Simplify: (-7x - 5) - (-9x2 + 8x + 7). Choose the standard form of the answer.
Answer:
-15x - 12 + 9x^2
Step-by-step explanation:
(-7x - 5) - (-9x^2 + 8x + 7)
-7x - 5 + 9x^2 - 8x -7
-15x - 12 +9x^2
what is that 2 by the 9x
We will simplify the given expression to get:
9x^2 - 15x - 12
How to simplify the given expression?
Here we have the expression:
(-7x - 5) - (-9x^2 + 8x + 7)
To simplify it, we just perform the difference between the polynomials:
-7x - 5 + 9x^2 - 8x - 7
Now we group terms with correspondent powers of x:
9x^2 + (-7x - 8x) + (-5 - 7)
Now we simplify this:
9x^2 - 15x - 12
This is the quadratic equation simplified.

find the angle y to the nearest degree:
cos y° = (7/19)
If anyone could also explain how, that would be great.
Answer:
y=68.38172757
Step-by-step explanation:
Take the inverse cosine of both sides of the equation to extract
y from inside the cosine.
y=arccos(7/19)
y=68.38172757
The cosine function is positive in the first and fourth quadrants. To find the second solution, subtract the reference angle from
360 to find the solution in the fourth quadrant. y=360−68.38172757
y=68.38172757+360n,291.61827242+360n, for any integer n

What is the inverse of the function g(x)=x^3/8+16?
The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
What is inverse of the function?"The inverse function of a function f (also called the inverse of f ) is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by [tex]f^{-1}[/tex]."
We have
[tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex]
Replace g(x) with y
[tex]y =[/tex] [tex]\frac{x^{3} }{8}+16[/tex]
Interchange the variables
[tex]x= \frac{y^{3} }{8}+16[/tex]
Rewrite the equation as
[tex]\frac{y^{3} }{8}+16= x[/tex]
⇒[tex]\frac{y^{3} }{8}= x-16[/tex]
Multiply both sides of the equation by 8
[tex]8.\frac{y^{3} }{8}=8(x-16)[/tex]
⇒[tex]{y^{3} }=8(x-16)[/tex]
⇒[tex]{y^{3} }=8x-128[/tex]
⇒[tex]{y} }=\sqrt[3]{8x-128}[/tex]
⇒[tex]{y} }=2\sqrt[3]{x-6}[/tex]
Replace y with [tex]g^{-1}(x)[/tex]
⇒[tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]
Hence, The inverse of the function for [tex]g^{}(x) = \frac{x^{3} }{8}+16[/tex] is [tex]g^{-1}(x)=2\sqrt[3]{x-6}[/tex]

Subtract area of triangle from total area: 30 - 14 = 16Since the figure is a square, all the sides are equal. Therefore, we need to find the square root of 16: √16 = 4All the sides of the square are 4 cm longTo check, reverse application:4 x 4 = 1616 + 14 = 30Alan and Margot each drive from City A to City B, a distance of 147 miles. They take the same route and drive at constant speeds. Alan begins driving at 1:40 p.m. and arrives at City B at 4:15 p.m. Margot’s trip from City A to City B can be described with the equation y = 64x, where y is the distance traveled in miles and x is the time in minutes spent traveling. Who gets from City A to City B faster?
Answer:
Margot gets from A to B faster

Alan takes 2 hr and 35 min = 2. 58... hr
Margot takes 147/64 hr = 2.296.. hr
A rectangular deck is 9 meters long by 7 meters wide. What is the length someone would walk
if they started at a corner and walked diagonally to the other corner?
Answer:
11.4 metres
Step-by-step explanation:
Use Pythagoras theorem for a right-angled triangle
a^2 + b^2 = c^2
if you cut the rectangle in half, it will become a right angled triangle.
a and b are two sides of the rectangle, while c is the diagonal or hypothenuse
so 9^2 + 7^2 = c^2
81 + 49 = c^2
c^ 2 = 130
square root 130 = c
you should get approximately 11.4 metres

A clothing store conducts a survey to determine customer satisfaction.
Which of these methods will produce the most representative sample of the population of store customers?
A. Survey all customers as they arrive at the store on a Monday.
B. Survey all customers who purchase shoes
C. Survey every 10th customer to enter the store.
D. Survey all customers who leave the store without making a purchase
Answer:
C
Step-by-step explanation:
This method is the best because it will survey the customers under one condition : every 10. If the store gets a lot of customers, then this should be easier to do. The rest are mostly dependent on what they do and that influences the survey. However, C makes it so that every 10 people are surveyed.
Answer:
A isnt the correct answer. B doesnt seem reasonable because its one specific item. D means they arent exactly a customer since they didnt buy anything therefore the answer would be C
C is your answer.

Karen and Ricardo are 279 miles apart driving towards each on the same route. Karen drives at a speed of 59 miles per hour and Ricardo drives at a speed of 65 miles per hour. In how many hours will they meet?
Answer:
They will meet in 2.25 hours or 2 hours 15 minutes
Step-by-step explanation:
At any point in time;
distance = speed * time
Let the number of hours at which they meet be x
In x hours, the distance traveled by Karen will be 59 * x = 59x miles
In same x hours, the distance traveled by Ricardo will be 65 * x = 65x miles
Since they are traveling in opposite directions, the distance traveled at that time by Karen will be less than what Ricardo has traveled since he is traveling at a greater speed
However, the sum of whatever they have traveled will be equal to the distance between them
thus;
59x + 65x = 279
124x = 279
x = 279/124
x = 2.25 hours
Card was bought for 5 dollars. It's has appreciated 5% each year. When will the card be worth 25 dollars?
Answer:
32 years
Step-by-step explanation:
Given data
Principal= $5
Rate= 5%
FInal amount= $25
Time=???
Applying the compound interest formula for time
t= ln(A/P)/r
t= ln(25/5)/0.05
t= ln(5)/0.05
t= 1.60/0.05
t= 35 years
Hence the time is 32 years

What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
We have,

OD. y= cos(2x)
(Ignore the answer selected I don’t know it it’s correct)
Using translation concepts, the function whose graph is plotted is given by:
y = 0.5cos(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
In this problem, the y-intercept is different of zero, hence it is a cosine function. The amplitude is of 0.5, hence the function is multiplied by 0.5, that is, y = 0.5cos(x), which means that option C is correct.
