Answer:
x≤16
Step-by-step explanation:
It is asking for the intercept.
y = x + 3 becomes y - x = 3
multiply it by two, so it becomes -2x + 2y = 6. Then add it to the other equation, and solve for y.
2x + 4y = 60
(2x + 4y) + (-2x + 2y) = 60 +6
6y = 66
y = 11
Plug in the known y into the the easiest equation.
11 = x +3
x = 8
Intercept: (8, 11)
2017 = 2 hrs x 60 mins = 120 mins
2016 = 8/11 x 120 mins = 87.27 mins
2015 = 9/12 x 120 mins = 90 mins
Therefore, Fatema ran the fastest in 2016.
The answer is b) 89.95in.
To work out the perimeter P of a semicircle you need to use the formula for the circumference of a circle divided by two plus the diameter.
P =
d/2 + d
= 3.14*35/2 + 35
=109.9/2 + 35
= 54.95 + 35
= 89.95in
Answer:
1st graph is Y=1x+0
2nd Graph is Y=-2/1x + 0
Step-by-step explanation:
Your slope is 1 for the 1st graph
Your slope is -2/1 for the second graph
