Answer:
3.9
Step-by-step explanation:
8 is rounded up because of 7
Graph A is a linear function, while Graph B is an exponential funtion.
The negative in front of the second bracket means that it's times by -1 so each of their signs switches:
3m^2+2n-m^2-2n
Add like terms
2m^2
the 2n cancels out
Step-by-step explanation:
Taking the first coordinate point (3,16.5)
where x= 3 and y= 16.5



optionB
(-2,5)(9,-6)
slope(m) = (-6-5) / (9 - (-2) = -11/11 = -1
y = mx + b
slope(m) = -1
(-2,5)...x = -2 and y = 5
now we sub and solve for b, the y int
5 = -1(-2) + b
5 = 2 + b
5 - 2 = b
3 = b
so ur equation in slope intercept form is : y = -x + 3
