Answer:

A

Step-by-step explanation:

It has a slope of 1/3 and is the only one that passes through (3,2).

Answer: Number of children  = 168

Number of adults = 120

Step-by-step explanation:

Let x = Number of children and y = Number of adults

As per given,

x+y=288          (i)

2.25x+6.80y =1194       (ii)

Multiply 2.25 on both sides in (i)

2.25x+2.25y= 648       (iii)

Eliminate (iii) from (ii)

4.55y=546

[tex]\Rightarrow y=\dfrac{546}{4.55}\\\\\Rightarrow\ y=120[/tex]

Put y= 120 in (i)

x+120=288

⇒ x=288-120

⇒ x= 168

Hence, Number of children  = 168

Number of adults = 120

Answer:

C

Step-by-step explanation:

Answer:

6x+y=-8 because it will be y=-6x-8 having same slope with the line given

Answer:

Step-by-step explanation:

This is a trick. Since it's y=4. there is no slope, the slope is 0

Answer:

The Cheetah's initial speed is 19.4 miles per hour

Step-by-step explanation:

Since the Cheetah is initially running and then gradually increases its speed by 50.6 miles per hour to reach a top speed of 70 miles per hour, let the Cheetah's initial speed be u.

Also, let the increase in the Cheetah's speed be Δu and let v be the Cheetah's final speed.

Now, the final speed, v = initial speed, u + change in speed, Δu

So, v = u + Δu

So, the Cheetah's initial speed is u = v - Δu

Now, v = 70 mi/h and Δu = 50.6 mi/h

Substituting v and Δu into the equation, we have

u = v - Δu

u = 70 mi/h - 50.6 mi/h

u = 19.4 mi/h

So, the Cheetah's initial speed is 19.4 miles per hour

Answer:

I think It would be B

Step-by-step explanation:

There is a∥b, Converse of the Alternate Interior Angles Theorem, which is the correct answer that would be an option (B).

Interior angles are defined as the pair of angles created on the inner side of the parallel lines and on the opposite sides of the transversal when two parallel lines are intersected by a transversal are referred to as alternate internal angles.

Given ∠4≅∠14, which lines,

If a transversal connects two parallel lines, we know that the corresponding angles and vertically opposed angles are equivalent.

Therefore,

⇒ ∠15 = ∠3 ...(i) [Corresponding angles]

⇒ ∠15 = ∠13 ...(ii) [Vertically opposite angles]

From equations (i) and (ii), we get

⇒ ∠3 = ∠13    [Alternate interior angles]

Similarly,

⇒ ∠4 = ∠14

Hence, it is proven.

Therefore, we conclude that a∥b, Converse of the Alternate Interior Angles Theorem.

Hence, the correct answer would be an option (B).

Answer:

  KM = 4

Step-by-step explanation:

The point of the segment addition postulate is that the combined length of segments laid end-to-end is the sum of their individual lengths.*

  KL +LM = KM

  (5x +1) +(3x +3) = 5x +4

  8x +4 = 5x +4 . . . .simplify

  3x = 0 . . . . . . . . . . subtract 5x+4

  x = 0 . . . . . . . . . . . divide by 3

Then the length of KM is ...

  KM = 5x +4 = 5·0 +4 = 0 +4

  KM = 4

Answer:

BC = 20

Step-by-step explanation:

If all angles are the same then all the sides are the same; therefore, BC = AC.

Set up the equations to solve for y

-y + 23 = 6y + 2; add y to both sides

23 = 7y + 2; subtract 2 from both sides

21 = 7y; divide by 7

y = 3; now use this to substitute into term for BC = 6y + 2 = 6(3) + 2 = 18+2 = 20

Answer:

The slope is the rise over run. The change in y over the change in x. Pick two points on a line and find the change. It is usually represented by m in the slope intercept form.

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Pick two points on a line and use the formula m to find the slope, which represents the rate of change.
