How does -1.125 + 1.2 = 0.075 instead of 0.925?
Answer:
.0075 (hope this help; let me know if not)
Step-by-step explanation:
The operation is + and the signs of the numbers are opposite so we have to subtract. The bigger number has positive sign in front if so we do 1.2-1.125=1.200-1.125
I'm going to line up
1.200
-1.125
---------
If you have 200 and you take about 125... 75 should beleft
so

20 Points! if pencils cost $2.40 for twelve, what is the unit price per pencil?
Answer:
$0.20
Step-by-step explanation:
A dozen of pencils = $2.40
1 pencil = $2.40 ÷ 12 = $0.20
PLEASE DO MARK ME AS BRAINLIEST UWU
ALSO, DO HAVE A GREAT DAY ;)
The unit price per pencil is determined by dividing the total cost of the pencils ($2.40) by the total number of pencils (12), giving a result of $0.20 per pencil.
Explanation:To find the unit price per pencil, you would divide the total cost by the total number of items.
In this case, the total cost is $2.40 and there are twelve pencils, so the calculation is $2.40 ÷ 12.
This will give you the unit price per pencil.
Using the numbers provided, $2.40 (the total cost) divided by 12 (the total number of pencils) equals $0.20.
So, the unit price of a pencil is $0.20.

Which set of coordinates, paired with (-3, -2) and (-5, -2), result in a square?
The set of coordinates which paired with (-3,-2) and (-5,-2) are (-4,0) and (-4,0).
What are coordinates?The coordinates are the points with the help of which we can draw any figure on the graph.
How to find coordinates?We know that all the sides of a square are equal to each other.
Let ABCD be a square.
Coordinates of A(-3,-3) and C be(-5,-2)
Let the coordinates of B and D be (x1,y1) and (x2,y2)

Final answer:
The coordinates that form a square when paired with (-3, -2) and (-5, -2) are (-3, 0) and (-5, 0). The sides of the square are 2 units long, and by moving perpendicularly up by 2 units from each given point, we find the other two vertices of the square.
Explanation:
The student has asked which set of coordinates, when paired with (-3, -2) and (-5, -2), would result in a square. To find the coordinates that complete the square, we need to consider that the diagonals of a square are equal in length and bisect each other at right angles. The two given points (-3, -2) and (-5, -2) form a side of the square that is parallel to the x-axis and 2 units long. Since a square has all sides equal, the other two vertices of the square will be 2 units away from these points but in a perpendicular direction.
Here's how we calculate it step by step:
First, we determine the length of the side of the square by calculating the distance between the points (-3, -2) and (-5, -2), which is 2 units.
Next, we move 2 units perpendicularly from each point which can be done by either keeping the x-coordinate constant and changing the y-coordinate or vice versa. Since we want to be perpendicular to the x-axis, we change the y-coordinate.
The change in the y-coordinate could be either upwards (+2) or downwards (-2). Considering the y-value of the given points, one possible set of coordinates for the other two vertices are (-3, 0) and (-5, 0).
Therefore, the coordinates (-3, 0) and (-5, 0), when paired with (-3, -2) and (-5, -2), form a square.

What is the radius of a circle whose equation is x2 + y2 + 8x – 6y + 21 = 0? units
Answer:
2
Step-by-step explanation:
Center: (−4,3)
Radius: 2
Answer:
radius = 2
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r the radius
Given
x² + y² + 8x - 6y + 21 = 0
Use the method of completing the square to obtain standard form
Collect the x- terms and y- terms together and subtract 21 from both sides
x² + 8x + y² - 6y = - 21
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(4)x + 16 + y² + 2(- 3)y + 9 = - 21 + 16 + 9
(x + 4)² + (y - 3)² = 4 ← in standard form

What’s the median of the data 24,2,13,12,2,5,10,18
Answer:
11
Step-by-step explanation:
arrange from smallest to greatest:
2,2,5,10,12,13,18,24
The median is the middle name.
If you have two middles, the median is the average of them.
So you have 2 middles, 10 and 12.
The average of 10 and 12 is given by (10+12)/2=11
Hello There!
The median is the middle number of the data set so let’s find it!
Step 1. Order your numbers from least to greatest so after we have done that, our numbers would be 2,2,5,10,12,13,18,24
Step 2. We want to cross of a number at the beginning so Starting with 2 and the last number 18 and do that either until we get to one number in the middle or two numbers.
Step 3. There is no one number in the middle but we have the numbers 10 and 12 so we add them together which gives us a sum of 22 and then divide 22 by 2 and we get a quotient of 11.
Our median is 11.

For which values of x does 2x^2=10x?
Answer:
x = 0; x = 5
Step-by-step explanation:
2x² = 10x
2x² - 10x = 0
2x(x - 5) = 0
x = 0; x = 5
Answer:
The values of x for which it is true that [tex]2x^2=10x[/tex] are:
[tex]x = 0[/tex] and [tex]x = 5[/tex]
Step-by-step explanation:
We have the following equation
[tex]2x^2=10x[/tex]
To solve the equation subtract 10x on both sides of the equation
[tex]2x^2-10x=10x-10x[/tex]
[tex]2x^2-10x=0[/tex]
Now take the variable x as a common factor
[tex]2x(x-5)=0[/tex]
Then the equation is equal to 0 when x = 0 or when x = 5
[tex]x = 0[/tex] and [tex]x = 5[/tex]

O A. x+4
O B. 9
0.0
D. X +5
Please help I’m stressed and I wanna cry MATH IS ANOTHER LANGUAGE TO ME
Answer: X+5
Step-by-step explanation:
When you take out the 9 it should be 9(x+5) and when you take out the 9x on the bottom it gives you (x+5)+20 therefore x+5 is your GCF.
I hope this helps :)
The greatest common factor (GCF) of the numerator 9x+45 and the denominator x^2 +9x+20 of the provided rational expression is x+5.
Explanation:The greatest common factor (GCF) is found by factoring both the numerator and the denominator and then identifying the largest factor that appears in both. For the provided rational expression 9x+45 over x2 +9x+20, let's factor both parts:
Numerator: 9x+45 can be factored out as 9(x+5).Denominator: x2 +9x+20 can be factored into (x+4)(x+5).Comparing both factored forms, we can see that x+5 appears in both the numerator and the denominator, and it is the largest factor common to both. Therefore, the GCF of the numerator and the denominator is x+5.
Please answer from the question above :)
Answer:

Step-by-step explanation:
The question simply asks us to plug in 45 minutes into the given equation. In the graph, we see that y-axis is defined to be time. Therefore we set y=45 and solve for x.
45=-6/5x+86
-41=-6/5x (subtract 86 from both sides)
-41*(-5)=-6/5x*(-5) (multiply both sides by -5)
205=6x (divide both sides by 6)

When solving for x, the sine of 44º is used. What other angle and trigonometric function could be used to solve for x? a. tan 46º c. tan 44º b. cos 46º d. cos 44º
Answer:
cos46°
Step-by-step explanation:
Using the co function identity
sin x° = cos(90 - x)°, hence
sin44° = cos(90 - 44)° = cos46°
Answer: The correct option is (b) cos 46°.
Step-by-step explanation: Given that when solving for x, the sine of 44º is used.
We are to select the other angle and trigonometric function that could be used to solve for x.
We know that,
the sine of any acute angle is equal to the cosine of its complement.
That is,
if y denotes the measure of any acute angle, then we have
[tex]\sin y=\cos(90^\circ-y).[/tex]
Therefore, if y = 44°, then we get
[tex]\sin 44^\circ=\cos(90^\circ-44^\circ)=\cos 46^\circ.[/tex]
Thus, the other angle and the trigonometric function that could be used to solve for x is cos 46°.
Option (b) is CORRECT.

if f(x)= 3x+6 which of the following is the inverse of f(x)
Answer:
f(x)^-1 = 1/3x - 2
Step-by-step explanation:
Replace f(x) with y and solve:
y = 3x + 6
Swap x and y
x = 3y + 6
Now isolate y
x/3 = 3y/3 + 6/3
1/3 x = y + 2
1/3 x - 2 = y + 2 - 2
y = 1/3x - 2 or f(x)^-1 = 1/3x - 2
For this case we have the following function:
[tex]f (x) = 3x + 6[/tex]
We must find the inverse of the function, then:
Replace f (x) with y:[tex]y = 3x + 6[/tex]
We exchange the variables:
[tex]x = 3y + 6[/tex]
We solve for "y":
Subtracting 6 on both sides of the equation:
[tex]x-6 = 3y[/tex]
Dividing between 3 on both sides of the equation:
[tex]y = \frac {x} {3} - \frac {6} {3}\\y = \frac {x} {3} -2[/tex]
We change y by [tex]f ^ {- 1} (x)[/tex], and finally we have:
[tex]f ^ {- 1} (x) = \frac {x} {3} -2[/tex]
ANswer:
[tex]f ^ {- 1} (x) = \frac {x} {3} -2[/tex]
