Answer:

=》n = 10

Step-by-step explanation:

here's the solution :-

=》

2(n - 9) - 1 = 1

=》

2(n - 9) = 1 + 1

=》

2(n - 9) = 2

=》

n - 9 =  \frac{2}{2}

=》

n - 9 = 1

=》

n = 1 + 9

=》

n = 10

hence, the value of n = 10

two lines intersect.One has gradient 4 and y-axis intercept 3. The other has gradient 6 and cuts the y-axis at (0,1). What is th
timurjin [86]

Answer:

(1, 7 )

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Then the equations of the 2 lines are

y = 4x + 3 → (1)

y = 6x + 1 → (2)

Substitute y = 6x + 1 into (1)

6x + 1 = 4x + 3 ( subtract 4x from both sides )

2x + 1 = 3 ( subtract 1 from both sides )

2x = 2 ( divide both sides by 2 )

x = 1

Substitute x = 1 into either of the 2 equations for corresponding value of y

Substituting into (1)

y = 4(1) + 3 = 4 + 3 = 7

Point of intersection = (1, 7 )
