Answer:

Step-by-step explanation:

Substitution method:

y= -2x + 2

x - 2y = 6

so y = (-2x + 2)

Substitute into y

Hence x - 2y = 6 is:

x + 2x +2 = 6 (+2x because there was - in the equations so -×- = +)

3x + 2=6

Then bring 2 to the other side so

3x = 6-2

3x = 4

x = 3/4 or 0.75

To find y :

y= (-2 × 3/4) + 2

y = -1.5 +2

y = 0.5

That's all I can do for now!

Four numbers 1-6 you roll a six-sided die whose sides are numbered from 1 through 6. Find the probability of rolling the followi

mel-nik [20]

Answer:

Since half of the numbers are even, 2, 4, 6

P(even) = 3/6 = 1/2

Multiple of 3 are 3 and 6:

P(multiple of 3) = 2/6 = 1/3

The numbers ≤ 4 are: 1, 2, 3, 4

P(≤4) = 4/6 = 2/3

Prime numbers are 2, 3, 5

P(prime) = 3/6 = 1/2

Numbers > 1 are 2, 3, 4, 5, 6

P(>1) = 5/6

A four, there is one option

P(4) = 1/6

If arctan(3/5)=K Tan(k)=?

hichkok12 [17]

$arctan(x)=y$

this function is the inverse function of tan...

$arctan(x)=tan^{-1}(x)$

then...

$x=tan(y)$

in this case

$arctan(\frac{3}{5})=K$

$\frac{3}{5}=tan(K)$

$\boxed{\boxed{tan(K)=\frac{3}{5}}}$

What are the steps to solving 7(x+2)=91 X=11

Mariulka [41]

Answer:

Below.

Step-by-step explanation:

7(x + 2) = 91

Distribute the 7 over the parentheses:

7x + 14 = 91

Subtract 14 from both sides of the equation:

7x = 91 - 14

7x = 77

x = 77/7 = 11.
