The slope-intercept form given (6,-5) & perpendicular to -5x - 7y = -17.

tatuchka [14]

Answer:

$y=\dfrac{7}{5}x-\dfrac{67}{5}$

Step-by-step explanation:

Slope-intercept form of a linear equation:

$y=mx+b$

where:

m is the slope.
b is the y-intercept.

Rearrange the given equation so that it is in slope-intercept form:

$\implies -5x-7y=-17$

$\implies -7y=5x-17$

$\implies y=-\dfrac{5}{7}x+\dfrac{17}{7}$

Therefore, the slope of the given equation is -⁵/₇.

If two lines are perpendicular to each other (at right angles), the product of their slopes will be -1. Therefore, their slopes will be negative reciprocals of each other.

Therefore, the slope of the line perpendicular to the given equation is:

$\sf m=\dfrac{7}{5}$

Substitute the found slope and the given point (6, -5) into the slope-intercept formula and solve for b:

$\implies -5=\dfrac{7}{5}(6)+b$

$\implies -5=\dfrac{42}{5}+b$

$\implies b=-\dfrac{67}{5}$

Substitute the found slope and the found value of b into the slope-intercept formula to create the equation for the perpendicular line:

$\implies y=\dfrac{7}{5}x-\dfrac{67}{5}$

Ethan and his brother each sold the same number of raffle tickets they began with 42 tickets and after the sale is over and we'r

Dominik [7]

For this case, we have initially had 42 tickets.

Then Ethan and his brother sold the same amount of tickets to end up with 8.

Then, we can propose the following equation:

$42-x-y = 8$

Where x and y represent the amount of tickets sold by Ethan and his brother respectively. Since each sold the same amount, then x = y:

$42-x-x = 8\\42-2x = 8\\42-8 = 2x\\34 = 2x\\x = \frac {34} {2}\\x = 17$

Thus, each sold 17 tickets.

Answer:

Each brother sold 17 tickets
