Answer:
(-3/7, 0)
Step-by-step explanation:
7x=2y-3
To find the x intercept, set y = 0 and solve for x
7x = 0-3
7x = -3
Divide each side by 7
7x/7 = -3/7
x = -3/7
The x intercept is
(-3/7, 0)
Answer:
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = 
.
In the equation you'd write that as r = 
which can be simplified to 
.
You end up with 
and you simplify this by doing 
, ending with the result of 
.
(I also got this answer right on the test.)
Answer:
22 1/2
Step-by-step explanation:
1/4×6=1 1/2
3×7=21
21+1 1/2=22 1/2
Distance between two points is
Root of X2 - X1 squared + Y2 - Y1 squared
So here X2 is 0 X1 is 0 as the origin is 0,0
Root of Y2-Y1 squared is what we are left with
Root of -2- -3 squared
Root of 1 squared
Root of 1
Which is 1
Distance is 1
