Answer:
-10
Step-by-step explanation:
Answer:
1. 5.4
2. The additive inverse is the negative value, -10.
The multiplicative inverse (reciprocal) is 1/10.
Step-by-step explanation:
1. Since the value within the absolute value is not negative then the value remains the same.
2, The opposite of positive 10 could be -10. The reciprocal is 1/10.

how do you write 8.4 in scientific notations
Answer:
To write as a scientific notation in this problem, just make something 0.0 x 10n
In this case, this is 8.9. Then, think about how many 10s have to be multiplied to make 8900.
It's three!
Move the decimal point left to 3 places to make 5.78. Then, n is the number of decimal places you moved:3
Same goes to the case 0.034. You need to make something 0.0 x 10n
Hence, move the decimal point right to 2 places to make 3.4. How many decimal places did you move?Two!
But because you went right to make it from 0.034 to 3.4, n becomes -2(the number got 100 times smaller).
Just don't forget to add that negative sign after you have solved a problem involving a number smaller than 1.

Answer:x=19 degrees
Step-by-step explanation:
Answer:
x = 19
Step-by-step explanation:
[tex]m\widehat{ XPZ} = 271\degree... (given) \\\\
m\widehat {XZ} =360\degree - 271\degree\\\\
m\widehat {XZ} =89\degree\\\\
m\angle XYZ = \frac{1}{2} \times (m\widehat{ XPZ} -m\widehat {XZ} ) \\\\
(4x +15)\degree = \frac{1}{2} \times(271\degree - 89\degree) \\\\
(4x +15)\degree = \frac{1}{2} \times 182\degree\\\\
(4x +15)\degree = 91\degree\\\\
4x + 15= 91\\\\
4x = 91-15\\\\

What is the vertex of the parabola: y=2(x-3)2^+4
Answer:
Vertex: (3,4)
Step-by-step explanation:
Vertex form of the quadratic equation
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The parabola is given as:
[tex]y=2(x-3)^2+4[/tex]
Comparing with the equation:
a=2, Vertex: (3,4)
The graph of the parabola is shown in the image below
Explain why 49 has two possible square roots
Answer:
Every positive number has 2 square roots, one positive and another one is negative. Square root of 49 is ±7, because you can obtain 49 by multiplying two 7's or two (-7)'s.
Step-by-step explanation:
Answer:
49 has 2 possible square roots +7 and -7
Step-by-step explanation:
49 has 2 possible square roots because 7x7=49
And -7 x -7 = 49
A negative times a negative equals a positive, so when you take the square root of 49, it is impossible to tell if 49 was the result of -7 x -7 or +7 x +7. Therefore, the square root of 49 has two possible answers.
-3x-8/4=10
What’s is value of x
Answer:
x= -16
Step-by-step explanation:
-3x-8/ 4 = 10
Here we can try to isolate x and so we have to first multiply 4 on each side.
-3x-8= 40
Then we can add the 8 to each side.
-3x= 48
Next, divide the -3 onto each side and we can get the answer!
x= -16

Use the number line. Enter the integer value that point D represents.
Number line from -10 to 10 with 20 tick marks. Point D is 1 tick mark to the left of 5.
Given:
A number line from -10 to 10 with 20 tick marks.
Point D is 1 tick mark to the left of 5.
To find:
The integer value that represents point D.
Solution:
A number line from -10 to 10 with 20 tick marks. It means, each mark represents the integer values from -10 to 10.
We know that, as we move towards left on a number line the value decreases and as we move towards right the value increases.
Point D is 1 tick mark to the left of 5. It means, point D represents the integer value which is 1 less than 5.
[tex]5-1=4[/tex]
Therefore, point D represents the integer 4.

Lucia draws a square and plots the center of the square, She claims that any rotation about
the center of the square that is a multiple of 45° will carry the square onto itself
Which statement best describes Lucia's claim?
A. Lucia's claim is correct since any rotation that carries a square onto itself is a multiple of 45°,
B. Lucia's claim is correct since any rotation that is a multiple of 45° carries a square onto itself
C. Lucia's claim is incorrect since not all rotations that carry a square onto itself are multiples of 45,
D. Lucia's claim is incorrect since not all rotations that are multiples of 45° carry a square onto itself
Answer:
The 2 si right
Step-by-step explanation:
We want to study the symmetry of a square and which rotations carry the square into itself.
We will see that the correct option is the last one:
Not all rotations of multiples of 45° carry the square into itself.
Here we have the claim:
" any rotation about the center of the square that is a multiple of 45° will carry the square onto itself"
And we want to see if this is true or not.
What we can try to do, is find a counterexample to see if this is false.
Let's draw a square, then make a point in the center of it, and draw a segment between the center and the right side.
Now rotate that segment around the center of the square (and along with it, the whole square) by 45°.
(note that 45° is a multiple of 45°).
Doing this, you will see that this rotation does not rotate the square into itself.
So the correct option is D, not all rotations of 45° rotate the square into itself. While rotations of 90°, 180°, 270°, etc... will map the square into itself, we just found an example of a rotation of a multiple of 45° that does not do it.
An image of the rotation can be seen below:

A square plot of land will be fully used for a square swimming pool with a 5 foot wide walkway around it. The area of the entire plot, including the walkway, is A square feet. Which expression gives the length of the pool?
Answer:
The expression that gives the length of the pool is [tex]\sqrt{A}[/tex] - 5
Step-by-step explanation:
Assume that the length of the pool is x feet
∵ The length of the pool is x feet
∵ The wide of the walkway around the pool is 5 feet
∴ The total length of the pool with the walkway = (x + 5) feet
∵ The area of the entire plot, including the walkway, is A square feet
∴ The area of the entire plot, including the walkway = A feet²
∵ The area of the square = (length)²
→ Substitute the length by (x + 5)
∴ The area of the entire plot, including the walkway = (x + 5)² feet²
→ Equate it by A
∴ A = (x + 5)²
→ To find x take square root for both sides
∵ [tex]\sqrt{A}[/tex] = [tex]\sqrt{(x+5)^{2}}[/tex]
→ Cancel the square root of the right side by power 2
∴ [tex]\sqrt{A}[/tex] = x + 5
→ Subtract 5 from both sides
∵ [tex]\sqrt{A}[/tex] - 5 = x + 5 - 5
∴ [tex]\sqrt{A}[/tex] - 5 = x
→ x represents the length of the pool
∴ The length of the pool is [tex]\sqrt{A}[/tex] - 5 feet
∴ The expression that gives the length of the pool is [tex]\sqrt{A}[/tex] - 5
The length of the pool will be √A-10.
What is area?Area is defined as the total space taken up by a flat surface or shape of an object.
Given that, A square plot of land will be fully used for a square swimming pool with a 5-foot wide walkway around it. The area of the entire plot, including the walkway, is A square foot.
The area of a square is side².
Let the side of the walkway be (x+10)
A = (x+10)²
√A = x+10
x = √A-10
Hence, The length of the pool will be √A-10.

Determine the equation of the line that passes through the given points. (3,18) and (8,33)
Answer:
[tex]y=3x+9[/tex]
Step-by-step explanation:
We want to determine the equation of the line that passes through the points (3, 18) and (8, 33).
First, let’s determine the slope. We can use the slope formula:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will let (3, 18) be (x₁, y₁) and (8, 33) be (x₂, y₂). Then it follows that:
[tex]\begin{aligned} m&=\frac{33-18}{8-3} \\ m&=\frac{15}{3} \\ m&=3\end{aligned}[/tex]
Hence, the slope is 3.
Now, we can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
We will substitute 3. for m. We can use either of the two points for (x₁, y₁) but let’s let (3, 18) be (x₁, y₁) for consistency. Thus:
[tex]y-18=3(x-3)[/tex]
Then it follows that:
[tex]\begin{aligned} y-18&=3x-9 \\ y&=3x+9 \end{aligned}[/tex]
Therefore, our equation is:
[tex]y=3x+9[/tex]

Ram has three times as many Rupees to coins as he has rupees 5 coins if he has in all a sum of rupees 77 how many coins of Rupee 2 does he have
9514 1404 393
Answer:
21 coins of ₹2
Step-by-step explanation:
Let x represent the number of ₹2 coins, and y the number of ₹5 coins. Then the total value of the coins is ...
2x +5y = 77
and the relationship between numbers of coins is ...
x = 3y
Substituting for x, we have ...
2(3y) +5y = 77
y = 77/11 = 7 . . . . simplify, divide by the coefficient of y
x = 3(7) = 21 . . . . find x from the second equation
Ram has 21 of the ₹2 coins.
