Find an equation of the line perpendicular to y=4x+5 and that passes through the point (0,-1)

iragen [17]

Answer:

y = -1/4x - 1.

Step-by-step explanation:

y = 4x + 5

The slope of this is 4 so the slope of line perpendicular to this line = -1/4.

Using the formula y - y1 = m(x - x1):

y - (-1) = -1/4(x - 0)

y + 1 = -1/4x

y = -1/4x - 1.

(3y-20)+(4x-5)+(x+y-10)+(2x+5)=360 (Angles sum of it trapezium)
3y-20+4x-5+x+y-10+2x+5=360
7x+4y=390

When a certain number is divided by 24,36 or 50 the remainder is 3 in each case.find the number

Lady bird [3.3K]

Answer:

$\color{orange}{1803}$

Step-by-step explanation:

Let the number be 'x'

Using the general formula

Divided number = (Quotient × Dividend) + Remainder

Where Quotient is an integer

When divided by 24..

x = 24P + 3

Where P is an integer

When divided by 36..

x = 30Q + 3

Where Q is an integer

When divided by 50..

x = 50R + 3

Where R is an integer

Therefore..

24P = 36Q = 50R

L.C.M of their co-oficients is 1800

$1800 \frac{P}{75} =1800 \frac{Q}{50} =1800 \frac{R}{36}$

$\frac{P}{75}=\frac{Q}{50} =\frac {R}{36}$

For smallest values for integers P, Q and R

P = 75, Q= 50 and R = 36

Substitute any of the values to find x

x = 24P + 3

x = 24(75) + 3

x = 1800 + 3

x = 1803

Hope it helps
