Answer:

n = $\frac{9}{5}$

Step-by-step explanation:

Simplify the fraction on the right side

$\frac{n}{5}$ = $\frac{45}{75}$ = $\frac{3}{5}$ ( cross- multiply )

5n = 15 ( divide both sides by 5 )

n = 3

Start with

$\dfrac{n}{5}=\dfrac{45}{75}$

Multiply both sides by 5:

$n = \dfrac{45\cdot 5}{75} = \dfrac{45}{15} = 3$

a line passes through point (-2,5) and has a slope of 2/3 points a (x,3) and b ( -2, y) lie on the line what is the value of y a

Tomtit [17]

Answer:

The value of y is 5 , and The value of x is - 5

Step-by-step explanation:

Given as :

The line passes through point ( - 2, 5)

The slope of line is m = $\frac{2}{3}$

Equation of line is written as

y - $y_1$ = m × (x - $x_1$ )

Since line passes through line ( - 2 , 5 ) and have slope $\frac{2}{3}$

So, y - 5 = $\frac{2}{3}$ × (x + 2)

Or, 3 × ( y - 5 ) = 2 × ( x + 2 )

Or, 3 y - 15 = 2 x + 4

Or, 3 y - 2 x - 19 = 0 is the equation of line

Now points ( x , 3 ) lies on the line 3 y - 2 x - 19 = 0

So, 3 × 3 - 2 x - 19 = 0

or, 9 - 2 x - 19 = 0

or, 2 x = - 10

∴ x = - $\frac{10}{2}$

I.e x = - 5

Again points ( - 2 , y ) lies on the line 3 y - 2 x - 19 = 0

So, 3 × y + 2 × 2 - 19 = 0

Or, 3 × y + 4 -19 = 0

or, 3 y = 15

∴ y = $\frac{15}{3}$

I.e y = 5

Hence The value of y is 5 , and The value of x is - 5 . Answer

Answer:

C: ∠6 and ∠2

Step-by-step explanation:

Step 1:

∠6 = ∠9 S.S. Int. ∠'s (Same Side Interior ∠'s)

Step 2:

∠9 + ∠2 = 180° Sum of line

Step 3:

∠9 ≠ ∠2

Answer:

C: ∠6 and ∠2
