Answer:

Step-by-step explanation:

Since the question is asking how long will it take him if he has to drive 240 miles and he drives 60 mph, this can be interpreted as division.

Now that we have converted the words into math, we are really solving 240 ÷ 60 or $\frac{240}{60}$ .

240 divided by 60 is the same as 24 divided by 6 because we can cancel the 0's.

Solving:

24 ÷ 6 = 4.

Thus, our answer is that it will take Charlie 4 hours to get to Dallas.

The graph of linear function f passes through the point (1, -9) and has a slope of -3. What is the zero of f ?

den301095 [7]

Answer:

-2

Step-by-step explanation:

The standard equation of a line is y = mx+c

m is the slope

c is the intercept

Given

Slope = -3

Get the intercept c;

Substitute m = -3 and (1, -9) into y = mx+c

-9 = -3(1) + c

-9 = -3 + c

c = -9 + 3

c = -6

The equation becomes

y = -3x + (-6)

y = -3x-6

f(x) = -3x-6

The zero of f occurs at f(x) = 0

0 = -3x-6

3x = -6

x = -6/3

x = -2

Hence the zero of the function is -2

A girl scout leader rented a bus for a trip to the museum. The bus company charged $275 plus $.35 for each mile traveled over 35

slava [35]

Answer: The trip was 440 miles

Step-by-step explanation:

A girl scout leader rented a bus for a trip to the museum.

Let x represent the number of miles

traveled over 350 miles.

Let y represent the total cost of travelling x miles

The bus company charged $275 plus $.35 for each mile traveled over 350 miles. This means that for x miles, the cost will be

y = 275 + 0.35x

If the bus trip cost $429, it means that y = 429

To determine the number of miles,we will substitute y = 429 into the equation. It becomes

429 = 275 + 0.35x

0.35x = 429 - 275 = 154

x = 154/0.35 = 440

x = 440 miles

, list the first five terms of each sequence, and identify them as arithmetic or geometric.

sveta [45]

Answer: -2, 2, 6, 10, 14

It is an Arithmetic sequence.

Step-by-step explanation:

Given Recursive formula : $A(n + 1) = A(n) + 4$ , for n ≥ 1 and A(1) = -2.

$A(2)=A(1 + 1) = A(1) + 4=-2+4=2$

$A(3)=A(2 + 1) = A(2) + 4=2+4=6$

$A(4)=A(3 + 1) = A(3) + 4=6+4=10$

$A(5)=A(4 + 1) = A(4) + 4=10+4=14$

Hence, the five terms of given sequence= -2, 2, 6, 10, 14

Since, there is common difference of 4 in two consecutive terms.

Therefore, it is an Arithmetic sequence.
