GIVING BRAINLIEST! Solve for y: 3x - y = 14 Thank you~

1 answer:

8 0

To solve y, we need to make y the only value on the left hand side of the equation:

$3x - 3x - y = 14 \\ 3x - 3x - y = 14 - 3x \\ - y = 14 - 3x \\ y = - (14 - 3x) \\ y = - 14 + 3x$
Therefore the value of y = -14+3x.

Hope it helps!

Answer:

2 and - $\frac{1}{2}$

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 )

Given

3y = 6x + 9 ( divide all terms by 3 )

y = 2x + 3 ← in slope- intercept form

with slope m = 2

(i)

Parallel lines have equal slopes, thus

the slope of line t is 2

(ii)

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{2}$ , thus

the slope of line r is - $\frac{1}{2}$

Complete the square to solve 4x2 + 24x = 4.

igomit [66]

Answer:

x = - 3 ± $\sqrt{10}$

Step-by-step explanation:

Given

4x² + 24x = 4 ( divide through by 4 )

x² + 6x = 1

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(3)x + 9 = 1 + 9

(x + 3)² = 10 ( take the square root of both sides )

x + 3 = ± $\sqrt{10}$ ( subtract 3 from both sides )

x = - 3 ± $\sqrt{10}$

2n-7/3 = 15 solve for n

WITCHER [35]

$2n- \frac{7}{3} =15$
$2n- \frac{7}{3} =15$ common denominator is 3
$3(2n- \frac{7}{3} )=3*15$ distributhing 3 through parantheses
$3*2n- \frac{3*7}{3}=3*15$
$3*2n-7=3*15$
$6n-7=45$ add7
$6n=45+7$
$6n=52$ divide by 6
$n= \frac{52}{6}$ simplify
$n=8 \frac{2}{3}$ ⇒ $\frac{26}{3}$
