Answer:
y = - 3
Step-by-step explanation:
Given the 2 equations
6x + 11y = - 3 → (1)
4x + y = = 17 → (2)
Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x
24x + 44y = - 12 → (3)
- 24x - 6y = - 102 → (4)
add (3) and (4) term by term to eliminate x
0 + 38y = - 114
38y = - 114 ( divide both sides by 38 )
y = - 3
Explanation: In my notes you’ll see the formula for how to find slope under “Formulas”.
How to use this formula: In the first graph you have points (2,3) and (6,8)
So y2 would be 8, and y1 would be 3.
x2 would be 6, and x1 would be 2.
1. Sub points into formula
2. subtract y2 by y1
3. Subtract x2 by x1
4. Divide top by bottom
And you’ve got your slope! (Rise/run)

Answer:
E.) 1
Step-by-step explanation:
Firstly we will solve for L.H.S.
L.H.S. =
Since we know that
is the inverse of
.
So we can say that;

Now For R.H.S.

Since we can rewrite
as
.
Now we can say that the R.H.S. is;

Now we add the fraction and get;

Now according to trigonometric identity;

So, 
Here,
and
=
<em> </em>
L.H.S. = R.H.S.
Hence 
Hey there! :D
Let's keep the fraction 5/7 in mind. We should be able to reduce everything to 5/7.
15:21 (divide both by 3) you get 5:7. That is equivalent.
10 to 14. Divide both by 2. 5 to 7. That is equivalent.
The correct answer is 28/20. That is not equivalent.
I hope this helps!

Answer:
the graph is attached below
Step-by-step explanation:

LEts make a table to get the coordinates
we need to select integers between -3 and 3
x y=x^2 - 2
-2 y=(-2)^2-2=2 (-2,2)
0 y= (0)^2 - 2= -2 (0,-2)
2 y=(2)^2-2 = 2 (2,2)
Now we use the table for graphing the given equation
The graph is attached below
