What is the domain and range please?

Answers

Answer 1

Step-by-step explanation:

If c varies diráctly as (1 + 1) and c= 8, when r = 3, calculate the value ofr when c= 20.
(4marks)

Answers

c = k(r + 1)

8 = k(3 + 1)

8 = 4k

8/4 = k

2 = k

c=2(r + 1)

When c = 20, then

20 = 2(r + 1)

20 = 2r + 2

20 - 2 = 2r

18 = 2r

18/2 = r

9 = r

Therefore, the value of r is 9 when c is 20.

Conditional Statement: If two lines are parallel, then they do not intersect. Converse: If two lines do not intersect, then they are parallel. Inverse: If two lines are not parallel, then they intersect. Contrapositive: If two lines intersect, then they are not parallel. Which statements are true? A) Converse and Inverse B) Inverse and Contrapositive C) Conditional Statement and Converse D) Conditional Statement and Contrapositive

Answers

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.

Two or more lines which have no intersections but are not parallel, known as skew lines.

Option D is correct.

Conditional Statement: If two lines are parallel, then they do not intersect.

Converse: If two lines do not intersect, then they are parallel.

Inverse: If two lines are not parallel, then they intersect

Contrapositive: If two lines intersect, then they are not parallel.

Thus, option (D) Conditional Statement and Contrapositive , is correct.

Converse and Inverse are false because skew lines are a type of lines which are neither parallel nor intersecting in 3D

Answers

Answer:

17 years old.

Step-by-step explanation:

sisters age:5

5×3+2=17.

Answer:

Liza is 17 years old.

Step-by-step explanation:

Ley 'x' be the age of Liza's younger sister

As Liza’s age is two more than thrice the age of her younger sister

so the equation of Liza's age will be:

Liza's age = 3x+2

As x = 5 years is Liza's younger sister age

Liza's age = 3(5)+2

= 15+2

= 17 years

Therefore, Liza is 17 years old.

Answers

Answer:

2.3=v+0.47v=

We move all terms to the left:

2.3-(v+0.47v)=0

We add all the numbers together, and all the variables

We get rid of parentheses

-1.47v+2.3=0

We move all terms containing v to the left, all other terms to the right

-1.47v=-2.3

v=-2.3/-1.47

v=1+0.83/1.47

Solve this equation.
24 + 0.44x = 19 + 1.69x

Answers

Answer:

x = 4

Step-by-step explanation:

24 + 0.44x = 19 + 1.69x

24 + 0.44x - 1.69x = 19

-1.25x = 19 - 24

-1.25x = -5

x = 4

Step-by-step explanation:

24 + 0.44x = 19 + 1.69x

24 - 19 = 1.69x - 0.44x

5 = 1.25x

1.25x = 5

x = 35 y = 82

Step-by-step explanation:

all triangles add up to 180

the tick mark shows that 2x = y - 12

2x + 2x + 40 = 180

4x + 40 = 180

4x = 140

x = 35

y - 12 + y - 12 + 40 = 180

2y - 24 + 40 = 180

2y + 16 = 180

2y = 164

y = 82

Check:

40 + 2(35) + (82 - 12) = 180
