What are parallel lines

Answers

Answer 1

Answer:

Parallel lines are lines in the same plane that do not intersect, like lines on notebook paper.

The "in the same plane" requirement is important! Take a look at the attached image. Lines AD and DC don't intersect, but they are not in the same plane (face of the rectangular solid). We don't call those parallel, we call them skew lines.

Write the equation of the line that passes through the points (−9,−7) and (−4,4). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.

Answers

Answer:

y + 7 = 11/5(x + 9)

Step-by-step explanation:

Given points:

(-9, -7) and (-4, 4)

Find the slope:

m = (4 - (-7)) / (-4 - (-9)) = 11/5

Use one of the points and point-slope form:

y - y1 = m(x - x2)y - (-7) = 11/5(x - (-9))y + 7 = 11/5(x + 9)

Slope

m=(4+7)/-4+9m=11/5

Equation in point slope form

y-y1=m(x-x1)

y+7=11/5(x+9)

2x + 5 /3x + 7 = 3/5 find X plz

Answers

Answer:

x = -96/55

Step-by-step explanation:

Given that 2x + (5 /3)x + 7 = 3/5

Firstly, we have to multiply through out the expression by the common denominator. We can see that the denominators are 3 and 5, hence the common denominator is 15. Multiplying through by 15 gives:

2x * 15 + (5 /3)x * 15 + 7 * 15 = (3/5) * 15

30x + 25x + 105 = 9

Collect like terms:

30x + 25x = 9 - 105

55x = -96

Dividing through by 55:

x = -96/55

Answer:

f(5) = 2

Step-by-step explanation:

it says to use the function (-x+3) for when x is bigger than 2

f(x) = (-x) + 3 replace x with 5

f(5) = (-5) + 3 and f(5) = 2

Answer:

[tex]f(5)=-2[/tex]

Step-by-step explanation:

In piecewise functions, we need to find the applicable equation to use based on our value of [tex]x[/tex]. [tex]f(5)[/tex] denotes [tex]x[/tex] as 5. Since [tex]5>2[/tex], we will use the equation that corresponds to [tex]x>2[/tex], which is [tex]-x+3[/tex].

Answer:

b= 25

Step-by-step explanation:

a+b =72

a-b = 22

2a = 94

DBS(Divide Both Side) by 2

a = 47

=47 +b =72

and:

47 -b =22

subtract 47 from both sides:

b=25

What is the value of x based on the relationships in this
triangle?

Answers

Your answer is 12°

The angles in triangle always add up to 180.

You can set up an equation using that information:

(2x+1)+(5x+5)+90=180

Combine like terms:

7x+96=180

Subtract 96 from both sides

7x=84

Finally, divide 7 from both sides and you get

A number of two digits is increased by 54 when the digits are reversed. The ten digits is three times the unit digit. Find the number

Answers

Let n be the unknown number. We can write it as

n = 10a + b

with a and b integers between 1 and 9 (either with positive or negative sign).

Reversing the digits gives another number

m = 10b + a

The first number is increased by 54 when the digits are reversed, which means

m = n + 54 → 10b + a = 10a + b + 54 → 9b - 9a = 54 → b - a = 6

The digit in the tens place of n is 3 times the digit in the ones place, so

a = 3b

Substitute this into the previous equation and solve for b :

b - a = b - 3b = -2b = 6 → b = -3

Solve for a :

a = 3b = 3(-3) = -9

Then the original number is n = 10a + b = 10(-9) + (-3) = -93

Answers

Answer:

(-4, 2)

Step-by-step explanation:

5x + 15y = 10 ---› Eqn. 1

5x - 10y = -40 ---› Eqn. 2

Subtract the eqn 2 from 1 to eliminate the x variable

Thus:

25y = 50

Divide both sides by 25

y = 50/25

y = 2

Substitute y = 2 into eqn 1.

5x + 15y = 10 ---› Eqn. 1

5x + 15(2) = 10

5x + 30 = 10

Subtract 30 from each side

5x = 10 - 30

5x = -20

Divide both sides by 5

5x/5 = -20/5

x = -4

Solution would therefore be (-4, 2)
