X=0
Y=-2

Multiply the top equation by -2 to get -2y=-8x+4

Isolate 2y on the bottom by subtracting 3x from both sides to get 2y = -4 - 3x

Add the two equations get 0=-11x so x = 0

Solve for y by plugging zero into one of the equations to get y=4(0)-2 to find the y = -2
y=4(0)-2

Write an equation in slope-intercept form of<br> the line that passes through (-6,4) and<br> (-1,2).

xz_007 [3.2K]

Answer:

Step-by-step explanation:

(-6 , 4) & (-1 , 2)

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

$= \frac{2-4}{-1-[-6]}\\\\= \frac{-2}{-1+6}\\\\= \frac{-2}{5}$

m = -2/5 & (-6 , 4)

y -y1 = m(x -x1)

$y - 4 = \frac{-2}{5}(x - [-6])\\\\y - 4 = \frac{-2}{5}(x + 6)\\\\y - 4 = \frac{-2}{5}x + 6*\frac{-2}{5}\\\\y = \frac{-2}{5}x -\frac{12}{5}+4\\\\y=\frac{-2}{5}x-\frac{12}{5}+\frac{4*5}{1*5}\\\\y=\frac{-2}{5}x-\frac{12}{5}+\frac{20}{5}\\\\y=\frac{-2}{5}x+\frac{8}{5}$

A laptop is sold for $1274 after a discount of 9%.

chubhunter [2.5K]

Answer:

SP = 1274

Discount 9%

Selling price = MP (100 - d) / 100

1274 = MP (100 - 9) / 100

1) MP = 1400

i) After 5% discount = 1400 x 0.95 = 1330

After 4% discount = 1330 x 0.96 = 1276.80
