Answer:
(2, -1)
Step-by-step explanation:
We can add the first equation by the second
(4x + 6y = 2)+(-4x + 4y = -12)=
10y=-10
we divide both sides by 10 to get
y=-1
We plug -1 in the second equation to get:
-4x+4(-1)=-12
-4x-4=-12
-4x=-8
Now, we divide both sides by -4
x=2
Hope this helps!
The entire angle is a 90 degree angle.
Subtract the entire angle from what is given to find x.
90-28=62
x=62
Answer:
The answer is 8
- 3
+ 2 -
=<u> 4 </u>
+ <u>2 </u> .
Step-by-step explanation:
Given:
8x - 3x + 2 -x = __ x + __
Now, to write a number in each blank to complete each equation so that it has the requested number of solutions.
So, to solve the equation:

So, we add the variables:

And, then subtract it:

Thus, it remains:
.
So the complete equation is:
8
- 3
+ 2 -
=<u> 4 </u>
+ <u>2 </u>
Therefore, the answer is 8
- 3
+ 2 -
=<u> 4 </u>
+ <u>2 </u> .

We have
f(x)=<span>−x</span>²<span>+ 5x + 6
g(x)=</span><span>3x − 2
we know that
f(x)=g(x)
the solution is the intersection both graphs
using a graph tool
