Answer:

2x + y = 4

3x - y = 6

I + II

2x + y + 3x - y = 4 + 6

5x = 10

x = 2

2*2 + y = 4

y = 0

Answer:

5x = 10

Yields

x=2 y=0

Step-by-step explanation:

2x+y=4 3x-y=6

We want to add these equations

2x+y=4

3x-y=6

--------------

5x = 10

If we divide by 5 on each side

5x/5 = 10/5

x =2

Now we can find y

2x+y =4

2(2) +y = 4

4+y =4

Subtract 4  from each side

4-4 +y = 4-4

y =0

^DEF and ^RSQ are shown in the diagram below
lakkis [162]

Answer:

53.3 degrees

Step-by-step explanation:

∆DEF and ∆RSQ are similar. We know this, because the ratio of their corresponding sides are equal. That is:

DE corresponds to RS

EF corresponds to SQ

DF corresponds to RQ.

Also <D corresponds to <R, <E corresponds to <S, and <F corresponds to <Q.

The ratio of their corresponding sides = DE/RS = 6/3 = 2

EG/SQ = 8/4 = 2

DF/RQ = 4/2 = 2.

Since the ratio of their corresponding sides are equal, it means ∆DEF and ∆RSQ are similar.

Therefore, their corresponding angles would be equal.

Thus, m<Q = m<F

Let's find angle F

m<F = 180 - (98 + 28.7)

m<F = 53.3°

Since <F corresponds to <Q, therefore,

m<Q = 53.3°

Guys help me I really need your help​
Harlamova29_29 [7]

Answer:

a x^2/2 is a polynomial because the power of x is 2 which is a positive whole number but 2/x^2 is not a polynomial because the power of x is -2 which is negative whole number.

b.in

\sqrt{2 x}

the power if x will be

x   {}^{ \frac{1}{2} }

which is not a whole number so it is not a polynomial.

but in

\sqrt{2} x

the power if x is a positive whole number.so it is a polynomial.

c.the greatest power of variable of the term is called degree of polynomial
