A television and a DVD player cost a total of 1296. The cost of the television is two times the cost of the DVD player. find the

seraphim [82]

You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.

Which is an equation of a line that passes through the point (-4, 7) and is perpendicular to the line y = (1/2)x + 4

8_murik_8 [283]

Find the slope of the perpendicular line:

$y = \dfrac{1}{2} x + b$

$\text {Slope = } \dfrac{1}{2}$

$\text {Slope =} \boxed {\text{negative reciprocal}} \text { of the slope of the original line}$

$\text {Perpendicular Slope = -2}$

Form the equation:

$y = mx + b$

$y = -2x + b$

Find y-intercept given that the line passed through (-4, 7):

$y = -2x + b$

$7 = -2(-4) + b$

$7 = 8 + b$

$b = 7 - 8$

$b = -1$

Form the equation:

$y = -2x - 1$

$\boxed {\boxed {Answer: y = -2x - 1}}$
