Given 2x - 9y - 12 = 0, express 5x - 4y + 7 = 0 in terms of x only

olga2289 [7]

Answer:

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

Step-by-step explanation:

Based on 2x - 9y - 12 = 0

-9y = 12 - 2x

9y = -12 + 2x

y = $-1\frac{1}{3} + \frac{2}{9} x$

Therefore...

5x - 4y + 7 = 0

5x - 4( $-1\frac{1}{3} + \frac{2}{9} x$ ) + 7 = 0

5x + $5\frac{1}{3}$ - $\frac{8}{9} x$ + 7 = 0

$4 \frac{1}{9}x$ + $12\frac{1}{3}$ = 0

Match the reasons with the statements in the proof if the last line of the proof would be 6. ∠1 and ∠7 are supplementary by defi

Alecsey [184]

Answer:

Given : s||t

Exterior sides in opposite rays : ∠5 and ∠7 are supplementary

Definition of supplementary angles : m∠5 + m∠7 = 180°

If lines are ||, corresponding angles are equal : m∠1 = m∠5

Substitution : m∠1 + m∠7 = 180°

Find the slope of the line that passes through (9, 6) and (4, 5).

boyakko [2]

Answer:

slope = $\frac{1}{5}$

Step-by-step explanation:

calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (9, 6 ) and (x₂, y₂ ) = (4, 5 )

m = $\frac{5-6}{4-9}$ = $\frac{-1}{-5}$ = $\frac{1}{5}$
