Answer:
slope = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
2x - 3y = 12 ( subtract 2x from both sides )
- 3y = - 2x + 12 ( divide all terms by - 3 )
y = x - 4 ← in slope- intercept form
with slope m =
Keep your mom, you only have one. But anyway;
Use the Pythagorean Theorem: A^2 + B^2 = C^2
12^2 + 21^2 = C^2
144 + 441 = C^2
585 = C^2
square root of 585 = approximately 24.2
Answer:
slope -6/5
Step-by-step explanation:
The angels in a triangle should be 180° all
85+64+30=179<180
so we should add 1° to the first one
the angels would be 86 64 30
9 and 7 will do that job for you.
9 x 7 = 63
and
9 + 7 = 16
and
9 - 7 = 2 .
