Write an equation of the line passing through point P(4,0) that is parallel to the line -x + 2y = 12.
Answers
-x+2y=12
2y=x+12
y=(1/2)x+6
the slope is 1/2
using the point-slope form of a line...
y-y1=m(x-x1) where m is the slope and (x1,y1) is (4,0)
y-0=(1/2)(x-4)
y=(1/2)x-2 is the equation of the line
check: 0=(1/2)(4)-2
0=2-2
0=0
___________________
Explanation:
-x+2y=12
2y=12+x
divide both sides by 2
y= 6+ x/2
as they are parallel, therefore, their slopes are equal
hence,
put P(4;0) in the equation to find y intercept( y=kx+b, there b is y intercept)
0= 1/2 * 4+ b
b=-2
hence,
our equation is
y=1/2x-2

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?
Answers
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

Answers
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

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.
