Step-by-step explanation:
First term = T(1) is obtained by plugging n = 1 into the formula,
thus First term = 1^2 - 4 = 1 - 4
= 3 (answer)
Answer:
y = -4x
Step-by-step explanation:
Find the slope (m) and the y-intercept (b) of the line. Thereafter, substitute the value of each into y = mx + b to get the equation of the line.
✔️Find the slope (m) using two points on the line, (-2, 8) and (0, 0):
Slope (m) = change in y/change in x
m = (0 - 8)/(0 - (-2))
m = -8/2
m = -4
✔️Find y-intercept (b):
Y-intercept = 0, this is where the line intercepts the y-axis.
b = 0
✔️Substitute m = -4 and b = 0 into y = mx + b:
y = -4x + 0
y = -4x

Step-by-step explanation:
minus 2 from each side in order to isolate T with the coefficient. To get rid of the coefficient multiply to get 1 which is 5 in this case. Then the answer will be 75

let c=rate of the current
6/(4+c)+6/(4-c)=8
(24-6c+24+6c)/(16-c²)=8
