Okay, So We Need To Solve For X, So We Can Solve The Expression:
6x - 5.
Lets Begin.
-17x - 9 = 8.
So, We First Need To Add 9 To Both Sides.
-17x = 8 + 9
8+9 = 17.
-17x = 17
Divide.
-17x/-17 = 1x = x.
So:
X = 17/-17
17/-17 = -1
So:
X = -1
Now, Plug In The Value For The Expression.
6 * (-1) - 5
6 * (-1) = -6
(-6) - 5 = -11.
So, Our Value For 6x - 5 Is -11.
E) sqrt(30)
This is a nice problem. It was helpful to read the topic at the top.
Notice that the two right triangles are similar. Their sides are in proportion.
That is the side '3' is what 'x' is in the other triangle (you need to rotate it!)
Then 'x' is similar to '10'
3/x=x/10 ---> x^2=30, x=sqrt(30)
If you are patient, you can check that for sqrt(30) pythagoras theorem works for all the triangles.

Then
Multiplying by 1 keeps it the same. A number greater than 1 would be an increase and a number below 1 would be a decrease.
The decrease is 2.7% which is written as 0.027 as a decimal.
Subtract that from 1:
1 - 0.027 = 0.973
The multiplier would be 0.973
Answer:(–4.5, –2.5)
(4.5, 6)
(1.3, 3.5)
Step-by-step explanation:
let's keep in mind that, in the II Quadrant, cosine is negative and sine, is positive.
cosine is adjacent/hypotenuse, however the hypotenuse is simply a radius unit, and thus is never negative, so in the -(2/3) the negative must be the numerator, -2.
