Answer:
(c) y = -3x +6
Step-by-step explanation:
The equation can be written in slope-intercept form when we know the slope and the y-intercept.
<h3>Slope-intercept form</h3>
The slope-intercept form of the equation of a line is ...
y = mx +b . . . . . . where m is the slope and b is the y-intercept
<h3>Y-intercept</h3>
The y-intercept is the y-value where the line crosses the y-axis. It is 6. This eliminates choices A and D, leaving choices ...
- y = 3x +6 . . . . . choice B
- y = -3x +6 . . . . .choice C
<h3>Slope</h3>
The line goes down to the right. This is a negative slope, eliminating choice B.
The equation of the line is y = -3x +6.
__
<em>Additional comment</em>
The line intersects the x-axis at x=2. This means the "rise" of the line is -6 units for a "run" of 2 units. The numerical value of the slope is ...
m = rise/run = -6/2 = -3
Now, we know the parameters of the equation are m=-3, b=6, and the equation of the line is
y =-3x +6
Answer:
Yes
Step-by-step explanation:
200% is basically 2/1, and 2/1 = 2. 2 is a whole number.
Given:
Dimensions of rectangular garden are (-7x-3) feet by (9x+2) feet.
Cost of oak fencing = $11 per foot
To find:
The cost of total oak fencing around her garden.
Solution:
Let,
Length of the garden, l = (-7x-3) feet
Width of the garden, w = (9x+2) feet
So, the perimeter of garden is (4x-2) fee.
Cost of oak fencing is $11 per foot. So, total cost is
Therefore, the total cost of oak fencing is 44x-22x.
Answer:
x = 2/9
Step-by-step explanation:
1/3^x = 27^x + 2
1/3x = 27x +2
-1/3x -1/3x
0 = 9x + 2
+2 +2
2 = 9x
/9 /9
2/9 = x
