Answer:
y = 4x +3
Step-by-step explanation:
The slope formula can be used to find the slope:
m = (y2 -y1)/(x2 -x1)
Using the first two lines of the table, we find the slope to be ...
m = (11 -7)/(2 -1) = 4/1 = 4
__
The y-intercept can be found from the relation ...
b = y -mx
Using the slope we found, and the first line of the table, we find the intercept to be ...
b = 7 -4(1) = 3
__
Then the equation is ...
y = mx +b . . . . . . slope-intercept form of the equation for a line
y = 4x +3
Answer:
xsquared + 8x + 12
Step-by-step explanation:
Answer:
A = P(1 + r/100)^n
A = 1000 x (1.08)^n
Step-by-step explanation:
n is the number of years, p is the principal, A is the amount.
The lamp is appreciating (increasing in value) so every year, its value is 1.08 times its value the year before.
Use the first equation to be more general, use the second equation if there isn't anything below asking you to input numbers into the equation.
Probably just use the first one.
3.939x10^-6
That should be right.
Answer:
4.6 per hour
Step-by-step explanation:
Decrease, means subtraction; 100% - 8% = 92%, or 0.92.
0.92(5) = 4.6 per hour
