First, make sure that all the variables are in one side. The first equation is gonna be x-y=3

Second, we are going to eliminate the y because it is much easier, but you can also eliminate the x

We have to add both equation because the y in the first equation is negative and in the second equation it’s positive.

We are left with 3x=9

Therefore, x=3

Last, substitute x= 3 in one of the equations

Y=6

P.O.I is (3,6)

Find the area of the parallelogram. Round to the<br> nearest tenth.
muminat

Answer:

Step-by-step explanation:

<em>Note all arguments of trigonometric functions are in degrees.</em>

<em />

Since tan(35)=4/(longer dotted leg of the triangle), the length of this longer dotted leg is thus 4/tan(35).

Since A=bh, the area is (4/tan35)(12), and you can just plug this into a calculator.

PLEASE HELP ME I WILL GIVE BRAINLIEST
Leokris [45]

Answer:

there are fourteen 4-point questions and twenty six 2-point questions.

Step-by-step explanation:

Given : A 40-question test has 108 possible points.

There are m 4-point questions and n 2-point questions.

So , equation for total number of questions in the test :

m + n = 40 | 4n + 2n = 108

Multiplying (i) by 2 , we get

2m + 2n = 80

Subtract (iii) from (ii) , we get

2m = 28

⇒ m = 28/ 2 = 14

Using value of m in (i) , we get

14 + n = 40 ⇒ n = 26

from this we get there are fourteen  4-point questions and twenty six 2-point questions.

hope this helped!
