Answer:
Combining and simplifying [tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex] we get [tex]\mathbf{-4x-34y-32}[/tex] or we can write as [tex]\mathbf{48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})}[/tex]
Step-by-step explanation:
We need to combine and simplify
[tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex]
First we will combine like terms and then perform the mathematical operations like addition or subtraction.
Like terms: terms having same variable
[tex]48(\frac{1}{4}x-\frac{2}{6}x-\frac{1}{3}y-\frac{3}{8}y-\frac{2}{3})[/tex]
Now we take LCM of like terms
[tex]=48(\frac{1}{4}x-\frac{2}{6}x-\frac{1}{3}y-\frac{3}{8}y-\frac{2}{3})\\=48(\frac{x*3-2x*2}{12} +\frac{-y*8-3y*3}{24}- \frac{2}{3})\\=48(\frac{3x-4x}{12} +\frac{-8y-9y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} +\frac{-17y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})[/tex]
Now, we can multiply 48 with terms inside the bracket.
we can simplify the terms if they are both divisible by same number.
[tex]=48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})\\=48(\frac{-x}{12} )-48(\frac{17y}{24})-48(\frac{2}{3}))\\=-4x-34y-32[/tex]
So, Combining and simplifying [tex]48(\frac{1}{4}x-\frac{1}{3}y-\frac{2}{6}x-\frac{3}{8}y-\frac{2}{3})[/tex] we get [tex]\mathbf{-4x-34y-32}[/tex] or we can write as [tex]\mathbf{48(\frac{-x}{12} -\frac{17y}{24}- \frac{2}{3})}[/tex]
Solve the system using the elimination method. Answer in simplest fraction form. x+2y-z=3 -2x-y+z=-1 6x-3y-z=-7
For a real value of z, the general solution of above system of equations is x = -1/3 + (1/3)z, y = 5/3 + (1/3)z and z = z
In this question, we have been given a system of equations.
x+2y-z=3 ...........(1)
-2x-y+z=-1 ............(2)
6x-3y-z=-7 ...........(3)
We need to solve above system of equations using the elimination method.
We solve above system of equations by Gaussian elimination method.
First we write above system f equations in as an augmented matrix.
[tex]\begin{bmatrix}1 & 2 & -1 &|& 3 \\-2 & -1 & 1 &|& -1 \\6 & -3 & -1 &|& -7\end{bmatrix}[/tex]
We convert the augmented matrix into the row echelon form as:
[tex]\begin{bmatrix}1 & 2 & -1 & 3 \\0 & 3 & -1 & 5 \\0 & 0 & 0 & 0\end{bmatrix}[/tex]
So, we get an system of equations as:
x + 2y -z = 3 ............(4)
3y - z = 5 ...........(5)
From equation (5),
y = 5/3 + (1/3)z
Substitute above value of y in equation (4),
x = 3 - 2[5/3 + (1/3)z] + z
x = -(1/3) + (1/3)z
So, the general solution is,
[tex]\left(\begin{matrix}\frac{-1}{3}+\frac{1}{3}*z \\\\\frac{5}{3}+\frac{1}{3}*z \\\\z\end{matrix}\right)[/tex]
Therefore, for a real value of z, the general solution of above system of equations is x = -1/3 + (1/3)z, y = 5/3 + (1/3)z and z = z

The first side of a triangle measures 5 in. less than the second side, the third side is 3 in. more than the first side, and the
perimeter is 17 in. How long is the third side?
If s represents the length of the second side, which of the following represents the length of the third side?
s-5
S-2
s+3
Answer:
see explanation
Step-by-step explanation:
let s be the second side then the first side is s - 5 and the third side is
s - 5 + 3 = s - 2
-------------------------
the perimeter (P) is the sum of the 3 sides of the triangle.
given P = 17 , then
s - 5 + s + s - 2 = 17
3s - 7 = 17 ( add 7 to both sides )
3s = 24 ( divide both sides by 3 )
s = 8
third side = s - 2 = 8 - 2 = 6 in

4) The speed of light is 3 x 10^8 meters per second. The distance to the
sun is 1.5 x 10^11 meters. How long does it take light to reach the Earth
from the Sun. 0.5 seconds
5 seconds
50 seconds
500 seconds
Answer:
500 seconds
Step-by-step explanation:
This is a distance = rate × time problem
d = 1.5 × 10^11 m
rate = 3 × 10^8 m/s
So, d = rate × t
t = d ÷ rate = 1.5 × 10^11 m ÷ 3 × 10^8 m/s = 500 s

Answer:
B: 22.5 degrees
Step-by-step explanation:
The interior angles of a pentagon add up to 540 degrees
(if you dont believe me you can turn a pentagon into three triangles, 3x180 = 540)
So you have four same angles say measure "x" degrees, and one final one that measures "5x" degrees, so 9x = 540, and x = 60
Unless I read the problem wrong, 60 degrees is the answer which is not an option :P
Edit: Yea I read it wrong, the final angle is 5 times the other four angles COMBINED, so that angle measures "20x" degrees.
The total would be 24x = 540, and so x = 22.5

The domain on which the following function is increasing
The domain on which of the following function is increasing is [0,4].
Given:
The graph of a function.
To find:
The domain on which of the following function is increasing.
Domain is the set of x-values or input values.
From the given graph it is clear that the vertex of the given function is at (4,75).
Before the point (4,75) the graph is increasing and after the point (4,75) the graph is decreasing.
The function is defined for 0≤x≤9 .
Since the graph is increasing when 0≤x≤4 , therefore the function is increasing over the interval [0,4].
Therefore, the domain on which of the following function is increasing is [0,4].
What is domain?
The domain is the value that x can take from a given function and codomain is the value of y from a function.

Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.
