Answer:

x = - 2

y = 6

Step-by-step explanation:

The best way to do this is to put - 3x in for y in the second equation.

4x - 2(-3x) = - 20 Watch the signs. You have 2 minus signs.

4x - - 6x = -20 Change - - 6x to 6x

4x + 6x = - 20 Add

10x = - 20 Divide by 10

x = -20/10

x = - 2

============================

Find y

y = - 3x

y = -3 * -2

y = 6

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d

ahrayia [7]

Answer: Option b.

Step-by-step explanation:

1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

$y=f(x+3)=(x+3)^{3}$ (The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

$y=f(x+3)-2=(x+3)^{3}-2$ (The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in the option b.

Answer:

B. Angle Addition Postulate; Subtraction Property of Equality

Step-by-step explanation:

<u>Given:</u>

$m\angle PQR=x+7\\ \\m\angle SQR=x+3\\ \\m\angle PQR+m\angle SQR=m\angle PQS=100^{\circ}$

<u>Find:</u> x

<u>Solution:</u>

1. $m\angle PQR+m\angle SQR=m\angle PQS$ - Angle Addition Postulate

2. $x+7+x+3=100$ - Substitution Property

3. $2x+10=100$ - Simplify

4. $2x=90$ - Subtraction Property of Equality

5. $x=45$ - Division Property of Equality
