Answer:
-2/3
Step-by-step explanation:
Answer:
y = - 3x + 9 or (y - 6) = - 3(x - 1)
Step-by-step explanation:
I'm assuming you are looking for the equation of the line.
First, let's find the slope of the line, which we use equation (y1-y2) / (x1-x2)
x1: 1 x2: 2
y1: 6 y2: 3
(6-3) / (1-2) = 3 / -1 = -3
The slope of the line is -3.
The equation for slope-intercept form is y = mx + b, where m is slope and b is the y - intercept.
y = -3x+b
Now substitute a set of points in (any coordinates work). I'll use (1, 6)
6 = -3(1)+b
6 = - 3 + b
b = 9
So our equation in slope intercept form is y = - 3x + 9
You can also write this in point slope form, (y-y1) = m (x-x1) m is still slope
(y - 6) = - 3(x - 1)
Answer:
28.84
Step-by-step explanation:
Simplify the inside of root first
147 / 3 = 49
49 + 3 = 52
4 (root) 52 = 28.8444102
Answer:
5 gallons
Step-by-step explanation:
3/4 + 6/8 + 20/8 + 1
6/8 + 6/8 + 20/8 + 8/8
40/8 = 5 gallons
Answer:
nope
Step-by-step explanation:
they do not have the same exponent
no matter what the number with the x is, as long as the x's have the same exponent, they can be combined...
but in this problem such is not the case, because one x is to the power of 2 and the other is to the power of 1...
so, not in this problem...
