Answer:
y= -2x+8
Step-by-step explanation:
y-y₁=m(x-x₁)
This is the point slope form equation that can be used to solve this.
Plug in the slope for m and (6,-4) for (x₁,y₁)
y-(-4)=-2(x-6)
Simplify.
y+4= -2x+12
y= -2x+8
Answer:
EF = 22 , AB = 1
Step-by-step explanation:
the midsegment of a trapezoid is equal to half the sum of the parallel bases
EF = 
(AB + DC ) ← substitute values
x + 6 = (2x - 9 + x + 5) ← multiply both sides by 2 to clear the fraction
2x + 12 = 3x - 4 ( subtract 3x from both sides )
- x + 12 = - 4 ( subtract 12 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Then
EF = x + 6 = 16 + 6 = 22
Similarly
EF = (AB + DC ) , that is
x + 3 = (4x - 3 + 2x + 5 ) ← multiply both sides by 2 to clear the fraction
2x + 6 = 6x + 2 ( subtract 6x from both sides )
- 4x + 6 = 2 ( subtract 6 from both sides )
- 4x = - 4 ( divide both sides by - 4 )
x = 1
Then
AB = 4x - 3 = 4(1) - 3 = 4 - 3 = 1
Answer:
the median is $1.60 greater than the mean
Answer:
I’m pretty sure there’s not enough informatio, what did she start with? A better problem would be ”Lucy started with $15 dollars. She spent 3/5 of her money on a hand bag, she then spent the remainer on 3 shirts that cost $4 each. How much did her handbag cos?” then we would add 3+4 which equals 7 then count how much till we get to $15 (the money which she starts with) then we would know that that hand bag cost $8 (7+8=15)
