both sides by 2 because you want n to be by itself. This will give you the answer n=-6

Today, the price of a new cell phone is $129.
In 2000, the price of a similar cell phone was $240.
What is the percent of change in the price of a cell phone from 2000 to today? Round to the nearest whole percent.
Answer:
54%
Step-by-step explanation:
129/240 = 0.5375 (divided to find the % change)
0.5375 * 100 (to convert decimal to percent form)
53.7 which is rounded to 54 percent (I needed to round it to the nearest whole percent number)
Which lines are parallel?
Answer:
C)?
Step-by-step explanation:
Find the percent of change from 160 cups to 404 cups.
Answer:
the answer to that question is 152.5%
Step by Step Explanation:
(404 - 160)/|160| =
244/160 =
244 ÷ 160 =
244 ÷ 160 × 100/100 =
(244 × 100 ÷ 160)/100 =
(24,400 ÷ 160)/100 =
152.5/100 =
152.5%
Question 4 please. I will mark brainliest!! i would at least like the equation of the graph thank you
Answer:
a. -3 < x ≤ 5
b. -3 ≤ y < 3
c. (0, 0)
d. x = -3, x = 1, x = 5
e. -3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. (-1, -1), and (3, -3)
Step-by-step explanation:
a. The domain of a function is the set of the possible independent variable values which is -3 < x ≤ 5
b. The range of a function is the set of the possible values of the dependent variable which is -3 ≤ y < 3
c. The y-intercept is the point the graph crosses the y-axis
The y-intercept in the graph is the point (0, 0)
d. f(x) ≥ 0 when x = -3, x = 1, x = 5
f(x) ≥ 0 over the following range; -3 < x ≤ - 1.5, 0 ≤ x ≤ 1.5, 4.5 ≤ x ≤ 5
e. The intervals over which f(x) is decreasing are;
-3 < x ≤ - 1, and 1 ≤ x ≤ 3,
f. The local minimums where f(x) has the minimum values are;
(-1, -1), and (3, -3)
Draw the graph of the equation
g(x) = -3x +2.
You can refer to the section "Drawing Graphs in Mobius" in the unit "Introduction to
Mobius" for
practice in drawing graphs of lines in Mobius.
Part a: Find one point on the line. Often it's smart to start with the value x = 0 because multiplying by
and adding 0 are easy. In other words, find the y-intercept.
The point (0, Number ) is on the line g(x) = -3x + 2.
Part b: Find a second point on the line. Often it's easier to continue with the value x = 1 as multiplying
by and adding 1 are pretty easy.
The point (1, Number ) is on the line g(x) = -3x +2.
Use DESMOS to graph any function online.
The picture shows the graph of g(x) = -3x + 2.

1. What is the solution to the inequality 10x > 140? Show your work
A. X > 14
C. x > 130
B. x < 14
D x <130
I
Answer: A. X > 14
Step-by-step explanation:
1. 10x > 140. We need to eliminate that 10 so it is just X. So, we divide both numbers.
2. 10 / 10 = 1, so it just becomes x
3. Now, we divide the other side.
140 / 10 = 14

Pennsylvania has a sales tax of 6%. The city of Philadelphia adds an extra local sales tax of 2%. Both taxes apply to the original price of an item. If the shelf price of a bottle of sports drink is $2 in Philadelphia, PA, which expressions can be used to show the total taxes you would expect to pay?
Answer:
For the regular tax in Pennsylvania, it would be 12 cents or $0.12. For Philadelphia, it would be 4 cents or $0.04. I got these two amounts by multiplying 2 times 6 or 2 percent, aka 0.06 and 0.02. If you added the two together, you would get, $0.16 or 16 cents. You would then add that to the two dollars and end up with $2.16 or two dollars and sixteen cents. I hope this helps.

1.62 and -0.62
Step-by-step explanation:
v² - v - 1 = 0
From ax² + bx + c = 0
a = 1 b = -1 c = -1
Quadratic formula
x = -b +/- √b² - 4ac
--------------------------
2a
x = -(-1) +/- √-1² - 4 x 1 x -1
-----------------------------------
2(1)
x = 1 +/- √1 +4
-----------------
2
x = 1 +/- √5/2
x = 1 + √5/2 or x = 1 - √5/2
x = 1.618 or -0.618
The graphs below were created by an advertising agency for the computer store TechPlus to show its average price on laptops and desktops compared to another computer store's prices.
Which of the following statements best explains how the advertising agency misrepresented the data?
The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
The graphs were created with different colors.
The graph for CompStar makes its prices appear much higher, but its prices are only a little higher.
The graphs do not include tablet computers, so there is not enough information to compare their prices.
The misrepresentation lies in the fact that ; The graphs use different scales, making it appear that the prices at TechPlus are much lower than CompStar.
Taking a look at both graphs, it could be observed on the y - axis that the graphs do not follow the same scale.
For CompStar, the y-axis which shows the price of laptops and desktops starts it's labeling from $0 ; while TechPlus's labeling began from $600
This representation means that comparing the two graphs would give an erroneous inference as it would make the price of TechPlus appear lower than that of Complus.

Decrease R1400 in the Ratio 7:3
Answer:
Step-by-step explanation:
It's hard to tell what you mean. I'm going to assume you mean that you want what is left to be 3/7 less.
1400 - 3/7 1400 = 1400 - 600 = 800
The value of R1400 when decreased by the ratio 7:3 is R600.
What is the value of R1400 when it is decreased?Ratio expresses the relationship between two or more numbers. It shows the number of times that one value is contained in another value.

what is the measure of angle x?
Answer:
C
Step-by-step explanation:
first we want to find the missing angle at the top
to do that we subtract the given angles by 180
the square indicates that the angle is a right angle or that it equals 90
180-90-40=50
we know that the angle equal to 50 and x are supplementary angles so they will add up to equal 180 so to find x we subtract 50 from 180
180-50-130 so the answer is c
have a great day :D
