Answer:
5 cups of flour needed to make 60 cookies.
Step-by-step explanation:
24 cookies → 2 cups of flour
1 cookies → (2/24) cups of flour
60 cookies → [(2/24)*60 ] cups of flour
60 cookies → 5 cups of flour needed
I believe the answer is 7x-y
3y=x-3
y=1/3x-1
Perpendicular slope: -3
y=-3x+b
Plug in the coordinates in the equation:
-9=-3(5)+b
-9=-15+b
4=b
Equation: y=-3x+4
Also, when finding the perpendicular slope you take the reciprocal of the original slope and make it negative if it is positive and make it positive if it’s negative.
Answer:
x=3 and x=-1.25
Step-by-step explanation:
4x^2-7x=15
subtract 15 from each side:
4x^2-7x-15=0
factor (trying different numbers that the sum is 7 and the quotient is 15)
(2x-6 )(2x+2.5 )=0
2x-6=0 add 6 to each side
2x=6
x=3
2x+2.5=0 subtract 2.5 from each side
2x=-2.5
x=-1.25
It moves roughly 5 inches a day. (p.s you made a mistake, there is 365 days in a year not 356)
