Answer:

y = -2x + 5

Step-by-step explanation:

A(4, -3) ; B(2, 1)

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$= \frac{1-[-3]}{2-4}\\\\= \frac{1+3}{2-4}\\\\= \frac{4}{-2}\\\\= -2$

m = -2 ; A(4,-3)

$y - y_{1}=m(x-x_{1})\\\\y -[-3] = (-2)(x - 4)\\\\y + 3 = -2*x -4 *(-2)\\\\y + 3 = -2x + 8\\\\ y = -2x + 8 - 3 \\\\ y = -2x + 5$

Find the sum of the numbers divisible by 7 between 30 and 500

brilliants [131]

Answer:

17822

Step-by-step explanation:

The number that are divisible by 7 between 30 and 500 are as follows :

35, 42,49,.....,497

It will form an AP with first term, a = 35 and common difference, d = 7

Let there are n terms in the AP.

nth term of an AP is given by :

$a_n=a+(n-1)d$

Putting all the values,

$497=35+(n-1)7\\\\462=(n-1)7\\\\n-1=66\\\\n=67$

Now, the sum of n terms of an AP is given by :

$S_n=\dfrac{n}{2}[2a+(n-1)d]$

Putting all the values,

$S_n=\dfrac{67}{2}[2(35)+(67-1)7]\\\\S_n=17822$

Hence, the sum of the numbers that are divisible by 7 between 30 and 500 is 17822.

Step-by-step explanation:

A right triangle has 90°

Given: 15 and 20

15 + 20 = 35

90 - 35 = 55

55 is the missing angle

Round to the nearest tenth: 55 ÷ 10 = 5.5
