Solpe intercpt form is y=mx+b
m=slope
b=y intercept
so exg
if you have
3x+8y=8
subtract 3x from both sides
8y=3x+8
divide boh tsides by 8
y=8/3x+1
y intercpt=1
slope=8/3
The GCF of the first two terms: 5h²
The GCF of the last two terms: 4
5h³ and 20h²
Both of these terms are divisible by 5. (constant)
Both of these terms also have at least 2 h's. (variable)
4h and 16
Both of these terms are divisible by 4.
Only one term has a variable, so that has to be left out.
Answer:
[1] x - 6y = 3
[2] x + 2y = 5
Graphic Representation of the Equations :
-6y + x = 3 2y + x = 5
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -2y + 5
// Plug this in for variable x in equation [1]
[1] (-2y+5) - 6y = 3
[1] - 8y = -2
// Solve equation [1] for the variable y
[1] 8y = 2
[1] y = 1/4
// By now we know this much :
x = -2y+5
y = 1/4
// Use the y value to solve for x
x = -2(1/4)+5 = 9/2
Solution :
{x,y} = {9/2,1/4}
Answer:
A (-3,9)
Step-by-step explanation:
ok easy they they us
R(2,1) and R'(-4,8)
subtract 6 from y and add 7 to y
ok lets solve for S'
S(3,2) now subtract 6 and add 7
(3,2)+(-6,7)
(-3,9)
Put gallons over days so gal/days
and then input the numbers
2559/30 = 85.3
85.3 is your answer
