Write an equation of the line that is perpendicular to 3x + 9y = 7 and passes through the point (6, 4).

musickatia [10]

Hi there!

The equation of any line perpendicular to
$ax + by = c$
is
$bx - ay = c$

Therefore, in this situation, the formula of the line would be
$9x - 3y = c$

Given that the line passes through the point (6, 4) we get
$9 \times 6 - 3 \times 4 = c$
$54 - 12 = c$
$c = 44$

Therefore, the equation of the line that is perpendicular to 3x + 9y = 7 and passes through (6, 4) is
$9x - 3y = 44$

Answer:

m<1 = 45

m<2 = 135

Step-by-step explanation:

135 is across from the 135 making m1 135 and 135 plus 45 equals 180, 180 is the total for the line the other 2 angles are on.

Sara and Sam are each working on a science project in which they need to research the individual masses of the nine planets (inc

makkiz [27]

Answer:

2000 times

Step-by-step explanation:

Given

Sara:

$Mercury = 3.302 * 10^{23$

$Saturn = 5.685 * 10^{26$

Sam:

$Mercury = 3.302 * 10^{29$

$Saturn = 5.685 * 10^{32$

To determine the number of times, the mass of Saturn is greater than the mass of Mercury, we simply do the following:

$Times = \frac{Saturn}{Mercury}$

Using Sara's measurement; this gives:

$Times = \frac{5.685 * 10^{26}}{3.302 * 10^{23}}$

Apply law of indices

$Times = \frac{5.685 * 10^{26-23}}{3.302}$

$Times = \frac{5.685 * 10^3}{3.302}$

$Times = 5.685/3.302 * 10^3$

$Times = 1.72 * 10^3$

Approximate

$Times = 2 * 10^3$

$Times = 2000$
