This table represents the number of ounces, u, a kitten grows after w, weeks.

When graphed, all of the points in the table lie on the same line.

What is the slope and y-intercept of the line?

slope=2/3, y-intercept=−0.2

slope=−3/2, y-intercept = 3

slope= 3/2, y-intercept = 3

slope= −2/3, y-intercept=−0.2

Answers

Answer 1

Y intercept is the value of y at x = 0

At x = 0, y = 3

Y intercept is 3

The rate of growth of the cat is positive, meaning thats it gains, not loses, weight.

Option C is the only correct one.

It has a positive slope, and a y intercept of 3

To solve for slope mathematically, pick two points.

(0, 3) (6,12)

(x1, y1) (x2, y2)

(x2, y2) (x1, y1)

Pick which one is x1 and y1 and x2 and y2 based on what seems easier to calculate

Slope is equal to [tex]\frac{y2-y1}{x2-x1}[/tex]

[tex]\frac{12-3}{6-0}[/tex]

9/6

slope is 3/2

Hope this helps,

Jeron

What are composite functions?

Functions which are formed by composing two or more functions in a way that one's output is another's input are called composite functions. They are also called function of functions.

We need to find the sum of composite numbers between 13 and 23.

Therefore,

14+15 = 29+16 = 45+18 = 63+20 = 83+21 = 104+22 = 126

The composite numbers between 13 and 23 are;

14, 15, 16, 18, 20, 21, and 22.

Hence, the sum of these numbers is 126.

So the correct option is D.

Write an exponential growth function to model each situation,
15. Initial value: 20
Growth factor: 1.25

Answers

Answer: f(x)=20(1.0125)^t

Step-by-step explanation:

use the formula P(1+r)^t when considering exponential growth (make it 1-r if decay)

P - principal (initial) value

r - growth rate (as a decimal! so divide by 100)

t - time (can be years, months, days, etc)

so now that we know the formula, just plug in everything you know!

P=20, r=0.0125, t=x

so the function is

20(1+0.0125)^t or 20(1.0125)^t

since we dont have a defined time, that becomes the variable for x, the one we can manipulate, so if they ask for 10 years, just replace t with 10!

Answer: I'm not 100% sure what you're asking for, but the full answer to the last question is a .25 increase or a 25% increase.

Step-by-step explanation:

First, we need to see how much it increases.

We would take 1.50, and minus 1.25 from it to get our first answer of .25.

To get the percentage of increase, we would take our .25, and times it by 100 equaling 25%.

On the last question it’s a .25 increase so it’s going to be 25% increase.

4x - 2(x - 2) = -9 + 5x - 8

Answers

Answer is x = 7

Step by step

4x -2(x - 2) = -9 +5x -8
Distribute

4x -2x +4 = -9 +5x -8
Combine

2x + 4 = 5x -17

Subtract 5x from both sides to isolate variable

2x -5x +4 = 5x -5x -17
Combine

-3x +4 = -17

Subtract 4 from both sides to combine constants

-3x +4 -4 = -17 -4
Combine

-3x = -21

Divide both sides by -3 to solve

-3/-3 x = -21/-3

x = 7
