:

7

i.e for every  

2

red balls there are  

7

blue balls. So for  

14

red balls there are  

14    

----

2

A cooking show currently has about 223,00 regular viewers. The number of regular viewers has been decreasing at a rate of 4.7% p
Mazyrski [523]
The best prediction for the number of regular spectators that the program will have in 6 years is obtained with the following formula:
 Pf = Po×(1-b) ^ t
 Where:
 Pf = final population
 Po = initial population
 b = decrease rate
 t = timpo in years
 So:
 Pf = 223.00×(1-0.047) ^ 6
 Pf = 167,056
 The answer is the last option.

What is an equation of the line that passes through the points
zubka84 [21]

Answer <u>(assuming it can be in slope-intercept form): </u>

y = x - 5

Step-by-step explanation:

1) First, find the slope of the equation. Use the slope formula, m = \frac{y_2-y_1}{x_2-x_1}, and substitute the x and y values of the given points into it. Then, solve:

m = \frac{(2)-(1)}{(7)-(6)} \\m = \frac{2-1}{7-6} \\m = \frac{1}{1} \\m = 1

2) Now that we know the slope and at least one point the line crosses through, we can write an equation of the line in point-slope form, or y-y_1 = m (x-x_1). Substitute m, x_1, and y_1 for real values.

Since m represents the slope, substitute 1 for it. Since x_1 and y_1 represent the x and y values of a point the line intersects, use any one of the given points (either one is fine, either way the equation will represent the same line) and substitute its x and y values into the equation. (I chose the point (6, 1), as seen below.) Finally, isolate y to put the equation in slope-intercept form.

y-1 = 1(x-6)\\y -1 = x-6\\y = x -5
