Answer:
Decreasing
Step-by-step explanation:
Point slope form: y - y1 = m (x - x1)
-------------------------------------------------
first you need to find the slope(m) by using the slope formula (seen below)
y2 - y1
m= ---------
x2 - x1
9 - 15
m= ---------
1 - (-2)
-6
m= --------- = -2
3
then choose either one of the coordinates you'd like and plug it in.
Im gonna use (-2, 15)
(y - 15) = -2 (x - (-2))
or
(y - 15) = -2 (x + 2)
slope intercept form: y = mx + b
-----------------------------------------------
you can use the slope formula to find that the slope(m) is -2
y = -2x + b
you can then plug in a coordinate to find b (the y-intercept)
I'll use (-2,15)
15 = -2(-2) +b
15 = 4 + b
-4 -4
---------
11 = b
in conclusion:
the slope(m) = -2
when (-2,15) is used
x = -2
y = 15
b = 11
standard form: ax + by = c
----------------------------------------
using the same coordinate (-2,15)
-2a + 15b = c
Answer:
9/20
Step-by-step explanation:
<h3>
Answer: 768</h3>
======================================================
Explanation:
To go from gallons to fluid ounces (abbreviation fl oz), we multiply by 128
For example, 2 gallons becomes 2*128 = 256 fl oz as shown in the table.
Another example: 3 gallons = 3*128 = 384 fl oz.
Therefore, 6 gallons would be 6*128 = <u>768</u> fl oz.
To go in reverse, from fl oz to gallons, we divide by 128.
Answer:
x=45
Step-by-step explanation:
2x-56=34
Add 56 to both sides
2x-56+56=34+56
Simplify;
2x=90
Divide both sides by 2
2x/2=90/2
Simplify;
x=45
