Answer:

y = -3/2x + 6

Step-by-step explanation:

Parallel lines have the same slope so slope is -3/2

Using (4,0)

y = mx + b

0 = -3/2(4) + b

0 = -6 + b

b = 6

so y = -3/2x + 6

In a nursery class of 18 pupils, the average is 4<img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B2%7D%20" id="TexFormula1"

Alisiya [41]

Answer:

The sum of ages of all 18 pupils in the class = 81

Step-by-step explanation:

Total number of pupil in the class = 18

Average of years in the class = $4\frac{1}{2}$

Now, $4\frac{1}{2} = 4 + \frac{1}{2} = 4 + 0.5 = 4.5$

⇒Average of sum of ages in the class = 4.05

Let us assume the sum of ages of all students in the class = m

By the formula for AVERAGE:

$\textrm{Average of n obseravtions} = \frac{\textrm{Sum of n observations}}{\textrm{n}}$

$\implies 4.5 = \frac{m}{18}$

or, m = 18 x 4.5 = 81

Hence, the sum of ages of all 18 pupils in the class = 81

What is the intersection point of the lines y - 4x + 4 and y = 2x + 1?

lora16 [44]

Answer:

$(\frac{1}{2}),(2)$

Step-by-step explanation:

Eliminate the equal sides of each equation and combine.

$-4x+4=2x+1$

Solve $-4x+4=2x+1$ for $x$ .

$x=\frac{1}{2}$

Evaluate $y$ when $x=\frac{1}{2}$ .

$y=2$

L'Hospital's Rule Lim X approaches 0 cot2x•sin6x

77julia77 [94]

$\bf \lim\limits_{x\to 0}\ cot(2x)sin(6x)\implies \lim\limits_{x\to 0}\ \cfrac{cos(2x)}{sin(2x)}sin(6x)\\\\
-----------------------------\\\\
\underline{LH}\qquad \cfrac{-2sin(2x)sin(6x)+cos(2x)6cos(6x)}{2cos(2x)}
\\\\\\
\lim\limits_{x\to 0}\ \cfrac{-2sin(2x)sin(6x)+cos(2x)6cos(6x)}{2cos(2x)}
\\\\\\
\lim\limits_{x\to 0}\ \cfrac{-0\cdot 0+1\cdot 6\cdot 1}{2\cdot 1}\implies \cfrac{6}{2}\implies 3$
