Answer:
(F) True because the x-intercept is the point on the graph where the line has Y-value of zero
Step-by-step explanation:
For x-intercept, the y-coordinate must be zero, else the point doesn't lie on the X-axis but on the X-Y plane.
Hence, the last option is correct !
Answer:
equation is y = 2-x
Step-by-step explanation:
x1 = -3
y1 = 5
x2 = 4
y2 = -2
now
m(slope) = rise/run =(y2-y1)/(x2-x1) =(-2-5)/(4+3) = -7/7 = -1
so m = -1
now
y =mx + b
-2 = -1×4 + b
or, -2 = -4 +b
so, b = 2
now
y = mx+b
y = -1x + 2
or, y = 2-x
Answer:
2 and a half spoon per person (2.5)
Step-by-step explanation:
10/4=2.5
Answer:
1.8
Step-by-step explanation:
-2 1/4 x -4/5 = 9/5
= 1 4/5
= 1.8
Set up a proportion!
40 minutes / 5 holes = m minutes / 20 holes
Cross multiply.
800 = 5m
m = 160.
It will take him 160 minutes to dig 20 post holes.
Good luck Fabian!
Hope this helps
