Find f(3) f(x)=x+2/x
A) -1/3
B)1/3
C)5/3
D)-5/3
Work Shown:
f(x) = (x+2)/x
f(-3) = (-3+2)/(-3) .... replace every x with -3
f(-3) = -1/(-3)
f(-3) = 1/3
Given point (2,-5) and slope 1, fill in the blanks to put in point slope form. y-____=____(x-___) *
Answer:
y =
[tex] \frac{ - 5}{2} x[/tex]
Step-by-step explanation:
The slope is 1 so that makes it
1x
1x is just x
x
y/x is the slope
-5/2
there is no y-int so the equation is
y= (-5/2)x

find the value of 3v - 10 given that -2v + 4 = 8
Answer:
-16
Step-by-step explanation:
v=-2
I found this because since it is given that -2v+4=8; If v=-2 then the equation is true, because -2(-2) + 4 = 8. So since v=-2, plug in -2 into v of 3v-10; which would be (3(-2))-10, which is equal to -16.

Let z = Equals 38 (cosine (StartFraction pi over 8 EndFraction) + I sine (StartFraction pi Over 8 EndFraction) ) and w = 2 (cosine (StartFraction pi Over 16 EndFraction) + I sine (StartFraction pi Over 16 EndFraction) ) .
What is the product of zw?
40 (cosine (StartFraction pi Over 16 EndFraction) + I sine (StartFraction pi Over 16 EndFraction) )
76 (cosine (StartFraction pi Over 16 EndFraction) + I sine (StartFraction pi Over 16 EndFraction) )
40 (cosine (StartFraction 3 pi Over 16 EndFraction) + I sine (StartFraction 3 pi Over 16 EndFraction) )
76 (cosine (StartFraction 3 pi Over 16 EndFraction) + I sine (StartFraction 3 pi Over 16 EndFraction) )
9514 1404 393
Answer:
d. 76(cos(3π/16) +i·sin(3π/16))
Step-by-step explanation:
To form the product of 38cis(π/8) and 2cis(π/16), multiply the magnitudes and add the angles:
38cis(π/8) × 2cis(π/16) = (38×2)cis(π/8 +π/16) = 76cis(3π/16)
___
In this context, a·cis(b) ≡ a(cos(b) +i·sin(b))
help plz or my teacher will give me a zero
Answer:
Variable x = $2.39 ⇒ price of 1 pound of cashews
Variable y = $1.79 ⇒ price of 1 pound of peanuts
Step-by-step explanation:
Assume that the price of each pound of cashews is $x and the price of each pound of peanuts is $y
∵ The price of 1 pound of cashews = x
∵ The price of 1 pound of peanuts = y
∵ 5 pounds of cashews and 8 pounds of peanuts cost $26.27
∴ 5x + 8y = 26.27 ⇒ (1)
∵ 7 pounds of cashews and 4 pounds of peanuts cost $23.89
∴ 7x + 4y = 23.89 ⇒ (2)
Now we have a system of equations to solve it
→ Multiply equation (2) by -2 to make the coefficients of y equal
in values and different in signs
∵ -2(7x) + -2(4y) = -2(23.89)
∴ -14x - 8y = -47.78 ⇒ (3)
→ Add equations (1) and (3) to eliminate y
∵ (5x + -14x) + (8y + - 8y) = (26.27 + -47.78)
∴ -9x = -21.51
→ Divide both sides by -9 to find x
∴ x = 2.39
→ Substitute x in equation (1) or (2) to find y
∵ 5(2.39) + 8y = 26.27
∴ 11.95 + 8y = 26.27
→ Subtract 11.95 from both sides
∴ 8y = 14.32
→ Divide both sides by 8 to find y
∴ y = 1.79
∴ The price of 1 pound of cashews is $2.39
∴ The price of 1 pound of peanuts is $1.79

In the inequality 2x + $10,000 ≥ $70,000, x represents the salary of an employee in a school district. Which phrase most accurately describes the employee's salary?
Options:
A. At least $30,000
B. At most $30,000
C. Less than $30,000
D. More than $30,000
Answer:
A. At least $30,000
Step-by-step explanation:
Given the inequality :
2x + $10,000 ≥ $70,000 ;
Where x salary of an employee ;
Phrase which describes the employee's salary, x
2x + 10000 ≥ 70000
2x ≥ 70000 - 10000
2x ≥ 60000
x ≥ 60000 / 2
x ≥ 30000
Salary ,x, is greater than or equal to $30000
