The ratio of boys to girls at a school dance is shown in the graph. Which equation has a greater rate of change than the rate sh

own in the graph? A graph is shown in the xy-plane. The x-axis is labeled as Number of Girls and the y-axis is labeled as Number of Boys. The values on the x-axis range from 0 to 9 in increments of 1 and the values on the y-axis range from 0 to 9 in increments of 1. A line starts from the origin, goes up, and passes through (4, 1). A. y = 1 5 x B. y = 1 7 x C. y = 2 9 x D. y = 2 3 x

Answer:

  y = 2/3x

Step-by-step explanation:

The graph shows a rise of 1 for a run of 4, so its slope is ...

  rise/run = 1/4

The equation with a greater rate of change is the one with an x-coefficient greater than 1/4. That one is ...

  y = 2/3x

marshall27 [118]

Answer:

c) 44000 miles

Step-by-step explanation:

The regression line has the following format:

y = bx + a

In which b is the slope(how much each mile costs) and a is the fixed number of miles flown.

In this problem, we have that:

a = 24000, b = 10. So

y = 10x + 24000

A person who spent $ 2000 is predicted to have flown:

This is y when x = 2000.

y = 10(2000) + 24000

y = 44000

So the correct answer is:

c) 44000 miles

Sarah buys a new bike. The total cost of the bike including taxes is $349. She pays $100 down and then agrees to pay the balance
OlgaM077 [116]

The amount of each of the 6 payments will be $41.50

Step-by-step explanation:

Given,

Cost of bike including taxes = $349

Down payment = $100

Amount left to pay = Cost of bike - Down payment

Amount left to pay = 349 - 100

Amount left to pay = $249

She agrees to pay in 6 equal payments, therefore, we will divide the total amount to pay by 6.

Amount to pay for one month = \frac{Amount\ left\ to\ pay}{No.\ of\ months}

Amount to pay for one month = \frac{249}{6} = \$41.50

The amount of each of the 6 payments will be $41.50

According to the Rational Root Theorem, which is a factor of the polynomial f(x) = 3x3 – 5x2 – 12x + 20?
Harlamova29_29 [7]

3x^3 – 5x^2 – 12x + 20

= (3x^3 – 5x^2) – (12x - 20)

= x^2(3x - 5) - 4(3x - 5)

= (3x - 5)(x^2 - 4)

= (3x - 5)(x + 2)(x - 2)


Factors: (3x - 5), (x + 2), and (x - 2)


Answer:

D.) 3x – 5
