Answer:
Proving a trigonometric identity refers to showing that the identity is always true, no matter what value of x x x or θ \theta θ is used. Because it has to hold true for all values of x x x, we cannot simply substitute in a few values of x x x to "show" that they are equal.

9. Which point of view is most likely to be uni eliable in a story?
All points of view in a story are equally eliable.
The first person narrator is most likely to be unreliable.
All points of view in a story are equally unreliable.
The third person point of view is most likely to be unreliable.
This question includes some misspelled words; here is the correct question:
Which point of view is most likely to be unreliable in a story?
All points of view in a story are equally reliable.
The first person narrator is most likely to be unreliable.
All points of view in a story are equally unreliable.
The third-person point of view is most likely to be unreliable.
The correct answer is The first-person narrator is most likely to be unreliable.
Explanation:
In a narrative text, an unreliable narrator implies the narrator lies on purpose to the reader, or his/her version of the story is not completely accurate. This feature of narration occurs mainly if the story, novel, etc. includes a first-person narrator. This is because in a first-person narrator, the thoughts, feelings, and point of view of one of the characters prevail, and this causes the events told are subjective and therefore more likely to be inaccurate. Also, this does not occur if there is a third-person narrator because in this case the narrator acts as an observer and this makes it more objective.
how to find the sale price of an item that has been discounted 25%
Answer:
Multiply the normal price of the item by .25 and then subtract that from the normal price.
Step-by-step explanation
[tex]x -(x*.25)[/tex]
x is the item
Step-by-step explanation:
100%-25%= discounted price= 75%
You do the discounted price divided by 75 to find 1%
do that times 100 to find the pre-discounted price.
e.g
find the original price of a sweater when it was on sale of 25%. the sale price is £15.00.
£15.00 = 75%
15.00 divided by 75 = 1% =£0.20
£0.20 x 100 = pre-sale price = £20.00
The price of the sweater before the sale is £20.00.

4(2x−9)=4 solve for x
Answer: x=5
Step-by-step explanation:
Distribute the 4 to the 2 and 9 and you will get (8x-36)=4.
Then you'd add the 36 to 4 to get 40.
Lastly you'd divide 8 and 40 to get 5. Hope this helps!!!

CAN SOMEONE PLEASE HELP WILL GIVE BRAINLIEST
Answer:
c = 7
d = 5
Step-by-step explanation:
Notice that in the first expression, x^c is inside a square root, and only perfect squares can be extracted from it. On the simplified form shown on the right hand side, we have x^3 outside the root and a single "x" left inside. In order for such to happen (x^3 get outside the root) there must have been an x^6 inside the square root. This together with the sole "x" that was left in the root, totals seven factors of x that should have been originally inside the square root:
x^6 * x = x^7 therefore c was a "7"
In the second expression we have a CUBIC root, so only perfect cubes can get extracted from it. Since there is one factor "x" shown in the simplified form (right hand side of the equal sign), that means that it must have been an x^3 (perfect cube) apart from the x^2 that was left inside the root. This makes the original power of x to be a 3 + 2 = 5.
Therefore d = 5
Describe the steps you would use to solve the equation 5( 2a - 3 ) = 20 + a.

Answer:
y=5.79x
Step-by-step explanation:
What you'll first do it divide both sides by y
So, y/y =5.79x/y
so the answer for question 1 is going to be 5.79xy.
If this is from the textbook, use slader. it might help you better than me.

A line passes through the point (8,4) and has a slope of -3/4 Write an equation in slope-intercept form for this line.
Step-by-step explanation:
Hey there!
Given;
The line passed through point (8,4) and made slope (-3/4).
Note: Use one-point formula.
[tex](y - y1) = m(x - x1)[/tex]
Put all values.
[tex](y - 4) = \frac{ - 3}{4} (x - 8)[/tex]
[tex]y - 4 = - \frac{3}{4} x - \frac{3}{4} \times - 8[/tex]
[tex]y - 4 = - \frac{3}{4} x + 6[/tex]
[tex]y = - \frac{3}{4} x + 6 + 4[/tex]
Therefore, the equation is: y = -3/4x +10.

3. Two glasses hold 12 ice cubes. How many ice cubes will 12 giasses hold?
Answer:
72.
Step-by-step explanation:
Two glasses hold 12 ice cubes. How many ice cubes will 12 glasses hold?
If 2 glasses hold 12, one glass holds 6.
If you are finding out how many ice cubes 12 glasses hold, you use the unit (6) and multiply it by 12. The answer is 72.
Hope I helped! Please mark Brainliest!
Answer:
72
Step-by-step explanation:
If two glasses can hold 12 ice cubes, half of 12 is 6 therefore it is 6 x 12= 72. 12 glasses will hold 72 ice cubes.
Hopefully this helps!
How to tell if your table is linear or exponential?
Answer: If the first difference is the same value, the model will be linear. If the second difference is the same value, the model will be quadratic. If the number of times the difference has been taken before finding repeated values exceeds five, the model may be exponential or some other special equation.
Step-by-step explanation: You can tell if a table is linear by looking at how X and Y change. If, as X increases by 1, Y increases by a constant rate, then a table is linear. You can find the constant rate by finding the first difference. This table is linear.

A sporting good store sells basketballs and footballs. Gavin pay $44 dollars for 3 basketballs and 2 footballs. Andrew pays $31 dollars for 1 basketball and 3 footballs. What is the price of 1 football
Answer: The price of 1 football = $ 7 and price of 1 basket ball= $10
Step-by-step explanation:
Let x = price of 1 football.
y = price of 1 basketball.
As per given,
[tex]3x+2y=44\ \ \ (i)[/tex]
[tex]x+3y=31\ \ \ \ (ii)[/tex]
Multiply 3 to (ii) , we get
[tex]3x+9y=93\ \ \ \ (iii)[/tex]
Eliminate (i) from (iii)
[tex]7y=49\\\\\Rightarrow\ y=7[/tex]
Put this in (ii), we get
[tex]x+3(7)=31\\\\\Rightarrow\ x+21=31\\\\\Rightarrow\ x=31-21=10\\\\\Rightarrow\ x=10[/tex]
Hence, the price of 1 football = $ 7 and price of 1 basket ball= $10
Julie sent 200 emails last month. This month she sent 40% less. How many
emails did she send this month?
Answer:
She sent 120 emails this month.
Step-by-step explanation:
Multiply 200 by .60 (60 percent) and it will give you 120.
I used 60 instead of 40 because the problem said 40 percent less, NOT 40 percent of 200.
