Step-by-step explanation:

You can put the given values for the point ((h, k) = (-5, 2)) and slope (m = -2/5) into the point-slope form of the equation for a line:

  y -k = m(x -h)

  y -2 = -2/5(x +5)

Answer:

DCE is 54°

Step-by-step explanation:

To solve this, we must come up with an equation. Since D, C, and E are each straight lines, they are each 180°. then, each line is separating the other which splits the 180 degree line into two parts. For example, E separates D, C separates E, and so on. The exterior angles are given, but the interior aren't. So:

for angle EDC: 180 - (9x - 31)

for angle CED: 180 - (4x + 33)

for angle DCE: 180 - (7x - 2)

we know that all angles in a triangle add up to 180°. So, our equation is:

180 - (9x - 31) + 180 - (4x + 33) + 180 - (7x - 2)=180.

simplify:

180 - 9x + 31 + 180 - 4x - 33 + 180 - 7x + 2=180

540 - 20x = 180

540 - 180 = 20x

360=20x

x= 18

for angle EDC: 180 - (9•18 - 31)=49°

for angle CED: 180 - (4•18 + 33)=75°

for angle DCE: 180 - (7•18 - 2)=54°

For parallel lines, gradients (slope) must be the same.

The lines given in multiple choice, no line with the same gradient/slope as line y = 3x - 2.

Step-by-step explanation:

From y = 3x - 2,

The slope = 3

Let's check slopes of lines from multiple choice:

From first line

4x + 2y = 5

2y = -4x + 5 (dived 2 both sides)

y = - 2x + 5/2

The slope = -2

Continue with remaining three equations you get slopes: -1/2, -4 and 4.

Hence no equations above represent parallel equation to y = 3x - 2

Solve for x in the figure below
5x+18
7x-14

Answers

Answer:

16 =x

Step-by-step explanation:

The angles are corresponding angles and since the lines are parallel, they are equal

5x+18 =7x-14

Subtract 5x from each side

5x+18 -5x=7x-5x-14

18 = 2x-14

Add 14 to each side

18+14 = 2x-14+14

32 = 2x

Divide by 2

32/2 = 2x/2

16 =x

Answer: x=16

Step-by-step explanation:

make it an equation: the equation 5x+18=7x-14

then, solve for x.

steps :

1. add 14 to both sides to get 5x+32=7x

2. subtract 5x to both sides to get 32=2x

3. divide both sides by 2 to get 16=x

Using what you noticed, find the measures of the four angles at point B in this second diagram. Lines AC and DF are parallel.

Answers

Answer:

The measures of the four angles at B are

m∠EBC = 34°

m∠ABH = 34°

m∠EBA = 146°

m∠CBH = 146°

Step-by-step explanation:

∵ AC // DF

∵ HG is the transversal

∴ m∠GEF = m∠EBC ⇒ corresponding angles

∵ m∠GEF = 34°

∴ m∠EBC = 34°

∵ GH intersects AC at B

∴ m∠EBC = m∠ABH ⇒ vertically opposite angles

∵ m∠EBC = 34°

m∠ABH = 34°

∵ B ∈ AC

∠EBC and ∠EBA formed a pair of linear angles

∵ The sum of the measures of the pair of linear angles is 180°

m∠EBC + m∠EBA = 180°

→ Substitute m∠EBC by 34°

∴ 34 + m∠EBA = 180

→ Subtract 34 from both sides

∵ 34 - 34 + m∠EBA = 180 - 34

m∠EBA = 146°

∠EBA and ∠CBH are vertically opposite angles

∴ m∠EBA = m∠CBH

∵ m∠EBA = 146°

m∠CBH = 146°

12x+7<−11    First, move the constant to the right. 12x < -11 - 7 Then, we can get the total value and then divide everything by 12. 12x < -18    ->   x < - 1.5

5x−8≥40    Move the constant to the right. 5x ≥ 40+8 Then, after we add the constants, we can divide both sides by 5. 5x ≥ 48     ->       x ≥ 9.6

Here is a system of equations: 7x-4y=-11
7x+4y=-59 would you rather use addition or subtraction to solve this system. Explain your reasoning.

Answers

Answer:

Addition

Step-by-step explanation:

Better to use addition since you already have a -4y and +4y. So if you add them together it will cancel out!

x = -5 and y = -6.

We can use either of the addition or subtraction as both will involve the same process of solving the equation.

We have a system of equations -

7x - 4y = - 11

7x + 4y = - 59

We have to investigate on the process of solving these equations.

What do you mean by System of Linear equations?

A system of linear equations is a collection of one or more linear equations involving the same variables.

According to the question, we have -

7x - 4y = - 11

7x + 4y = - 59

We would subtract second equation from first as follows -

7x - 4y - (7x + 4y) = - 11 - (- 59)

7x - 4y - 7x - 4y = -11 + 59

-8y = 48

y = - 6

therefore -

7x - 4y = - 11

7x - 4(- 6) = -11

7x + 24 = -11

7x = -11 - 24

7x = - 35

x = -5

Hence, x = -5 and y = -6.

We can use either of the addition or subtraction as both will involve the same process of solving the equation.

Which number is greater than the absolute value of LaTeX: -\frac{3}{8}− 3 8?

Answers

Answer:

0.5

Step-by-step explanation:

We have to find a  number which is greater than the absolute value of -3/8.

Absolute value of -3/8 = 3/8

3/8=0.375

Now, we have to find a number which is greater than 0.375

1/4=0.25

0.25 is smaller than 0.375

0.5 is greater than 0.375

also -5/8 and -1/8 are less than 0.375
