Step-by-step explanation:
Solve for x:
8 x + 26 - 3/x + 6/x^2 = 0
Hint: | Write the left hand side as a single fraction.
Bring 8 x + 26 - 3/x + 6/x^2 together using the common denominator x^2:
(8 x^3 + 26 x^2 - 3 x + 6)/x^2 = 0
Hint: | Multiply both sides by a polynomial to clear fractions.
Multiply both sides by x^2:
8 x^3 + 26 x^2 - 3 x + 6 = 0
Hint: | Look for a simple substitution that eliminates the quadratic term of 8 x^3 + 26 x^2 - 3 x + 6.
Eliminate the quadratic term by substituting y = x + 13/12:
6 - 3 (y - 13/12) + 26 (y - 13/12)^2 + 8 (y - 13/12)^3 = 0
Hint: | Write the cubic polynomial on the left hand side in standard form.
Expand out terms of the left hand side:
8 y^3 - (187 y)/6 + 799/27 = 0
Hint: | Write the cubic equation in standard form.
Divide both sides by 8:
y^3 - (187 y)/48 + 799/216 = 0
Hint: | Perform the substitution y = z + λ/z.
Change coordinates by substituting y = z + λ/z, where λ is a constant value that will be determined later:
799/216 - 187/48 (z + λ/z) + (z + λ/z)^3 = 0
Hint: | Transform the rational equation into a polynomial equation.
Multiply both sides by z^3 and collect in terms of z:
z^6 + z^4 (3 λ - 187/48) + (799 z^3)/216 + z^2 (3 λ^2 - (187 λ)/48) + λ^3 = 0
Hint: | Find an appropriate value for λ in order to make the coefficients of z^2 and z^4 both zero.
Substitute λ = 187/144 and then u = z^3, yielding a quadratic equation in the variable u:
u^2 + (799 u)/216 + 6539203/2985984 = 0
Hint: | Solve for u.
Find the positive solution to the quadratic equation:
u = (17 (9 sqrt(157) - 188))/1728
Hint: | Perform back substitution on u = (17 (9 sqrt(157) - 188))/1728.
Substitute back for u = z^3:
z^3 = (17 (9 sqrt(157) - 188))/1728
Hint: | Take the cube root of both sides.
Taking cube roots gives 1/12 17^(1/3) (-(188 - 9 sqrt(157)))^(1/3) times the third roots of unity:
z = 1/12 17^(1/3) (-(188 - 9 sqrt(157)))^(1/3) or z = -1/12 (-1)^(2/3) 17^(1/3) (188 - 9 sqrt(157))^(1/3) or z = -1/12 17^(1/3) (188 - 9 sqrt(157))^(1/3)
Hint: | Perform back substitution with y = z + 187/(144 z).
Substitute each value of z into y = z + 187/(144 z):
y = 1/12 (-17 (188 - 9 sqrt(157)))^(1/3) - (11 (-17)^(2/3))/(12 (188 - 9 sqrt(157))^(1/3)) or y = 11/12 17^(2/3) ((-1)/(188 - 9 sqrt(157)))^(1/3) - 1/12 (-1)^(2/3) (17 (188 - 9 sqrt(157)))^(1/3) or y = -(11 17^(2/3))/(12 (188 - 9 sqrt(157))^(1/3)) - 1/12 (17 (188 - 9 sqrt(157)))^(1/3)
Hint: | Simplify each solution.
Bring each solution to a common denominator and simplify:
y = 1/12 (153 sqrt(157) - 3196)^(1/3) - (11 (-17)^(2/3))/(12 (188 - 9 sqrt(157))^(1/3)) or y = 1/12 17^(1/3) (11 ((-17)/(188 - 9 sqrt(157)))^(1/3) - (-1)^(2/3) (188 - 9 sqrt(157))^(1/3)) or y = -1/12 17^(1/3) (1/(188 - 9 sqrt(157)))^(1/3) ((188 - 9 sqrt(157))^(2/3) + 11 17^(1/3))
Hint: | Perform back substitution on the three roots.
Substitute back for x = y - 13/12:
Answer: x = -13/12 - (11 (-17)^(2/3))/(12 (188 - 9 sqrt(157))^(1/3)) + 1/12 (153 sqrt(157) - 3196)^(1/3) or x = 1/12 17^(1/3) (11 (-17/(188 - 9 sqrt(157)))^(1/3) - (-1)^(2/3) (188 - 9 sqrt(157))^(1/3)) - 13/12 or x = -1/12 (17/(188 - 9 sqrt(157)))^(1/3) (11 17^(1/3) + (188 - 9 sqrt(157))^(2/3)) - 13/12

Logan wants to have $130,000 to pay for a surgery on his retractable forearm claws in 30 months. If he can invest money in an account right now that will give him 7.5% interest compounded monthly, how much would he have to
invest now to end up with the amount needed for the surgery later on?
Answers
Answer: $107,836.69 or about $107,837 (to the nearest dollar)
Step-by-step explanation:
Formula to the accumulated amount received after investing principal amount (P) at rate of interest (r) compounded monthly for t months :
[tex]A=P(1+\dfrac{r}{12})^{t}[/tex]
As per given , A = $130,000
r= 7.5% = 0.075
t= 30 months
Now,
[tex]130000=P(1+\dfrac{0.075}{12})^{30}\\\\\Rightarrow 130000=P(1+0.00625)^{30}\\\\\Rightarrow 130000=P(1.00625)^{30}\\\\\Rightarrow 130000=P \times1.20552661036\\\\\Rightarrow\ P=\dfrac{130000}{1.2055266}=107,836.69[/tex]
Hence he need to invest $107,836.69 .

Answer:
two equal, real solutions
Step-by-step explanation:
The quickest way to determine this is to find the discriminant b^2 - 4ac. If this determinant (D) is > 0, the quadratic has two different real roots; if + 0, the quadratic has two equal real roots, and if < 0, the quadratic has two imaginary or complex roots.
Here a = 5, b = 30 and c = 45. The discriminant is
30^2 - 4(5)(45) = 900 - 900 = 0
and so this quadratic has two equal, real solutions.

Step-by-step explanation:
Given
Represent bones eaten Today with T and yesterday with Y
Required
Write the equation
In the first statement, we have that:
[tex]T = 2Y[/tex]
Reading further; In the second statement
[tex]T + 2Y = 15[/tex]
Hence, the equations are:
[tex]T = 2Y[/tex] and [tex]T + 2Y = 15[/tex]
Solving further:
Substitute 2Y for T in the second equation
[tex]2Y + 2Y = 15[/tex]
[tex]4Y = 15[/tex]
Divide both sides by 4
[tex]Y = \frac{15}{4}[/tex]

Step-by-step explanation:
The frequency and the time period is related by the formula as follows :
[tex]f=\dfrac{1}{T}[/tex]
Here, f is frequency and T is time period
Now, we need to solve T in terms of f.
Firstly, cross multiplying the above equation,
[tex]f\times T=1[/tex]
Now dividing both sides by T.
[tex]\dfrac{f\times T}{T}=\dfrac{1}{T}\\\\f=\dfrac{1}{T}[/tex]

Answers
Answer:
(a) The value of P (X = 1, Y = 2) is 0.1583.
(b) The value of P (X + Y = 1) is 0.1055.
Step-by-step explanation:
It is provided that:
[tex]X\sim Bin(n=4,p=0.25)\\\\Y\sim Bin(n=4,p=0.50)[/tex]
The variables X and Y are independent random variables.
The probability mass function of a Binomial distribution is:
[tex]P(U=u)={n\choose u}(p)^{u}(1-p)^{n-u};\ u=0,1,2,3...[/tex]
(a)
Compute the value of P (X = 1, Y = 2) as follows:
[tex]P(X=1,Y=2)=[{n\choose x}(p_{x})^{x}(1-p_{x})^{n-x}]\times [{n\choose y}(p_{y})^{y}(1-p_{y})^{n-y}][/tex]; Independent
[tex]=[{4\choose 1}(0.25)^{1}(1-0.25)^{4-1}]\times [{4\choose 2}(0.50)^{2}(1-0.50)^{4-2}]\\\\=0.422\times 0.375\\\\=0.15825\\\\\approx 0.1583[/tex]
Thus, the value of P (X = 1, Y = 2) is 0.1583.
(b)
Compute the value of P (X + Y = 1) as follows:
[tex]P(X+Y=1)=P(X=0,Y=1)+P(X=1,Y=0)[/tex]
[tex]=\{[{4\choose 0}(0.25)^{0}(1-0.25)^{4-0}]\times [{4\choose 1}(0.50)^{1}(1-0.50)^{4-1}]\}\\+\{[{4\choose 1}(0.25)^{1}(1-0.25)^{4-1}]\times [{4\choose 0}(0.50)^{0}(1-0.50)^{4-0}]\}\\\\=(0.3164\times 0.25)+(0.422\times0.0625)\\\\=0.0791+0.0264\\\\=0.1055[/tex]
Thus, the value of P (X + Y = 1) is 0.1055.

4(1000) +11(100) + 24(10,000) +11(1000) = 256,100
Step-by-step explanation:
Maybe you want to add 4000 +1100 to 24(10,000) +11,000.
1 thousand = 10 hundreds, so 4000 = 40 hundreds
4000 +1100 = (40 +11) hundreds = 51 hundreds
__
1 ten-thousand = 10 thousands, so 24(10,000) = 240 thousands
24(10,000) +11,000 = (240 +11) thousands = 251 thousands
__
So, we want to add 251,000 and 51 hundreds. The latter can be considered to be 5000 +100, so we have ...
251,000 +5100 = 251,000 +5,100 = (251 +5) thousands + 1 hundred
= 256,100

Answer:
[tex]x>6[/tex]
Step-by-step explanation:
So we have the inequality:
[tex]-5\sqrt{x-2}<-10[/tex]
Divide both sides by -5. Since we're dividing by a negative, the sign changes:
[tex]\sqrt{x-2} >2[/tex]
Square both sides:
[tex]\sqrt{x-2}^2>2^2\\x-2>4[/tex]
Add two to both sides:
[tex](x-2)+2>4+2\\x>6[/tex]
Therefore, x>6.
However, the expression under the square root cannot be negative. Therefore, there is another inequality. Set the expression under the square root to greater than or equal to 0:
[tex]x-2\geq 0[/tex]
Add 2 to both sides:
[tex]x\geq 2[/tex]
However, previously, we determined that x must be greater than 6. That overrules this, so we will ignore it.
Thus, the answer is:
[tex]x>6[/tex]
So, drag the fourth option onto 6 on the line. This is an open circle and points to the right, so it includes all values greater than 6 not including 6.
Answer:
x > 6
Step-by-step explanation:
Drag the fourth option onto 6 on the line. This is an open circle and points to the right, so it includes all values greater than 6 not including 6.

Answer:
x = 17
KNM = 131
Step-by-step explanation:
(8x - 5) + (4x - 19) = 180
12x - 24 = 180
12x = 204
x = 17
Answer:
x = 17
Step-by-step explanation:
Opposite Angles must be the Same Value so In other words, 2(8x - 5) + 2(4x - 19) = 360.
2(8x - 5) + 2(4x - 19) = 360
24x - 48 = 360
24x = 408
x = 17

Answer:
-5
Step-by-step explanation:
think of it on a number line the number furthest to the left is always the smallest and the numbers to the right are bigger
Answer:
-5
Step-by-step explanation:
On a number line, there are negative and positive numbers.
The numbers -2, -4, and -5 are negative (see the little dash sign - ? that's negative).
2 is positive (you see no sign or a plus + before it).
The number line is a good way to learn negative and positive numbers.
go left, and the numbers go smaller
go right and they get bigger
-5 is the smallest since it is the most far left on the number line.

Question: Which expression is equivalent to
[tex] \frac{4}{9}(2n - 3)[/tex]
Answers
Answer:
[tex] \frac{8}{9}n - 1\frac{1}{3} [/tex]
Step-by-step explanation:
To find the expression that is equivalent to [tex] \frac{4}{9}(2n - 3) [/tex], let's simply as follows:
[tex] \frac{4}{9}(2n) - \frac{4}{9}(3) [/tex] (distributive property of multiplication)
[tex] \frac{4*2n}{9} - \frac{4*3}{9} [/tex]
[tex] \frac{4*2n}{9} - \frac{4*1}{3} [/tex]
[tex] \frac{8n}{9} - \frac{4}{3} [/tex]
[tex] = \frac{8}{9}n - 1\frac{1}{3} [/tex]
[tex] \frac{8}{9}n - 1\frac{1}{3} [/tex] is equivalent to [tex] \frac{4}{9}(2n - 3) [/tex].
