Write an equation that represents the line.
Use exact numbers.

Answer: [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.

Step-by-step explanation:

In first meet, height of best jump = 414 feet

In second meet, height of best jump = 456 feet

Increase in height = 456 feet - 414 feet

= 42 feet

The fraction of increased in height = [tex]\dfrac{\text{Change in height}}{\text{previous height}}[/tex]

[tex]=\dfrac{42}{414}\\\\=\dfrac{7}{69}[/tex]

Hence, [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.

Answer: 45

Step-by-step explanation:

[tex]a_{n} = 5 - 2(n - 1)\\a_{16} = 5-2 (16-1)\\a_{16} = 5-2 (15)\\a_{16} = 3 (15)\\a_{16} =45[/tex]

Answer:

  DJ = 48

Step-by-step explanation:

The centroid (J) divides the median into parts that have the ratio 2:1.

  DJ : JH = 2 : 1

  DJ : (DJ +JH) = 2 : (2+1)

  DJ : DH = 2 : 3

  DJ = (2/3)DH = (2/3)(72)

  DJ = 48

Answer:

C) x=2 y=-5

y=7x-19

-2x+3(7x-19)=-19

19x=38

x=2

-2(2)+3y=-19

y=-5

Answer: 10 minivans .

Step-by-step explanation:

Given: There are 35 fourth graders and 40fifth graders in the Robotics Club.

Total people = 35+40 = 75

Since each minivan can only hold 8 people.

Number of minivan required = (Total people) ÷ 8

= 75 ÷ 8

= 9.375≈ 10

Hence, the school needs to rent approx. 10 minivans .

Answer:

The answer is B, 5.

Step-by-step explanation:

3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).

12x+8 = 68

12x = 60

divide both sides by 12...

60/12 = 5.

Therefore x =5

Answer:

Second Choice.

Step-by-step explanation:

[tex]y = mx + b[/tex]

That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.

So we can cut out the first and last choice.

Then we have only two choices which are

[tex]y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3[/tex]

The second equation is called Rational Function where a variable is a denominator.

Therefore, the correct answer is second choice.

Step-by-step explanation:

Step-by-step explanation:

Slope (m) = 2

y - intercept (c) = 4

Now the equation of the line is given by

y = mx + c

y = 2x + 4

Answer:

1 to 30 seconds

Step-by-step explanation:

3 seconds increases your speed from 32 to 35 miles per hour

Hence 3 seconds = 3 miles per hour(35-32 miles)

1 second = 1 mile

The function for the increase per mile is therefore:

f(x)= 1x

Where x is number of seconds travelled on the highway

The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)

Answer:

1, 2, 5!

Step-by-step explanation:

1. Maria rode 75 miles in 2 hours and 45 minutes.

2. Travis rode 36 miles in 1 hour and 20 minutes.

5. Carl rode 22 miles in 1 hour.

Answer:

x = -5.7778

Step-by-step explanation:

1)  8x + 8 + x -2 = 48 (You multiply the -4 into both -2x and -2, thus getting rid of the brackets)

2) 9x + 6 = -48 (Add the two values of x (8x + x) and then subtract the 2 from 8  = 6)

3) 9x =-46 - 6 (Move the 6 mover, which will change its sign from a (+) to a (-6))

4) 9x = -52 (Do the expression, and you get -52)

5) x = -52 / 9 (Isolate the x, by dividing both sides by it)

6) x = -5.7778 (Round the answer)

Answer:

Correct option is (a)

Step-by-step explanation:

According to question in the triangle ΔJKL

JK = 9 and KL =4

according to the condition of triangle sum of two sides must be greater than the third side

Here sum of its two sides is 9 + 4 = 13

⇒ third side must be greater than 13 say 13.2 = JL

therefore, perimeter of triangle ΔJKL is

JK + KL + JL = 9 + 4 + 13.2 = 26.2

Therefore correct option is (a)

Answer:

12:25

Step-by-step explanation:

Número de alunos matriculados: 2.500

Número de alunos selecionados: 1.200

A proporção que representa o número total de alunos selecionados em relação ao número de alunos matriculados é dada como:

Número de alunos selecionados: Número de alunos matriculados

= 1200: 2500

= 12 : 25
