Squareroot of 9 is equal to
Answer:
√9 = ±3
Step-by-step explanation:
... Because 3 × 3 = 9 and (-3) × (-3) = 9
However, it is agreed universally that we take the so-called “positive square root”. That is, we accept that the only answer is 3. In contrast, when we have (x^2) =9, where x is a variable, we don't know whether x is positive or negative so we cannot rule out the possibility that x is negative.
Square root means a number that produces a specified quantity when multiplied by itself.
Answer:
± 3
Step-by-step explanation:
[tex]\sqrt{9}[/tex] = ± 3
That is + 3 or - 3
Since 3 × 3 = 9 and - 3 × - 3 = 9

A positive number times a negative number = negative number. Now you
need to locate the decimal point in the first number 1 digit after the decimal and in the second number first digit after the decimal. So in your answer from right to left count two places and the decimal will be located between the 4 and 8.
The Barrick family is going to Red Rock Canyon for a family reunion. They thought it would be cool to have shirts made for the event. The Sensational Shirts quoted them a price of $5 per shirt plus one-time processing fee of $8.50. Write an algebraic expression to represent the total cost of the shirts. How much would 17 shirts shirts cost? If they divide the total cost evenly how much will they pay each shirt?

The table shows the height of a plant as it grows.
a. Model the data with an equation.
b. Based on your model, predict the height of the plant at 12 months.
A. y - 9= 3/2(x - 3); 18cm
B. y – 9 = 3(x – 3); 36 cm
C. The relationship cannot be modeled.
D. y - 3= 3/2(x - 9); 39cm
Answer:
B. y – 9 = 3(x – 3); 36 cm
Step-by-step explanation:
Answer:
The equation which represents the given data is and the height of the plant at 12 months is 36 cm.
Step-by-step explanation:
Given :
Time (months)(x): 3, 5, 7, 9.
Plant height (cm)(y), 9, 15, 21, 27.
Solution:
We will use two point slope form to find the equation which represents the given situation.
Formula:
Substitute the values in the given formula.
Now we are supposed to find the height after 12 months.
So, the equation which represents the given data is and the height of the plant at 12 months is 36 cm.
Thus Option B is correct.
4x/5 - 3x/7 = 4x/7 + 5x/7 can anyone please help with explanation...
Answer: x=0
Step-by-step explanation:
Multiply both sides of the equation by 35, the least common multiple of 5,7.
7×4x−5×3x=5×4x+5×5x
Multiply 7 and 4 to get 28.
28x−5×3x=5×4x+5×5x
Multiply −5 and 3 to get −15.
28x−15x=5×4x+5×5x
Combine 28x and −15x to get 13x.
13x=20x+25x
Combine 20x and 25x to get 45x.
13x=45x
Subtract 45x from both sides
13x−45x=0
Combine 13x and −45x to get −32x
−32x=0
Product of two numbers is equal to 0 if at least one of them is 0. Since −32 is not equal to 0, x must be equal to 0.

Find the emoji with a diameter of 12 cm. Draw the emoji here. Find the area and circumference of the emoji. Area Circumference: А = ar2 C = πd
Step-by-step explanation:
First
diameter 9in = the emoji below 5in ( celebration emoji)
A = 63.64in².
C= 9π in
.
Second
diameter 12cm= loving emoji (left side of celebration emoji)
A=36π cm²
C= 12π cm.
if possible use 22/7 instead of π .
hope this helps you.
A number is chosen at random from the integers 10 to 30 inclusive. Find the probability that the number is a multiple of 3.
Answer:
For each part, find how many numbers have the stated characteristic, then divide by 21.
e.g. multiples of 5:
these would be 10, 15, 20, 25, and 30
so prob (a multiple of 5 ) = 5/21
Do the others the same way

The difference of two numbers is 16. The greater number is 5 less than 4 times the smaller number. Find the product of the two numbers.
Answer: y = 23
Step-by-step explanation:
let x = smaller number
let y = greater number
y = 4x - 5
y - x = 16
replace the value of y in the second equation you get
4x -5 -x = 16 ⇒ 3x - 5 = 16 ⇒ 3x = 21 ⇒ x = 7
finally,
y = 23

Express equation 6x - 4y = 12 in the form of y=mx + c
Answer:
y = 3/2x - 3, where m is 3/2 and c is -3
Step-by-step explanation:
First, we add 4y on both sides of the original equation. Then, we get
6x = 12 + 4y. Next, we subtract 12 on both sides to get 4y = 6x - 12. We finally divide by 4 to get y = 3/2x - 3
Help me solve this equation
Answer:
a = n/5 + 3h^2
step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
a = n/5 + 3h^2
Answer:
n+15 to the power of 2=a
Step-by-step explanation:
1.multiply 5 by and and -3h to the power of 2
2. subtract 15h to the power of 2 from both sides
3. divide by 5 on each side

Answer:
Step-by-step explanation:
400
is the answer
◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ ◦ [tex]Hello! :)[/tex]
16+24=-4(9x-10)
Use the Distributive property first:
16+24=-36x+40
Make sure that x's and other variables are on the left side of the equation. Remember to use the opposite operation!
36x-40=-16-24
Now, make sure all the numbers are on the right side of the equation:
36x=40-16-24
36x=0
x=0
All the best!

Step-by-step explanation:
(- 3) - 2y = - 6- 2y = - 3
[tex]y = \frac{ - 3}{ - 2} [/tex]
[tex]y = \frac{3}{2} [/tex]
(- 2) - 2y = - 6- 2y = - 4
y = 2
0 - 2y = - 6- 2y = - 6
y = 3
7(-3) + 2y = - 10- 21 +2y = - 10
2y = 11
[tex]y = \frac{11}{2} [/tex]
7(-2) + 2y = - 10- 14 + 2y = - 10
2y = 4
y = 2
7(0) + 2y = - 102y = - 10
y = - 5
