Answer:
Change the equation to slope intercept form.
(y= 1.2x + 2.2) or (b= 1.2a + 2.2)
Then shade above the line.
Step-by-step explanation:
Let's say A is "x", and B is "y."
Change the equation to slope intercept form.
120x + 100y = 220.
(Move 120x to the other side of the equation by subtracting 120x from both sides)
100y= -120x +220
(Divide 100y by 100 to remove it from Y, divide the entire right side of the equation by 100)
y= -120x/100 + 220/100
y <= 1.2x + 2.2 -> (b= 1.2a + 2.2)
The new equation is much easier to graph.
THEN, Plot the new equation, since the sign is <= (greater than or equal to)
Make a solid line.
Then shade above the line whatever color necessary, since the sign is also "greater than"
The distance between the friends at the end of one hour can be found from the Pythagorean theorem to be
.. d = √(40^2 +35^2) = √2825 = 5√113 ≈ 53.15 . . . . miles
Since the friends are continuing in the same directions at the same speeds, their distance apart will increase by this amount each hour.
distance = t*5√113 . . . . miles after t hours
$125-$81.25 =$43.75 so that is how much was saved. Now figure what percentage $43.75 is of $125. so $43.75÷$125=.35 and changing to % the discount is 35%
Okay what do you need help with?
Answer:
Step-by-step explanation:
x->5
y->2
x*5+y*2=60
if x=10——> y=5 ——> 50+10=60
if x=8——> y=10——> 40+20=60
if x=6——> y=15 ——> 30+30=60
if x=4——> y=20 ——> 20+40=60
if x=2——> y=25 ——> 10+50=60
