Find the difference between the X and Y values goven:

10 - 1 = 9

12 - 3 = 9

15 - 6 = 9

The difference is 9, so the rule is subtracting 9 from the x value:

y = x -9

Now find Y when x is 20:

y = 20-9

y = 11

PLEASE HELP , TRYING TO BE ON HONOR ROLL !

Option A

The solution is $(0, \frac{-1}{4})$

Solution:

Given system of equations are:

3x + 6y = 1 ------ eqn 1

x - 4y = 1 ------ eqn 2

We have to find solution to system of equations

We can use substitution method

From eqn 2,

x = 1 + 4y -------- eqn 3

Substitute eqn 3 in eqn 1

3(1 + 4y) + 6y = 1

3 + 12y + 6y = 1

18y = 1 - 3

18y = -2

Divide both sides by 18

$y = \frac{-2}{18}\\\\y = \frac{-1}{4}$

Substitute the above value of y in eqn 3

$x = 1 + 4 \times \frac{-1}{4}\\\\x = 1-1\\\\x = 0$

Thus solution is $(0, \frac{-1}{4})$

Help me, I don't understand how to do it.

Levart [38]

Answer:

Aplha=105

Step-by-step explanation:

The perpendicular looks like double the base hence that angle is 30 and the other triangle have equal perpendicular and base, that angle is 45. So alpha+30+45=180, alpha=105
