Answer: There are 12 white and blue cars more than silver and red cars

Number of white cars: n1=25
Number of blue cars: n2=17
Number of white and blue cars: n3=n1+n2=25+17→n3=42

Number of silver cars: n4=21
Number of red cars: n5=9
Number of silver and red cars: n6=n4+n5=21+9→n6=30

How many more white and blue cars are there than silver and red cars?
n=?

n=n3-n6=42-30→n=12

Answer: There are 12 white and blue cars more than silver and red cars.

A function of the form f(x)=ab^x is modified so that the b value remains the same but the a value is increased by 2. How do the
ANEK [815]

Answer:

The domain and range remain the same.

Step-by-step explanation:

Hi there!

First, we must determine what increasing <em>a</em> by 2 really does to the exponential function.

In f(x)=ab^x, <em>a</em> represents the initial value (y-intercept) of the function while <em>b</em> represents the common ratio for each consecutive value of f(x).

Increasing <em>a</em> by 2 means moving the y-intercept of the function up by 2. If the original function contained the point (0,x), the new function would contain the point (0,x+2).

The domain remains the same; it is still the set of all real x-values. This is true for any exponential function, regardless of any transformations.

The range remains the same as well; for the original function, it would have been y\neq 0. Because increasing <em>a</em> by 2 does not move the entire function up or down, the range remains the same.

I hope this helps!

A number minus 3 is 5. write and solve an equation to find the missing number
Mrac [35]

a number can be written a "x".

"minus" is a key word for subtraction.

"is" is a key word for =.

So if we put that all together, we have

x-3=5

To solve it, we have to add 3, to cancel it out, and add 3 to 5.

x-3=5

+3 +3

x=8

hope it helps
