Answer:
Step-by-step explanation:
We are going to do a replacement of x for a second equation
So instead
in the place of x we are putting 12-y from the first equation, so
To leave the brackets we need to do multiplication
Which is
How to determine x? From the first equation:
If the x +y = 12 then the x = 12-y so x = 12-7 = 5
We should write solution as a pair:
The length of the sky lift is 3.387.05 ft
Step-by-step explanation;
By an online search, i found that the sky lift
rises at an angle of 20.75 degrees.
Then we can think on a triangle rectangle, such
that:
One cathetus is 1200ft, this is the opposite
cathetus to the angle of 20.75°
The length of the ski lift would be the
hypotenuse of this triangle rectangle.
Then we can use the relationship:
Sin(a) = opposite cathetus/hypoteuse.
such that:
a = 20.75°
opposite cathetus=1200ft
then:
sin(20.75°) = 1200ft/hypotenuse
hypotenuse =1200ft/sin(20.759) =3.387.05 ft
The length of the sky lift is 3.387.05 ft
What i did is that i did $1.50 time 8 = $12.00 and then do $30.00-12.00=$18.00
Answer:
(2, -7)
Step-by-step explanation:
The image is the point after the transformation. So basically we want to move backwards. the transformation is (x-6, y+8) so that means we want to find when we go in reverse, or in other words (x+6, y-8) from the image (-4, 1)
(x+6, y-8)
(-4+6, 1-8)
(2, -7)
You can check by transforming this point witht he transformation properly. And just a reminder (x-6, y+8) mans left 6 and up 8
1 in 2. Each flip is independent of each other, so whether it is the 1st flip or 5th or 100th, the probability of getting tails on any one flip is 50%
