55 mph minus 40 mph = 15 miles distance for each hour


So 5 hours * 15 = 75 miles difference after 5 hours

10. A cube has faces numbered 1 to 6. If you roll this cube 4 times, how many different outcomes are possible?
Georgia [21]

Answer: If we throw 4 cubes, there are 1296 different outcomes are possible.

Step-by-step explanation:

Given : A cube has faces numbered 1 to 6.

So the number of outcomes for throwing one die = 6

If we throw 4 cubes , then

According to the Fundamental counting principle,

The total number of different outcomes are possible =  (\text{Number of outcomes for throwing one die})^4

Therefore , The total number of different outcomes are possible =6^4=1296

Hence, there are 1296 different outcomes are possible.

What are the parameters of linear functions
xz_007 [3.2K]

Answer:

Algebraically, linear functions are a two parameter family. The parameter a is called the function's y-intercept and the parameter b is called the slope. Together, they completely determine a linear function's input-output behavior. Notice that f(0) = a : The y-intercept is the output when the input is 0.

Is each biconditional statement true or false?
Margarita [4]

Answer: 1. False

2. True

3. True

4.False


Step-by-step explanation:

1. False, because 6 is a multiple of 3 but 6 is not an odd number.

2. True, all even numbers are multiple of 2, and thus divisible by 2. Any number that is divisible by 2 must be a multiple of 2. hence,the given biconditional statement in true.

3. True, all multiples of 5 has 0 or 5 in the ones place.

Thus the given biconditional statement is true.

4.False, because 6 is not a multiple of 4 but 6 is not a prime number.

WILL GIVE BRAINLIEST TO BEST RESPONSE!
Monica [59]

You are given the X value, replace x with 2 in the first equation to solve for y:

y=2x +3

y = 2(2) +3

y = 4+3

y = 7

Now replace y with 7 and x iwth 2 in the second equation and solve for k:

y = -x +k

7 = -2 +k

Add 2 to both sides:

9 = k

so k = 9

The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.

K = 9
