Answer:

use slope intercept form to write the equation   y=mx+b   m (slope of the line) will be the hourly fee, and b (y-intercept) will be the one-time transportation fee.

y=30x+20

to find the cost of renting a canoe for 6 hours, plug 6 into the equation replacing x

y=(30×6)+20

y=180+20=$200

Sorry, I can't graph the line, but I would number the x-axis of the coordinate plane (graph) by 1s or 2s (for the hours), and the y-axis by 20s (for the cost

Step-by-step explanation:

Answer:

b = 1.5

Step-by-step explanation:

Lets first set up the equation:

24 - 10b = 9

Okay now lets add 10b on both sides:

24 = 9 + 10b

Now let's subtract 9 from both sides so we can get the variable b by its self:

15 = 10b

Okay now we can divide each side by 10:

1.5 = b

Answer:

24-10(1.5)=9

b = 1.5

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

Exact Form:

b  =  3 /2

Decimal Form:

b =  1.5

10(1.5) = 15

24 - 15 = 9

Answer:

20%

Step-by-step explanation:

4 is 80% of 5, so all we need to do is find out what percent is left after 80%, 20%, and then that would be how much it decreased

Answer:

The equation that models the path of the ball is y = 5·x - 0.05·x²

Step-by-step explanation:

The given information are;

The distance the football landed from where it was kicked = 100 feet

The maximum height the football reached =  125 feet

The equation that models the path of the ball is that of the equation of parabola in vertex form, given as follows;

y = a·(x - h)² + k

Where;

(h, k) = The coordinate of the vertex (which is the coordinates of the highest point reached by the ball)

Therefore, taking the x-coordinate of the highest point reached by the ball as midpoint of the horizontal distance moved by the ball, we have;

The x-coordinate of the midpoint of the horizontal distance moved by the ball = (50, 0)

We have;

The coordinate of the highest point reached by the ball = (50, 125)

Therefore;

(h, k) = (50, 125)

Substituting the above values in the equation of the parabola gives;

y = a·(x - 50)² + 125

At x = 100, y = 0, which gives;

0 = a·(100 - 50)² + 125 = a·2500 + 125

0 = a·2500 + 125

a = -125/2500 = -0.05

Therefore, we have;

y = a·(x - h)² + k = y = -0.05 × (x - 50)² + 125 = -0.05·x² + 5·x - 125 + 125

y  = -0.05·x² + 5·x - 125 + 125 = -0.05·x² + 5·x

y =  -0.05·x² + 5·x

The equation that models the path of the ball is y =  -0.05·x² + 5·x.

Answer:

Well if it is rounding to the nearest 10 it is 10

but if you meant round to the nearest 10th then it is 10.7

Step-by-step explanation:

For 10 you look at the ones place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10

FOr 10.7 look at the hundredths place if it is 0-4 round down if it is 5-9 round up so for this number round down which is 10.7

Answer:

  a)  a, b

  b)  d

Step-by-step explanation:

A line with positive slope goes up to the right. The right end is higher than the left end. Lines a and b have positive slope.

__

A line with negative slope goes down to the right. The right end is lower than the left end. Line d has negative slope.

_____

Vertical line y is said to have "undefined" slope. Horizontal lines c and x have zero slope (neither positive nor negative).
