Answer:

See below

Step-by-step explanation:

f(x) = -2x + 2

Put x = 1

f(1) = -2(1) + 2

f(1) = -2 + 2

f(1) = 0

Put x = 0

f(0) = -2(0) + 2

f(0) = 2

Put x = -1

f(-1) = -2(-1) + 2

f(-1) = +2 + 2

f(-1) = 4

Put x = 2

f(2) = -2(2) + 2

f(2) = -4 + 2

f(2) = -2

Step-by-step explanation:

5 − 3x = −7

=> 5 + 7 = 3x

=> 12 = 3x

[tex] = > x = \frac{12}{3} [/tex]

=> x = 4 (Ans)

Given :

⠀

To Find :

⠀

Solution :

[tex]\qquad \sf \: { \dashrightarrow 5 - 3x = - 7}[/tex]

⠀

Adding (–5) to both sides :

[tex]\qquad \sf \: { \dashrightarrow 5 + ( - 5) \: − 3x = −7 + ( - 5)}[/tex]

[tex]\qquad \sf \: { \dashrightarrow \: − 3x = - 12}[/tex]

⠀

Dividing both sides by 3 :

[tex]\qquad \sf \: { \dashrightarrow \dfrac{ - 3x}{3} = \dfrac{ - 12}{3} } [/tex]

[tex]\qquad \sf \: { \dashrightarrow − x = −4}[/tex]

⠀

Cancelling (–) from both sides we get :

[tex]\qquad {\pmb {\bf{ \dashrightarrow x = 4}}} \\ [/tex]

⠀

Therefore, The required value of x is 4.

Answer: Im gonna take you down like a sweet muffin.

The number of escapes, takedowns and nearfalls Anahi have is 6, 24 and 70 respectively.

escape is worth 1 point,

a takedown is worth 2 points, and

a nearfall is worth 3 points.

escape = x

takedown = y

nearfall = z

x + y + z = 100. (1)

x + 2y + 3z = 240. (2)

y = 4x. (3)

substitute (3) into both equation

x + 4x + z = 100

x + 8x + 3z = 240

5x + z = 100. (4)

9x + 3z = 240. (5)

Multiply (4) by 3

15x + 3z = 300 (6)

9x + 3z = 240. (5)

Subtract (5) from (6) to eliminate z

6x = 60

x = 60/6

x = 6

Substitute into (3)

y = 4x

y = 4(6)

y = 24

Therefore, from (1)

x + y + z = 100.

6 + 24 + z = 100

30 + z = 100

z = 100 - 30

z = 70

Answer:

x > -3.4

Step-by-step explanation:

1 < (x + 5.5) / 2

first multiply each side by 2

2 < x + 5.5

Then subtract 5.5 from each side

-3.4 < x

x has to be on the left so you switch the hole equation around to get

x > -3.4

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

Given the system of equation expressed as:

3x + y = 3

x - 2y = 4

Solve simultaneosly;

3x + y = 3 ............. 1 * 1

x - 2y = 4 ...............2 * 3

_________________________

3x + y = 3

3x - 6y = 12

Subtract

y-(6y) = 3 - 12

7y = -9

y = -9/7

Substitute y = -9/7 into the equation to get x

x - 2y = 4

x - 2(-9/7) = 4

x + 18/7 = 4

x = 4 -  18/7

x = 3/7

Since we have a unique value of x and y, it shows that the system of the equation is consistent and independent.

3x10^-2 is larger

Step-by-step explanation:

beause 10^-2 = decimal place two place to the left

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees
