Answer:
-12
Step-by-step explanation:
First you add five to the 19 and get 24 and then you divide -2x by 24 and you get -12
Answer:
x=-12
Step-by-step explanation:
-2x-5=19
+5 to both sides
-2x=24
÷-2 to both sides and you get -12

Starting at 6:00 a.m., Lin spent a day hiking through a canyon. This graph shows her elevation (in meters) at some different times. Negative values of x represent times earlier than noon, and positive values of x represent times later than noon.
Please help me with this
Answer:
First, we know that the 0 in the horizontal axis corresponds to the noon.
Then:
a) Lin's elevation at noon in meters.
We need to see the elevation when x = 0.
This is the point that is just on top of the y-axis, we can see that when x = 0, we have y = 6.
Then at noon, her altitude was 6 meters.
b) At 8:00 am, her elevation was 2m
Remember that the x-component represents time, and x = 0 represents the noon.
8:00 am is 4 hours before noon, then 8:00am is represented with x = -4
and at this time her elevation is 2m, then y = 2.
This means that the point that represents this is (-4, 2)
c) At 4:00 pm Lin was at sea level (her elevation was 0m)
Same reasoning than before: x = 0 is the noon, then 4:00 pm is four hours after this, then 4:00 pm is represented with x = 4.
And here her altitude is 0m, then y = 0.
This point is written as (4, 0)
d) Here we can see that at 6:00 am her elevation was negative, and at 4:00pm her elevation is 0.
And we know that:
0 > negative numbers.
Then her altitude increased in this interval of time.
Answer:
Its 0

There's 2 questions here that need to be answered.
Find the value of each variable.
Answer:
5. x= 13 y= 18.4
6.
Step-by-step explanation:
question 5:
tan45=x/13
multiply both sides by 13 to get x by its self.
end up with 13×tan45 so put that in the calculator to get x
then you do cos45= 13/y
multiply by y on both sides.
end up with y×cos45=13
divide the cos45 by both sides
put 13/cos45 to get y
question 6:
sin30=4/x
multiply x on both sides
end with x×sin30 =4
divide sin30 on both sides
put 4/sin30 in a calculator to get x
same thing again but with tan30 ahaha
A jeweler has several boxes of earrings to ship to a store. Each box is a cube with a side length of 5 centimeters. The jeweler packs the boxes in a shipping container. The filled container has 4 layers, where each layer contains 7 rows and 10 columns of boxes. What is the volume of the shipping container?
Answer: [tex]35,000\ cm^3[/tex]
Step-by-step explanation:
Given
The earring box has a volume of [tex]a=5\ cm[/tex]
It is packed and loaded in the container which has 4 layers and each layer has 7 rows and 10 columns
We can say that each layer can hold [tex]7\times 10=70\ \text{boxes}[/tex]
The volume of each earring box is
[tex]V_o=a^3=5^3\\V_o=125\ cm^3[/tex]
Four layers can hold [tex]4\times 70=280\ \text{boxes}[/tex]
the container can hold 280 boxes
[tex]\therefore \text{Volume of container is}\ V=280V_o\\\Rightarrow V=280\times 125=35000\ cm^3[/tex]

Answer:
the answer is 320
Step-by-step explanation:
just did the instruction
Answer:
320
Step-by-step explanation:
To find the volume, you multiply length times width times height, which is 3x1x2, which equals six. Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.

3n^3 - 12n^2 + 2n - 8
(show the work pls..)
Answer:
The answer will be ( n - 4 ) ( 3n² + 2 ).
Step-by-step explanation:
1) Factor out common terms in the first two terms, then in the last two terms.
[tex] {3n}^{2} (n - 4) + 2(n - 4)[/tex]
2) Factor out the common term n - 4.
[tex](n - 4)( {3n}^{2} + 2)[/tex]
Therefor, the answer is ( n - 4 ) ( 3n² + 2 ).
Sally has a discount card that reduces the price of her grocery bill in a certain grocery store by 6%. If c represents the cost of Sally’s groceries, which expression represents Sally’s grocery bill?
Answer:
Step-by-step explanation:
c - 0.06c = 0.94c
total bill = 0.94c
1/2 = 1/a + b/c make b the subject
Answer:
b = [tex]\frac{ac-2c}{2a}[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}[/tex] = [tex]\frac{1}{a}[/tex] + [tex]\frac{b}{c}[/tex]
Multiply through by 2ac to clear the fractions
ac = 2c + 2ab ( subtract 2c from both sides )
ac- 2c = 2ab ( divide both sides by 2a )
[tex]\frac{ac-2c}{2a}[/tex] = b

Answer:
Angle 1,Angle 4
Step-by-step explanation:
They're
The value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.
What are lines and angles?Lines are straight with little depth or width. Perpendicular lines, intersecting lines, transversal lines, and other types of lines will be covered. An angle is a shape formed by two rays emerging from a common point. In this field, you may also come across alternate and corresponding angles.
Given that there are two lines e and f cut by the transversal line g making different angles.
From the property of the alternate interior angles the two angles, 1 and 4 are congruent to angle 8. The value is mathematically written as,
∠1 = ∠4 = ∠8
Therefore, the value of angle ∠1 and angle ∠4 will be congruent with angle ∠8. The correct options are D.

write an equation of the line that passes through (0 0) and (2 6)
Answer:
y = 3x
Step-by-step explanation:
Slope equation:
y2 - y1
--------
x2 - x1
----------------------------------------------------------------------------------------------------------------
6 - 0 6
m = ----------- = ----- = 3
2 - 0 2
Your slope is 3.
----------------------------------------------------------------------------------------------------------------
Equation:
y = mx + b
Plug in the slope and you get:
y = 3x + b
----------------------------------------------------------------------------------------------------------------
Now to find b, you can use either coordinate point. So I will show you both ways :)
(0,0) (2,6)
0 = 3(0) + b 6 = 3(2) + b
Multiply 0 and 3 Multiply 2 and 3
0 = 0 + b 6 = 6 + b
Subtract 0 to 0 Subtract 6 from 6
0 = b 0 = b
There is no y-intercept
----------------------------------------------------------------------------------------------------------------
Your answer: y = 3x

A small town currently has a population of 15,000. Each year the population decreases by 2.25%. What will the population be in 8 years
Answer: 12,503 people
Step-by-step explanation:
This is an exponential decrease so to find the population in 8 years you have to use a future value formula:
= Amount * (1 + rate) ^ number of years
= 15,000 ( 1 + (-2.25%)) ⁸
= 15,000 * (1 - 2.25%)⁸
= 12,503.32
= 12,503 people

In the U.S., from 2004-2015, the correlation coefficient for the relationship between the size of a cell phone data plan, x, and the number of text messages sent, y, is r =0.97. Describe what this means about the relationship between the data plan size and the number of text messages sent in the U.S.
Answer options:
- There is no correlation between the size of the data plan and the number of text messages in the US.
- There is a weak positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong negative linear correlation between the size of a cell phone data plan and the number of text messages sent.
- There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.
I'd appreciate if you included an explanation, but an answer is fine.
Answer:
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.Step-by-step explanation:
We have r = 0.97
Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated (as per below table)r = (0.9, 1.0) very highly correlated. r = (0.7, 0.9) highly correlated. r = (0.5, 0.7) moderately correlated. r = (0.3, 0.5) low correlation. r = (0, 0.3) little to no correlation.Same applies to negative side
Correct choice is
D. There is a strong positive linear correlation between the size of a cell phone data plan and the number of text messages sent.To explain it in very simple way, consider a linear equation:
y = mx + bNumber of text messages is the linear function of the data plan. r = 0.97 shows this relationship is almost a perfect line with positive slope.
