Find f (-8) and f (6) for the given function.
f (-x) = (x -1)
To find f(-8) and f(6), all that we need to do is plug in each of the numbers for x.
f(-8) = -8 - 1 = -9
f(-8) = -9
f(6) = 6 - 1 = 5
f(6) = 5
Hope this helps!
If f(-x) = x - 1, then f(x) = - x - 1. So
f(-8) = 8 - 1 = 7
and
f(6) = - 6 - 1 = -7
Find the unknown length of the side labeled x.
When we are given sides and an angle, and a right triangle (seemingly), the easiest method of solving is using trigonometry.
Remember: SOH-CAH-TOA
Looking from the given angle, we are given the opposite side and want to know the hypotenuse. Therefore, we should use the sin function.
sin(34) = 2 / x
(x)(sin(34)) = 2
x = 2 / sin(34)
x = 3.7801
x = 3.7801

Use completing the square to solve for x in the equation (x-12)(x+4)= 9.
Answer:
x=4+√73 or x=4−√73
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x^2−8x−48=9
Step 2: Add 48 to both sides.
x^2−8x−48+48=9+48
x^2−8x=57
Step 3: The coefficient of -8x is -8. Let b=-8. Then we need to add (b/2)^2=16 to both sides to complete the square.
Add 16 to both sides.
x^2−8x+16=57+16
x^2−8x+16=73
Step 4: Factor left side.
(x−4)^2=73
Step 5: Take the square root.
x−4=±√73
Step 6: Add 4 to both sides.
x−4+4=4±√73
x=4±√73
x=4+√73 or x=4−√73
Answer:
x=4+√73 or x=4−√73

Given that cos 63°≈ 0.454, enter the sine of a complementary angle.
sin
Answer:
[tex]\cos(63^\circ)[/tex] is the same as [tex]\sin(27^\circ)[/tex] by co-function identities
Step-by-step explanation:
Remember that complementary angles add up to 90°. The angle that i s complementary to 63° is 27°.
Also recall the co-function identities:
sin (90° – x) = cos xcos (90° – x) = sin xThis means that [tex]\cos(90^\circ-27^\circ)=\sin(27^\circ)\approx0.454[/tex].
Suppose a jar contains 11 dimes, 21 nickels, and 12 pennies. Barbie selects a coin and puts it back in the jar and then Darren selects a coin from the jar. Is this a set of independent or dependent events?
Answer:
Independent
Step-by-step explanation:
Barbie selecting a coin and putting it back in has no effect on Darren selecting a coin from the jar, as the numbers of each coin never changed. So, both events are independent with neither relying on the other.
Simplify the following:
a. a+a+a+a+a+a
b. 5x-4x+10x
c. 9t+3t-6t
d. -5j+11j+j
=(a+a+a+a+a+a)
= 6a
b. 5x-4x+10x=(5x+−4x+10x)
= 11x
c. 9t+3t-6t=(9t+3t+−6t)
= 6t
d. -5j+11j+j=(−5j+11j+j)
= 7j
a)= 6a
b)= 11x
c)=6t
d)= 7j

2. If x = -8, which inequality is true?
A. -3x - 2 = 24
B. 12 + 2x > 9
C. 4x -19 318
D. 17 + x>10
Answer:
[C] 4x - 19 < 318
Step-by-step explanation:
For [C] I think you meant: [C] 4x - 19 < 318
Since, x = -8
then we can plug it in to each answer choice to find the answer:
[A] -3x - 2 = 24
⇒ -3(-8) - 2 = 24
-3(-8) = 24
24 -2 = 22 not 24
False.
[B] 12 + 2x > 9
⇒ 12 + 2(-8) > 9
12 -16 > 9
-4 > 9
False.
[C] 4x -19 < 318
⇒ 4(-8) -19= 318
-51 < 318
True.
[D] 17 + x>10
⇒ 17 + (-8) >10
-25 > 10
False.
Hence, the answer is [C] 4x - 19 < 318

Hannah and Anthony are siblings who have ages that are consecutive odd integers. The sum of their
ages is 92. Which equations could be used to find Hannah's age, h, if she is the older sibling?
Answer:
2h+92
Step-by-step explanation:
The equation that will represent the sum of the age of Hannah and Anthony will be 2h+2=92.
Let the age of Hannah be x. and Since the age of Hannah and Anthony are two consecutive odd integers, therefore, the age of Anthony will be (h+2).
As it is given that the sum of the ages of the two other person is 92, therefore, the equation that will represent the sum of the age of the two persons can be written as, 2h+2=92
Thus, the equation that will represent the sum of the age of Hannah and Anthony will be 2h+2=92.

The following shape has 1 pair of parallel sides. What is the area of the shape?
Step-by-step explanation:
Area of triangle on L = 1/2 b * h = 1/2 * 8 * 8 = 32 units^2
Area of triangle on R = 1/2 b*h = 1/2 * 6 *5 = 15 uits^2
Area of rectangle in between = width x height = 2x 5 = 10 units^2
Total area = 32 +15 +10 = 57 units^2
On the same coordinate plane mark all points (x,y) such that
(A) y=x+3
(B) y=-x+3
(C) y=|x|+3
The graphs of the 3 given functions can be seen in the image attached at the end.
How to mark all the wanted points?
Here we basically want to graph the next 3 functions:
y = x + 3
y = -x + 3
y = |x| + 3
So, the first two are linear equations. To graph these we just need to find two points on the line and connect them with a line.
The last one is the absolute value function translated up by 3 units.
So, to give an example of how to graph the first equation, first we evalaute in x = 0, then we get:
y = 0 + 3 = 3
So we have the point (0, 3)
For that same line we can evaluate in x = 1
y = 1 + 3 = 4
Then we also have the point (1, 4).
Now we have 2 points, we can just connect them with a line.
The graph of the 3 equations can be seen below.
A is the blue line, B is the red line, C is the orange graph.

PLEASE ANSWER BOTH QUESTIONS DUE TODAY!!!! (19 POINTS)
Answer:
A) 8,500
B) B, C
Step-by-step explanation:
A) This seems to be a conversion problem. Since she runs 3 km every Monday Wednesday, and Friday, she would be running 6 km in total every week EXCLUDING the 2,500 meters. Since the question asks how many meters Kailee runs, you would need to convert 6 km to m and add the result to 2,500 meters. To convert km to m you just need to divide the value by 1000 (if your teacher asks for the full conversion method its 6 km * 1 m/1000 km or [tex]6 km * \frac{1m}{1000 km}[/tex]), so 6 km is 6,000 meters. Adding 6,000 to the left over 2,500 from Saturday, the final answer will be 8,500.

PLS HELP!.... a garden has more daisies than roses, and there is at least one rose. Let r represent the number of roses and let d represent the number of daisies. Let's compare the expressions 3r and r + d. Which statement is correct? Choose 1 answer:
A 3r>r + d
B 3r
C 3r=r + d
D There is not enough information to tell.
Answer:
Step-by-step explanation:
since d > r , becasue more daises, than roses, we know that the answer must also reflect this logic.
A is 3r > r+d , can't be true, b/c with one rose, the amount of roses + daises would be 3, and then 3r = r+d so A is wrong
B is 3r ??? we don't have an equation or inequality to solve.
C 3r = r+d, this could be true if r=1 and d=2 and would also be correct for all the requirements. C seems true,
D Also, for the teacher that wrote this, " compare expressions" means there are zero equal signs , expressions are with out equal signs, equations have them, as does C :/ This teacher doesn't know what they are talking about. >:/
Based on the equation, the correct answer is D. There is not enough information to tell.
How to explain the equationThe statement "a garden has more daisies than roses, and there is at least one rose" implies that the number of daisies (d) is greater than the number of roses (r), but it does not provide any specific values for r and d.
Without knowing the specific values of r and d, we cannot determine whether 3r is greater than, equal to, or less than r + d. Therefore, the correct answer is D, indicating that there is not enough information to determine the relationship between 3r and r + d.
