Answer:

y = -7/5x -8

Step-by-step explanation:

Equation of straight line in point slope form is given by

y = mx +c

where m is the slope of line and

c is y intercept .

_______________________________

Given equation of line u is

y = 5/7 x -6

it is in slope intercept form

thus,

slope = 5/7

we have to find equation of line V which is perpendicular to given line.

we know that product of two perpendicular lines is -1

m1 *m2 = -1

we have m1 = 5/7

thus

5/7*m2 = -1

m2 = -7/5

Thus,

slope of line v is -7/5

let the equation of line V be

y = mx + c

m = -7/5

thus,

equation of line V can be written as

y -7/5 x + c

this line pass passes through point(-10,6)

putting x = -10 and y = 6

we have

6 = -7/5*-10 +c

6 = 14+c

c= 6-14 = -8

Thus,

equation of line in slope intercept form is y = -7/5x -8

3 letters without replacement 4 letters A B C D how many ways can this be done if the order of the choices matters
Veseljchak [2.6K]

Answer:

Since the order of choice matters, we will permute the values.                       a bit more explanation for this:

If the order of choice did NOT matter, ABC and BCA will be counted as one since order of choice does NOT matter

Since order of choice does matter, ABC , BCA and CAB are all different possibilities for the arrangement of the same 3 letters

Since we have 3 slots:

___  ___ ___

Now, for the first slot. You can out either one if the 4 alphabets in the first slot since no slot has been used as of now

So:

_<u>4</u>_ ___ ___

**Keep in mind that the 4 is the possible number of values this slot can have**

Now that one slot has been used, one of the 4 alphabets has been used and since we are not allowed to repeat the same alphabets, we are left with  3 more alphabets

we can put any one of the 3 alphabets in this second slot, Hence:

_<u>4</u>_ <u>_3_</u> ___

Now that 2 of the 4 alphabets have been used, we are left with only 2 alphabets, so there are only 2 possible alphabets for slot 3

Therefore:

_<u>4</u>_ _<u>3</u>_ _<u>2</u>_

Now that we know the possible alphabets for all 3 slots, we will multiply them with each other to get the total possible number of 3 - alphabet words we can make with 4 alphabets

Total possible words = 4 * 3 * 2

Total possible words = 24

We could've used the formula for Permutation as well

X – 2y = 1<br> 2x + 3y = -12
lions [1.4K]

Answer:

x= -3

y= -2

From the first one, if you add 2y to both sides you can plug that into the second one and solve for y. Then, plug y to the first one and solve for x.

Could you please provide the answer as well as explain it, I will be very grateful...

Hello,

There is a mistake: it is 816 cm² !!! (an area)

length are multiplied by 2,
so area are mutiplied by 2²=4
Area B=816*4=3264 (cm²)
