Answer:

x = 6

Step-by-step explanation:

Vertical angels are always equal, there fore angle A = angle B.

If angle A = angle B, and

angle A = 3x - 9 and angle B = x + 3, then

3x - 9 = x + 3

Now you can solve this like a regular inequality

Start by subtracting x by it's self then 3x to get both variables on one side.

2x - 9 = 3

Now you can add 9 to it's self and to 3 on the other side.

2x = 12

Finally, divide 2 by it's self and 12.

x = 6

Solve the system of equations. If the system has no solution, say that it is inconsistent. Graph the lines of the system.
Romashka-Z-Leto [24]

Answer:

The solution to the system of the equations will be:

x=3,\:y=1

Step-by-step explanation:

Given the system of the equations

x+y=4

x-y=2

solving the system of the equations

\begin{bmatrix}x+y=4\\ x-y=2\end{bmatrix}

x-y=2

-

\underline{x+y=4}

-2y=-2

solving

-2y=-2

Divide both sides by -2

\frac{-2y}{-2}=\frac{-2}{-2}

y=1

\mathrm{For\:}x+y=4\mathrm{\:plug\:in\:}y=1

x+1=4

x=3

Therefore, the solution to the system of the equations will be:

x=3,\:y=1

If f(x) = 6(9)^x then f(1/2) =?
Oksi-84 [34.3K]
F(x) = 6(9)^x

f(1/2) = 6(9)^(1/2)

f(1/2) = 6(9)^(0.5)

f(1/2) = 6*(9^0.5)               9^0.5 = √9 = +3 or -3.

f(1/2) = 6*3 = 18          or       6*-3 = -18

f(1/2) = 18   or   -18     

Hope this helps.

Use the area of a rectangle and the Distributive<br> Property to find each product.<br> 9 X 34
OLga [1]

Answer:

Step-by-step explanation:

Write 34 in tens and units.

34 = 30 + 4

9(30 + 4)

9 * 30 = 270

9* 4 = 36

270 + 36 = 306

After awhile if your practice enough, you can do them in your head.
