slope intercept form
y -y1 = m(x-x1)
y-3 =1/4 (x-4)
distribute
y-3 =1/4 x-1
stand form of a line is Ax +by =c
so subtract 1/4 x from each side
y -3 -1/4 x =-1
add 3 to each side
y-1/4 x =2
-1/4 x +y =2
I would multiply by -4 on both sides to make the 1st term positive and get rid of the fraction
x -4y = -8
Find the slope of the line that crosses through the points (-3, -4) and (2, -3).
slope = (y2-y1)/(x2-x1)
m = (-3--4)/(2--3)
m = (-3+4)/(2+3)
m =(1/5)
m=1/5
Answer:
x = 5/4
y = 15/16
Step-by-step explanation:
Let's solve your system by substitution.
y = 3/4x; 5/2x + 2y = 5
Answer:
Each cookie will have to be sold for at least $0.90 if the profit is to be made is more than $25.
Step-by-step explanation:
The amount spent on supplies is $20.
The number of cookies baked is = 50.
If the profit to be made is more than $25.00 .
Then we can safely say that all the cookies have to be sold for
= $20.00 + $25.00
= $45.00
Therefor the required inequality can be written as
50 x ≥ $45.00 ⇒ x ≥ ⇒ x ≥ $0.90.
Therefore we can say that each cookie will have to be sold for at least $0.90 if the profit is to be made is more than $25.

Answer:
Mass=1068gr
Step-by-step explanation:
Volume= 7.5 cm x 2.53 cm x 7.15 cm=135.7cm^3
Density=7.87gr/cm^3
Mass=Density*Volume=135.7*7.87=1068gr
