Answer:

x = -2

Step-by-step explanation:

6(3x + 4) = 4x − 4

Distribute:

18x + 24 = 4x - 4

18x - 4x + 24 = -4

14x + 24 = -4

14x = -4 - 24

14x = -28

x = -28 / 14

x = -2

Answer:

x = - 2

Step-by-step explanation:

Given

6(3x + 4) = 4x - 4 ← distribute parenthesis on left side

18x + 24 = 4x - 4 ( subtract 4x from both sides )

14x + 24 = - 4 ( subtract 24 from both sides )

14x = - 28 ( divide both sides by 14 )

x = - 2

A science test has multiple choice questions and short answer questions. Each multiple choice question is worth 2 points and eac

Virty [35]

Answer:

Step-by-step explanation:

Let x represent the number of multiple choice questions in the science test.

Let y represent the number of short answer questions in the science test.

Each multiple choice question is worth 2 points and each short answer is worth 5 points. This means that x multiple choice questions would be worth 2x points and y short answer questions would be worth 5y points

Therefore, an equation to represent the total points possible for the test would be

2x + 5y

Answer:

c) T(−1, 3) ° Rotation,180°

Step-by-step explanation:

Explanation:-

First we will apply transformation is

Rotation of 180° then we will apply transformation is changes

(x,y) to (-x ,-y)

a)

Given vertex T( 2 ,2 )

T( 2 ,2 )→ T( -2 ,-2)

Next we will apply rule

Horizontal translation left '1' units and Vertical translation up 'd' units

T( -2 ,-2) → T¹ ( -2 -1 ,-2 +3)

The new vertex is T¹ ( -3 ,1)

b)

Given vertex U( 4 ,2 )

U( 4 ,2 )→ U( -4 ,-2)

Next we will apply rule

Horizontal translation left '1' units and Vertical translation up 'd' units

U -4 ,-2) → U¹ ( -4 -1 ,-2 +3)

The new vertex is U¹ ( -5 ,1)

c)

Given vertex R( 3 ,5 )

R( 3 ,5 )→ R( -3,-5)

Next we will apply rule

Horizontal translation left '1' units and Vertical translation up 'd' units

R( -3 ,-5) → R¹ ( -3 -1 ,-5 +3)

The new vertex is R¹ ( -4 ,-2)

d)

Given vertex S( 1 ,3 )

S( 1 ,3 )→ S( -1 ,-3)

Next we will apply rule

Horizontal translation left '1' units and Vertical translation up 'd' units

S( -1,-3) → S¹ ( -1 -1 ,-3 +3)

The new vertex is S¹ ( -2,0)

2(x + 4)2 = 20 solve by square roots

DanielleElmas [232]

Answer:

x = − 4 ± √ 10,

Step-by-step explanation:

2(x + 4)² = 20

=> 2(x + 4) (x + 4) = 20

=> 2x + 8 (x + 4) = 20

=> 2x² + 8x + 8x + 32 = 20

=> 2x² + 16x + 32 = 20

=> 2x² + 16x + 12 = 0

=> Now solve using the quadratic formula:

x = − 4 ± √ 10,

Radical form: − 4 ± √ 10,

Decimal form: -0.84, -7.16

Hope this helps!
