Use multiple steps formula.
Bangles of a triangle have to add up to 180 and because the variables within this problem equals 9X. X has to equal 20°
X could be 6 or -2
You start at 2 on a number line and move 4 to the right and 4 to the left.
We can use elimination to solve the system:
x+2y=0 Multiply the first equation by negative 2 so we can eliminate
2x+4y=0
-2-4y=0 Add them, -2X+2X= 0, -4Y+4Y= 0
2x+4y=0
0=0
Since 0 is indeed equal to 0 you have INFINITELY MANY SOLUTIONS.
you could also put both equation in slope intercept form and see if the slopes and Y-intercept are the same.
Answer:
Step-by-step explanation:
Let the exponential function be 
.
When x=0, 
The function now becomes 
When x=1, f(1)=-5
This implies that:
Therefore the equation for the exponential function represented in the table below is
