A cyclist travels 4 miles in 15 minutes and then a further 6 miles in 25 minutes without stopping.

Tcecarenko [31]

Total distance traveled = 4 + 6 = 10 miles

Total time = 15 + 25 = 40 minutes

Speed = 10 miles ÷ 40 minutes = 0.25 mph

Write the equation of the line perpendicular to 2x+3y=9 that passes through (-2,5). Write your answer in slope-intercept form. S

Harman [31]

ANSWER

$y = \frac{3}{2} x + 8$

EXPLANATION

The line given to us has equation,

$2x + 3y = 9$

We need to write this equation in the slope intercept form to obtain,

$3y = - 2x + 9$

$\Rightarrow \: y = - \frac{2}{3}x + 3$

The slope of this line is

$m_1 = - \frac{2}{3}$
Let the slope of the perpendicular line be

$m_2$

Then
$m_1 \times m_2 = - 1$

$- \frac{2}{3} m_2= - 1$

This implies that,

$m_2 = - 1 \times - \frac{3}{2}$

$m_2 = \frac{3}{2}$

Let the equation of the perpendicular line be,

$y = mx + b$

We substitute the slope to get,

$y = \frac{3}{2} x + b$

Since this line passes through
$(-2,5)$
it must satisfy its equation.

This means that,

$5= \frac{3}{2} ( - 2)+ b$

$5 = - 3 + b$

$5 + 3 = b$

$b = 8$

Wherefore the slope-intercept form is

$y = \frac{3}{2} x + 8$

What is the value of X ?

Zielflug [23.3K]

Answer:

x = 12

Step-by-step explanation:

their the same length so plug em equal to each other

x+5 = 2x-7

add 7 to both side to get x+12 = 2x

subtract x from both side to get x = 12
