A) Find the slope, x-intercept, y-intercept of the line (L):

Black_prince [1.1K]

Answer: 2, 1.5 , -0.75

(b) $4x-3y-10=0$

Step-by-step explanation:

Given

line is $3x+4y-6=0$

Converting it into intercept form

$\Rightarrow 3x+4y=6\\\\\Rightarrow \dfrac{3x}{6}+\dfrac{4y}{6}=\dfrac{6}{6}\\\\\Rightarrow \dfrac{x}{2}+\dfrac{y}{1.5}=1$

So, the x-intercept is $2$ and y-intercept is $1.5$

The slope is given by

$-\dfrac{\frac{1}{2}}{\frac{1}{1.5}}=-0.75$

(b) the line perpendicular to the above line and passing through $(1,-2)$

The slope of the required line

$m=-\dfrac{1}{-0.75}\\\\m=\dfrac{4}{3}$

Equation of the line is given by

$\Rightarrow \dfrac{y-(-2)}{x-1}=\dfrac{4}{3}\\\\\Rightarrow 3y+6=4x-4\\\Rightarrow 4x-3y-10=0$

There are 3 times as many boys as girls. If there are 24 more boys than girls, how many children are there?

Ludmilka [50]

Answer:

There are 48 children.

Step-by-step explanation:

Given :There are 3 times as many boys as girls.

There are 24 more boys than girls,

To Find : how many children are there?

Solution:

Let the number of girls be x

Now we are given that there are 3 times as many boys as girls.

So, no. of boys = 3x

Now we are given that there are 24 more boys than girls.

So, $3x-x=24$

$2x=24$

$x=12$

So, no. of girls = 12

No. of boys = 3x = 3(12) = 36

Now the total no. of children = 12+36 = 48

Hence there are 48 children.
