Answers
Answer: y=5x+4
Step-by-step explanation:
Remember this
Slope-Intercept form: y=mx+b
m is the slope (5)
b is the y-intercept (4)
So your equation is
y=5x+4
Answer:
y = 5x + 4
Step-by-step explanation:
y - 4 = 5(x - 0)
That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -

Calculate the sum of the first n terms of the arithmetic progression (an)
a) a, = -4; d = 2; n = 16
please help me
Answers
Answer:
n²-5n
Step-by-step explanation:
The sum of the nth term is expressed as;
Sn =n/2[2a+(n-1)d]
Given
a, = -4; d = 2; n = 16
Sn = n/2[2(-4)+(n-1)2]
Sn =n/2[-8+2n-2]
Sn = n/2[2n-10]
Hence the sum of the nth term is 2n²-10n/2
2n(n-5)/2
= n(n-5)
= n²-5n
The sum of the nth term is n²-5n
