Which equation represents the line that passes through the point (4, -5) and is perpendicular to the line x + 2y = 5?

Lerok [7]

Answer:

y = 2x - 13

Step-by-step explanation:

Equation of a line is y = mx + c, m is the gradient and c is the intercept

The line passes through points 4 and -5, x is 4 and y is -5

-5 = 4m + c

When two lines are perpendicular, the products of their gradients are equal to -1, m1 * m2 = -1

x + 2y = 5

2y = -x + 5

y = (-1/2 * x) + 5

therefore m = -1/2

m1 * m2 = -1

m * -1/2 = -1

-m = -2 , therefore m = 2

-5 = 4 * 2 + c

c = -5 - 8, which is -13

Therefore the equation for the line is

y = 2x - 13

If a:b =2:3 write b as a fraction of a

Hatshy [7]

Answer:

given ,

$\fbox{a:b = 2:3}$

According to Question ,

we've to write b as a fraction of a.

thus , we know that

$a:b = \frac{a}{b} \\ \\ \dashrightarrow{2:3 = \frac{2}{3} }$

now to represent b as a fraction of a ,

we'll have to consider the ratio as b : a

which means ,

$b:a = inverse \: of \: a:b \\ \dashrightarrow{ b:a = \frac{b}{a} = \frac{3}{2} }$
