Answer:
10.
Step-by-step explanation:
AK = KB so
3x + 1 = 1/3 x + 9
3x - 1/3 x = 9 - 1 = 8
Multiply through by 3:
9x - x = 24
8x = 24
x = 3
So AK = 3(3) + 1 = 10.

Answer:
The first term is 6; the common difference in 0.8.
Step-by-step explanation:
The nth term is:
The sum of the first n terms is:
Equation 1
Equation 2
Equation 1 and Equation 2 form a system of equations in 2 unknowns.
To eliminate a_1, subtract 26 times Eq. 1 from Eq. 2.
Answer:
The first term is 6; the common difference in 0.8.
Answer:
The equation of the line is;
y = 4x - 16
Step-by-step explanation:
Here, we want to find the equation of a line that passes through the point (2,-8) and has a slope of 4
To get this equation, we are going to use the point-slope form
Thus, we have it that;
y-y1 = m(x-x1)
y -(-8) = 4(x-2)
y + 8 = 4x - 8
y = 4x -8-8
y = 4x - 16
D) 35
Use the slope formula
(y2-y1)
______
(x2-x1)
(70-35)
______= 35/1
(1 - 0)
