Solving for y, we add 5y to both sides and subtract 4, getting 9x-4=5y. Dividing both sides by 5, we get 9x/5-4/5=y. Since the slope is 9/5 (since 9/5*x=9x/5), we multiply it by -1 and find the reciprocal of it to get -5/9 as the perpendicular slope, so -5x/9+b=y. Plugging 1 in for x and -6 in for y, we get -5*1/9+b=-6 and by adding 5/9 to both sides we get -5-4/9=b , and since in y=mx+b y and x are variables, we end up with y=-5x/9+(-5-4/9) for slope intercept form.

To get it into standard form, we need it in ay+cx=b with a, b, and c being constants. Adding 5x/9 to both sides, we end up with y+5x/9=(-5-4/9) for standard form

Write a proof to show the opposite angles of a parallelogram are congruent. Be sure to create and name the appropriate geometric
jek_recluse [69]

Answer:


Step-by-step explanation:

Let ABCD be the parallogram.

A,B,C and D are vertices in that order.

Since ABCD is a parallelogram, we get opposite sides are parallel

AB || CD

AD is a transversal making interior angles as A and D

By parallel lines properties we have A +D =180...i

Similarly since BC||AD, and AB is a transversal

Angle A+B =180...ii

We have from i and ii, Angle B = angle D

On the same grounds, as above, we can prove that

Angle A = Angle C

It follows that in a parallelogram opposite angles are equal.

5. Gaur Grandeur is a society which has a garden of length 45 5/7 m and breadth 16 3/4m. Find area of garden​
timurjin [86]

Step-by-step explanation:

Here,

given length= 45 5/7 m( mixed fraction)

= 320/7 m( simple fraction)

similar breadth= 16 3/4 m

= 67/4 m

Now,

Area= length* breadth

= 320/7 * 67/4

=5360/7 m²

How can an expression or process be determined for an arithmetic sequence?
ElenaW [278]
An aritmetic sequcne is represented as

a_n=a_1+d(n-1)

where
an=nth term
a1=first term
d=common differnce, or how much each term increases by
n=which term



example

1,3,5, etc
first term is 1
common difference is 2 because it increases by 2 each time
so the formula would be
a_n=1+2(n-1)

if we had
5,3,1
first term s 5
common difference is -2 since it goes up by -2 each time
so formula is
a_n=5-2(n-1)



hope this helps
