Answer:
n = 19.2
Step-by-step explanation:
12 / 5 = n / 8
n = 12 * 8 / 5
n = 96 / 5
n = 19.2
The slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
In this case the slope is...
1
The y-intercept is...
(0, -4)
Plug these numbers in for m and b respectively:
y = 1x + (-4)
y = x - 4

Answer:
8x + 13
Step-by-step explanation:
"Like terms" means the same kind of algebraic expression...the 6x and the 2x are "like terms" because they both have an x in them. The 9 and the 4 are both constants, which means they are plain numbers. So 6x and 2x is 8x .
9+4 is 13 just like elementary school.
So all together,
6x + 9 + 2x + 4
6x + 2x + 9 + 4
8x + 13
We can rearrange the terms because the problem has all addition in between the terms.
Answer:
Step-by-step explanation:
No solutions....means the lines are parallel...means ur 2 equations have to have the same slope but different y intercepts
y = 2x + 4 and y = 2x + 3
========================
Infinite solutions...means u have the same line
y = 2x + 4 and 2y = 4x + 8....notice how if u reduce the 2nd one by dividing everything by 2 u get y = 2x + 4...same line
========================
1 solution....means ur equations will have different slopes and different y intercepts.
y = 2x + 4 and y = 4x + 2
now, u can pick which one u want :)
Answer:
No solution
Step-by-step explanation:
Original Equation:
5x - 5 = 5x + 7
Add 5 to both sides
5x = 5x + 12
So we already know that this equation is not true, making it no solution
