Answer:-1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2(−x+4)−3x+2=−5
(−2)(−x)+(−2)(4)+−3x+2=−5(Distribute)
2x+−8+−3x+2=−5
(2x+−3x)+(−8+2)=−5(Combine Like Terms)
−x+−6=−5
−x−6=−5
Step 2: Add 6 to both sides.
−x−6+6=−5+6
−x=1
Step 3: Divide both sides by -1.
−x −1 = 1 −1 /x=−1

An airplane is flying at an altitude of 2.7 miles and is 8.3 miles from the runway. Find the angle of depression that the airplane must make to land safely.
Answers
Answer:
-8.72811548... i think
Step-by-step explanation:
a² + b² = c²
8.3² + 2.7² = c²
68.89 + 7.29 = c²
76.18 = c²
√76.18, -√76.18 = c
c = 8.72811548…, −8.72811548…
I think because it's depression, it's -8.72811548...
Dairy Delight offers a free ice cream every time that the saleperson does not greet the customer with a smile. Last year Dairy Delight gave away free ice cream 3.8% of the time. What is the probability of randomly selecting 3 customers from last year who all received a free ice cream? Round the answer to 6 decimals. Show your work below.
Answers
Answer:
0.000055
Step-by-step explanation:
Given that:
Percentage of free ice cream Given last year = 3.8%
From a total population of 1 ; proportion of those who received free ice cream = 3.8/100 = 0.038
Hence,
Probability of selecting a customer who received free Ice cream = 0.038
Hence, if 3 people are picked randomly from last year who received free ice cream:
(0.038 * 0.038 * 0.038) = 0.000054872
= 0.000055 ( to 6 decimal places)
In 2001, gold was priced at (0.5x + 300) dollars per ounce. Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to 2 3of the price in 2011.• Write an expression for the price of gold per ounce in 2016.• Explain how you found the expression. Write your expression and explanation in the space below
Answers
Given:
Price of gold in 2001 = (0.5x+300)
Its price tripled in 2008 and then doubled in 2011. In 2016, its price dropped to [tex]\dfrac{2}{3}[/tex] of the price in 2011.
To find:
An expression for the price of gold per ounce in 2016.
Solution:
We have,
Price of gold in 2001 [tex]= (0.5x+300)[/tex]
Its price tripled in 2008.
Price of gold in 2008 [tex]= 3(0.5x+300)[/tex]
Then doubled in 2011.
Price of gold in 2011 [tex]= 2\times 3(0.5x+300)[/tex]
In 2016, its price dropped to [tex]\dfrac{2}{3}[/tex] of the price in 2011.
Price of gold in 2016 [tex]=\dfrac{2}{3}\times 2\times 3(0.5x+300)[/tex]
[tex]=2\times 2(0.5x+300)[/tex]
[tex]=4(0.5x+300)[/tex]
[tex]=4(0.5x)+4(300)[/tex]
[tex]=2x+1200[/tex]
Therefore, the required expression for the price of gold per ounce is (2x+1200).

Answers
Answer:
this is a system of equations , and it's no surprise that it's tricky for you. these are tricky for anyone.
Step-by-step explanation:
X=adults
Y=children
I only know to make these two equations from experience doing these types of questions.
X+Y=800
7X +5Y=4600
there are a few ways to solve this , i"m just going to multiply the first equatlion by 7 and the subtract the 2nd from that whole equation.
7(X +Y=800)
7X +7Y = 5600
-(7X +5Y =4600)
0X +2Y = 1000
Y = 500 ( 500 children went to the movies )
by inspection you can probably see that 300 adults had to go too
500 kids
300 parents
also that's 4600 dollars to let those people in
7(300) + 5(500) = 4600
2100 + 2500 = 4600

C.B. Clothing ordered sweaters at a wholesale cost of $20 each. The store marked up the price 50 percent above the wholesale cost to use as their selling price. After every month that the sweater didn't sell, the store reduced the selling price by 20 percent. After how many monthly price reductions did the price dip below the wholesale cost?
Answers
Answer:
2 months
Step-by-step explanation:
The selling price of the sweater = 0.5 x $20 = $30
For every month that the sweater doesn't sell, price is reduced by 20% = 0.2 x $30 = $6
After the first month, price is reduced by $30 - $6 = $24
After the second month, price is reduced by $24 - $6 = $18

Find the x- and y-intercepts of the graph of the linear equation −4x+8y=−16.

The y-intercept is
Answers
Answer:
x-intercepts is (4,0)
y -intercepts is (0,-2)
Step-by-step explanation:
Using slope intercept form, x- intercept is (4,0) and y - intercept is (0,-2)
What is slope intercept form and how it can be used to find y and x intercept of the line?The slope intercept of a line is given by the equation y = m x+ c
y is y coordinate, x is x coordinate, m is the slope of the line
c is y- intercept of the line
y- intercept can also be found if a point on the line is given say (a, b) and slope is given .We put this point in the given slope intercept form and find c.
For finding x - intercept, put y = 0 in the equation and find value of x.
Given line -4x +8y = -16
Then add 4x both sides , we get
⇒4x+4x +8y = -16+4x
⇒ 8 y = 4x -16
Divide both sides by 8
⇒ y = (4/8) x - (16/8)
⇒ y = (1/2)x -2
Comparing this equation with y =mx+c
⇒ c =-2
Put y = 0 in the equation y = (1/2)x -2
⇒ 0 = x/2 -2
⇒2 = x/2
⇒4 =x
Therefore x- intercept is (4,0) and y - intercept is (0,-2)

6 ([tex]\frac{x}{2}[/tex] + 4) ≥ 9 ( distribute the parenthesis by 6 )
3x + 24 ≥ 9 ( subtract 24 from both sides )
3x ≥ - 15 ( divide both sides by 3 )
x ≥ - 5 → A
Answer:
A
Step-by-step explanation:
First, divide both sides by 6:
6(x/2 + 4) ≥ 9
x/2 + 4 ≥ 9/6
x/2 + 4 ≥ 3/2
Now, subtract 4 from both sides:
x/2 ≥ 3/2 - 4
x/2 ≥ -5/2
Finally multiply both sides by 2:
x ≥ (-5/2) * 2
x ≥ -5
The answer is thus A.

Given a rhombus ABCD with vertices A(2,6), B(6,7), C(5,3), and D(1,2). What would the coordinates of its image be if it was rotated 180° about the origin?
Answers
Answer:
The coordinates would be A(6,2), B(7,6), C(3,5), D(2,1)
Step-by-step explanation:
When conducting a 180 degree rotation, you can just reverse the points to get your answer.
The required coordinate of the rhombus when rotates around the origin by 180° is A(-2, -6), B(-6,-7), C(-5, -3), and D(-1, -2).
Given that,
Given a rhombus ABCD with vertices A(2,6), B(6,7), C(5,3), and D(1,2). What would the coordinates of its image be if it was rotated 180° about the origin is to be determined.
Coordinate, is represented as the values of positions on the x-axis and y-axis of the graph
here,
Given the coordinates of the rhombus, A(2,6), B(6,7), C(5,3), and D(1,2).
Now, after rotation through 180° around the origin is A(-2, -6), B(-6,-7), C(-5, -3), and D(-1, -2), because while rotating the rhombus it would go to the third quadrant.
Thus, the required coordinate of the rhombus when rotates around the origin by 180° is A(-2, -6), B(-6,-7), C(-5, -3), and D(-1, -2).

Ivan is getting ready for a long road trip. He wants to pack a few books from his collection of 5 novels and 7 collected short stories books. He asks his friend to select a book without showing. From the remaining books, Ivan then himself picks a random book, which turns out to be a novel. The third book that he randomly selects from the remaining ones is also a novel. Find the probability that Ivan will have 3 novels to read during the road trip.
Answers
Answer:
The probability that Ivan will have 3 novels to read during the road trip is 0.0455
Step-by-step explanation:
Given;
number of novels = 5
number of short stories = 7
total number of books = 12
The probability that Ivan's friend pick's a novel = 5 / 12
The probability of Ivan's first pick to be a novel = 4 / 11
The probability of Ivan's second pick to be a novel = 3 /10
The probability that Ivan will have 3 novels to read during the road trip is given by;
= p(Ivan's friend pick) and P(Ivan's first pick) and P(Ivan's second pick);
[tex]= \frac{5}{12}*\frac{4}{11}*\frac{3}{10}\\\\ = \frac{1}{22}\\\\ = 0.0455[/tex]
Therefore, the probability that Ivan will have 3 novels to read during the road trip is 0.0455
