The answer is D, y - 4 = -2(x - 1).
Point Slope Form: y - y₁ = m(x - x₁)
Info Given:
Coordinates - (1,4)
Slope: -2
(1,4)
x₁ y₁
Plug slope and point into formula: y - 4 = -2(x -1)
Answer:
the supplementary angle to 313 would be 49.
Step-by-step explanation:
the supplement of an angle is when tow angles add up to equal 180 degrees. therefore, if you subtract 131 from 180, you would get the answer of 49 degrees.
The answer for this question is =
y = 1/2x+ 8
Work
y= mx +b:
y= 1/2x+b
x= -4
y=6
6=1/2(-4)+b
6=-2+b
b=8
y=1/2x+8
6=
Answer:
1 - 3/5 = 5/5 - 3/5 = 2/5 = 4/10 = 40%
David purchased some cookies at the cost of
5 for $4 (5/4=1.25) and
sold them at 4 for $5(4/5=0.80).
To find cost per cookie subtract 1.25-0.80=0.45
David made a profit of $180 in total ( divide profit per cookie cost: 180/0.45= 400)
How many cookies did David purchase to make that much money?
He needed to make 400 cookie to make the profit of $180.
