Which equation shows the point-slope form of the line that passes through (3, 2) and has a slope of y plus StartFraction one-hal

inn [45]

Answer:

$y-2=3(x-3)$

Step-by-step explanation:

We want to write the equation of a line in point-slope form.

This is given by:

$y-y_1=m(x-x_1)$

We have that line passes through (3,2).

Assuming the line has a slope of m=3, then the equation in point slope form is:

$y-2=3(x-3).$

the ratio of sadia's age to her father's age is 3:6. The sum of their age is 96 .What is sadia's age

max2010maxim [7]

We have,

$a:b=3:6,a+b=96$

Introduce variable $x$ such that $a=3x,b=6x$

The sum $a+b=96$ is therefore $9x=96\implies x=10.\overline{6}$

So,

$a=3\cdot10.\overline{6}=\boxed{32}$ (sadia's age)

$b=6\cdot10.\overline{6}=\boxed{64}$ (father's age)

Hope this helps :)

If sec 50 = cosec 70, prove that 0 = 7.5°

LiRa [457]

Answer:

The proofing is given below:

Step-by-step explanation:

$Sec 5\theta = cosec 7\theta\\\\cosec (90 - 5\theta) = cosec 7\theta\\\\Now\ on\ comparision \\\\90 - 5\theta = 7\theta\\\\90 = 7\theta + 5\theta\\\\90 = 12\theta\\\\\frac{90}{12} = \theta\\\\0.75 = \theta$

Hence, it is proved
