Answer:
x = - 6/7
Step-by-step explanation:
Distribute 5 (x - 4) first --> 5x - 20
Combine like-terms: 5x - 20 + 2x = 14 --> 7x - 20 = 14
Subtract 20 on both sides: 7x = -6
Divide both sides by 7: x = -6/7

No, 1/2x+3/4-5/8x-7/8 and 1/8(x+1) are not equivalent expressions.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is 1/2 x+3/4-5/8 x-7/8
Now, 1/2 x-5/8 x+3/4-7/8
-1/8 x- 1/8
-1/8(x+1)
Therefore, the equivalent expression for the given expression is -1/8(x+1).

Answer:
8
Step-by-step explanation:
A system of linear equations has no solution when the equations describe parallel lines. Parallel lines have the same slope. In your equation, the slope is the x-coefficient, 8. A parallel line will have a slope of 8.
The second equation will have a slope of 8 if the system has no solution.

The nth term of the sequence is n^2 + 20
How many terms in the sequence are less than 50
plss help!!
Answer: 5 terms.
Step-by-step explanation:
We know that the n-th term of a sequence is:
Aₙ = n² + 20
Where n can be any natural number, then n ∈ {1, 2, 3, ...}
We want to find how many terms are smaller than 50.
Then we could find the first value of n such that Aₙ is equal or larger than 50.
Then we can solve:
Aₙ = n² + 20 = 50
then:
n² = 50 - 20 = 30
n = √30 = 5.48
This is not a natural number, so we need to round to the next one that is n = 6
This means that the first natural number n such that Aₙ is equal or larger than 50 is n = 6, then for the values:
n = 1, 2, 3, 4, 5
Aₙ is smaller than 50
This means that there are 5 terms of the sequence that are smaller than 50.

They plan to sell the small figures for $8 and the large figures for $10. How many of each figure should Pablo and Kenneth create to earn the most amount of money possible? For full credit, explain HOW you got your answer and WHY you think this is the best combination of figures.
Answer:
Not enough information
Step-by-step explanation:
There is no limit to how many figures you can create. There is not enough information to solve this. If this is only a part of the question, try to include all of it.
Answer: I disagree. If Pablo has enough time to make 10 figures. He could make 8 of the large figures and make $80.00 and then make 2 of the large figures and make $16. Together with the 8 small and 2 large figures they would make $96.00

Write the sum as a product.
sin(x)-sin(4x)
Step-by-step explanation:
Given
sin(x) - sin(4x)
= 2 cos (( x + 4x)/2) * sin ( ( x - 4x) / 2))
= 2 cos 5x/2 • sin -3x / 2
= - 2 cos 5x/2 • sin 3x/2
Hope it helps :)❤
The sum sin(x) - sin(4x) can be written as a product as 2 sin (5x/2) cos (3x/2).
What are Trigonometric Ratios?Trigonometric ratios are the ratios which is described for two sides of a right angled triangle.
The main three trigonometric ratios are sine, cosine and tangent functions.
We have the trigonometric formula that,
sin A - sin B = 2 sin ([tex]\frac{A+B}{2}[/tex]) cos ([tex]\frac{A-B}{2}[/tex])
Here the sum is, sin(x) - sin(4x) where A = x and B = 4x.
sin(x) - sin(4x) = 2 sin ((x+4x)/2) cos ((x-4x)/2)
= 2 sin (5x/2) cos (-3x/2)
We also have, cos(-x) = cos(x).
So, sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2)
Hence the product form is sin(x) - sin(4x) = 2 sin (5x/2) cos (3x/2).

What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( 3 , 106 )
Let the second point be Q ( 6 , 187 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 187 - 106 ) / 3
Slope m = 27
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 106 = 27 ( x - 3 )
y - 106 = 27x - 81
Adding 106 on both sides , we get
y = 27x + 25 be equation (1)
Now , let the equation of line be represented as B
And , the value of B is
Let the first point be R ( 3 , 105 )
Let the second point be S ( 6 , 165 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 165 - 105 ) / 3
Slope m = 20
Now , the equation of line is y - y₁ = m ( x - x₁ )
Substituting the values in the equation , we get
y - 105 = 20 ( x - 3 )
y - 105 = 20x - 60
Adding 105 on both sides , we get
y = 20x + 45 be equation (2)
Now , when x = 1
Substitute the value of x = 1 in equation (1) and equation (2) , we get
y₁ = 27 + 25 = $ 52
y₂ = 20 + 45 = $ 65
So , health club B costs $ 7 less than health club A every month
Hence , the equation of lines is solved
