What is 3/5 by 1/2 reduced?
Answer: 1/10
Step-by-step explanation:
I think you mean 3/5 - 1/2?
we need to make the denominators the same, so we find the LCM of 5 and 2, which is 1, so we multiply them to get a common denominator of 10.
Now we multiply 3/5 by 2/2 to get 6/10, and 1/2 by 5/5 to get 5/10.
6/10 - 5/10 = 1/10

Step-by-step explanation:
f(x) = |3x+5| + 6
g(x) =7
find (f+g) (x)
Answer:
(f + g)(x) = |3x + 5| + 13
Step-by-step explanation:
Given
f(x) = |3x + 5| + 6
g(x) = 7
Required
Find (f + g)(x)
In functions
(f + g)(x) = f(x) + g(x)
Meaning that, we simply add the given functions together
So, we have that:
(f + g)(x) = |3x + 5| + 6 + 7
(f + g)(x) = |3x + 5| + 13
Hence, (f + g)(x) when calculated equals |3x + 5| + 13

Tracy found the length of GF. Her work is shown below.
Triangle A B C has centroid G. Lines are drawn from each point through the centroid to the midpoint of the opposite side to form line segments A E, B F, and C D. The length of line segment A G is 16, the length of line segment G E is 2 x, and the length of line segment B G is 8 x.
16 = 2(2x)
16 = 4x; x = 4
8(4) = 32
GF = 2(32)
GF = 64
What error did Tracy make?
She used AG = 2EG, but the correct statement is 2AG = GE.
She found that x = 4, but the correct value for x is 2.
She used GF = 2BG, but the correct statement is BG = 2GF.
She found that GF = 64, but the correct value of GF is 8.

Step-by-step explanation:
In Exercises 1-3, graph AABC and its image after a reflection in the given line.
1. A(0, 2), B(1, -3), C(2, 4); x-axis
1.
2. A(-2,-4), B(6,2), C(3. – 5); y-axis
3. A(4, -1), B(3, 8), C(-1, 1); y = -2
Answer:
1. Point A: (0, 2)
Point B: (-1, -3)
Point C: (-2, 4)
2. Point A: (-2, 4)
Point B: (6, -2)
Point C: (3, 5)
3. Point A: (4, -3)
Point B: (3, -12)
Point C: (-1, -5)
Step-by-step explanation:
1.
Reflection of point A:
Reflections over the x-axis are really easy. All you have to do is change the x-coordinate to the opposite sign.
In this case, 0 does not need to change since it already lies on the x-axis.
The coordinate for A will stay the same as (0, 2).
Reflection of point B:
Again, change the x-coordinate to negative.
1 → -1
The coordinate for B will now be (-1, -3).
Reflection of point C:
2 → -2
The coordinate for C will now be (-2, -4).
2.
Reflection of point A:
Reflections over the y-axis are also really easy. This time, all you have to do is change the y-coordinate to the opposite sign.
In this case, -4 would change to just 4.
The coordinate for A will stay the same as (2, 4).
Reflection of point B:
Again, change the y-coordinate to negative.
2 → -2
The coordinate for B will now be (6, -2).
Reflection of point C:
-5 → 5
The coordinate for C will now be (-1, 5).
3.
This is going to be a bit harder than the previous two, but I know you can handle it. :)
Reflection of point A:
The x will stay the same and only the y will change.
Take the y-coordinate and subtract it from the reflection line while getting the absolute value..
|(-1) - (-2)| = |1| = 1
This means, point A is one unit down the line y = -2
(-2) - 1 = -3
The coordinate for A will now be (4, -3).
Reflection of point B:
Again, the x will stay the same and only the y will change.
Using the absolute value, get the y-coordinate and subtract it from the reflection line again..
|(8) - (-2)| = |10| = 10
This means, point A is five unit down the line y = -2
(-2) - 10 = -17
The coordinate for B will now be (3, -12).
Reflection of point C:
I think you get the gist of it.
|(1) - (-2)| = |3| = 3
(-2) - 3 = -5
The coordinate for C will now be (-1, -5).
The red triangle is the original image and the blue triangle is the image after the reflection. The purple line is the reflection line.
Hope this helped!
The graph of Exercises 1-3 that shows AABC and its image after a reflection in the given line can be done using the example from the graph attached.
What is reflection about?A reflection over line is known to be a kind of transformation where each point of the main or original figure (that is the pre-image) is said to be made up of an image that has similar distance from the reflection line.
Note that In a reflection, the image is said to be of similar size and also of the same shape as the original image.
Therefore to be able to construct the graph of Exercises 1-3, one can use the image example by tracing the number values such as A(0, 2), B(1, -3), C(2, 4); x-axis, A(-2,-4), B(6,2), C(3. – 5); y-axis and A(4, -1), B(3, 8), C(-1, 1); y = -2 on the graph and linking them up together to form an angle.

What is mean by Fraction?
A fraction is a part of whole number, and a way to split up a number into equal parts.
Or, A number which is expressed as a quotient is called fraction.
It can be written as the form of p : q, which is equivalent to p / q.
Given that;
A robot can complete 7 tasks in 2/5 hour.
Each task takes the same amount of time.
Now,
Since, 7 tasks = 2/5 hour
So, 1 tasks = 2 / 5×7
= 2 / 35 hour
Thus, The robot take 2 / 35 hour to complete one task.
And, 2/5 hour = 7 tasks
So, 1 hour = 7 x 5 / 2
= 35 / 2
Thus, The robot complete 35/2 tasks in one hour.
Therefore,
a) The robot take 2 / 35 hour to complete one task.
b) The robot complete 35/2 tasks in one hour.

Solve for x.
Help ASAP please!!!
Answer:
The value of x is 4
Step-by-step explanation:
In a right triangle, if a segment is drawn from the right angle ⊥ to the hypotenuse like the given figure, then
∵ The length of one side of the right triangle = (x + 2)
∵ The length of the hypotenuse = x + 5
∴ (x + 2)² = x (x + 5)
∵ (x + 2)² = (x + 2)(x + 2)
∴ (x + 2)(x + 2) = x(x + 5)
→ Simplify the two sides
∵ (x)(x) + (x)(2) + (2)(x) + (2)(2) = (x)(x) + (x)(5)
∴ x² + 2x + 2x + 4 = x² + 5x
→ Add the like terms in the left side
∴ x² + 4x + 4 = x² + 5x
→ Subtract x² from both sides
∵ x² - x² + 4x + 4 = x² - x² + 5x
∴ 4x + 4 = 5x
→ Subtract 4x from both sides
∴ 4x - 4x + 4 = 5x - 4x
∴ 4 = x
∴ The value of x is 4

A party planner estimates a party will cost $200 plus $8 for each person attending. What is the y-intercept of the graph of the linear function representing the total cost of the party?
Answer:
The y intercept is 200
Step-by-step explanation:
Given
Base Cost = 200
Per person =8
Required
Determine the y intercept
First, we need to determine the equation.
The total amount (y) for x persons can be calculated using:
y = Base Cost + Amount per person * x.
This gives
y = 200 + 8 * x
y = 200 + 8x
The general expression of a linear equation is:
y = mx + b
Where b = y intercept
By comparison,
b = 200
Hence, the y intercept is 200

Answer:
El monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.
Step-by-step explanation:
En tanto Josean Hernández solicitó un préstamo de $38,400, y acordó con la financiera devolverlo durante 36 meses a un interés del 5.8%, para determinar la cantidad total a pagar y el monto de cada cuota, es necesario realizar el siguiente cálculo:
(38,400 x 5.6 / 100) + 38,000 = X
2,227.2 + 38,000 = X
40,227.2 = X
40,227.2 / 36 = 1,117.42
Así, el monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.
