In the equation, what is the value of x? −4(x + 4x) = 2(2 − x) + 10 A) − 7/ 9 B) − 9/ 7 C) 7 9 D) 9/ 7 Submit
The solution to the given equation is x = -7/9, after simplifying and solving for x.
Explanation:To simplify the equation -4(x + 4x) = 2(2 - x) + 10, start by combining like terms within the parentheses: -4(5x) = 2(2 - x) + 10. This leads to -20x = 4 - 2x + 10. Further simplifying, you get -20x = 14 - 2x. Now, add 2x to both sides to eliminate the variable on the right, resulting in -18x = 14. To isolate x, divide both sides by -18, yielding x = -14/18, which can be further reduced to x = -7/9. In summary, the equation simplifies to x = -7/9 after a series of steps.

A veterinarian divided 2/5 of a bottle of medicine equally among some sick cats. She gave each cat 1/5 of a bottle of medicine. How many sick cats were there?
The veterinarian gave each cat 1/5 of a bottle of medicine. By dividing the total medicine (2/5 of a bottle) by 1/5, we find that there were 2 sick cats.
Explanation:To find the number of sick cats, we need to divide the amount of medicine given to the cats by the amount given to each cat. Since each cat received 1/5 of a bottle, we can divide the total medicine (2/5 of a bottle) by 1/5 to find the number of cats. This can be done by multiplying the total medicine by the reciprocal of 1/5, which is 5/1.
Convert 2/5 to an improper fraction: 2/5 = 2 ÷ 5 = 2/5Multiply the total medicine by the reciprocal of 1/5: 2/5 × 5/1 = 2 × 5 / 5 × 1 = 10 / 5 = 2Therefore, there were 2 sick cats.

Answer:
-5,120
Step-by-step explanation:
The pattern is increasing by x*2
I would say -100
You would find this out by identifying your 'a' which is the first number of the sequence, in this case it is -5
Then you would find the common ratio. You do that by dividing any two of the numbers after your 'a' For this one I chose to divide -20 by -10 and that gets you 2.
You would multiply those together, getting you -10.
So, from here you would put the term you are trying to find (in this case it is the 11th term) and subtract it by one
11-1=10
Lastly, you would multiply your -10 by 10 and get yourself a -100

Answer:
The Second Option is your Answer ( Option 2)
Step-by-step explanation:
1) proof ( replace h with -2)
|-2-2| = 4
|-4| = 4
2) proof ( replace h with 6)
|6-2| = 4
|4|=4
Hopes this helps !
Answer:
[tex]h = -2\\h = 6[/tex]
Step-by-step explanation:
The absolute value is a function that transforms any value x into a positive number.
Therefore, for the function [tex]f(x) = |x|[/tex] x> 0 for all real numbers.
Then the equation:
[tex]|h-2| = 4[/tex] has two cases
[tex](h-2) = 4[/tex] if [tex]h > 2[/tex] (i)
[tex]-(h-2) = 4[/tex] if [tex]h < 2[/tex] (ii)
We solve the case (i)
[tex]h = 4 + 2\\h = 6[/tex]
We solve the case (ii)
[tex]-h +2 = 4\\h = 2-4\\h = -2[/tex]
Then the solution is:
[tex]h = -2[/tex] or [tex]h = 6[/tex]

A 1/2 yard of ribbon is needed for a craft project. How much ribbon will remain from a piece that measures 7/8 yard?
To find out how much ribbon is left after using 1/2 yard from a piece that is 7/8 yard long, convert 1/2 yard to 4/8 and subtract from 7/8, leaving you with 3/8 yard of ribbon remaining.
To determine how much ribbon will remain after using 1/2 yard for a craft project from a piece that measures 7/8 yard, you need to subtract the amount used from the total length you have. Since we are working in yards, ensure both amounts are in the same units. Here are the steps to find the remaining ribbon:
Start with the total length of ribbon: 7/8 yard.
Subtract the length of ribbon used for the project: 1/2 yard.
Convert 1/2 yard to an equivalent fraction with a denominator of 8, which is 4/8 yard.
Subtract 4/8 yard from 7/8 yard to find the remaining length.
7/8 yard - 4/8 yard = 3/8 yard remaining.
So, after using 1/2 yard of ribbon for a craft project, you will have 3/8 yard of ribbon left from the original 7/8 yard piece.

Prove:Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
A = sinx - sin3x,
B = -sin3x + sin5x
First A:
The average of x and 3x is 2x, and they (x and 3x, that is) are each a distance of x from this average. That's fancy talk for:
x = 2x-x,
3x = 2x+x.
So, A = sin(2x-x) - sin(2x+x)
Using angle sum formulas:
A = (sin2x cosx - cos2x sinx) - (sin2x cosx + cos2x sinx)
A = -2 cos2x sinx
Similarly,
B = -sin(4x-x) + sin(4x+x)
= -(sin4x cosx - cos4x sinx) + (sin4x cosx + cos4x sinx)
B = 2 cos4x sinx
Now,
sinx - 2sin3x + sin5x = A+B = -2 cos2x sinx + 2 cos4x sinx
= 2 sinx (cos4x - cos2x).
Sinx-2sin3x+sin5x=2sinx(cos4x-cos2x)
Step-by-step explanation:sinx - 2sin3x + sin5x = sinx - sin(3x) + sin(5x)- sin(3x)
= 2· cos[(x+3x)/2] · sin[(x-3x)/2] + 2·cos[(5x+3x)/2]· sin[(5x-3x)/2]
= 2· cos(2x) ·sin(-x) + 2· cos(4x) · sin(x)
= -2·cos(2x)·sinx + 2· cos(4x)·sinx
= 2·sinx · [ cos(4x)- cos(2x)]

Minerva buys used bicycles, repairs them, and sells them for a profit. She bought a bicycle for $10, repaired it, and sold it for $50. What was the percent increase in the price of the bicycle.
A. 400%
B. 80%
C. 40%
D. 4%
it is an increase of 400%
Final answer:
The percent increase in Minerva's bicycle price is calculated by subtracting the original price from the new price, dividing by the original price, and then multiplying by 100%. The calculation results in a 400% increase.
Explanation:
The percent increase in the price of the bicycle that Minerva bought and sold is calculated using the formula for percent change, which is (New Price - Original Price) / Original Price times 100%. In this case, the original price is $10 and the new price is $50.
To calculate the percent increase:
($50 - $10) / $10 times 100% = $40 / $10 times 100% = 4 times 100% = 400%.
Therefore, the correct answer is 400%, which is option A.

c. y= -1.560x+ 4.105
d. y = 4.105x – 1 560
Answer: B. y = 1.560x - 4.105*****
Answer:
Option B.
Step-by-step explanation:
The general equation of best fit line is
[tex]y=mx+b[/tex] .... (1)
where, m is slope and b is y-intercept.
[tex]m=\frac{\sum_{i=1}^nx_iy_i-n\overline{x}\overline{y}}{\sum_{i=1}^nx_i^2-n\overline{x}^2}[/tex]
[tex]b=\overline{y}-b\overline{x}[/tex]
Using the graphing calculator we get
[tex]m=1.56015\approx 1.560[/tex]
[tex]b=-4.10526\approx -4.105[/tex]
Substitute m=1.560 and b=-4.105 in equation (1).
[tex]y=1.560x-4.105[/tex]
The equation of the line of best fit for the following data y = 1.560x - 4.105.
Therefore, the correct option is B.

Answer:
f(x)⁻¹ = x³ + 2
Step-by-step explanation:
Find the inverse of f(x) = ∛(x - 2).
The first step is to let f(x) = y
y = ∛(x - 2)
Then make x the subject of the formula
y³ = [∛(x - 2)]³
y³ = x - 2
x = y³ + 2
∴ f(x)⁻¹ = y³ + 2
Replacing y with x we have.
f(x)⁻¹ = x³ + 2

A-3296.135 i think
Step-by-step explanation:
To find the area of the unshaded portion of a figure containing a trapezoid and a rhombus, calculate the area of each figure first using their respective formulas. Subtract the area of the overlapping (shaded) region from the total to find the area of the unshaded portion.
Explanation:The problem asks to find the area of the unshaded portion of a figure, which includes a trapezoid and a rhombus. Since we don't have the specific values of the sides and heights of each figure, a general approach would be to calculate the area of each figure first, then subtract the area of the shaded (overlapping) region from it.
The formula for the area of a trapezoid is A = 1/2 (a+b)h, where 'a' and 'b' are the lengths of the parallel sides and 'h' is the height. For the rhombus, the formula is A = 1/2 (d1 * d2), where 'd1' and 'd2' are the diagonals.
Assuming you can measure and determine the shaded region, you would compute its area as well and subtract this from the total of the previous two calculations. This would give you the area of the unshaded portion.
