Answer:

C

Step-by-step explanation:

Subtract like-terms. -2y is the only variable that has a y and is therefore unaffected. 8x - x - x = 6x.

--- > 6x - 2y

Answer:

*Replace each "x" with the required numbers .

1) g (14) ; Ans;

g(x) = 2x \\ g(14) = 2(14)  \\ g(14)= 28

___o_o___

2) f (-8) ; Ans;

f(x) = x + 3 \\ f( - 8) =  - 8 + 3 \\ f( - 8) =  - 5

___o_o___

3) j (3) ; Ans;

j(x) = ( - 1)^{x + 2}  \\ j(3) =  {( - 1)}^{3 + 2}  \\ j(3) =  {( - 1)}^{5}  \\ j(3) =  - 1

___o_o___

4) h (4) ; Ans;

h(x) =  {3}^{x}  \\ h(4) =  {3}^{4}  \\ h(4) = 81

___o_o___

5) f (2.8) ; Ans;

f(x) = x + 3 \\ f(2.8) = 2.8 + 3 \\ f(2.8) = 5.8

___o_o___

6) j(-5) ; Ans;

j(x) =  {( - 1)}^{x + 2}  \\ j( - 5) =  {( - 1)}^{ - 5 + 2}  \\ j( - 5) =  {( - 1)}^{ - 3}  \\  \\ j( - 5) =  \frac{1}{ {( - 1)}^{3} }  \\  \\ j( - 5) =   \frac{1}{ - 1}  \\  \\ j( - 5) =  - 1

___o_o___

7) g(3/4); Ans;

g(x) = 2x \\  \\ g( \frac{3}{4} ) = 2( \frac{3}{4} ) \\  \\ g( \frac{3}{4} ) =  \frac{3}{2}  \\  \\ g( \frac{3}{4} ) = 1.5

___o_o__

8) [h(6.2)]² ; Ans;

h(x) =  {3}^{x}  \\ h(6.2) =  {3}^{6.2} \\ h(6.2) = 908.13785497  \\  \\  {(h(6.2))}^{2}  =  ({3}^{6.2})^{2}  \\   {(h(6.2))}^{2}  = 824714.36364715

___o_o___

9) j(2) + g(-3) ; Ans;

j(x) =  {( - 1)}^{x + 2}  \\ j(2) =  {( - 1)}^{2 + 2}  \\ j(2) =  {( - 1)}^{4}  \\ j(2) = 1 \\  \\ g(x) = 2x \\ g( - 3) = 2( - 3) \\ g( - 3) =  - 6 \\  \\  \\ j(x) + g(x) \\ j(2) + g( - 3)  \\ 1 + ( - 6) \\ 1 - 6  \\ j(2) + g( - 3) =  - 5

___o_o___

10) h(1) - f(-10) ; Ans;

h(x) =  {3}^{x}  \\ h(1) =  {3}^{1}  \\ h(1) = 3 \\  \\ f(x) = x + 3\\  f( - 10) =  - 10 + 3 \\ f( - 10) =  - 7 \\  \\  \\ h(x) - f(x) \\ h(1) - f( - 10) \\ 3 - ( - 7) \\ 3 + 7 \\  = 10 \\ h(1) - f( - 10) = 10

___________o____o__________

**We look at the table. If f(4) or f(-2) is required, it came from f(x) by substitution each x with the required numbers, and the result is in the table f(x) .

***But if he says that f(x) is equal to a number, he means the resulting table f(x) and asks for the "x" that you take from the table "x" .

<u>Table (1) Ans;</u>

f(4) = <u> –3</u>

f(-2) = <u>– 6</u>

If f(x)= -3 ,then x = <u>4</u>

If f(x) = 1 , then x = <u>3</u>

___o_o___

<u>Table (2) Ans; </u>

f(4) = <u>–7</u>

f(-2) = <u>1</u>

If f(x)= -3 ,then x = <u>0</u>

If f(x) = 1 , then x = <u>- 2</u>

___o_o____

<u>Table (3)Ans;</u>

f(4) = <u>7</u>

f(-2) = <u>3</u>

If f(x)= -3 ,then x = <u>6</u>

If f(x) = 1 , then x = <u>0</u>

PLISSSS HELP 20 POINTS
alina1380 [7]

Answer:

x=8

Step-by-step explanation:

Because you are solving for x, you want to cancel out the y terms. You can do this by multiplying the entire equations by numbers that will make the y terms have equal numbers but opposite signs.

2(2x-5y=1)

5(-3x+2y=-18)

This turns into

4x-10y=2

-15x+10y=-90

The y terms cancel out, and the other terms can be added together.

-11x=-88

x=8
