Answers

Answer: The rate of change in the y coordinate is 75. 78 - 3= 75.

Answer:

Part a: Answer is 1/2

78 - 3/150 - 0 = 75/150

= 1/2

Part b: Answer is -1/2

3 - 78/300 - 150

= -75/150

= -1/2

Part c: No, the two rates aren’t the same, because one is positive and the other is negative.

Part d: The rate of change of the function determined by using the two pairs of coordinates is not the same. So, the function modeling the movement of the ball is a nonlinear function

Answer: As a fraction it is  145/2 and as a mixed number it is 72 1/2

Step-by-step explanation:

First write down the number like this, 72.5/1

Then multiply each number by ten like this, 72.5 x 10 = 725

And 1 x 10 = 10 and write that as a fraction like this, 725/10

Next do 725 divided by 5 = 145 and 10 divided by 5 = 2

And put that in a fraction like this 145/2

That is the fraction of 72.5%

As a mixed number you put the 72 as a whole number and 1/2 because 5 represents a half

Write in point-slope form an equation of the line that passes through the point (1,9) with a slope of -2

Y-_=_(x-_)

Answers

Answer:

y - 9 = - 2(x - 1)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b ) a point on the line

Here m = - 2 and (a, b ) = (1, 9 ) , then

y - 9 = - 2(x - 1) ← is the equation of the line

Blake has xx dimes and yy nickels. He has a minimum of 13 coins worth at most $1 combined. Solve this system of inequalities graphically and determine one possible solution.

Answers

Blake has 5 dimes and 10 nickels.

Let x represent the number of dimes and y represent the number of nickels.

Each dime is worth 10 cent ($0.1) and each nickel is worth 5 cents ($0.05).

Since he has a minimum of 13 coins, hence:

x + y ≥ 13     (1)

It is worth at most $1 combined, hence:

0.1x + 0.05y ≤ 1     (2)

From the graph, a possible solution is (5, 10).

if f(x) = 2x^ 2 + 3x,then what is f(−9)?

Answers

Answer:

f(-9) = 135

Step-by-step explanation:

Replace x with -9, and evaluate the expression.

f(x) = 2x² + 3x

f(-9) = 2(-9)² + 3(-9)

f(-9) = 2(81) - 27

f(-9) = 162 - 27

f(-9) = 135

If f(x) = â’2 8, what is f(â’1. 8)? 4 6 10 12.

Answers

Answer:

f(x) = [x] - 2 + 8

[x] is the notation for 'greatest integer function'

f(-1.8) = [-1.8] - 2 + 8 = -2 -2 + 8 = 4

The answer is 4

Step-by-step explanation:

The value of the function  f(x) = [x] - 2 + 8 when x = -1.8 is 12

Given the function f(x) =[x] - 2 + 8, we need to find f(-1.8)

To get the value of f(-1.8), we will simply substitute x = -1.8 into the function to have:

f(-1.8) = -1.8 - 2 + 8

f(-1.8) = -3.8 + 8

f(-1.8) = 11.8

Since x is in a square bracket, we will round the value up to the nearest whole number, hence;

f(-1.8) = 12

Therefore the value of the function  f(x) = [x] - 2 + 8 when x = -1.8 is 12
