Answer:
the slope-intercept equation of a line that passes through the coordinate (-4,5) and (8,-1) is
Step-by-step explanation:
1) Apply the slope formula; y^2 - y^1 divided by x^2 - x^1
y^2 is -1
y^1 is 5
x^2 is 8
x^1 is -4
-1 - 5 = -6
8 - (-4) = 12
-6/12 is -1/2 or -0.5
2) To find the y-intercept, hoose either of the coordinates and replace y, m, and x in the y= mx+b formula.
5= -0.5(-4) + b
5= 2 + b
3= b
Answer:
Step-by-step explanation:
Let
x ----> the number of 1/3 in that are in 5/6 in
To find out the number of 1/3 in that are in 5/6 in, divide 5/6 by 1/3
so
Multiply in cross
Convert to mixed number
1/4 of 1 minute would be 1/4 * 60(seconds in a minute)
so that would be 60/4=15 seconds.
Answer:
∠x = 117°
Step-by-step explanation:
supplement of ∠101° = 79°
all triangle interior angles add up to 180°
180° - 79° - 38° = 63°
the supplementary angle to 63° is 117°
