Yo sup??
4x+5y=-9
y=(-4x)/5-9/5
we see that this is of the form y=mx+c
where m is the slope
therefore the slope of the line is -4/5
To find y intercept, put x=0
y=-4*0/5-9/5
y=-9/5
Therefore y intercept is -9/5
Hope this helps.
Answer: (a) 11.8
(b) 13
Step-by-step explanation:
Since George wants to put a string of lights around , it means we will have to consider the perimeter of the shape.
Perimeter of a rectangle is given by :
P = 2( L+B)
P = 2 ( 2.5 + 3.4)
P = 2 ( 5.9)
P = 11.8 meters
(b) Since he wants to put an addition to his wooden deck that is 0.6 meters longer , then the perimeter will be the perimeter of the first shape + 2(0.6). We used 2(0.6) because the two lengths of the rectangle must be considered
Therefore, we have
P = 11.8 meters + 2(0.6)
= 11. 8 + 1.2
= 13 meters
Therefore George needs 13 meters length of light
Find the change
the change is 63-21=42
42 degrees in 12 hours
we want to find xdegrees/1hour
42/12=3.5 degrees per hour
Answer:
y = -2x - 1
Step-by-step explanation:
X : Y
-2 : 3
<u>0 : -1</u>
1 : -3
3 : -7
First we have to find the y intercept we do that by looking at the table and finding what y = when x = 0
Then to find the slope we do the change in y over the change in x so when y changes by what what does x change by in this question it's when y goes down to or -2 x goes up one -2/1x = -2x
Answer:
Yes.
Step-by-step explanation:
(3x + 1)(x + 2)
= 3x^2 + 6x + x + 2
= 3x^2 + 7x + 2.
