1. equation A is multiplied by -2, yah, right form
turns to -2y=-30+4z
2. wrong, yo didn't distribute the -2 at all, it just dissaperaed, who taught that student how to do math?
after this, all steps are wrong because step 2 is wrong
error in step 2
Step-by-step explanation:
the notation f(-2) indicates that you will substitute x for the value -2.
f(-2) = 6 ( 8 - (-2) ) +5 = 65
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
Answer and Step-by-step explanation:
-3(x + 5) > 12
Divide both sides by -3, then flip the sign.
x + 5 <em><</em> -4
Now subtract 5 from both sides.
x < -9
<u>x < -9 is the answer.</u>
