if f(x)=x-4 find the value if f(x)+f(-x)
Answer:
2x
Step-by-step explanation:
f(x) = x -4
Step 1:
y = x - 4
Step 2: Replace y with x
x = y - 4
Step 3: Find y
x + 4 = y
f(-x) = x + 4
f(x) + f(-x) = (x - 4)+ (x + 4) = 2x
1. How much interest
will Hannah earn in 4 years if she
deposits $630 in a savings account at
6.5% simple interest?
Answer:
$163.8 more.
Step-by-step explanation:
Let's use the formula Principle × Rate × Time, or PRT to find our simple interest. Let's fill in the blanks. Our principle is $630. Our rate is 6.5% and our time is 4 years. Next, we multiply all this. $630 × 13/200 × 4. Our answer would be 163.8. I hoped this helped.
We can calculate the volume V of a rectangular prism using V = lwh, where l is the length, w is the width, and h is the height of the
prism. Suppose that a prism has a volume of 200 cm and l = 2w.
a. Select all of the equations that rewrite the volume formula by making substitutions for V and l.
200 = 2w²h
200 = 4wh
V = 22
2w xwxh = 200
Answer:
Step-by-step explanation:
200=2w²h
The equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200
We have a prism and the formula to calculate its volume is given.
We have to select all of the equations that rewrite the volume formula by making substitutions for V = 200 cubic centimeter and L = 2w.
What is Prism ?A Prism is a three-dimensional shape, which consists of two identical polygons, which do not lie in the same axis.
According to the question, we have -
Volume of Prism = 200 cubic centimeter
L = 2w
The formula to calculate the volume of prism equals to -
V = Lwh
Substituting values, we get -
200 = 2[tex]w^{2}[/tex]h
or
2w x w x h = 200
Hence, the equations are -
200 = 2[tex]w^{2}[/tex]h
2w x w x h = 200

An experiment to determine how many breaths a squirrel takes per minute yields this data: minute 1: 65 breaths;minute 2: 73 breaths; minute 3: 67 breaths; minute 4: 71 breaths; minute 5: 62 breaths. Calculate the average number of breaths per minute.
The average number of breaths per minute would be 67.6 breaths per minute.
Average can be calculated by dividing the sum of the observation by the number of observations,
[tex]Average = \frac{sum of observations}{number of observation}[/tex]
Step by step Explanation:
Over the course of 5 minutes, the squirrel takes
65 + 73 + 67+ 71+ 62 = 338 breaths in 5 minutes
So, the sum of observation = 338 and
the number of observations = 5
So If you take that number and divide it by the number of minutes, you will get the average.
[tex]=\frac{338}{5}[/tex]
67.6 breaths per minute.
Thus, the correct answer is - 67.6 breaths per minute.

Amela put 15x- 4 gallons of gas in her car at the beginning of the week. She used 7x-3 gallons driving to work. Which of the following choices represents the
number of gallons left in her car?
A) 22x+7
B) 22x-7
C) 8x+1
D) 8x-1
Answer:
D) 8x - 1
Step-by-step explanation:
Let's say that x = 5. That would mean Amelia put 15(5) - 4 gallons of gas in her car, which equals 71 gallons. She used 7(5) - 3 gallons driving to work, which is 32 gallons used. 71 - 32 = 39 gallons left.

Kajal spoke on the phone from 4{:}50 \text { p.m.}4:50 p.m.4, colon, 50, start text, space, p, point, m, point, end text until 6{:}19 \text { p.m.}6:19 p.m.6, colon, 19, start text, space, p, point, m, point, end text
How long did Kajal speak on the phone?
Answer:
1 hour and 29 minutes
Step-by-step explanation:
4:50 pm to 6:00 pm is 1 hour and 10 minutes.
6:00 pm to 6:19 pm is 19 minutes.
1 hour and 10 minutes + 19 minutes = 1 hour and 29 minutes.
Explanation:
Let's find out how long Kajal spoke on the phone.
4:50 + 10 mins = 5:00
5:00 + 60 mins = 6:00
6:00 + 19 mins = 6:19
To find the total time between 4:50 + 6:19, we add the distances.
10 mins + 60 mins + 19 mins = 89 mins
Thus, Kajal spoke on the phone for 89 minutes.

Mary, Misa and Mandy have a combined height of 4.84 m. Mary is 9 cm/0.009m
shorter than Misa. Misa is 0.05 m taller than Mandy. How tall, in metres, is
Mandy?
Answer:
Mandy is 1.613 m tall
Step-by-step explanation:
Let us consider
Mary is A, Misa is B and Mandy is C
According to question,
A + B + C = 4.84 m...... (i)
From qsn
9 cm/0.009 m
= 9 cm/ 0.9 cm
= 10 cm
= 0.1 m
Then, A is 0.1 m shorter than B
i.e. A= B - 0.1 m
Also, B is 0.05 m taller than C
i.e B = C + 0.05m
We have to find height of C ( Mandy)
From eqn (i)
C = 4.84 - B - A
or, C = 4.84 - (C + 0.05) - ( B - 0.1)
or, C = 4.84 - C - 0.05 - B + 0.1
or, 2C = 4.89 - B
or, 2C = 4.89 - ( C + 0.05)
or, 2C = 4.89 - C - 0.05
or, 3C = 4.84
or, C = 4.84/3
or, C = 1.613 m
Find the distance between each pair of points (-4,6) and (3,-7)
Answer:
Here is your answer . Hope this helps you.
Answer:
[tex]\boxed {\boxed {\sf \sqrt{218} \ or \ 14.76}}[/tex]
Step-by-step explanation:
The formula for calculating the distance between 2 points is:
[tex]d= \sqrt{(x_2-x_1)^2 +(y_2-y_1)^2[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the 2 points. The 2 points we are given are (-4, 6) and (3, -7). If we match the value with the corresponding variable we see that:
x₁ = -4 y₁ = 6 x₂ = 3 y₂ = -7Substitute the values into the formula.
[tex]d= \sqrt{(3 - -4)^2 + (-7-6)^2[/tex]
Solve inside the parentheses.
(3--4) = (3+4) = 7 (-7-6) = -13[tex]d=\sqrt {(7)^2 + (-13)^2[/tex]
Solve the exponents.
(7)²= 7*7 = 49 (-13)² = -13 * -13 = 169[tex]d= \sqrt{ (49)+(169)[/tex]
Add.
[tex]d= \sqrt{218}[/tex]
[tex]d=14.76482306[/tex]
If we round to the nearest hundredth place, the 4 in the thousandth place tells us to leave the 6.
[tex]d \approx 14.76[/tex]
The distance between the points (-4, 6) and (3, -7) is √218 or approximately 14.76.
Evaluate the expression.

Aisha wants to paint the wall of the room. She knows that each can of the paint contain one gallon. A half gallon will completetly cover a 55 square feet of wall. Each of the four wall of the room is 10 feet high. Two of the walls are 10 feet wide and two of the walls are 15 ft wide. How many one gallons buckets of paint does aisha need to buyin order to paint the room ?
Answer:
It doesn't say what to do with that 0.1 of a gallon. I would buy another gallon or dilute what I had so it came to exactly 9.1 gallons. In math, I suppose the answer is 9.
In reality it would be 10.
You have to choose. What has been done with other questions like this.
Step-by-step explanation:
1 can covers 55 square feet.
h = 10
w1 = 10 feet
w2 = 10 feet
w3 = 15 feet
w4 = 15 feet
Total area = Area of wall 1 + wall 2 + wall 3 + wall 4
Total area = 10*10 + 10*10 + 10*15 + 10* 15
Total area = 100 + 100 + 150 + 150
Total area = 500 feet^2
1 gallon / 55 ft^2 = x / 500 ft^2 Cross multiply
55 * x = 500 Divide by 55
x = 500/55
x = 9.1 gallons.
In real life you would buy another gallon.

Explanation:
Let's say that the first 26 people will occupy each of the 26 rooms. This means that, so far, there's one person per room.
There are 40-26 = 14 people left. Let's say those 14 people occupy the first 14 rooms. This means that the first 14 rooms now have 2 people in them per room. The remaining 26-14 = 12 rooms still have one person per room.
