Answer:
A. y ≤ 1/2x + 2
Step-by-step explanation:
Well look at the graph,
It is a solid line with it shaded down,
meaning it is y ≤,
So we can cross out B. and D.
So the y intercept is 2, we know this because the y intercept is the point on the line that touches the y axis.
now the slope can be found by seeing how far away each points are from each other,
Hence, the answer is A. y ≤ 1/2x + 2
Answer:
P and Q are two points on the line x-y+1=0 and are at a distant of 5 units from the origin. Find the area of triangle POQ.
Step-by-step explanation:
P and Q are the intersection points of
x-y+1 = 0 and the circle x^2 + y^2 = 25
sub y = x+1 into the circle
x^2 + (x+1)^2 = 25
x^2 + x^2 + 2x + 1 - 25 = 0
x^2 + x - 12 = 0
(x+4)(x-3) = 0
x = 3 or x = -4
y = 4 or y = -3
so P(3,4) and Q(-4,3) are our two points
Height of triangle.
h = |0 - 0 + 1|/√2 = 1/√2
PQ = √( (-7)^2 + 1^2) = √50 = 5√2
area POQ = (1/2)(1/√2)(5√2) = 5/2 square units

Answer:
14.25 Hours ( 14 Hours and 15 Minutes)
Step-by-step explanation:
Monday = 7 Hours and 25 Minutes
Tuesday = 6 Hours and 50 Minutes
First, Let's add 7 and 6 which is 13 Hours
Then 25 + 50 Minutes = 75 Minutes Which is also 1 Hours and 15 Minutes.
1 Hour = 60 Minutes
Hence, 75 - 60 = 15
Therefore it 1 Hours and 15 Minutes...
Next, 13 Hours + 1 Hours and 15 Minutes =
14 Hours and 15 Minutes..
thus, 14 Hours and 15 Minutes which is also 14.25 Hour is the average number of hours she spent in school.

Answer:
<h2>
$2</h2>
Step-by-step explanation:
Lets see how much money she spent first.
$50 - $26 = $24
Now that we know she spent $24 we can divide 24 by twelve which will tell us how much each ride costs
24 / 12 = 2
She spent $2 on each ride
