Answer:
1,1/9,2/3
Step-by-step explanation:
You keep the bottom number and just add or subract the top number
2/5+3/5= 1
8/9-7/9=1/9
3/3-1/3=2/3
The correct answer is C! Because 21/2 = 10.5 and 10.5 x 4.5 = 47.25
Answer:
Step-by-step explanation:
Lines with undefined slopes are perfectly vertical, of the form "x = ". A line with "the same x-intercept" as the given line that has an undefined slope will be the line that we want. I know that sounds confusing; we'll work through it then I'll explain it better. In order to find the x-intercep of the given line, solving it for y will make it a bit easier to "see". Therefore,
-y = -x + 1 and
y = x - 1. The x-intercept exists when y = 0, so setting y equal to 0 and solving for x:
0 = x - 1 and
1 = x. That's the x-intercept. It's also the line that we want that has an undefined slope, because "x = " lines are lines vertical lines and vertical lines have undefined slopes.
x = 1 is the line you want.
Answer:
4x+3y=5
Step-by-step explanation:
Subtract
4
x
from both sides of the equation.
3y = 5− 4x
Divide each term by 3 and simplify.
y= −4x 3+53
Rewrite in slope-intercept form.
y
=
−

The formula for finding the area of an equilateral triangle is
square root of 3 * (a^2/2)
a is the side length so in this case is 6
square root of 3 * (18)
the area is about 15.6
